*** Pure ***
wenzelm@60331
    11
wenzelm@60387
    12
* Isar command 'obtain' binds term abbreviations (via 'is' patterns) in
wenzelm@60387
    13
the proof body as well, abstracted over hypothetical parameters.
wenzelm@60387
    14
wenzelm@60371
    15
* New Isar command 'supply' supports fact definitions during goal
wenzelm@60371
    16
refinement ('apply' scripts).
wenzelm@60371
    17
wenzelm@60331
    18
* Configuration option rule_insts_schematic has been discontinued
wenzelm@60331
    19
(intermediate legacy feature in Isabelle2015).  INCOMPATIBILITY.
wenzelm@60331
    20
haftmann@60347
    21
* Abbreviations in type classes now carry proper sort constraint.
haftmann@60347
    22
Rare INCOMPATIBILITY in situations where the previous misbehaviour
haftmann@60347
    23
has been exploited previously.
haftmann@60347
    24
haftmann@60347
    25
* Refinement of user-space type system in type classes: pseudo-local
haftmann@60347
    26
operations behave more similar to abbreviations.  Potential
haftmann@60347
    27
INCOMPATIBILITY in exotic situations.

    32
* Discontinued simp_legacy_precond. Potential INCOMPATIBILITY.
wenzelm@60138
    33
blanchet@60306
    34
* Sledgehammer:
blanchet@60306
    35
  - Proof reconstruction has been improved, to minimize the incidence of
blanchet@60306
    36
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
    37
  - Auto Sledgehammer now minimizes and preplays the results.
blanchet@60306
    38
blanchet@60310
    39
* Nitpick:
blanchet@60310
    40
  - Removed "check_potential" and "check_genuine" options.
blanchet@60310
    41
haftmann@60352
    42
* Constants Fields.divide (... / ...) and Divides.div (... div ...)
haftmann@60352
    43
are logically unified to Rings.divide in syntactic type class
haftmann@60352
    44
Rings.divide, with particular infix syntax added as abbreviations
haftmann@60352
    45
in classes Fields.inverse and Divides.div respectively.  INCOMPATIBILITY,
haftmann@60352
    46
instantiatios must refer to Rings.divide rather than the former
haftmann@60352
    47
separate constants, and infix syntax is usually not available during
haftmann@60352
    48
instantiation.

    54
*** General ***
wenzelm@57941
    55
wenzelm@59939
    56
* Local theory specification commands may have a 'private' or
wenzelm@59990
    57
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
    58
as provided by some "context begin ... end" block. For example:
wenzelm@59926
    59
wenzelm@59926
    60
  context
wenzelm@59926
    61
  begin
wenzelm@59926
    62
wenzelm@59926
    63
  private definition ...
wenzelm@59926
    64
  private lemma ...
wenzelm@59926
    65
wenzelm@59990
    66
  qualified definition ...
wenzelm@59990
    67
  qualified lemma ...
wenzelm@59990
    68
wenzelm@59926
    69
  lemma ...
wenzelm@59926
    70
  theorem ...
wenzelm@59926
    71
wenzelm@59926
    72
  end
wenzelm@59926
    73
wenzelm@59901
    74
* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
    75
naming policy.
wenzelm@59901
    76
wenzelm@59951
    77
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
    78
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
    79
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
    80
wenzelm@59951
    81
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
    82
together with an attribute to maintain the content incrementally. This
wenzelm@59951
    83
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
    84
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
    85
wenzelm@59951
    86
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
    87
schematically expanded before search. Search results match the naive
wenzelm@59951
    88
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
    89
INCOMPATIBILITY.
wenzelm@59648
    90
wenzelm@59569
    91
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
    92
theory context.
wenzelm@57941
    93
wenzelm@58928
    94
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
    95
context, without implicit global state. Potential for accidental
wenzelm@58928
    96
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
    97
wenzelm@60115
    98
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60115
    99
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60115
   100
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60115
   101
sources.
wenzelm@60115
   102
wenzelm@59951
   103
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
   104
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
   105
wenzelm@60119
   106
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   107
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   108
method provides basic fact/term matching in addition to
wenzelm@60119
   109
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   110
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
   111
documentation provides an entry "eisbach" for the Eisbach User Manual.
wenzelm@60288
   112
Sources and various examples are in ~~/src/HOL/Eisbach/.

   115
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@58524
   116
wenzelm@59569
   117
* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
   118
the "sidekick" mode may be used for document structure.
wenzelm@59569
   119
wenzelm@59569
   120
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
   121
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
   122
in the buffer.
wenzelm@58758
   123
wenzelm@58540
   124
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
   125
marker, SideKick parser.
wenzelm@58524
   126
wenzelm@58551
   127
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   128
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   129
the editor (hyperlinks, completion etc.).
wenzelm@58551
   130
wenzelm@58785
   131
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   132
Options / Text Area).
wenzelm@58785
   133
wenzelm@60089
   134
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   135
display of 'thy_deps', 'class_deps' etc.
wenzelm@60009
   136
wenzelm@60115
   137
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60115
   138
restrict the visualized hierarchy.
wenzelm@60093
   139
wenzelm@60072
   140
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
   141
managed by the Sledgehammer panel) wrt. ongoing document processing.
wenzelm@60072
   142
wenzelm@58524
   143
wenzelm@59951
   144
*** Document preparation ***
wenzelm@59951
   145
wenzelm@59951
   146
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   147
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   148
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   149
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   150
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   151
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   152
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   153
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   154
wenzelm@60009
   155
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60009
   156
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60009
   157
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60009
   158
as argument to other macros (such as footnotes).
wenzelm@60009
   159
wenzelm@60009
   160
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60009
   161
style.
wenzelm@60009
   162
wenzelm@60009
   163
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60009
   164
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60009
   165
wenzelm@59951
   166
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   167
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   168
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   169
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   170
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   171
wenzelm@59951
   172
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   173
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   174
Only the margin for document output may be changed, but not the global
wenzelm@59951
   175
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   176
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   177
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   178
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   179
wenzelm@60299
   180
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   181
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
   182
copying of the document/ directory is no longer supported. Minor
wenzelm@60299
   183
INCOMPATIBILITY.
wenzelm@60299
   184
wenzelm@59951
   185
haftmann@58202
   186
*** Pure ***
haftmann@58202
   187
wenzelm@59835
   188
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   189
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   190
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   191
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   192
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   193
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   194
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   195
variable declarations or dummy patterns instead.
wenzelm@59835
   196
wenzelm@60009
   197
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60009
   198
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60009
   199
("_") that stand for anonymous local variables.
wenzelm@60009
   200
wenzelm@59951
   201
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   202
incremented to avoid material in the proof context. Rare
wenzelm@59951
   203
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   204
different index.
wenzelm@59951
   205
wenzelm@60010
   206
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60010
   207
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60010
   208
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60010
   209
like "(- 1) ^ n".
haftmann@58410
   210
wenzelm@58421
   211
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
   212
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
   213
token category instead.
wenzelm@58421

*** HOL ***
blanchet@57737
   217
blanchet@57983
   218
* New (co)datatype package:
blanchet@58373
   219
  - The 'datatype_new' command has been renamed 'datatype'. The old
blanchet@58373
   220
    command of that name is now called 'old_datatype' and is provided
blanchet@58373
   221
    by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58373
   222
    'isabelle doc datatypes' for information on porting.
blanchet@58373
   223
    INCOMPATIBILITY.
blanchet@57983
   224
  - Renamed theorems:
blanchet@57983
   225
      disc_corec ~> corec_disc
blanchet@57983
   226
      disc_corec_iff ~> corec_disc_iff
blanchet@57983
   227
      disc_exclude ~> distinct_disc
blanchet@57983
   228
      disc_exhaust ~> exhaust_disc
blanchet@57983
   229
      disc_map_iff ~> map_disc_iff
blanchet@57983
   230
      sel_corec ~> corec_sel
blanchet@57983
   231
      sel_exhaust ~> exhaust_sel
blanchet@57983
   232
      sel_map ~> map_sel
blanchet@57983
   233
      sel_set ~> set_sel
blanchet@57983
   234
      sel_split ~> split_sel
blanchet@57983
   235
      sel_split_asm ~> split_sel_asm
blanchet@57983
   236
      strong_coinduct ~> coinduct_strong
blanchet@57983
   237
      weak_case_cong ~> case_cong_weak
blanchet@57983
   238
    INCOMPATIBILITY.
blanchet@58192
   239
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192
   240
    "codatatype" has been renamed "plugins del: code".
blanchet@58192
   241
    INCOMPATIBILITY.
blanchet@58044
   242
  - The rules "set_empty" have been removed. They are easy
blanchet@58044
   243
    consequences of other set rules "by auto".
blanchet@58044
   244
    INCOMPATIBILITY.
blanchet@58044
   245
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
   246
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
   247
    method when more than one case rule is applicable (e.g., an
blanchet@57990
   248
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   249
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
   250
    (e.g. "cases w rule: widget.exhaust").
blanchet@57990
   251
    INCOMPATIBILITY.
blanchet@59675
   252
  - Renamed theories:
blanchet@59675
   253
      BNF_Comp ~> BNF_Composition
blanchet@59675
   254
      BNF_FP_Base ~> BNF_Fixpoint_Base
blanchet@59675
   255
      BNF_GFP ~> BNF_Greatest_Fixpoint
blanchet@59675
   256
      BNF_LFP ~> BNF_Least_Fixpoint
blanchet@59675
   257
      BNF_Constructions_on_Wellorders ~> BNF_Wellorder_Constructions
blanchet@59675
   258
      Cardinals/Constructions_on_Wellorders ~> Cardinals/Wellorder_Constructions
blanchet@59675
   259
    INCOMPATIBILITY.
wenzelm@60114
   260
  - Lifting and Transfer setup for basic HOL types sum and prod (also
wenzelm@60114
   261
    option) is now performed by the BNF package. Theories Lifting_Sum,
wenzelm@60114
   262
    Lifting_Product and Lifting_Option from Main became obsolete and
wenzelm@60114
   263
    were removed. Changed definitions of the relators rel_prod and
wenzelm@60114
   264
    rel_sum (using inductive).
traytel@60111
   265
    INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead
wenzelm@60114
   266
    of rel_prod_def and rel_sum_def.
wenzelm@60114
   267
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60114
   268
    changed (e.g. map_prod_transfer ~> prod.map_transfer).
wenzelm@60261
   269
  - Parametricity theorems for map functions, relators, set functions,
wenzelm@60261
   270
    constructors, case combinators, discriminators, selectors and

blanchet@59039
   287
* Nitpick:
wenzelm@60010
   288
  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   289
    operations.
blanchet@59039
   290
blanchet@57737
   291
* Sledgehammer:
blanchet@59511
   292
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   293
    default.
blanchet@59965
   294
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   295
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
   296
  - Minimization is now always enabled by default.
wenzelm@60010
   297
    Removed sub-command:
blanchet@57737
   298
      min
blanchet@59967
   299
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039
   300
    dramatically improved.
blanchet@59039
   301
  - Improved support for CVC4 and veriT.
blanchet@57737
   302
blanchet@58062
   303
* Old and new SMT modules:
blanchet@58067
   304
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   305
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   306
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   307
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   308
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
   309
    point to it.
blanchet@58062
   310
    INCOMPATIBILITY.

boehmes@59216
   315
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
   316
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060

* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
   319
that have as a return type a datatype containing a subtype. This
wenzelm@60261
   320
overcomes long-time limitations in the area of code generation and
wenzelm@60261
   321
lifting, and avoids tedious workarounds.
kuncar@60258
   322
wenzelm@60009
   323
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60009
   324
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60009
   325
Minor INCOMPATIBILITY.

* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60009
   328
wenzelm@60009
   329
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60009
   330
non-termination in case of distributing a division. With this change
wenzelm@60009
   331
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60009
   332
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60009
   333
wenzelm@60009
   334
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60009
   335
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60009

"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60009
   342
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60009

   345
additive inverse operation. INCOMPATIBILITY.
wenzelm@60009
   346
lp15@60020
   347
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
   348
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
   349
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
   350
wenzelm@60009
   351

wenzelm@60009
   352
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60009
   353
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60009
   354
needed.
wenzelm@60009
   355
wenzelm@60009
   356
* New library of properties of the complex transcendental functions sin,
wenzelm@60009
   357
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60009
   358
wenzelm@60009
   359
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60009
   360
that admits numeric types including nat, int, real and complex.
wenzelm@60009
   361
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60009
   362
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60009
   363
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60009
   364
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60009
   365
wenzelm@60009
   366
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60009
   367
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60009
   368
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60009
   369
"nat_floor"/"nat_ceiling".
wenzelm@60009
   370
wenzelm@60009
   371
* Qualified some duplicated fact names required for boostrapping the

   377
Minor INCOMPATIBILITY.
wenzelm@60009
   378
wenzelm@60009

  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60009
   381
  mult_less_imp_less_left ~> mult_left_less_imp_less

   382
Minor INCOMPATIBILITY.
wenzelm@60009
   383
wenzelm@60009
   384
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60009
   385
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60009
   386
wenzelm@60009
   387
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60009

   389
  dvd_plus_eq_right ~> dvd_add_right_iff

   394
and part of theory Main.
wenzelm@60009
   395
  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60009
   396
INCOMPATIBILITY.
wenzelm@60009
   397
wenzelm@60009

wenzelm@60009
   399
INCOMPATIBILITY.
wenzelm@60009
   400
wenzelm@60009
   401
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60009
   402
Fact rename:
wenzelm@60009
   403
    listsum_def ~> listsum.eq_foldr

   404
INCOMPATIBILITY.
wenzelm@60009
   405
wenzelm@60009
   406
* Product over lists via constant "listprod".
wenzelm@60009
   407
wenzelm@60009
   408
* Theory List: renamed drop_Suc_conv_tl and nth_drop' to

   409
Cons_nth_drop_Suc.
nipkow@58247

* New infrastructure for compiling, running, evaluating and testing
wenzelm@59569
   412
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
   413

   414
wenzelm@60009
   415
* Library/Multiset:
blanchet@59813
   416
  - Introduced "replicate_mset" operation.
blanchet@59813
   417
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
   418
    "Library/Multiset_Order".
blanchet@59958
   419
  - Renamed multiset ordering:

   426
      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
   427
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986
   428
    INCOMPATIBILITY.
blanchet@59813
   429
  - Renamed

* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60009
   447
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60009
   448
The "sos_cert" functionality is invoked as "sos" with additional

   449
argument. Minor INCOMPATIBILITY.
wenzelm@60009

wenzelm@60009
   451
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60009
   452
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60009
   453
hardware floating point arithmetic to randomly discover potential
wenzelm@60010
   454
counterexamples. Counterexamples are certified with the "approximation"
wenzelm@60009

* HOL-Probability: Reworked measurability prover
wenzelm@60010
   459
  - applies destructor rules repeatedly
hoelzl@59354
   460
  - removed application splitting (replaced by destructor rule)
wenzelm@59569
   461
  - added congruence rules to rewrite measure spaces under the sets

*** ML ***
blanchet@58066

wenzelm@60009
   470
* Subtle change of name space policy: undeclared entries are now
wenzelm@60009
   471
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60009
   472
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60009
   473
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60010
   474
contemporary applications use the strict Name_Space.check (and
wenzelm@60009
   475

wenzelm@60009
   476
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951

ERROR instead of internal Toplevel.UNDEF.
wenzelm@60094
   480
wenzelm@59951

as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951

wenzelm@59951
   489
Multithreading.synchronized and its high-level derivative
wenzelm@59951
   490
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951

   495
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899

wenzelm@59621
   497
* The main operations to certify logical entities are Thm.ctyp_of and

pool, like Isabelle system option "threads" for ML.
wenzelm@59200
   539
wenzelm@59201

wenzelm@54055
   551
wenzelm@54702
   552
*** General ***
wenzelm@54702
   553
wenzelm@57452
   554
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
   555
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
   556
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
   557
environment is restricted to the Standard ML implementation of
wenzelm@57452
   558
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
   559
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
   560
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
   561
some examples.
wenzelm@56499
   562
wenzelm@57504
   563
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
   564
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
   565
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
   566
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   567
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   568
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   569
induction is done after these methods or when the names of free and
wenzelm@57504
   570
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   571
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   572
wenzelm@56232
   573
* More static checking of proof methods, which allows the system to
wenzelm@56232
   574
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
   575
processed in the original proof context as far as possible, before
wenzelm@56232
   576
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   577
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   578
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   579
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   580
proof tools.
wenzelm@56232
   581
wenzelm@57452
   582
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   583
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   584
supports input via ` (backquote).
wenzelm@57452
   585
wenzelm@57452
   586
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   587
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   588
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   589
wenzelm@57452
   590
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   591
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   592
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   593
Minor INCOMPATIBILITY.
wenzelm@57452
   594
wenzelm@57452
   595
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   596
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   597
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   598
INCOMPATIBILITY.
wenzelm@57452
   599
wenzelm@57452
   600
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   601
which results in an active hyperlink within the text.
wenzelm@57452
   602
wenzelm@57452
   603
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   604
not check existence within the file-system.
wenzelm@57452
   605
wenzelm@57452
   606
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   607
isar-ref, jedit, system.
wenzelm@57423

   610
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   611
wenzelm@57650
   612
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   613
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   614
buffer.
wenzelm@57452
   615
wenzelm@57452
   616
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   617
to PIDE hyperlinks.
wenzelm@57452
   618
wenzelm@57452
   619
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   620
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   621
wenzelm@57452
   622
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   623
auxiliary ML files.
wenzelm@57423
   624
wenzelm@57423
   625
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   626
templates, completion language context, name-space completion,
wenzelm@57423
   627
file-name completion, spell-checker completion.
wenzelm@57423
   628
wenzelm@57423
   629
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   630
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   631
keystrokes with slow / remote graphics displays.
wenzelm@57423
   632
wenzelm@57833
   633
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   634
item, depending on Isabelle options.
wenzelm@57833
   635
wenzelm@57423
   636
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   637
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   638
caret".
wenzelm@56342
   639
wenzelm@56580
   640
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   641
completion popup and context-menu.
wenzelm@56554
   642
wenzelm@56879
   643
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   644
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   645
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   646
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   647
wenzelm@56901
   648
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   649
to highlight text via regular expression.
wenzelm@56901
   650
wenzelm@54881
   651
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   652
General") allows to specify additional print modes for the prover
wenzelm@54881
   653
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   654
"isabelle jedit -m MODE".
wenzelm@54881
   655
wenzelm@56505
   656
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   657
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   658
wenzelm@57822
   659
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   660
imports) are automatically removed from the document model.
wenzelm@57822
   661
wenzelm@57869
   662
* Improved monitor panel.
wenzelm@57869
   663
wenzelm@56838
   664
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   665
more robust treatment of threads and interrupts.
wenzelm@56838
   666
wenzelm@56939
   667
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   668
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   669
"Detach" a copy where this makes sense.
wenzelm@56939
   670
wenzelm@57452
   671
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
   672
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
   673
within the context.

*** Pure ***
wenzelm@55001
   677
wenzelm@57504
   678
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
   679
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
   680
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
   681
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
   682
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
   683
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
   684
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
   685
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
   686
Axclass.arity_axiomatization.
wenzelm@57504
   687
wenzelm@56245
   688
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   689
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   690
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   691
renaming needs to be applied:
wenzelm@56245
   692
wenzelm@56245
   693
  ==             ~>  Pure.eq
wenzelm@56245
   694
  ==>            ~>  Pure.imp
wenzelm@56245
   695
  all            ~>  Pure.all
wenzelm@56245
   696
  TYPE           ~>  Pure.type
wenzelm@56245
   697
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   698
wenzelm@56245
   699
Systematic porting works by using the following theory setup on a
wenzelm@56245
   700
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   701
old constants:
wenzelm@56245
   702
wenzelm@56245
   703
setup {*
wenzelm@56245
   704
  fn thy => thy
wenzelm@56245
   705
    |> Sign.root_path
wenzelm@56245
   706
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   707
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   708
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   709
    |> Sign.restore_naming thy
wenzelm@56245
   710
*}
wenzelm@56245
   711
wenzelm@56245
   712
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   713
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   714
the auxiliary aliases are deleted.
wenzelm@56245
   715
wenzelm@55143
   716
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   717
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   718
instantiated theorem.
wenzelm@55143
   719
wenzelm@55152
   720
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
   721
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
   722
where instantiations with schematic variables are intended (for
wenzelm@55152
   723
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
   724
following temporary definition may help to port old applications:
wenzelm@55152
   725
wenzelm@55152
   726
  attribute_setup standard =
wenzelm@55152
   727
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
   728
wenzelm@55001
   729
* More thorough check of proof context for goal statements and
wenzelm@55006
   730
attributed fact expressions (concerning background theory, declared
wenzelm@55006
   731
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
   732
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
   733
primitive Thm.assume_hyps.
wenzelm@55001
   734
wenzelm@55108
   735
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
   736
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
   737
differently, e.g. via cartouches).
wenzelm@57452
   738
wenzelm@57504
   739
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
   740
but the latter is retained some time as Proof General legacy.
wenzelm@57504
   741
wenzelm@57452
   742
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
   743
per-constant basis.  See attribute "code_preproc".

INCOMPATIBILITY.
wenzelm@57504
   756
wenzelm@57504
   757
* Code generation for SML and OCaml: dropped arcane "no_signatures"

wenzelm@57504
   759
wenzelm@57504

wenzelm@57452

wenzelm@57452
   771
wenzelm@57504

* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
   773
wenzelm@57504
   774
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504
   775
to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504
   776
wenzelm@57504

wenzelm@57452
   779
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
   780
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
   781
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
   782
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
   783
again in the future.  INCOMPATIBILITY.
nipkow@56073

wenzelm@55139
   785
* Simproc "finite_Collect" is no longer enabled by default, due to

wenzelm@57452
   831
  - Command 'primcorec' is fully implemented.
wenzelm@57452
   832
  - Command 'datatype_new' generates size functions ("size_xxx" and

wenzelm@57508
   937
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
   938
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
   939
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
   940
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
   941
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
   942
corresponding tactics; the old default can be restored using "declare
wenzelm@57508
   943
[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508
   944
wenzelm@57508
   945
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
   946
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
   947
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
   948
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
   949
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
   950
wenzelm@57508
   951
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
   952
(without requiring restart), instead of former settings variable
wenzelm@57508
   953
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

* Sledgehammer:
wenzelm@57508
   957
  - Z3 can now produce Isar proofs.
wenzelm@57508
   958
  - MaSh overhaul:
blanchet@57532
   959
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
   960
      Python and increase performance and reliability.
wenzelm@57508
   961
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
   962
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
   963
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
   964
      Options / Isabelle / General to "none".
wenzelm@57508
   965
  - New option:
wenzelm@57508
   966
      smt_proofs
wenzelm@57508
   967
  - Renamed options:
wenzelm@57508

   971
INCOMPATIBILITY.
wenzelm@57508
   972
wenzelm@57508
   973
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
   974
wenzelm@57508
   975
* Nitpick:
wenzelm@57508
   976
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
   977
    take infinite values.
wenzelm@57508
   978
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
   979
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
   980
  - Removed "std" option.
wenzelm@57508
   981
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
   982
    "hide_types".
wenzelm@57508
   983
wenzelm@57508
   984
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
   985
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
   986
wenzelm@57508
   987
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
   988
wenzelm@57508
   989
* Adjustion of INF and SUP operations:
wenzelm@57508
   990
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
   991
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
   992
    SUP instead uniformly.
wenzelm@57508
   993
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
   994
    or SUP and Sup.
wenzelm@57508
   995
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
   996
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
   997
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
   998
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508
   999
    INT_cong, SUP_cong

* SUP and INF generalized to conditionally_complete_lattice.
wenzelm@57508
  1004
wenzelm@57508
  1005
* Swapped orientation of facts image_comp and vimage_comp:

wenzelm@57504
  1543
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  1544
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  1545
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  1546
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  1547
appropriate than Thm.eq_thm.
wenzelm@57504
  1548
wenzelm@57504
  1549
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504
  1550
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  1551
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  1552
actually belongs to it).
wenzelm@57504
  1553
wenzelm@57504
  1554
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  1555
variables that are meant to become schematic need to be given as
wenzelm@57504
  1556
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  1557
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  1558
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  1559
of schematic variables.
wenzelm@57504
  1560
wenzelm@56303
  1561
* Moved ML_Compiler.exn_trace and other operations on exceptions to
wenzelm@56303
  1562
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  1563
wenzelm@56279
  1564
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  1565
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  1566
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  1567
wenzelm@56281
  1568
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  1569
INCOMPATIBILITY.
wenzelm@56281
  1570
wenzelm@56281
  1571
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  1572
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  1573
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  1574
INCOMPATIBILITY.
wenzelm@56279
  1575
wenzelm@54449
  1576
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  1577
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  1578
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  1579
formal context.
wenzelm@54449
  1580
wenzelm@56205
  1581
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  1582
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  1583
wenzelm@56071
  1584
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  1585
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  1586
wenzelm@56135
  1587
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  1588
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1589
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1590
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  1591
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  1592
wenzelm@56399
  1593
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  1594
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  1595
purposes.

* Proof General with its traditional helper scripts is now an optional
wenzelm@57504
  1601
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  1602
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  1603
the "system" manual provides general explanations about add-on
wenzelm@57504
  1604
components, especially those that are not bundled with the release.
wenzelm@57443
  1605
wenzelm@56439
  1606
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  1607
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  1608
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  1609
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  1610
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  1611
settings variable.
wenzelm@56439
  1612
wenzelm@57439
  1613
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1614
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1615
obsolete Isar TTY loop.
wenzelm@57439
  1616
wenzelm@57452
  1617
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1618
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1619
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1620
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1621
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1622
wenzelm@57413
  1623
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1624
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1625
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1626
wenzelm@57452
  1627
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1628
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1629
wenzelm@57452
  1630
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1631
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1632
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1633
wenzelm@57452
  1634
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1635
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1636
files are copied to the document output directory, before document
wenzelm@57452
  1637
processing is started.
wenzelm@57452
  1638
wenzelm@57504
  1639
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  1640
of TeX Live from Cygwin.

wenzelm@54639
  1648
wenzelm@54639
  1649
* More robust editing of running commands with internal forks,
wenzelm@54639
  1650
e.g. non-terminating 'by' steps.
wenzelm@54639
  1651
wenzelm@54641
  1652
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
  1653
after edits surrounding the command location.
wenzelm@54641
  1654
wenzelm@54648
  1655
* More status information about commands that are interrupted
wenzelm@54648

accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
  1657
e.g. out-of-memory).

wenzelm@51293
  1676
*** General ***
wenzelm@51293
  1677
wenzelm@53971
  1678
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  1679
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  1680
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  1681
wenzelm@53971
  1682
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
  1683
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1684
wenzelm@53016
  1685
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1686
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1687
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1688
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  1689
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1690
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  1691
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1692
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  1693
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  1694
syntax.
wenzelm@53016
  1695
wenzelm@53021
  1696
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  1697
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  1698
wenzelm@52487
  1699
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1700
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1701
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1702
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1703
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1704
wenzelm@52060
  1705
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  1706
INCOMPATIBILITY.
wenzelm@52060
  1707
wenzelm@52430
  1708
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1709
implicit change of some global references) is retained for now as
wenzelm@52430
  1710
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1711
wenzelm@52549
  1712
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1713
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1714
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1715
wenzelm@53971
  1716
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
  1717
eliminated old "ref" manual.

wenzelm@53852
  1723
Documentation panel.
wenzelm@53852
  1724
wenzelm@53971
  1725
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  1726
documentation.
wenzelm@52646
  1727
wenzelm@52949
  1728
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  1729
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  1730
wenzelm@53050
  1731
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  1732
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  1733
normal editing and checking process.
wenzelm@53050
  1734
wenzelm@51533
  1735
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  1736
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  1737
same timing information is shown in the extended tooltip of the
wenzelm@54332
  1738
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  1739
COMMAND modifier is pressed.
wenzelm@51533
  1740
wenzelm@53971
  1741
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  1742
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  1743
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  1744
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  1745
or shortcut "C+e SPACE".
wenzelm@53971
  1746
wenzelm@54305
  1747
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  1748
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  1749
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  1750
wenzelm@54319
  1751
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  1752
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  1753
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  1754
to resolve conflict.
wenzelm@54319
  1755
wenzelm@54305
  1756
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  1757
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  1758
wenzelm@53971
  1759
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  1760
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  1761
such command executions while editing.
wenzelm@53271
  1762
wenzelm@53971
  1763
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  1764
document content.
wenzelm@53971
  1765
wenzelm@53971
  1766
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  1767
toplevel theorem statements.
wenzelm@53971
  1768
wenzelm@53971
  1769
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  1770
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  1771
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  1772
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  1773
wenzelm@53971
  1774
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  1775
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  1776
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  1777
wenzelm@53971
  1778
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  1779
/ Global Options / Appearance".
wenzelm@53971
  1780
wenzelm@53971

ballarin@54049
  1787
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  1788
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  1789
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  1790
light-weight alternative to 'sublocale'.  See "isar-ref" manual for

ballarin@51565
  1794
wenzelm@51313
  1795
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  1796

instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  1798
wenzelm@51316
  1799
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  1800
INCOMPATIBILITY.
wenzelm@51316
  1801
wenzelm@53971
  1802
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  1803
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  1804
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  1805
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  1806
wenzelm@53971
  1807
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971

on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  1809
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  1810
wenzelm@53971
  1811
* Former global reference trace_unify_fail is now available as

  1812
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  1813
wenzelm@52463

wenzelm@54032
  1821
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  1822
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  1823
INCOMPATIBILITY.
wenzelm@54032
  1824
wenzelm@54032
  1825
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  1826
wenzelm@54032
  1827
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  1828
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  1829
from the datatype package. The declaration attribute
wenzelm@54032
  1830
"case_translation" can be used to register new case combinators:
wenzelm@54032
  1831
wenzelm@54032
  1832
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  1833
haftmann@52435
  1834
* Code generator:
wenzelm@53160
  1835
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  1836
    'code_instance'.
wenzelm@53160
  1837
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  1838
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  1839
wenzelm@53983
  1840
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  1841
examples.
haftmann@52435
  1842
wenzelm@54032
  1843
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  1844
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  1845
to distinguish both when desired.
wenzelm@54032
  1846
wenzelm@54032
  1847
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  1848
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  1849
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
  1850
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  1851
wenzelm@54032
  1852
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  1853
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  1854
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  1855
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  1856
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  1857
ML).  INCOMPATIBILITY.
wenzelm@54032
  1858
wenzelm@54032
  1859
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  1860
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  1861
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  1862
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  1863
wenzelm@54032
  1864
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  1865
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  1866
wenzelm@54032
  1867
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  1868
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  1869
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
  1870
kuncar@54021
  1871
* Lifting:
kuncar@54021
  1872
  - parametrized correspondence relations are now supported:
wenzelm@54378
  1873
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  1874
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  1875
      transfer rules
kuncar@54021
  1876
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  1877
      correspondence relation can be generated
kuncar@54021
  1878
    + various new properties of the relator must be specified to support
kuncar@54021
  1879
      parametricity
kuncar@54021
  1880
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  1881
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  1882
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  1883
    copies
kuncar@54021
  1884
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  1885
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  1886
    anonymous context)
wenzelm@54378
  1887
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  1888
    Main. Potential INCOMPATIBILITY
kuncar@54021
  1889
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  1890
    lifting_forget, lifting_update
wenzelm@54378
  1891
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  1892
    INCOMPATIBILITY
kuncar@54021
  1893
kuncar@54021
  1894
* Transfer:
wenzelm@54378
  1895
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  1896
    by the actual invariant in a transferred goal
kuncar@54021
  1897
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  1898
  - Experimental support for transferring from the raw level to the
kuncar@54021
  1899
    abstract level: Transfer.transferred attribute
kuncar@54021
  1900
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  1901
haftmann@52286
  1902
* Reification and reflection:
wenzelm@53160
  1903
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  1904
    "Reification".
wenzelm@53160
  1905
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  1906
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  1907
INCOMPATIBILITY.
haftmann@52286
  1908
haftmann@51489
  1909
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  1910
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  1911
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  1912
    This is now identity on infinite sets.
wenzelm@52745
  1913
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  1914
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  1915
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  1916
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  1917
    See theory Big_Operators for canonical examples.
haftmann@51489
  1918
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  1919
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  1920
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  1921
    those foundational constants as substitutes, but it is
wenzelm@53983
  1922
    preferable to interpret the above locales accordingly.
haftmann@51489
  1923
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  1924
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  1925
  - Fact renames:
haftmann@51489
  1926
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  1927
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  1928
INCOMPATIBILITY.
haftmann@51489
  1929
haftmann@51487
  1930
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  1931
wenzelm@53526
  1932
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  1933
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  1934
class predicate assumption or sort constraint when possible.
Andreas@53362
  1935
INCOMPATIBILITY.
Andreas@53362
  1936
wenzelm@53160
  1937
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  1938
complete lattice but does not assume the existence of the top and
wenzelm@53160
  1939
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  1940
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  1941
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  1942
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  1943
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  1944
lemmas.
wenzelm@53160
  1945
wenzelm@53160
  1946
* Introduce type class linear_continuum as combination of
wenzelm@53160
  1947
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  1948
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  1949
wenzelm@53983
  1950
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  1951
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  1952
Rename bot -> order_bot, top -> order_top
lammich@53683
  1953
wenzelm@53160
  1954
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  1955
top and bottom elements.
hoelzl@51732
  1956
hoelzl@51732
  1957
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  1958
hoelzl@51732
  1959
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  1960
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  1961
wenzelm@53983
  1962
 - Introduce type class (lin)order_topology and
wenzelm@53983
  1963
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  1964
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  1965
hoelzl@51732
  1966
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  1967
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  1968
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  1969
wenzelm@53983
  1970
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  1971
   arbitrary filter.
wenzelm@53983
  1972
wenzelm@53983
  1973
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  1974
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  1975
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  1976
   continuous function is continuous, when the function is continuous
wenzelm@53983
  1977
   on a compact set.
hoelzl@51732
  1978
hoelzl@51732
  1979
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  1980
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  1981
   linear_continuum_topology).
hoelzl@51732
  1982
hoelzl@51732
  1983
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  1984
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  1985
   on all sequences converging to x.
wenzelm@53983
  1986
wenzelm@53983
  1987
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  1988
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  1989
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  1990
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  1991
   left or right.
hoelzl@51732
  1992
hoelzl@51732
  1993
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  1994
hoelzl@51732
  1995
     F within X = inf F (principal X)
hoelzl@51732
  1996
hoelzl@51732
  1997
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  1998
   abbreviation for "at x within UNIV"
hoelzl@51732
  1999
wenzelm@53983
  2000
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  2001
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  2002
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  2003
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  2004
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  2005
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  2006
hoelzl@51732
  2007
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  2008
hoelzl@51732
  2009
   + Moved RealDef and RComplete into Real
hoelzl@51732
  2010
hoelzl@51732
  2011
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  2012
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  2013
hoelzl@51732
  2014
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  2015
wenzelm@53983
  2016
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  2017
     Real_Vector_Spaces, and Limits
hoelzl@51732
  2018
hoelzl@51732
  2019
   + Moved Ln and Log to Transcendental
hoelzl@51732
  2020
hoelzl@51732
  2021
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  2022
hoelzl@51732
  2023
 - Remove various auxiliary lemmas.

blanchet@55889
  2036
  - Better support for "isar_proofs".
blanchet@55889
  2037
  - MaSh has been fined-tuned and now runs as a local server.
blanchet@51137
  2038
wenzelm@54032
  2039
* Improved support for ad hoc overloading of constants (see also

wenzelm@54032
  2041
wenzelm@54032
  2042
* Library/Polynomial.thy:
wenzelm@54032
  2043
  - Use lifting for primitive definitions.
wenzelm@54032
  2044
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
  2045
    generated code.
wenzelm@54032
  2046
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
  2047
  - Prefer pre-existing gcd operation for gcd.
wenzelm@54032
  2048
  - Fact renames:

IMCOMPATIBILITY.
wenzelm@54032
  2053
wenzelm@54032
  2054
* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
wenzelm@54032
  2055
case_of_simps to convert function definitions between a list of
wenzelm@54032
  2056
equations with patterns on the lhs and a single equation with case

expressions on the rhs. See also Ex/Simps_Case_Conv_Examples.thy.
wenzelm@54032
  2058

  2060
sets defined by Lifting/Transfer.
wenzelm@54032
  2061
wenzelm@54032

* Discontinued theory src/HOL/Library/Eval_Witness.  INCOMPATIBILITY.
wenzelm@54032
  2063
wenzelm@54032

  2075
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
  2076
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983

* HOL-BNF:
wenzelm@54032
  2081
  - Various improvements to BNF-based (co)datatype package, including

* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  2104
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
  2105
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its

wenzelm@53971
  2107
wenzelm@53709
  2108
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709
  2109
tracing output in the command transaction context instead of physical
wenzelm@53709
  2110

* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
  2114
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
  2115

  2117
INCOMPATIBILITY.
wenzelm@53164
  2118
wenzelm@51551

wenzelm@51551
  2121
    Skip_Proof.prove  ~>  Goal.prove_sorry

  2124
Minor INCOMPATIBILITY.
wenzelm@51703
  2125
wenzelm@51717
  2126
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
  2127
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
  2128
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
  2129
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
  2130
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
  2131
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
  2132
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
  2133
wenzelm@53971
  2134
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  2135
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
  2136
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
  2137
clasets separately from the context.
wenzelm@53971
  2138
wenzelm@51717
  2139
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.

wenzelm@51717
  2141

wenzelm@52439
  2167
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
  2168
keyword tables): use Isabelle/Scala operations, which inspect outer

wenzelm@52439
  2170
wenzelm@53971
  2171
* Sessions may be organized via 'chapter' specifications in the ROOT

wenzelm@53971
  2174
tendency towards erratic fluctuation of URLs) has been discontinued.

*** General ***
wenzelm@47967
  2184
wenzelm@50126
  2185
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  2186
no longer printed by default, since it is incompatible with
wenzelm@50126
  2187
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  2188
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  2189
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  2190
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  2191
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  2192
wenzelm@49699
  2193
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  2194
into the printed representation of formal entities --- notably type
wenzelm@49699
  2195
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  2196
information via tooltips in the output window, for example.
wenzelm@49699
  2197
wenzelm@48890
  2198
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  2199
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  2200
wenzelm@49243
  2201
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  2202
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  2203
Tools that load their additional source files may imitate the
wenzelm@49243
  2204
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  2205
dependencies properly.
wenzelm@49243
  2206
wenzelm@47967
  2207
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  2208
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  2209
wenzelm@50110
  2210
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  2211
remaining material in old "ref" manual.
wenzelm@48120
  2212
wenzelm@51050
  2213
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  2214
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  2215
and "class ... context ...".
wenzelm@49841
  2216
wenzelm@50772
  2217
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  2218
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  2219
the target context.  This form of declaration is stable when exported
wenzelm@50772
  2220
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  2221
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  2222
in HOL/inductive and HOL/function.
wenzelm@50772
  2223
wenzelm@49869
  2224
* More informative error messages for Isar proof commands involving
wenzelm@49869
  2225
lazy enumerations (method applications etc.).
wenzelm@49869
  2226
wenzelm@50213
  2227
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  2228
to name patterns (with clickable results).

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  2232
wenzelm@49968
  2233
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  2234
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  2235
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  2236
surface, while the prover is still crunching on internal
wenzelm@49968
  2237
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  2238
required to complete full proof checking eventually.
wenzelm@49968
  2239
wenzelm@49968
  2240
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  2241
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  2242
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  2243
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  2244
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  2245
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  2246
wenzelm@50717
  2247
* Improved support for commands that produce graph output: the text
wenzelm@50717
  2248
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  2249
browser on demand.
wenzelm@50717
  2250
wenzelm@49968
  2251
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  2252
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  2253
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  2254
that frequently occur in user interaction.
wenzelm@49968
  2255
wenzelm@49968
  2256
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  2257
files.  More scalable management of formal document content.
wenzelm@49968
  2258
wenzelm@50505
  2259
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  2260
certain number of messages per command transaction, with some user
wenzelm@50505
  2261
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  2262
potentially infinite message streams.
wenzelm@49968
  2263
wenzelm@49968
  2264
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  2265
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  2266
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  2267
schemes.
wenzelm@49968
  2268
wenzelm@50184
  2269
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  2270
symbols.
wenzelm@50184
  2271
wenzelm@51082
  2272
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  2273
continuous display of the chart slows down the system.
wenzelm@50701
  2274
wenzelm@50183
  2275
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  2276
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  2277
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  2278
wenzelm@50198
  2279
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  2280
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  2281
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  2282
need to be adapted to local keyboard layouts.
wenzelm@50183
  2283
wenzelm@50730
  2284
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  2285
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  2286
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  2287
wenzelm@50406
  2288
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  2289
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  2290
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  2291
Isabelle distribution.
wenzelm@50406
  2292
wenzelm@49968
  2293
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  2294
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  2295
now bundled exclusively with Isabelle.

Haskell Prelude to a small set of fundamental operations.
haftmann@48431
  2302
wenzelm@50646
  2303
* Command 'export_code': relative file names are interpreted
wenzelm@50646
  2304
relatively to master directory of current theory rather than the
wenzelm@50646
  2305
rather arbitrary current working directory.  INCOMPATIBILITY.

wenzelm@48205
  2307
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  2308
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  2309
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  2310
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  2311
with some care where this is really required.
wenzelm@48205
  2312
wenzelm@48792
  2313
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  2314
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  2315
given sort.  Example (in HOL):
wenzelm@48792
  2316
wenzelm@48792
  2317
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792

wenzelm@50646
  2358
arithmetic, datatypes/records) with potential proof reconstruction

wenzelm@49836
  2367
wenzelm@50646
  2368
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
  2369
directly.  INCOMPATIBILITY.
wenzelm@50646
  2370
wenzelm@50646
  2371
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
  2372
List.  INCOMPATIBILITY.
haftmann@49822
  2373
haftmann@49739

  2377
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
  2378
wenzelm@50646
  2379
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
  2380
wenzelm@50646
  2381

  2393
INCOMPATIBILITY.
wenzelm@50646
  2394
wenzelm@50646
  2395
* Generalized the definition of limits:
wenzelm@50646
  2396
wenzelm@50646
  2397
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  2398
    expresses that when the input values x converge to F then the
wenzelm@50646
  2399
    output f x converges to G.
wenzelm@50646
  2400
wenzelm@50646
  2401
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  2402
    infinity (at_bot).
wenzelm@50646
  2403
wenzelm@50646
  2404
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  2405
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  2406
wenzelm@50646
  2407
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
  2408
    at_top".
wenzelm@50646
  2409
wenzelm@50646
  2410
INCOMPATIBILITY.
wenzelm@50646
  2411
wenzelm@50646
  2412
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
  2413
lattice type classes.
wenzelm@50646
  2414
wenzelm@50646
  2415
* Theory "Library/Multiset": renamed
wenzelm@50646

  2417
    constant fold_mset ~> Multiset.fold
wenzelm@50646

  2420
INCOMPATIBILITY.
wenzelm@50646
  2421
wenzelm@50646
  2422
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  2423
changes as follows.
wenzelm@50646
  2424
wenzelm@50646
  2425
  - Renamed constants (and related lemmas)
Christian@49145
  2426
Christian@49145
  2427
      prefix ~> prefixeq
Christian@49145
  2428
      strict_prefix ~> prefix
Christian@49145
  2429
wenzelm@50646
  2430
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  2431
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  2432
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  2433
    Renamed lemmas accordingly.
wenzelm@50646
  2434
wenzelm@50646
  2435
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  2436
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  2437
    "list_hembeq (op =)".
wenzelm@50646
  2438
wenzelm@50646
  2439
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  2440
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  2441
    interpretations). The type class instances are now in theory
wenzelm@50646
  2442
    Library/Prefix_Order.
wenzelm@50646
  2443
wenzelm@50646
  2444
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
  2445
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516

  2464
INCOMPATIBILITY.
wenzelm@50646
  2465
wenzelm@50646
  2466
* New theory Library/Countable_Set.
wenzelm@50646
  2467
wenzelm@50646
  2468
* Theory Library/Debug and Library/Parallel provide debugging and
wenzelm@50646
  2469
parallel execution for code generated towards Isabelle/ML.
wenzelm@50646
  2470
wenzelm@50646
  2471
* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
  2472
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
  2473
extensional_funcset by an abbreviation, and renamed lemmas from
wenzelm@50646
  2474
extensional_funcset to PiE as follows:

wenzelm@50646
  2487
INCOMPATIBILITY.
wenzelm@50646
  2488
wenzelm@50646
  2489
* Theory Library/FinFun: theory of almost everywhere constant
wenzelm@50646
  2490
functions (supersedes the AFP entry "Code Generation for Functions as
wenzelm@50646
  2491
Data").
wenzelm@50646
  2492
wenzelm@50646
  2493
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
  2494
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
  2495
TYPE('a) as another parameter avoids unnecessary closures in generated
wenzelm@50646
  2496
code.
wenzelm@50646
  2497
wenzelm@50646
  2498
* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646
  2499
from sorted associative lists. Merging two trees with rbt_union may
wenzelm@50646
  2500
return a structurally different tree than before.  Potential
wenzelm@50646
  2501
INCOMPATIBILITY.
wenzelm@50646
  2502
wenzelm@50646
  2503

wenzelm@50646
  2508
wenzelm@50646
  2509
  "basis :: 'a::euclidean_space => nat => real"
wenzelm@50646
  2510
  "\<Chi>\<Chi> :: (nat => real) => 'a::euclidean_space"
wenzelm@50646
  2511
wenzelm@50646
  2512
on euclidean spaces by using the inner product "_ \<bullet> _" with
wenzelm@50646
  2513
vectors from the Basis set: "\<Chi>\<Chi> i. f i" is superseded by
wenzelm@50646
  2514
"SUM i : Basis. f i * r i".
wenzelm@50646
  2515
wenzelm@50646
  2516
  With this change the following constants are also changed or removed:
wenzelm@50646
  2517
wenzelm@50646
  2518
    DIM('a) :: nat  ~>  card (Basis :: 'a set)   (is an abbreviation)
wenzelm@50646
  2519
    a $$ i  ~>  inner a i  (where i : Basis)
wenzelm@50646
  2520
    cart_base i  removed
wenzelm@50646
  2521
    \<pi>, \<pi>'  removed
hoelzl@50526

hoelzl@50526
  2523
  Theorems about these constants where removed.
hoelzl@50526
  2524
hoelzl@50526

  2540
* HOL/Probability:
wenzelm@50646
  2541
wenzelm@50646
  2542
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
  2543
wenzelm@50646
  2544
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
  2545
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
  2546
    (borel_measurable_induct).
wenzelm@50646
  2547
wenzelm@50646
  2548
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a
wenzelm@50646
  2549
    projective family).
wenzelm@50646
  2550
wenzelm@50646
  2551
* HOL/Cardinals: Theories of ordinals and cardinals (supersedes the
wenzelm@50646
  2552
AFP entry "Ordinals_and_Cardinals").
wenzelm@50646
  2553
wenzelm@50646
  2554
* HOL/BNF: New (co)datatype package based on bounded natural functors
wenzelm@50646
  2555
with support for mixed, nested recursion and interesting non-free
wenzelm@50646
  2556
datatypes.
blanchet@48094
  2557
wenzelm@50991
  2558
* HOL/Finite_Set and Relation: added new set and relation operations
kuncar@50878
  2559
expressed by Finite_Set.fold.
kuncar@50878
  2560
kuncar@50878
  2561
* New theory HOL/Library/RBT_Set: implementation of sets by red-black
kuncar@50878
  2562
trees for the code generator.
kuncar@50878
  2563
kuncar@50878
  2564
* HOL/Library/RBT and HOL/Library/Mapping have been converted to
kuncar@50878
  2565
Lifting/Transfer.
kuncar@50878
  2566
possible INCOMPATIBILITY.
kuncar@50878
  2567

*** Document preparation ***
wenzelm@48206
  2573
wenzelm@50646
  2574
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  2575
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  2576
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  2577
wenzelm@50646
  2578
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  2579
instead of slightly exotic babel/greek.
wenzelm@48206
  2580
wenzelm@48616
  2581
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  2582
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  2583
document/root.tex.
wenzelm@48616
  2584
wenzelm@48657
  2585
* Simplified custom document/build script, instead of old-style
wenzelm@48657
  2586
document/IsaMakefile.  Minor INCOMPATIBILITY.
wenzelm@48657

wenzelm@48992
  2589
*** ML ***
wenzelm@48992
  2590
wenzelm@50646
  2591
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  2592
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  2593
hardware and Poly/ML runtime system.
wenzelm@50646
  2594
wenzelm@49869
  2595
* Type Seq.results and related operations support embedded error
wenzelm@49869
  2596
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  2597
informative errors in the absence of any usable results.
wenzelm@49869
  2598
wenzelm@48992
  2599
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  2600
formal device to inline positions into message text, but not
wenzelm@48992
  2601
necessarily printing visible text.

*** System ***
wenzelm@48206
  2605
wenzelm@48585
  2606
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  2607
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  2608
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  2609
session root directories for use with "isabelle build", similar to
wenzelm@51056
  2610
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  2611
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  2612
mkdir / make are rendered obsolete.
wenzelm@48736
  2613
wenzelm@51056
  2614
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  2615
regular isabelle build tool.  For example:
wenzelm@51056
  2616
wenzelm@51056
  2617
  isabelle build -s -b HOL
wenzelm@51056
  2618
wenzelm@48736
  2619
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  2620
wenzelm@48722
  2621
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  2622
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  2623
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  2624
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  2625
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  2626
wenzelm@48693
  2627
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  2628
required for "isabelle build", for example.
wenzelm@48693
  2629
wenzelm@50646
  2630
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  2631
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  2632
wenzelm@50646
  2633
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  2634
INCOMPATIBILITY.
wenzelm@50646
  2635
wenzelm@48844
  2636
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  2637
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  2638
version of Isabelle.

platform family: "linux", "macos", "windows".
wenzelm@50646
  2642
wenzelm@50646
  2643
* The ML system is configured as regular component, and no longer
wenzelm@50646
  2644
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  2645
for home-made settings.
wenzelm@50132
  2646
wenzelm@50701
  2647
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  2648
wenzelm@48206
  2649
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  2650
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  2651
configuration.
wenzelm@48206
  2652
wenzelm@48574
  2653
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  2654
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  2655
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  2656
settings manually, or use a Proof General version that has been
wenzelm@48574
  2657
bundled as Isabelle component.

*** General ***
wenzelm@45593
  2665
wenzelm@45614
  2666
* Prover IDE (PIDE) improvements:
wenzelm@45614
  2667
wenzelm@47585
  2668
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  2669
    command-line needs to be typed into the source buffer)
wenzelm@45614
  2670
  - markup for bound variables
wenzelm@47806
  2671
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  2672
  - support for user-defined Isar commands within the running session
wenzelm@47158
  2673
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  2674
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  2675
wenzelm@47806
  2676
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  2677
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  2678
commands to be used in the same theory where defined.
wenzelm@46485
  2679
wenzelm@47482
  2680
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  2681
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  2682
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  2683
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  2684
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  2685
wenzelm@47482
  2686
  context
wenzelm@47482
  2687
    fixes x y z :: 'a
wenzelm@47482
  2688
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  2689
  begin
wenzelm@47482
  2690
wenzelm@47482
  2691
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  2692
wenzelm@47482
  2693
  end
wenzelm@47482
  2694
wenzelm@47482
  2695
  thm my_trans
wenzelm@47482
  2696
wenzelm@47482
  2697
The most basic application is to factor-out context elements of
wenzelm@47482
  2698
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  2699
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  2700
wenzelm@47482
  2701
Any other local theory specification element works within the "context
wenzelm@47482
  2702
... begin ... end" block as well.
wenzelm@47482
  2703
wenzelm@47484
  2704
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  2705
given name in the context.  These may be later included in other
wenzelm@47484
  2706
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  2707
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  2708
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  2709
wenzelm@47829
  2710
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  2711
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  2712
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  2713
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  2714
indices of schematic variables.
wenzelm@47829
  2715
wenzelm@47829
  2716
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  2717
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  2718
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  2719
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  2720
etc. was exploited.
wenzelm@47829
  2721
wenzelm@47829
  2722
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  2723
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  2724
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  2725
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  2726
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  2727
of the materia
