blanchet@60306
    13
* Sledgehammer:
blanchet@60306
    14
  - Proof reconstruction has been improved, to minimize the incidence of
blanchet@60306
    15
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
    16
  - Auto Sledgehammer now minimizes and preplays the results.

*** General ***
wenzelm@57941
    23
wenzelm@59939
    24
* Local theory specification commands may have a 'private' or
wenzelm@59990
    25
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
    26
as provided by some "context begin ... end" block. For example:
wenzelm@59926
    27
wenzelm@59926
    28
  context
wenzelm@59926
    29
  begin
wenzelm@59926
    30
wenzelm@59926
    31
  private definition ...
wenzelm@59926
    32
  private lemma ...
wenzelm@59926
    33
wenzelm@59990
    34
  qualified definition ...
wenzelm@59990
    35
  qualified lemma ...
wenzelm@59990
    36
wenzelm@59926
    37
  lemma ...
wenzelm@59926
    38
  theorem ...
wenzelm@59926
    39
wenzelm@59926
    40
  end
wenzelm@59926
    41
wenzelm@59901
    42
* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
    43
naming policy.
wenzelm@59901
    44
wenzelm@59951
    45
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
    46
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
    47
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
    48
wenzelm@59951
    49
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
    50
together with an attribute to maintain the content incrementally. This
wenzelm@59951
    51
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
    52
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
    53
wenzelm@59951
    54
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
    55
schematically expanded before search. Search results match the naive
wenzelm@59951
    56
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
    57
INCOMPATIBILITY.
wenzelm@59648
    58
wenzelm@59569
    59
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
    60
theory context.
wenzelm@57941
    61
wenzelm@58928
    62
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
    63
context, without implicit global state. Potential for accidental
wenzelm@58928
    64
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
    65
wenzelm@60116
    66
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60116
    67
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60116
    68
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60116
    69
sources.
wenzelm@60116
    70
wenzelm@59951
    71
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
    72
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
    73
wenzelm@60119
    74
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
    75
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
    76
method provides basic fact/term matching in addition to
wenzelm@60119
    77
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
    78
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
    79
documentation provides an entry "eisbach" for the Eisbach User Manual.
wenzelm@60288
    80
Sources and various examples are in ~~/src/HOL/Eisbach/.

    83
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@58524
    84
wenzelm@59569
    85
* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
    86
the "sidekick" mode may be used for document structure.
wenzelm@59569
    87
wenzelm@59569
    88
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
    89
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
    90
in the buffer.
wenzelm@58758
    91
wenzelm@58540
    92
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
    93
marker, SideKick parser.
wenzelm@58524
    94
wenzelm@58551
    95
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
    96
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
    97
the editor (hyperlinks, completion etc.).
wenzelm@58551
    98
wenzelm@58785
    99
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   100
Options / Text Area).
wenzelm@58785
   101
wenzelm@60091
   102
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   103
display of 'thy_deps', 'class_deps' etc.
wenzelm@60010
   104
wenzelm@60116
   105
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60116
   106
restrict the visualized hierarchy.
wenzelm@60095
   107
wenzelm@60072
   108
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
   109
managed by the Sledgehammer panel) wrt. ongoing document processing.
wenzelm@60072
   110
wenzelm@58524
   111
wenzelm@59951
   112
*** Document preparation ***
wenzelm@59951
   113
wenzelm@59951
   114
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   115
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   116
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   117
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   118
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   119
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   120
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   121
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   122
wenzelm@60010
   123
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60010
   124
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60010
   125
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60010
   126
as argument to other macros (such as footnotes).
wenzelm@60010
   127
wenzelm@60010
   128
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60010
   129
style.
wenzelm@60010
   130
wenzelm@60010
   131
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60010
   132
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60010
   133
wenzelm@59951
   134
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   135
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   136
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   137
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   138
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   139
wenzelm@59951
   140
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   141
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   142
Only the margin for document output may be changed, but not the global
wenzelm@59951
   143
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   144
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   145
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   146
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   147
wenzelm@60299
   148
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   149
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
   150
copying of the document/ directory is no longer supported. Minor
wenzelm@60299
   151
INCOMPATIBILITY.
wenzelm@60299
   152
wenzelm@59951
   153
haftmann@58202
   154
*** Pure ***
haftmann@58202
   155
wenzelm@59835
   156
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   157
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   158
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   159
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   160
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   161
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   162
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   163
variable declarations or dummy patterns instead.
wenzelm@59835
   164
wenzelm@60010
   165
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60010
   166
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60010
   167
("_") that stand for anonymous local variables.
wenzelm@60010
   168
wenzelm@59951
   169
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   170
incremented to avoid material in the proof context. Rare
wenzelm@59951
   171
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   172
different index.
wenzelm@59951
   173
wenzelm@60011
   174
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60011
   175
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60011
   176
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60011
   177
like "(- 1) ^ n".
haftmann@58410
   178
wenzelm@58421
   179
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
   180
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
   181
token category instead.

*** HOL ***
blanchet@57737
   185
blanchet@57983
   186
* New (co)datatype package:
blanchet@58374
   187
  - The 'datatype_new' command has been renamed 'datatype'. The old
blanchet@58374
   188
    command of that name is now called 'old_datatype' and is provided
blanchet@58374
   189
    by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58374
   190
    'isabelle doc datatypes' for information on porting.
blanchet@58374
   191
    INCOMPATIBILITY.
blanchet@57983
   192
  - Renamed theorems:
blanchet@57983
   193
      disc_corec ~> corec_disc
blanchet@57983
   194
      disc_corec_iff ~> corec_disc_iff
blanchet@57983
   195
      disc_exclude ~> distinct_disc
blanchet@57983
   196
      disc_exhaust ~> exhaust_disc
blanchet@57983
   197
      disc_map_iff ~> map_disc_iff
blanchet@57983
   198
      sel_corec ~> corec_sel
blanchet@57983
   199
      sel_exhaust ~> exhaust_sel
blanchet@57983
   200
      sel_map ~> map_sel
blanchet@57983
   201
      sel_set ~> set_sel
blanchet@57983
   202
      sel_split ~> split_sel
blanchet@57983
   203
      sel_split_asm ~> split_sel_asm
blanchet@57983
   204
      strong_coinduct ~> coinduct_strong
blanchet@57983
   205
      weak_case_cong ~> case_cong_weak
blanchet@57983
   206
    INCOMPATIBILITY.
blanchet@58192
   207
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192
   208
    "codatatype" has been renamed "plugins del: code".
blanchet@58192
   209
    INCOMPATIBILITY.
blanchet@58044
   210
  - The rules "set_empty" have been removed. They are easy
blanchet@58044
   211
    consequences of other set rules "by auto".
blanchet@58044
   212
    INCOMPATIBILITY.
blanchet@58044
   213
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
   214
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
   215
    method when more than one case rule is applicable (e.g., an
blanchet@57990
   216
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   217
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
   218
    (e.g. "cases w rule: widget.exhaust").
blanchet@57990
   219
    INCOMPATIBILITY.
blanchet@59675
   220
  - Renamed theories:
blanchet@59675
   221
      BNF_Comp ~> BNF_Composition
blanchet@59675
   222
      BNF_FP_Base ~> BNF_Fixpoint_Base
blanchet@59675
   223
      BNF_GFP ~> BNF_Greatest_Fixpoint
blanchet@59675
   224
      BNF_LFP ~> BNF_Least_Fixpoint
blanchet@59675
   225
      BNF_Constructions_on_Wellorders ~> BNF_Wellorder_Constructions
blanchet@59675
   226
      Cardinals/Constructions_on_Wellorders ~> Cardinals/Wellorder_Constructions
blanchet@59675
   227
    INCOMPATIBILITY.
wenzelm@60115
   228
  - Lifting and Transfer setup for basic HOL types sum and prod (also
wenzelm@60115
   229
    option) is now performed by the BNF package. Theories Lifting_Sum,
wenzelm@60115
   230
    Lifting_Product and Lifting_Option from Main became obsolete and
wenzelm@60115
   231
    were removed. Changed definitions of the relators rel_prod and
wenzelm@60115
   232
    rel_sum (using inductive).
traytel@60112
   233
    INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead
wenzelm@60115
   234
    of rel_prod_def and rel_sum_def.
wenzelm@60115
   235
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60115
   236
    changed (e.g. map_prod_transfer ~> prod.map_transfer).
wenzelm@60261
   237
  - Parametricity theorems for map functions, relators, set functions,
wenzelm@60261
   238
    constructors, case combinators, discriminators, selectors and
wenzelm@60261
   239
    (co)recursors are automatically proved and registered as transfer
wenzelm@60261
   240
    rules.
blanchet@57983
   241
blanchet@57983
   242
* Old datatype package:
blanchet@58310
   243
  - The old 'datatype' command has been renamed 'old_datatype', and
blanchet@58374
   244
    'rep_datatype' has been renamed 'old_rep_datatype'. They are
blanchet@58374
   245
    provided by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58310
   246
    'isabelle doc datatypes' for information on porting.
blanchet@58374
   247
    INCOMPATIBILITY.
blanchet@57983
   248
  - Renamed theorems:
blanchet@57983
   249
      weak_case_cong ~> case_cong_weak
blanchet@57983
   250
    INCOMPATIBILITY.
blanchet@58374
   251
  - Renamed theory:
blanchet@58374
   252
      ~~/src/HOL/Datatype.thy ~> ~~/src/HOL/Library/Old_Datatype.thy
blanchet@58374
   253
    INCOMPATIBILITY.
blanchet@57983
   254
blanchet@59039
   255
* Nitpick:
wenzelm@60011
   256
  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   257
    operations.
blanchet@59039
   258
blanchet@57737
   259
* Sledgehammer:
blanchet@59511
   260
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   261
    default.
blanchet@59965
   262
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   263
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
   264
  - Minimization is now always enabled by default.
wenzelm@60011
   265
    Removed sub-command:
blanchet@57737
   266
      min
blanchet@59967
   267
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039
   268
    dramatically improved.
blanchet@59039
   269
  - Improved support for CVC4 and veriT.
blanchet@57737
   270
blanchet@58062
   271
* Old and new SMT modules:
blanchet@58067
   272
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   273
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   274
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   275
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   276
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
   277
    point to it.
blanchet@58062
   278
    INCOMPATIBILITY.
blanchet@58067
   279
  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
   280
    INCOMPATIBILITY.
wenzelm@59569
   281
  - New option 'smt_reconstruction_step_timeout' to limit the
wenzelm@59569
   282
    reconstruction time of Z3 proof steps in the new 'smt' method.
boehmes@59216
   283
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
   284
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060
   285
wenzelm@60261
   286
* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
   287
that have as a return type a datatype containing a subtype. This
wenzelm@60261
   288
overcomes long-time limitations in the area of code generation and
wenzelm@60261
   289
lifting, and avoids tedious workarounds.
kuncar@60258
   290
wenzelm@60010
   291
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60010
   292
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60010
   293
Minor INCOMPATIBILITY.
wenzelm@60010
   294
wenzelm@60010
   295
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60010
   296
wenzelm@60010
   297
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60010
   298
non-termination in case of distributing a division. With this change
wenzelm@60010
   299
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60010
   300
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60010
   301
wenzelm@60010
   302
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60010
   303
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60010
   304
wenzelm@60010
   305
* Class linordered_semidom really requires no zero divisors.
wenzelm@60010
   306
INCOMPATIBILITY.
wenzelm@60010
   307
wenzelm@60010
   308
* Classes division_ring, field and linordered_field always demand
wenzelm@60010
   309
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60010
   310
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60010
   311
wenzelm@60010
   312
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit
wenzelm@60010
   313
additive inverse operation. INCOMPATIBILITY.
wenzelm@60010
   314
lp15@60020
   315
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
   316
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
   317
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
   318
wenzelm@60010
   319
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60010
   320
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60010
   321
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60010
   322
needed.
wenzelm@60010
   323
wenzelm@60010
   324
* New library of properties of the complex transcendental functions sin,
wenzelm@60010
   325
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60010
   326
wenzelm@60010
   327
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60010
   328
that admits numeric types including nat, int, real and complex.
wenzelm@60010
   329
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60010
   330
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60010
   331
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60010
   332
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60010
   333
wenzelm@60010
   334
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60010
   335
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60010
   336
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60010
   337
"nat_floor"/"nat_ceiling".
wenzelm@60010
   338
wenzelm@60010
   339
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60010
   340
type class hierarchy:
wenzelm@60010
   341
  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60010
   342
  field_inverse_zero ~> inverse_zero
wenzelm@60010
   343
  field_divide_inverse ~> divide_inverse
wenzelm@60010
   344
  field_inverse ~> left_inverse
wenzelm@60010
   345
Minor INCOMPATIBILITY.
wenzelm@60010
   346
wenzelm@60010
   347
* Eliminated fact duplicates:
wenzelm@60010
   348
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60010
   349
  mult_less_imp_less_left ~> mult_left_less_imp_less
wenzelm@60010
   350
Minor INCOMPATIBILITY.
wenzelm@60010
   351
wenzelm@60010
   352
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60010
   353
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60010
   354
wenzelm@60010
   355
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60010
   356
  dvd_reduce ~> dvd_add_triv_right_iff
wenzelm@60010
   357
  dvd_plus_eq_right ~> dvd_add_right_iff
wenzelm@60010

wenzelm@60010
   359
Minor INCOMPATIBILITY.
wenzelm@60010
   360
wenzelm@60010
   361
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"
wenzelm@60010
   362
and part of theory Main.
wenzelm@60010
   363
  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60010
   364
INCOMPATIBILITY.
wenzelm@60010
   365
wenzelm@60010
   366
* Lemma name consolidation: divide_Numeral1 ~> divide_numeral_1. Minor
wenzelm@60010
   367
INCOMPATIBILITY.
wenzelm@60010
   368
wenzelm@60010
   369
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60010
   370
Fact rename:
wenzelm@60010
   371
    listsum_def ~> listsum.eq_foldr
wenzelm@60010
   372
INCOMPATIBILITY.
wenzelm@60010
   373
wenzelm@60010
   374
* Product over lists via constant "listprod".
wenzelm@60010
   375
wenzelm@60010
   376
* Theory List: renamed drop_Suc_conv_tl and nth_drop' to
wenzelm@60010
   377
Cons_nth_drop_Suc.
nipkow@58247

Andreas@58626
   379
* New infrastructure for compiling, running, evaluating and testing
wenzelm@59569
   380
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
   381
HOL/Codegenerator_Test/Code_Test* for examples.
wenzelm@58008
   382
wenzelm@60010
   383
* Library/Multiset:
blanchet@59813
   384
  - Introduced "replicate_mset" operation.
blanchet@59813
   385
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
   386
    "Library/Multiset_Order".
blanchet@59958
   387
  - Renamed multiset ordering:

    INCOMPATIBILITY.
blanchet@59986

   394
      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
   395
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986
   396
    INCOMPATIBILITY.
blanchet@59813
   397
  - Renamed
blanchet@59813

    INCOMPATIBILITY.
nipkow@59949
   402
  - Removed mcard, is equal to size.
blanchet@59813

    INCOMPATIBILITY.
blanchet@59813
   413
wenzelm@60010
   414
* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60010
   415
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60010
   416
The "sos_cert" functionality is invoked as "sos" with additional
wenzelm@60010
   417
argument. Minor INCOMPATIBILITY.
wenzelm@60010
   418
wenzelm@60010
   419
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60010
   420
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60010
   421
hardware floating point arithmetic to randomly discover potential
wenzelm@60011
   422
counterexamples. Counterexamples are certified with the "approximation"
wenzelm@60010

wenzelm@60010
   424
examples.

* HOL-Probability: Reworked measurability prover
wenzelm@60011
   427
  - applies destructor rules repeatedly
hoelzl@59354
   428
  - removed application splitting (replaced by destructor rule)
wenzelm@59569
   429
  - added congruence rules to rewrite measure spaces under the sets

   430
    projection
wenzelm@59569
   431
wenzelm@60010

   436
*** ML ***
blanchet@58066
   437
wenzelm@60010
   438
* Subtle change of name space policy: undeclared entries are now
wenzelm@60010
   439
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60010
   440
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60010
   441
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60011
   442
contemporary applications use the strict Name_Space.check (and
wenzelm@60010
   443
derivatives) instead, which is not affected by the change. Potential
wenzelm@60010
   444
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
   445
wenzelm@60096
   446
* Subtle change of error semantics of Toplevel.proof_of: regular user
wenzelm@60096
   447
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60096
   448
wenzelm@59951
   449
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
   450
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
   451
wenzelm@59951
   452
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
   453
INCOMPATIBILITY.
wenzelm@59951
   454
wenzelm@59951
   455
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
   456
sections have been discontinued, in favour of the more elementary
wenzelm@59951
   457
Multithreading.synchronized and its high-level derivative
wenzelm@59951
   458
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
   459
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
   460
nested.
wenzelm@59951
   461
wenzelm@60010
   462
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60010
   463
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
   464
wenzelm@59621
   465
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
   466
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
   467
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
   468
INCOMPATIBILITY.
wenzelm@59621
   469
wenzelm@59582
   470
* Elementary operations in module Thm are no longer pervasive.
wenzelm@59582
   471
INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,

   472
Thm.term_of etc.
wenzelm@59582
   473
wenzelm@58963
   474
* Proper context for various elementary tactics: assume_tac,
wenzelm@59498
   475
resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498
   476
compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
   477
blanchet@58066
   478
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
   479
PARALLEL_GOALS.
blanchet@58066
   480
wenzelm@59564
   481
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
   482
which also allows to specify a fork priority.
wenzelm@59564
   483
wenzelm@59936
   484
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936
   485
@{command_keyword COMMAND} (usually without quotes and with PIDE
wenzelm@59936
   486

   534
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   535
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   536
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   537
induction is done after these methods or when the names of free and
wenzelm@57504
   538
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   539
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   540
wenzelm@56232
   541
* More static checking of proof methods, which allows the system to
wenzelm@56232
   542
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
   543
processed in the original proof context as far as possible, before
wenzelm@56232
   544
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   545
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   546
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   547
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   548
proof tools.
wenzelm@56232
   549
wenzelm@57452
   550
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   551
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   552
supports input via ` (backquote).
wenzelm@57452
   553
wenzelm@57452
   554
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   555
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   556
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   557
wenzelm@57452
   558
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   559
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   560
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   561
Minor INCOMPATIBILITY.
wenzelm@57452
   562
wenzelm@57452
   563
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   564
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   565
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   566
INCOMPATIBILITY.
wenzelm@57452
   567
wenzelm@57452
   568
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   569
which results in an active hyperlink within the text.
wenzelm@57452
   570
wenzelm@57452
   571
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   572
not check existence within the file-system.
wenzelm@57452
   573
wenzelm@57452
   574
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   575
isar-ref, jedit, system.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   579
wenzelm@57650
   580
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   581
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   582
buffer.
wenzelm@57452
   583
wenzelm@57452
   584
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   585
to PIDE hyperlinks.
wenzelm@57452
   586
wenzelm@57452
   587
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   588
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   589
wenzelm@57452
   590
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   591
auxiliary ML files.
wenzelm@57423
   592
wenzelm@57423
   593
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   594
templates, completion language context, name-space completion,
wenzelm@57423
   595
file-name completion, spell-checker completion.
wenzelm@57423
   596
wenzelm@57423
   597
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   598
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   599
keystrokes with slow / remote graphics displays.
wenzelm@57423
   600
wenzelm@57833
   601
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   602
item, depending on Isabelle options.
wenzelm@57833
   603
wenzelm@57423
   604
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   605
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   606
caret".
wenzelm@56342
   607
wenzelm@56580
   608
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   609
completion popup and context-menu.
wenzelm@56554
   610
wenzelm@56879
   611
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   612
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   613
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   614
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   615
wenzelm@56901
   616
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   617
to highlight text via regular expression.
wenzelm@56901
   618
wenzelm@54881
   619
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   620
General") allows to specify additional print modes for the prover
wenzelm@54881
   621
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   622
"isabelle jedit -m MODE".
wenzelm@54881
   623
wenzelm@56505
   624
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   625
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   626
wenzelm@57822
   627
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   628
imports) are automatically removed from the document model.
wenzelm@57822
   629
wenzelm@57869
   630
* Improved monitor panel.
wenzelm@57869
   631
wenzelm@56838
   632
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   633
more robust treatment of threads and interrupts.
wenzelm@56838
   634
wenzelm@56939
   635
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   636
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   637
"Detach" a copy where this makes sense.
wenzelm@56939
   638
wenzelm@57452
   639
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57594
   640
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
   641
within the context.

*** Pure ***
wenzelm@55001
   645
wenzelm@57504
   646
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
   647
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
   648
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
   649
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
   650
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
   651
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
   652
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
   653
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
   654
Axclass.arity_axiomatization.
wenzelm@57504
   655
wenzelm@56245
   656
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   657
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   658
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   659
renaming needs to be applied:
wenzelm@56245
   660
wenzelm@56245
   661
  ==             ~>  Pure.eq
wenzelm@56245
   662
  ==>            ~>  Pure.imp
wenzelm@56245
   663
  all            ~>  Pure.all
wenzelm@56245
   664
  TYPE           ~>  Pure.type
wenzelm@56245
   665
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   666
wenzelm@56245
   667
Systematic porting works by using the following theory setup on a
wenzelm@56245
   668
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   669
old constants:
wenzelm@56245
   670
wenzelm@56245
   671
setup {*
wenzelm@56245
   672
  fn thy => thy
wenzelm@56245
   673
    |> Sign.root_path
wenzelm@56245
   674
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   675
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   676
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   677
    |> Sign.restore_naming thy
wenzelm@56245
   678
*}
wenzelm@56245
   679
wenzelm@56245
   680
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   681
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   682
the auxiliary aliases are deleted.
wenzelm@56245
   683
wenzelm@55143
   684
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   685
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   686
instantiated theorem.
wenzelm@55143
   687
wenzelm@55152
   688
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
   689
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
   690
where instantiations with schematic variables are intended (for
wenzelm@55152
   691
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
   692
following temporary definition may help to port old applications:
wenzelm@55152
   693
wenzelm@55152
   694
  attribute_setup standard =
wenzelm@55152
   695
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
   696
wenzelm@55001
   697
* More thorough check of proof context for goal statements and
wenzelm@55006
   698
attributed fact expressions (concerning background theory, declared
wenzelm@55006
   699
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
   700
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
   701
primitive Thm.assume_hyps.
wenzelm@55001
   702
wenzelm@55108
   703
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
   704
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
   705
differently, e.g. via cartouches).
wenzelm@57452
   706
wenzelm@57504
   707
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
   708
but the latter is retained some time as Proof General legacy.
wenzelm@57504
   709
wenzelm@57452
   710
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
   711
per-constant basis.  See attribute "code_preproc".

wenzelm@57452
   739
wenzelm@57504

* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
   741
wenzelm@57504
   742
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504

to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504

wenzelm@57452
   747
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
   748
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
   749
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
   750
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
   751
again in the future.  INCOMPATIBILITY.

wenzelm@55139

* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
   906
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
   907
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
   908
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
   909
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
   910
corresponding tactics; the old default can be restored using "declare
wenzelm@57508

[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508

wenzelm@57508
   913
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
   914
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
   915
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
   916
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
   917
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
   918
wenzelm@57508
   919
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
   920
(without requiring restart), instead of former settings variable
wenzelm@57508
   921
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

* Sledgehammer:
wenzelm@57508
   925
  - Z3 can now produce Isar proofs.
wenzelm@57508
   926
  - MaSh overhaul:
blanchet@57532
   927
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
   928
      Python and increase performance and reliability.
wenzelm@57508
   929
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
   930
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
   931
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
   932
      Options / Isabelle / General to "none".
wenzelm@57508
   933
  - New option:
wenzelm@57508
   934
      smt_proofs
wenzelm@57508

wenzelm@57508
   940
wenzelm@57508

* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
   942
wenzelm@57508
   943
* Nitpick:
wenzelm@57508
   944
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
   945
    take infinite values.
wenzelm@57508
   946
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
   947
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
   948
  - Removed "std" option.
wenzelm@57508
   949
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
   950
    "hide_types".
wenzelm@57508
   951
wenzelm@57508
   952
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
   953
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
   954
wenzelm@57508
   955
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
   956
wenzelm@57508
   957
* Adjustion of INF and SUP operations:
wenzelm@57508
   958
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
   959
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
   960
    SUP instead uniformly.
wenzelm@57508
   961
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
   962
    or SUP and Sup.
wenzelm@57508
   963
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
   964
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
   965
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
   966
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508
   967
    INT_cong, SUP_cong

wenzelm@57508
   969
INCOMPATIBILITY.
wenzelm@57508

* SUP and INF generalized to conditionally_complete_lattice.
wenzelm@57508
   972
wenzelm@57508
   973
* Swapped orientation of facts image_comp and vimage_comp:

* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  1511
compared (according to Thm.thm_ord), but assumed to be covered by the

branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504

  1538
wenzelm@56281
  1539
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  1540
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  1541
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  1542
INCOMPATIBILITY.
wenzelm@56279
  1543
wenzelm@54449
  1544
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  1545
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  1546
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  1547
formal context.
wenzelm@54449
  1548
wenzelm@56205
  1549
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  1550
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  1551
wenzelm@56071
  1552
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  1553
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  1554
wenzelm@56135
  1555
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  1556
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1557
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1558
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  1559
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  1560
wenzelm@56399
  1561
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  1562
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  1563
purposes.

* Proof General with its traditional helper scripts is now an optional
wenzelm@57504
  1569
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  1570
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  1571
the "system" manual provides general explanations about add-on
wenzelm@57504
  1572
components, especially those that are not bundled with the release.
wenzelm@57443
  1573
wenzelm@56439
  1574
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  1575
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  1576
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  1577
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  1578
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  1579
settings variable.
wenzelm@56439
  1580
wenzelm@57439
  1581
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1582
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1583
obsolete Isar TTY loop.
wenzelm@57439
  1584
wenzelm@57452
  1585
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1586
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1587
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1588
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1589
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1590
wenzelm@57413
  1591
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1592
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1593
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1594
wenzelm@57452
  1595
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1596
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1597
wenzelm@57452
  1598
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1599
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1600
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1601
wenzelm@57452
  1602
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1603
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1604
files are copied to the document output directory, before document
wenzelm@57452
  1605
processing is started.
wenzelm@57452
  1606
wenzelm@57504
  1607
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  1608
of TeX Live from Cygwin.

wenzelm@54639
  1617
* More robust editing of running commands with internal forks,
wenzelm@54639
  1618
e.g. non-terminating 'by' steps.
wenzelm@54639
  1619
wenzelm@54641
  1620
* More relaxed Sledgehammer panel: avoid repeated application of query

  1621
after edits surrounding the command location.
wenzelm@54641
  1622
wenzelm@54648
  1623
* More status information about commands that are interrupted
wenzelm@54648

  1625
e.g. out-of-memory).

wenzelm@51293
  1644
*** General ***
wenzelm@51293
  1645
wenzelm@53971
  1646
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  1647
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  1648
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  1649
wenzelm@53971
  1650
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
  1651
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1652
wenzelm@53016
  1653
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1654
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1655
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1656
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  1657
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1658
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  1659
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1660
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  1661
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  1662
syntax.
wenzelm@53016
  1663
wenzelm@53021
  1664
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  1665
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  1666
wenzelm@52487
  1667
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1668
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1669
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1670
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1671
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1672
wenzelm@52060
  1673
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  1674
INCOMPATIBILITY.
wenzelm@52060
  1675
wenzelm@52430
  1676
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1677
implicit change of some global references) is retained for now as
wenzelm@52430
  1678
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1679
wenzelm@52549
  1680
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1681
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1682
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1683
wenzelm@53971
  1684
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
  1685
eliminated old "ref" manual.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
  1689
wenzelm@53971
  1690
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
  1691
Documentation panel.
wenzelm@53852
  1692
wenzelm@53971
  1693
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  1694
documentation.
wenzelm@52646
  1695
wenzelm@52949
  1696
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  1697
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  1698
wenzelm@53050
  1699
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  1700
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  1701
normal editing and checking process.
wenzelm@53050
  1702
wenzelm@51533
  1703
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  1704
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  1705
same timing information is shown in the extended tooltip of the
wenzelm@54332
  1706
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  1707
COMMAND modifier is pressed.
wenzelm@51533
  1708
wenzelm@53971
  1709
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  1710
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  1711
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  1712
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  1713
or shortcut "C+e SPACE".
wenzelm@53971
  1714
wenzelm@54305
  1715
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  1716
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  1717
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  1718
wenzelm@54319
  1719
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  1720
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  1721
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  1722
to resolve conflict.
wenzelm@54319
  1723
wenzelm@54305
  1724
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  1725
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  1726
wenzelm@53971
  1727
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  1728
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  1729
such command executions while editing.
wenzelm@53271
  1730
wenzelm@53971
  1731
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  1732
document content.
wenzelm@53971
  1733
wenzelm@53971
  1734
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  1735
toplevel theorem statements.
wenzelm@53971
  1736
wenzelm@53971
  1737
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  1738
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  1739
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  1740
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  1741
wenzelm@53971
  1742
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  1743
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  1744
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  1745
wenzelm@53971
  1746
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  1747
/ Global Options / Appearance".
wenzelm@53971
  1748
wenzelm@53971
  1749
* Improved support of native Mac OS X functionality via "MacOSX"

ballarin@54049
  1755
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  1756
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  1757
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  1758
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  1759
details.
haftmann@51747
  1760
ballarin@51565
  1761
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  1762
wenzelm@51313
  1763
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  1764
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  1765
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  1766
wenzelm@51316
  1767
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  1768
INCOMPATIBILITY.
wenzelm@51316
  1769
wenzelm@53971
  1770
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  1771
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  1772
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  1773
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  1774
wenzelm@53971
  1775
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  1776
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  1777
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  1778
wenzelm@53971
  1779
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  1780
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  1781
wenzelm@52463
  1782
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463

wenzelm@54032
  1791
INCOMPATIBILITY.
wenzelm@54032
  1792
wenzelm@54032
  1793
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  1794
wenzelm@54032
  1795
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  1796
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  1797
from the datatype package. The declaration attribute
wenzelm@54032
  1798
"case_translation" can be used to register new case combinators:
wenzelm@54032
  1799
wenzelm@54032
  1800
  declare [[case_translation case_combinator constructor1 ... constructorN]]

* Code generator:
wenzelm@53160
  1803
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  1804
    'code_instance'.
wenzelm@53160
  1805
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  1806
    generated code, subsuming 'code_modulename'.
wenzelm@53983

* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  1812

wenzelm@54032
  1813
to distinguish both when desired.
wenzelm@54032
  1814
wenzelm@54032

* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  1821
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  1822
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  1823
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  1824
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  1825
ML).  INCOMPATIBILITY.
wenzelm@54032
  1826
wenzelm@54032
  1827
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  1828
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  1829
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  1830
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  1831
wenzelm@54032
  1832
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  1833
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  1834
wenzelm@54032
  1835
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  1836
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  1837
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.

kuncar@54021
  1839
* Lifting:
kuncar@54021
  1840
  - parametrized correspondence relations are now supported:
wenzelm@54378
  1841
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  1842
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  1843
      transfer rules
kuncar@54021
  1844
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  1845
      correspondence relation can be generated
kuncar@54021
  1846
    + various new properties of the relator must be specified to support
kuncar@54021
  1847
      parametricity
kuncar@54021
  1848
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  1849
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  1850
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  1851
    copies
kuncar@54021
  1852
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  1853
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  1854
    anonymous context)
wenzelm@54378
  1855
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  1856
    Main. Potential INCOMPATIBILITY
kuncar@54021
  1857
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  1858
    lifting_forget, lifting_update
wenzelm@54378
  1859
  - the command print_quotmaps was renamed to print_quot_maps.

  1860
    INCOMPATIBILITY
kuncar@54021
  1861
kuncar@54021
  1862
* Transfer:
wenzelm@54378
  1863
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  1864
    by the actual invariant in a transferred goal
kuncar@54021
  1865
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  1866
  - Experimental support for transferring from the raw level to the
kuncar@54021
  1867
    abstract level: Transfer.transferred attribute
kuncar@54021
  1868
  - Attribute version of the transfer method: untransferred attribute

* Reification and reflection:
wenzelm@53160
  1871
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  1872
    "Reification".
wenzelm@53160
  1873
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  1874
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  1875
INCOMPATIBILITY.
haftmann@52286
  1876
haftmann@51489
  1877
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  1878
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  1879
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  1880
    This is now identity on infinite sets.
wenzelm@52745
  1881
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  1882
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  1883
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  1884
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  1885
    See theory Big_Operators for canonical examples.
haftmann@51489
  1886
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  1887
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  1888
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  1889
    those foundational constants as substitutes, but it is
wenzelm@53983
  1890
    preferable to interpret the above locales accordingly.
haftmann@51489
  1891
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  1892
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  1893
  - Fact renames:
haftmann@51489
  1894
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  1895
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  1896
INCOMPATIBILITY.
haftmann@51489
  1897
haftmann@51487
  1898
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  1899
wenzelm@53526
  1900
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  1901
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  1902
class predicate assumption or sort constraint when possible.
Andreas@53362
  1903
INCOMPATIBILITY.
Andreas@53362
  1904
wenzelm@53160
  1905
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  1906
complete lattice but does not assume the existence of the top and
wenzelm@53160
  1907
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  1908
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  1909
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  1910
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  1911
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  1912
lemmas.
wenzelm@53160
  1913
wenzelm@53160
  1914
* Introduce type class linear_continuum as combination of
wenzelm@53160
  1915
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  1916
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  1917
wenzelm@53983
  1918
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  1919
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  1920
Rename bot -> order_bot, top -> order_top
lammich@53683
  1921
wenzelm@53160
  1922
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  1923
top and bottom elements.
hoelzl@51732
  1924
hoelzl@51732
  1925
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  1926
hoelzl@51732
  1927
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  1928
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  1929
wenzelm@53983
  1930
 - Introduce type class (lin)order_topology and
wenzelm@53983
  1931
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  1932
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  1933
hoelzl@51732
  1934
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  1935
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  1936
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  1937
wenzelm@53983
  1938
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  1939
   arbitrary filter.
wenzelm@53983
  1940
wenzelm@53983
  1941
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  1942
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  1943
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  1944
   continuous function is continuous, when the function is continuous
wenzelm@53983
  1945
   on a compact set.
hoelzl@51732
  1946
hoelzl@51732
  1947
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  1948
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  1949
   linear_continuum_topology).
hoelzl@51732
  1950
hoelzl@51732
  1951
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  1952
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  1953
   on all sequences converging to x.
wenzelm@53983
  1954
wenzelm@53983
  1955
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  1956
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  1957
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  1958
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  1959
   left or right.
hoelzl@51732
  1960
hoelzl@51732
  1961
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  1962
hoelzl@51732
  1963
     F within X = inf F (principal X)
hoelzl@51732
  1964
hoelzl@51732
  1965
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  1966
   abbreviation for "at x within UNIV"
hoelzl@51732
  1967
wenzelm@53983
  1968
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  1969
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  1970
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  1971
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  1972
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  1973
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  1974
hoelzl@51732
  1975
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  1976
hoelzl@51732
  1977
   + Moved RealDef and RComplete into Real
hoelzl@51732
  1978
hoelzl@51732
  1979
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  1980
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  1981
hoelzl@51732
  1982
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  1983
wenzelm@53983
  1984
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  1985
     Real_Vector_Spaces, and Limits
hoelzl@51732
  1986
hoelzl@51732
  1987
   + Moved Ln and Log to Transcendental
hoelzl@51732
  1988
hoelzl@51732
  1989
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  1990
hoelzl@51732

* Library/Polynomial.thy:
wenzelm@54032
  2011
  - Use lifting for primitive definitions.
wenzelm@54032

  2085
INCOMPATIBILITY.
wenzelm@53164
  2086
wenzelm@51551
  2087
* More uniform naming of goal functions for skipped proofs:
wenzelm@51551
  2088
wenzelm@51551
  2089
    Skip_Proof.prove  ~>  Goal.prove_sorry
wenzelm@51551
  2090
    Skip_Proof.prove_global  ~>  Goal.prove_sorry_global
wenzelm@51551
  2091
wenzelm@53971
  2092
Minor INCOMPATIBILITY.
wenzelm@51703
  2093
wenzelm@51717
  2094
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
  2095
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
  2096
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
  2097
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
  2098
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
  2099
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
  2100
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
  2101
wenzelm@53971
  2102
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  2103
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
  2104
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
  2105
clasets separately from the context.
wenzelm@53971
  2106
wenzelm@51717
  2107
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.
wenzelm@51717
  2108
INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
  2109
wenzelm@53971
  2110
* Antiquotation @{theory_context A} is similar to @{theory A}, but
wenzelm@53971
  2111
presents the result as initial Proof.context.

wenzelm@52746
  2127
always pdf.
wenzelm@52743

wenzelm@52053
  2129
* Isabelle settings variable ISABELLE_BUILD_JAVA_OPTIONS allows to
wenzelm@52053
  2130
specify global resources of the JVM process run by isabelle build.
wenzelm@52053
  2131
wenzelm@52116
  2132
* Toplevel executable $ISABELLE_HOME/bin/isabelle_scala_script allows

  2133
to run Isabelle/Scala source files as standalone programs.
wenzelm@52116
  2134
wenzelm@52439
  2135
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
  2136
keyword tables): use Isabelle/Scala operations, which inspect outer
wenzelm@52439
  2137
syntax without requiring to build sessions first.
wenzelm@52439
  2138
wenzelm@53971
  2139
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971

wenzelm@53971
  2141
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
  2142
tendency towards erratic fluctuation of URLs) has been discontinued.

*** General ***
wenzelm@47967
  2152
wenzelm@50126
  2153
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  2154
no longer printed by default, since it is incompatible with
wenzelm@50126
  2155
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  2156
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  2157
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  2158
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  2159
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  2160
wenzelm@49699
  2161
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  2162
into the printed representation of formal entities --- notably type
wenzelm@49699
  2163
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  2164
information via tooltips in the output window, for example.
wenzelm@49699
  2165
wenzelm@48890
  2166
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  2167
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  2168
wenzelm@49243
  2169
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  2170
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  2171
Tools that load their additional source files may imitate the
wenzelm@49243
  2172
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  2173
dependencies properly.
wenzelm@49243
  2174
wenzelm@47967
  2175
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  2176
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  2177
wenzelm@50110
  2178
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  2179
remaining material in old "ref" manual.
wenzelm@48120
  2180
wenzelm@51050
  2181
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  2182
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  2183
and "class ... context ...".
wenzelm@49841
  2184
wenzelm@50772
  2185
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  2186
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  2187
the target context.  This form of declaration is stable when exported
wenzelm@50772
  2188
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  2189
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  2190
in HOL/inductive and HOL/function.
wenzelm@50772
  2191
wenzelm@49869
  2192
* More informative error messages for Isar proof commands involving
wenzelm@49869
  2193
lazy enumerations (method applications etc.).
wenzelm@49869
  2194
wenzelm@50213
  2195
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  2196
to name patterns (with clickable results).

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  2200
wenzelm@49968
  2201
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  2202
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  2203
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  2204
surface, while the prover is still crunching on internal
wenzelm@49968
  2205
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  2206
required to complete full proof checking eventually.
wenzelm@49968
  2207
wenzelm@49968
  2208
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  2209
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  2210
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  2211
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  2212
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  2213
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  2214
wenzelm@50717
  2215
* Improved support for commands that produce graph output: the text
wenzelm@50717
  2216
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  2217
browser on demand.
wenzelm@50717
  2218
wenzelm@49968
  2219
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  2220
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  2221
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  2222
that frequently occur in user interaction.
wenzelm@49968
  2223
wenzelm@49968
  2224
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  2225
files.  More scalable management of formal document content.
wenzelm@49968
  2226
wenzelm@50505
  2227
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  2228
certain number of messages per command transaction, with some user
wenzelm@50505
  2229
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  2230
potentially infinite message streams.
wenzelm@49968
  2231
wenzelm@49968
  2232
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  2233
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  2234
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  2235
schemes.
wenzelm@49968
  2236
wenzelm@50184
  2237
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  2238
symbols.
wenzelm@50184
  2239
wenzelm@51082
  2240
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  2241
continuous display of the chart slows down the system.
wenzelm@50701
  2242
wenzelm@50183
  2243
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  2244
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  2245
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  2246
wenzelm@50198
  2247
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  2248
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  2249
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  2250
need to be adapted to local keyboard layouts.
wenzelm@50183
  2251
wenzelm@50730
  2252
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  2253
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  2254
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  2255
wenzelm@50406
  2256
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  2257
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  2258
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  2259
Isabelle distribution.
wenzelm@50406
  2260
wenzelm@49968
  2261
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  2262
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  2263
now bundled exclusively with Isabelle.

  2269
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
  2270
wenzelm@50646
  2271
* Command 'export_code': relative file names are interpreted
wenzelm@50646
  2272
relatively to master directory of current theory rather than the
wenzelm@50646
  2273
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371

wenzelm@48205
  2275
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  2276
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  2277
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  2278
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  2279
with some care where this is really required.
wenzelm@48205
  2280
wenzelm@48792
  2281
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  2282
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  2283
given sort.  Example (in HOL):
wenzelm@48792
  2284
wenzelm@48792
  2285
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792

wenzelm@50646
  2324
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
  2325

wenzelm@50646
  2326
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
  2327

  2328
INCOMPATIBILITY.
haftmann@49948
  2329
wenzelm@49836
  2330
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  2331

  2366
    expresses that when the input values x converge to F then the
wenzelm@50646
  2367
    output f x converges to G.
wenzelm@50646
  2368
wenzelm@50646
  2369
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  2370
    infinity (at_bot).
wenzelm@50646
  2371
wenzelm@50646
  2372
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  2373
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  2374
wenzelm@50646
  2375
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
  2376
    at_top".

wenzelm@50646
  2379
wenzelm@50646
  2380
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
  2381
lattice type classes.
wenzelm@50646
  2382
wenzelm@50646
  2383
* Theory "Library/Multiset": renamed
wenzelm@50646
  2384
wenzelm@50646
  2385
    constant fold_mset ~> Multiset.fold
wenzelm@50646

  2388
INCOMPATIBILITY.
wenzelm@50646
  2389
wenzelm@50646
  2390
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  2391
changes as follows.
wenzelm@50646
  2392
wenzelm@50646
  2393
  - Renamed constants (and related lemmas)
Christian@49145
  2394
Christian@49145
  2395
      prefix ~> prefixeq
Christian@49145
  2396
      strict_prefix ~> prefix
Christian@49145
  2397
wenzelm@50646
  2398
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  2399
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  2400
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  2401
    Renamed lemmas accordingly.
wenzelm@50646
  2402
wenzelm@50646
  2403
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  2404
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  2405
    "list_hembeq (op =)".
wenzelm@50646
  2406
wenzelm@50646
  2407
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  2408
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  2409
    interpretations). The type class instances are now in theory
wenzelm@50646
  2410
    Library/Prefix_Order.
wenzelm@50646
  2411
wenzelm@50646
  2412
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
  2413
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516

wenzelm@50646
  2433
wenzelm@50646
  2434
* New theory Library/Countable_Set.
wenzelm@50646

wenzelm@50646
  2436
* Theory Library/Debug and Library/Parallel provide debugging and
wenzelm@50646
  2437
parallel execution for code generated towards Isabelle/ML.
wenzelm@50646
  2438
wenzelm@50646
  2439
* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
  2440
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
  2441
extensional_funcset by an abbreviation, and renamed lemmas from
wenzelm@50646
  2442
extensional_funcset to PiE as follows:

* Theory Library/FinFun: theory of almost everywhere constant
wenzelm@50646
  2458
functions (supersedes the AFP entry "Code Generation for Functions as
wenzelm@50646
  2459
Data").
wenzelm@50646
  2460
wenzelm@50646
  2461
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
  2462
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
  2463
TYPE('a) as another parameter avoids unnecessary closures in generated
wenzelm@50646
  2464
code.
wenzelm@50646
  2465
wenzelm@50646
  2466
* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646
  2467
from sorted associative lists. Merging two trees with rbt_union may
wenzelm@50646
  2468
return a structurally different tree than before.  Potential
wenzelm@50646
  2469
INCOMPATIBILITY.
wenzelm@50646

  "basis :: 'a::euclidean_space => nat => real"
wenzelm@50646
  2478
  "\<Chi>\<Chi> :: (nat => real) => 'a::euclidean_space"
wenzelm@50646
  2479
wenzelm@50646
  2480

wenzelm@50646
  2481
vectors from the Basis set: "\<Chi>\<Chi> i. f i" is superseded by
wenzelm@50646
  2482
"SUM i : Basis. f i * r i".
wenzelm@50646
  2483
wenzelm@50646
  2484
  With this change the following constants are also changed or removed:
wenzelm@50646
  2485
wenzelm@50646
  2486
    DIM('a) :: nat  ~>  card (Basis :: 'a set)   (is an abbreviation)

  2487
    a $$ i  ~>  inner a i  (where i : Basis)
wenzelm@50646
  2488
    cart_base i  removed
wenzelm@50646
  2489
    \<pi>, \<pi>'  removed
hoelzl@50526

hoelzl@50526
  2491
  Theorems about these constants where removed.
hoelzl@50526

  2508
* HOL/Probability:
wenzelm@50646
  2509
wenzelm@50646
  2510
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
  2511
wenzelm@50646
  2512
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
  2513
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
  2514
    (borel_measurable_induct).
wenzelm@50646
  2515
wenzelm@50646
  2516
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a
wenzelm@50646
  2517
    projective family).
wenzelm@50646
  2518
wenzelm@50646

AFP entry "Ordinals_and_Cardinals").
wenzelm@50646
  2521
wenzelm@50646
  2522
* HOL/BNF: New (co)datatype package based on bounded natural functors
wenzelm@50646
  2523
with support for mixed, nested recursion and interesting non-free
wenzelm@50646
  2524
datatypes.
blanchet@48094
  2525
wenzelm@50991
  2526
* HOL/Finite_Set and Relation: added new set and relation operations
kuncar@50878
  2527
expressed by Finite_Set.fold.
kuncar@50878
  2528
kuncar@50878
  2529
* New theory HOL/Library/RBT_Set: implementation of sets by red-black
kuncar@50878
  2530
trees for the code generator.
kuncar@50878
  2531
kuncar@50878
  2532
* HOL/Library/RBT and HOL/Library/Mapping have been converted to
kuncar@50878
  2533
Lifting/Transfer.
kuncar@50878
  2534
possible INCOMPATIBILITY.
kuncar@50878

*** Document preparation ***
wenzelm@48206
  2541
wenzelm@50646
  2542
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  2543
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  2544
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  2545
wenzelm@50646
  2546
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  2547
instead of slightly exotic babel/greek.
wenzelm@48206
  2548
wenzelm@48616
  2549
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  2550
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  2551
document/root.tex.
wenzelm@48616
  2552
wenzelm@48657
  2553
* Simplified custom document/build script, instead of old-style
wenzelm@48657
  2554
document/IsaMakefile.  Minor INCOMPATIBILITY.
wenzelm@48657

wenzelm@48992
  2557
*** ML ***
wenzelm@48992
  2558
wenzelm@50646
  2559
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  2560
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  2561
hardware and Poly/ML runtime system.
wenzelm@50646
  2562
wenzelm@49869
  2563
* Type Seq.results and related operations support embedded error
wenzelm@49869
  2564
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  2565
informative errors in the absence of any usable results.
wenzelm@49869
  2566
wenzelm@48992
  2567
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  2568
formal device to inline positions into message text, but not
wenzelm@48992
  2569
necessarily printing visible text.

*** System ***
wenzelm@48206
  2573
wenzelm@48585
  2574
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  2575
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  2576
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  2577
session root directories for use with "isabelle build", similar to
wenzelm@51056
  2578
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  2579
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  2580
mkdir / make are rendered obsolete.
wenzelm@48736
  2581
wenzelm@51056
  2582
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  2583
regular isabelle build tool.  For example:
wenzelm@51056
  2584
wenzelm@51056
  2585
  isabelle build -s -b HOL
wenzelm@51056
  2586
wenzelm@48736
  2587
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  2588
wenzelm@48722
  2589
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  2590
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  2591
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  2592
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  2593
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  2594
wenzelm@48693
  2595
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  2596
required for "isabelle build", for example.
wenzelm@48693
  2597
wenzelm@50646
  2598
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  2599
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  2600
wenzelm@50646
  2601
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  2602
INCOMPATIBILITY.
wenzelm@50646
  2603
wenzelm@48844
  2604
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  2605
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  2606
version of Isabelle.
wenzelm@48844
  2607
wenzelm@50646
  2608
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
  2609
platform family: "linux", "macos", "windows".
wenzelm@50646
  2610
wenzelm@50646
  2611
* The ML system is configured as regular component, and no longer
wenzelm@50646
  2612
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  2613
for home-made settings.
wenzelm@50132
  2614
wenzelm@50701
  2615
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  2616
wenzelm@48206
  2617
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  2618
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  2619
configuration.
wenzelm@48206
  2620
wenzelm@48574
  2621
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  2622
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  2623
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  2624
settings manually, or use a Proof General version that has been
wenzelm@48574
  2625
bundled as Isabelle component.

wenzelm@47585
  2636
  - more robust Sledgehammer integration (as before the sledgehammer

  - support for user-defined Isar commands within the running session
wenzelm@47158
  2641
  - improved support for Unicode outside original 16bit range
wenzelm@47158

* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  2645
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  2646
commands to be used in the same theory where defined.
wenzelm@46485
  2647
wenzelm@47482
  2648
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  2649
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  2650
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  2651
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  2652
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  2653
wenzelm@47482
  2654
  context
wenzelm@47482
  2655
    fixes x y z :: 'a
wenzelm@47482
  2656
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  2657
  begin
wenzelm@47482
  2658
wenzelm@47482
  2659
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  2660
wenzelm@47482
  2661
  end
wenzelm@47482
  2662
wenzelm@47482
  2663
  thm my_trans
wenzelm@47482
  2664
wenzelm@47482
  2665
The most basic application is to factor-out context elements of
wenzelm@47482
  2666
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  2667
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  2668
wenzelm@47482
  2669
Any other local theory specification element works within the "context
wenzelm@47482
  2670
... begin ... end" block as well.
wenzelm@47482
  2671
wenzelm@47484
  2672
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  2673
given name in the context.  These may be later included in other
wenzelm@47484
  2674
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  2675
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  2676
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  2677
wenzelm@47829
  2678
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  2679
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  2680
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  2681
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  2682
indices of schematic variables.
wenzelm@47829
  2683
wenzelm@47829
  2684
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  2685
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  2686
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  2687
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  2688
etc. was exploited.
wenzelm@47829
  2689
wenzelm@47829
  2690
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  2691
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  2692
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  2693
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  2694
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  2695
of the material of that old tutorial.
wenzelm@47829
  2696
wenzelm@47829
  2697
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  2698
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  2699
manual.

wenzelm@46976
  2704
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  2705
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  2706
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  2707
wenzelm@47855
  2708
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  2709
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  2710
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  2711
undocumented feature.)
wenzelm@47855
  2712
wenzelm@47856
  2713
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  2714
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  2715
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  2716
wenzelm@47856
  2717
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  2718
wenzelm@47856
  2719
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  2720
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  2721
wenzelm@47856
  2722
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  2723
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  2724
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  2725
order to accommodate newly introduced premises.)
wenzelm@47856
  2726
wenzelm@47806
  2727
* Renamed some inner syntax categories:
wenzelm@47806
  2728
wenzelm@47806
  2729
    num ~> num_token
wenzelm@47806
  2730
    xnum ~> xnum_token
wenzelm@47806
  2731
    xstr ~> str_token
wenzelm@47806
  2732
wenzelm@47806
  2733
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  2734
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  2735
position information via constraints).
wenzelm@47806
  2736
wenzelm@47829
  2737
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  2738
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  2739
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  2740
wenzelm@47856
  2741
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  2742
in parse trees are always annotated by position constraints.
wenzelm@45134
  2743
wenzelm@47464
  2744
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  2745
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  2746
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  2747
wenzelm@47464
  2748
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  2749
"code_unfold" instead.  INCOMPATIBILITY.
