*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
    11
wenzelm@60610
    12
* Improved scheduling for urgent print tasks (e.g. command state output,
wenzelm@60610
    13
interactive queries) wrt. long-running background tasks.
wenzelm@60610
    14
wenzelm@60986
    15
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@60984
    16
Isabelle/ML and official Standard ML. Configuration option "ML_debugger"
wenzelm@60984
    17
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@60984
    18
'SML_file_no_debug' control compilation of sources with debugging
wenzelm@60984
    19
information. The Debugger panel allows to set breakpoints (via context
wenzelm@60984
    20
menu), step through stopped threads, evaluate local ML expressions etc.
wenzelm@60984
    21
At least one Debugger view needs to be active to have any effect on the
wenzelm@60984
    22
running ML program.
wenzelm@60984
    23
wenzelm@61173
    24
* The main Isabelle executable is managed as single-instance Desktop
wenzelm@61173
    25
application uniformly on all platforms: Linux, Windows, Mac OS X.
wenzelm@61170

wenzelm@60406
    28
*** Isar ***
wenzelm@60406
    29
wenzelm@60406
    30
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@60406
    31
proof body as well, abstracted over relevant parameters.
wenzelm@60406
    32
wenzelm@60477
    33
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@60477
    34
parameter scope for of each clause.
wenzelm@60477
    35
wenzelm@60408
    36
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@60408
    37
statements: result is abstracted over unknowns.
wenzelm@60408
    38
wenzelm@60414
    39
* Local goals ('have', 'show', 'hence', 'thus') allow structured
wenzelm@60414
    40
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@60555
    41
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
    42
example:
wenzelm@60414
    43
wenzelm@60414
    44
  have result: "C x y"
wenzelm@60414
    45
    if "A x" and "B y"
wenzelm@60414
    46
    for x :: 'a and y :: 'a
wenzelm@60414
    47
    <proof>
wenzelm@60414
    48
wenzelm@60449
    49
The local assumptions are bound to the name "that". The result is
wenzelm@60449
    50
exported from context of the statement as usual. The above roughly
wenzelm@60414
    51
corresponds to a raw proof block like this:
wenzelm@60414
    52
wenzelm@60414
    53
  {
wenzelm@60414
    54
    fix x :: 'a and y :: 'a
wenzelm@60449
    55
    assume that: "A x" "B y"
wenzelm@60414
    56
    have "C x y" <proof>
wenzelm@60414
    57
  }
wenzelm@60414
    58
  note result = this
wenzelm@60406
    59
wenzelm@60555
    60
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
    61
instead of 'assume' above.
wenzelm@60555
    62
wenzelm@60595
    63
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
    64
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@60595
    65
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows:
wenzelm@60595
    66
wenzelm@60595
    67
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
    68
wenzelm@60595
    69
or:
wenzelm@60595
    70
wenzelm@60595
    71
  show "C x" if "A x" "B x" for x
wenzelm@60595
    72
wenzelm@60595
    73
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
    74
wenzelm@60595
    75
  show "C x" when "A x" "B x" for x
wenzelm@60595
    76
wenzelm@60406
    77
* New command 'supply' supports fact definitions during goal refinement
wenzelm@60406
    78
('apply' scripts).
wenzelm@60406
    79
wenzelm@60459
    80
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
    81
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
    82
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
    83
of the local context elements yet.
wenzelm@60459
    84
wenzelm@60455
    85
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
    86
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
    87
wenzelm@60455
    88
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
    89
  then have something
wenzelm@60455
    90
  proof cases
wenzelm@60455
    91
    case a
wenzelm@60455
    92
    then show ?thesis <proof>
wenzelm@60455
    93
  next
wenzelm@60455
    94
    case b
wenzelm@60455
    95
    then show ?thesis <proof>
wenzelm@60455
    96
  next
wenzelm@60455
    97
    case c
wenzelm@60455
    98
    then show ?thesis <proof>
wenzelm@60455
    99
  qed
wenzelm@60455
   100
wenzelm@60565
   101
* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
   102
wenzelm@60565
   103
  case a: (c xs)
wenzelm@60565
   104
  case a [attributes]: (c xs)
wenzelm@60565
   105
wenzelm@60565
   106
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   107
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   108
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
   109
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565
   110
and always put attributes in front.
wenzelm@60565
   111
wenzelm@60618
   112
* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   113
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   114
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   115
'..' more accurately as "by standard" instead of "by rule".
wenzelm@60618
   116
wenzelm@60631
   117
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   118
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   119
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631
   120
manual.
wenzelm@60631
   121
wenzelm@61166
   122
* Proof method "goal_cases" turns the current subgoals into cases within
wenzelm@61166
   123
the context; the conclusion is bound to variable ?case in each case. For
wenzelm@61166
   124
example:
wenzelm@60617
   125
wenzelm@60617
   126
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60622
   127
  and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z"
wenzelm@61166
   128
proof goal_cases
wenzelm@60622
   129
  case (1 x)
wenzelm@60622
   130
  then show ?case using \<open>A x\<close> \<open>B x\<close> sorry
wenzelm@60622
   131
next
wenzelm@60622
   132
  case (2 y z)
wenzelm@60622
   133
  then show ?case using \<open>U y\<close> \<open>V z\<close> sorry
wenzelm@60622
   134
qed
wenzelm@60622
   135
wenzelm@60622
   136
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60622
   137
  and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z"
wenzelm@61166
   138
proof goal_cases
wenzelm@60617
   139
  case prems: 1
wenzelm@60617
   140
  then show ?case using prems sorry
wenzelm@60617
   141
next
wenzelm@60617
   142
  case prems: 2
wenzelm@60617
   143
  then show ?case using prems sorry
wenzelm@60617
   144
qed
wenzelm@60578
   145
wenzelm@60581
   146
* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   147
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   148
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   149
done more adequately by other means (e.g. 'consider').
wenzelm@60581
   150
wenzelm@60551
   151
* Nesting of Isar goal structure has been clarified: the context after
wenzelm@60551
   152
the initial backwards refinement is retained for the whole proof, within
wenzelm@60551
   153
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@60551
   154
relevant for 'using', 'including', 'supply':
wenzelm@60551
   155
wenzelm@60551
   156
  have "A \<and> A" if a: A for A
wenzelm@60551
   157
    supply [simp] = a
wenzelm@60551
   158
  proof
wenzelm@60551
   159
    show A by simp
wenzelm@60551
   160
  next
wenzelm@60551
   161
    show A by simp
wenzelm@60551
   162
  qed
wenzelm@60551
   163
wenzelm@60554
   164
* Method "sleep" succeeds after a real-time delay (in seconds). This is
wenzelm@60554
   165
occasionally useful for demonstration and testing purposes.
wenzelm@60554
   166
wenzelm@60406
   167
wenzelm@60331
   168
*** Pure ***
wenzelm@60331
   169
wenzelm@60489
   170
* The vacuous fact "TERM x" may be established "by fact" or as `TERM x`
wenzelm@60489
   171
as well, not just "by this" or "." as before.
wenzelm@60489
   172
wenzelm@60331
   173
* Configuration option rule_insts_schematic has been discontinued
wenzelm@60331
   174
(intermediate legacy feature in Isabelle2015).  INCOMPATIBILITY.
wenzelm@60331
   175
haftmann@60349
   176
* Abbreviations in type classes now carry proper sort constraint.
haftmann@60349
   177
Rare INCOMPATIBILITY in situations where the previous misbehaviour
haftmann@60349
   178
has been exploited previously.
haftmann@60349
   179
haftmann@60349
   180
* Refinement of user-space type system in type classes: pseudo-local
haftmann@60349
   181
operations behave more similar to abbreviations.  Potential
haftmann@60349
   182
INCOMPATIBILITY in exotic situations.
haftmann@60349
   183
haftmann@60349
   184
nipkow@60171
   185
*** HOL ***
nipkow@60171
   186
wenzelm@61118
   187
* Qualification of various formal entities in the libraries is done more
wenzelm@61118
   188
uniformly via "context begin qualified definition ... end" instead of
wenzelm@61118
   189
old-style "hide_const (open) ...". Consequently, both the defined
wenzelm@61118
   190
constant and its defining fact become qualified, e.g. Option.is_none and
wenzelm@61118
   191
Option.is_none_def. Occasional INCOMPATIBILITY in applications.
wenzelm@61118
   192
haftmann@61125
   193
* Combinator to represent case distinction on products is named "uncurry",
haftmann@61125
   194
with "split" and "prod_case" retained as input abbreviations.
haftmann@61126
   195
Partially applied occurences of "uncurry" with eta-contracted body
haftmann@61126
   196
terms are not printed with special syntax, to provide a compact
haftmann@61126
   197
notation and getting rid of a special-case print translation.
haftmann@61126
   198
Hence, the "uncurry"-expressions are printed the following way:
haftmann@61126
   199
a) fully applied "uncurry f p": explicit case-expression;
haftmann@61126
   200
b) partially applied with explicit double lambda abstraction in
haftmann@61126
   201
the body term "uncurry (%a b. t [a, b])": explicit paired abstraction;
haftmann@61126
   202
c) partially applied with eta-contracted body term "uncurry f":
haftmann@61126
   203
no special syntax, plain "uncurry" combinator.
haftmann@61126
   204
This aims for maximum readability in a given subterm.
haftmann@61125
   205
INCOMPATIBILITY.
haftmann@61125
   206
wenzelm@61069
   207
* Some old and rarely used ASCII replacement syntax has been removed.
wenzelm@61069
   208
INCOMPATIBILITY, standard syntax with symbols should be used instead.
wenzelm@61069
   209
The subsequent commands help to reproduce the old forms, e.g. to
wenzelm@61069
   210
simplify porting old theories:
wenzelm@61069
   211
wenzelm@61069
   212
  type_notation Map.map  (infixr "~=>" 0)
wenzelm@61069
   213
  notation Map.map_comp  (infixl "o'_m" 55)
wenzelm@61069
   214
wenzelm@61143
   215
* The alternative notation "\<Colon>" for type and sort constraints has been
wenzelm@61143
   216
removed: in LaTeX document output it looks the same as "::".
wenzelm@61143
   217
INCOMPATIBILITY, use plain "::" instead.
wenzelm@61143
   218
wenzelm@60841
   219
* Theory Map: lemma map_of_is_SomeD was a clone of map_of_SomeD and has
wenzelm@60841
   220
been removed. INCOMPATIBILITY.
wenzelm@60841
   221
lars@60712
   222
* Quickcheck setup for finite sets.
lars@60712
   223
nipkow@60171
   224
* Discontinued simp_legacy_precond. Potential INCOMPATIBILITY.
wenzelm@60138
   225
blanchet@60306
   226
* Sledgehammer:
blanchet@60306
   227
  - Proof reconstruction has been improved, to minimize the incidence of
blanchet@60306
   228
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
   229
  - Auto Sledgehammer now minimizes and preplays the results.
blanchet@61030
   230
  - Handle Vampire 4.0 proof output without raising exception.
blanchet@61043
   231
  - Eliminated "MASH" environment variable. Use the "MaSh" option in
blanchet@61043
   232
    Isabelle/jEdit instead. INCOMPATIBILITY.
blanchet@60306
   233
blanchet@60310
   234
* Nitpick:
blanchet@60310
   235
  - Removed "check_potential" and "check_genuine" options.
blanchet@60310
   236
traytel@60922
   237
* New commands lift_bnf and copy_bnf for lifting (copying) a BNF structure
traytel@60922
   238
  on the raw type to an abstract type defined using typedef.
traytel@60920
   239
haftmann@60868
   240
* Division on integers is bootstrapped directly from division on
haftmann@60868
   241
naturals and uses generic numeral algorithm for computations.
haftmann@60868
   242
Slight INCOMPATIBILITY, simproc numeral_divmod replaces and generalizes
haftmann@60868
   243
former simprocs binary_int_div and binary_int_mod
haftmann@60868
   244
haftmann@60516
   245
* Tightened specification of class semiring_no_zero_divisors.  Slight
haftmann@60516
   246
INCOMPATIBILITY.
haftmann@60516
   247
haftmann@60688
   248
* Class algebraic_semidom introduces common algebraic notions of
haftmann@60688
   249
integral (semi)domains, particularly units.  Although
haftmann@60517
   250
logically subsumed by fields, is is not a super class of these
haftmann@60517
   251
in order not to burden fields with notions that are trivial there.
haftmann@60688
   252
haftmann@60688
   253
* Class normalization_semidom specifies canonical representants
haftmann@60688
   254
for equivalence classes of associated elements in an integral
haftmann@60688
   255
(semi)domain.  This formalizes associated elements as well.
haftmann@60688
   256
haftmann@60688
   257
* Abstract specification of gcd/lcm operations in classes semiring_gcd,
haftmann@60688
   258
semiring_Gcd, semiring_Lcd.  Minor INCOMPATIBILITY: facts gcd_nat.commute
haftmann@60688
   259
and gcd_int.commute are subsumed by gcd.commute, as well as gcd_nat.assoc
haftmann@60688
   260
and gcd_int.assoc by gcd.assoc.
haftmann@60517
   261
haftmann@60429
   262
* Former constants Fields.divide (_ / _) and Divides.div (_ div _)
haftmann@60354
   263
are logically unified to Rings.divide in syntactic type class
haftmann@60429
   264
Rings.divide, with infix syntax (_ div _).  Infix syntax (_ / _)
haftmann@60429
   265
for field division is added later as abbreviation in class Fields.inverse.
haftmann@60516
   266
INCOMPATIBILITY,  instantiations must refer to Rings.divide rather
haftmann@60429
   267
than the former separate constants, hence infix syntax (_ / _) is usually
haftmann@60429
   268
not available during instantiation.
haftmann@60354
   269
Mathias@60397
   270
* Library/Multiset:
Mathias@60397
   271
  - Renamed multiset inclusion operators:
Mathias@60397
   272
      < ~> <#
Mathias@60397
   273
      \<subset> ~> \<subset>#
Mathias@60397
   274
      <= ~> <=#

*** General ***
wenzelm@57941
   390
wenzelm@59939
   391
* Local theory specification commands may have a 'private' or
wenzelm@59990
   392
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
   393
as provided by some "context begin ... end" block. For example:
wenzelm@59926
   394
wenzelm@59926
   395
  context
wenzelm@59926
   396

* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
   410
naming policy.
wenzelm@59901
   411
wenzelm@59951
   412
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
   413
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
   414
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
   415
wenzelm@59951
   416
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
   417
together with an attribute to maintain the content incrementally. This
wenzelm@59951
   418
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
   419
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
   420
wenzelm@59951
   421
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
   422
schematically expanded before search. Search results match the naive
wenzelm@59951
   423
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
   424
INCOMPATIBILITY.
wenzelm@59648
   425
wenzelm@59569
   426
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
   427
theory context.
wenzelm@57941
   428
wenzelm@58928
   429
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
   430
context, without implicit global state. Potential for accidental
wenzelm@58928
   431
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
   432
wenzelm@60116
   433
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60116
   434
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60116
   435
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60116
   436
sources.
wenzelm@60116
   437
wenzelm@59951
   438
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
   439
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
   440
wenzelm@60119
   441
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   442
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   443
method provides basic fact/term matching in addition to
wenzelm@60119
   444
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   445
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
   446
documentation provides an entry "eisbach" for the Eisbach User Manual.

wenzelm@58540
   459

wenzelm@58540
   460
marker, SideKick parser.
wenzelm@58524
   461
wenzelm@58551
   462
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   463
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   464
the editor (hyperlinks, completion etc.).
wenzelm@58551
   465
wenzelm@58785
   466
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   467
Options / Text Area).
wenzelm@58785
   468
wenzelm@60091
   469
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   470
display of 'thy_deps', 'class_deps' etc.
wenzelm@60010
   471
wenzelm@60116
   472
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60116
   473
restrict the visualized hierarchy.
wenzelm@60095
   474
wenzelm@60072
   475
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
   476
managed by the Sledgehammer panel) wrt. ongoing document processing.
wenzelm@60072

*** Document preparation ***
wenzelm@59951
   480
wenzelm@59951
   481
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   482
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   483
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   484
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   485
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   486
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   487
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   488
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   489
wenzelm@60010
   490
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60010
   491
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60010
   492
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60010
   493
as argument to other macros (such as footnotes).
wenzelm@60010
   494
wenzelm@60010
   495
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60010
   496
style.
wenzelm@60010
   497
wenzelm@60010
   498
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60010
   499
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60010
   500
wenzelm@59951
   501
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   502
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   503
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   504
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   505
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   506
wenzelm@59951
   507
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   508
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   509
Only the margin for document output may be changed, but not the global
wenzelm@59951
   510
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   511
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   512
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   513
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   514
wenzelm@60299
   515
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   516
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
   517
copying of the document/ directory is no longer supported. Minor
wenzelm@60299
   518
INCOMPATIBILITY.

haftmann@58202
   522
wenzelm@59835
   523
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   524
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   525
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   526
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   527
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   528
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   529
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   530
variable declarations or dummy patterns instead.
wenzelm@59835
   531
wenzelm@60010
   532
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60010
   533
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60010
   534
("_") that stand for anonymous local variables.
wenzelm@60010
   535
wenzelm@59951
   536
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   537
incremented to avoid material in the proof context. Rare
wenzelm@59951
   538
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   539
different index.
wenzelm@59951
   540
wenzelm@60011
   541
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60011
   542
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60011
   543
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60011
   544
like "(- 1) ^ n".
haftmann@58410
   545
wenzelm@58421
   546
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421

INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
   548

blanchet@57983
   553
* New (co)datatype package:
blanchet@58374
   554
  - The 'datatype_new' command has been renamed 'datatype'. The old
blanchet@58374
   555
    command of that name is now called 'old_datatype' and is provided
blanchet@58374
   556
    by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58374
   557
    'isabelle doc datatypes' for information on porting.
blanchet@58374
   558
    INCOMPATIBILITY.
blanchet@57983
   559
  - Renamed theorems:
blanchet@57983
   560
      disc_corec ~> corec_disc
blanchet@57983
   561
      disc_corec_iff ~> corec_disc_iff

      strong_coinduct ~> coinduct_strong
blanchet@57983
   572
      weak_case_cong ~> case_cong_weak
blanchet@57983
   573
    INCOMPATIBILITY.
blanchet@58192
   574
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192
   575
    "codatatype" has been renamed "plugins del: code".
blanchet@58192
   576
    INCOMPATIBILITY.
blanchet@58044
   577
  - The rules "set_empty" have been removed. They are easy
blanchet@58044
   578
    consequences of other set rules "by auto".
blanchet@58044
   579
    INCOMPATIBILITY.
blanchet@58044
   580
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
   581
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
   582
    method when more than one case rule is applicable (e.g., an
blanchet@57990
   583
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   584
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
   585
    (e.g. "cases w rule: widget.exhaust").
blanchet@57990
   586
    INCOMPATIBILITY.
blanchet@59675
   587
  - Renamed theories:
blanchet@59675
   588
      BNF_Comp ~> BNF_Composition
blanchet@59675
   589
      BNF_FP_Base ~> BNF_Fixpoint_Base

      BNF_LFP ~> BNF_Least_Fixpoint
blanchet@59675
   592
      BNF_Constructions_on_Wellorders ~> BNF_Wellorder_Constructions
blanchet@59675
   593
      Cardinals/Constructions_on_Wellorders ~> Cardinals/Wellorder_Constructions
blanchet@59675
   594
    INCOMPATIBILITY.
wenzelm@60115
   595
  - Lifting and Transfer setup for basic HOL types sum and prod (also
wenzelm@60115
   596
    option) is now performed by the BNF package. Theories Lifting_Sum,
wenzelm@60115
   597
    Lifting_Product and Lifting_Option from Main became obsolete and
wenzelm@60115
   598
    were removed. Changed definitions of the relators rel_prod and
wenzelm@60115
   599
    rel_sum (using inductive).
traytel@60112
   600
    INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead
wenzelm@60115
   601
    of rel_prod_def and rel_sum_def.
wenzelm@60115
   602
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60115
   603
    changed (e.g. map_prod_transfer ~> prod.map_transfer).
wenzelm@60261
   604
  - Parametricity theorems for map functions, relators, set functions,
wenzelm@60261
   605
    constructors, case combinators, discriminators, selectors and
wenzelm@60261
   606
    (co)recursors are automatically proved and registered as transfer
wenzelm@60261
   607
    rules.
blanchet@57983
   608
blanchet@57983
   609
* Old datatype package:
blanchet@58310
   610
  - The old 'datatype' command has been renamed 'old_datatype', and
blanchet@58374
   611
    'rep_datatype' has been renamed 'old_rep_datatype'. They are
blanchet@58374
   612
    provided by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58310
   613
    'isabelle doc datatypes' for information on porting.
blanchet@58374
   614
    INCOMPATIBILITY.
blanchet@57983
   615
  - Renamed theorems:
blanchet@57983
   616
      weak_case_cong ~> case_cong_weak
blanchet@57983
   617
    INCOMPATIBILITY.
blanchet@58374
   618
  - Renamed theory:
blanchet@58374
   619
      ~~/src/HOL/Datatype.thy ~> ~~/src/HOL/Library/Old_Datatype.thy
blanchet@58374
   620
    INCOMPATIBILITY.
blanchet@57983
   621
blanchet@59039
   622
* Nitpick:
wenzelm@60011
   623
  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   624
    operations.
blanchet@59039
   625
blanchet@57737
   626
* Sledgehammer:
blanchet@59511
   627
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   628
    default.
blanchet@59965
   629
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   630
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
   631
  - Minimization is now always enabled by default.
wenzelm@60011
   632
    Removed sub-command:
blanchet@57737
   633
      min
blanchet@59967
   634
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039
   635
    dramatically improved.
blanchet@59039
   636
  - Improved support for CVC4 and veriT.
blanchet@57737
   637
blanchet@58062
   638
* Old and new SMT modules:
blanchet@58067
   639
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   640
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   641
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   642
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   643
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
   644
    point to it.
blanchet@58062
   645
    INCOMPATIBILITY.
blanchet@58067
   646
  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
   647
    INCOMPATIBILITY.
wenzelm@59569
   648
  - New option 'smt_reconstruction_step_timeout' to limit the
wenzelm@59569
   649
    reconstruction time of Z3 proof steps in the new 'smt' method.
boehmes@59216
   650
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
   651
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060
   652
wenzelm@60261
   653
* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
   654
that have as a return type a datatype containing a subtype. This
wenzelm@60261
   655
overcomes long-time limitations in the area of code generation and
wenzelm@60261
   656
lifting, and avoids tedious workarounds.
kuncar@60258
   657
wenzelm@60010
   658
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60010
   659
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60010
   660
Minor INCOMPATIBILITY.
wenzelm@60010
   661
wenzelm@60010
   662
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60010
   663
wenzelm@60010
   664
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60010
   665
non-termination in case of distributing a division. With this change
wenzelm@60010
   666
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60010
   667
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60010
   668
wenzelm@60010
   669
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60010
   670
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60010
   671
wenzelm@60010
   672
* Class linordered_semidom really requires no zero divisors.
wenzelm@60010
   673
INCOMPATIBILITY.
wenzelm@60010
   674
wenzelm@60010
   675
* Classes division_ring, field and linordered_field always demand
wenzelm@60010
   676
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60010
   677
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60010
   678
wenzelm@60010
   679
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit
wenzelm@60010
   680
additive inverse operation. INCOMPATIBILITY.
wenzelm@60010
   681
lp15@60020
   682
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
   683
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
   684
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
   685
wenzelm@60010
   686
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60010
   687
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60010
   688
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60010
   689
needed.
wenzelm@60010
   690
wenzelm@60010
   691
* New library of properties of the complex transcendental functions sin,
wenzelm@60010
   692
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60010
   693
wenzelm@60010
   694
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60010
   695
that admits numeric types including nat, int, real and complex.
wenzelm@60010
   696
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60010
   697
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60010
   698
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60010
   699
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60010
   700
wenzelm@60010
   701
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60010
   702
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60010
   703
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60010
   704
"nat_floor"/"nat_ceiling".
wenzelm@60010
   705
wenzelm@60010
   706
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60010
   707
type class hierarchy:
wenzelm@60010
   708
  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60010
   709
  field_inverse_zero ~> inverse_zero
wenzelm@60010
   710
  field_divide_inverse ~> divide_inverse
wenzelm@60010
   711
  field_inverse ~> left_inverse
wenzelm@60010
   712
Minor INCOMPATIBILITY.
wenzelm@60010
   713
wenzelm@60010
   714
* Eliminated fact duplicates:
wenzelm@60010
   715
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60010
   716
  mult_less_imp_less_left ~> mult_left_less_imp_less
wenzelm@60010
   717
Minor INCOMPATIBILITY.
wenzelm@60010
   718
wenzelm@60010
   719
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60010
   720
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60010
   721
wenzelm@60010
   722
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60010
   723
  dvd_reduce ~> dvd_add_triv_right_iff
wenzelm@60010
   724
  dvd_plus_eq_right ~> dvd_add_right_iff
wenzelm@60010
   725
  dvd_plus_eq_left ~> dvd_add_left_iff
wenzelm@60010
   726
Minor INCOMPATIBILITY.
wenzelm@60010
   727
wenzelm@60010
   728
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"
wenzelm@60010
   729
and part of theory Main.
wenzelm@60010
   730
  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60010
   731
INCOMPATIBILITY.
wenzelm@60010
   732
wenzelm@60010
   733
* Lemma name consolidation: divide_Numeral1 ~> divide_numeral_1. Minor
wenzelm@60010
   734
INCOMPATIBILITY.
wenzelm@60010
   735
wenzelm@60010
   736
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60010
   737
Fact rename:
wenzelm@60010
   738
    listsum_def ~> listsum.eq_foldr
wenzelm@60010
   739
INCOMPATIBILITY.
wenzelm@60010
   740
wenzelm@60010
   741
* Product over lists via constant "listprod".
wenzelm@60010
   742
wenzelm@60010
   743
* Theory List: renamed drop_Suc_conv_tl and nth_drop' to
wenzelm@60010
   744
Cons_nth_drop_Suc.
nipkow@58247
   745
Andreas@58626
   746
* New infrastructure for compiling, running, evaluating and testing
wenzelm@59569
   747
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
   748
HOL/Codegenerator_Test/Code_Test* for examples.
wenzelm@58008
   749
wenzelm@60010
   750
* Library/Multiset:
blanchet@59813
   751
  - Introduced "replicate_mset" operation.
blanchet@59813
   752
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
   753
    "Library/Multiset_Order".
blanchet@59958
   754
  - Renamed multiset ordering:

      \<subseteq># ~> #\<subseteq>#
blanchet@59958
   759
    INCOMPATIBILITY.
blanchet@59986
   760
  - Introduced abbreviations for ill-named multiset operations:
blanchet@59986
   761
      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
   762
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986
   763
    INCOMPATIBILITY.
blanchet@59813
   764
  - Renamed
blanchet@59813
   765
      in_multiset_of ~> in_multiset_in_set
nipkow@59998

      Multiset.fold ~> fold_mset
nipkow@59998
   767
      Multiset.filter ~> filter_mset
blanchet@59813
   768
    INCOMPATIBILITY.
nipkow@59949
   769
  - Removed mcard, is equal to size.
blanchet@59813

    INCOMPATIBILITY.
blanchet@59813
   780
wenzelm@60010
   781
* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60010
   782
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60010
   783
The "sos_cert" functionality is invoked as "sos" with additional
wenzelm@60010
   784
argument. Minor INCOMPATIBILITY.
wenzelm@60010
   785
wenzelm@60010
   786
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60010
   787
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60010
   788
hardware floating point arithmetic to randomly discover potential
wenzelm@60011
   789
counterexamples. Counterexamples are certified with the "approximation"
wenzelm@60010
   790
method. See HOL/Decision_Procs/ex/Approximation_Quickcheck_Ex.thy for
wenzelm@60010
   791
examples.
immler@58990
   792
hoelzl@59354
   793
* HOL-Probability: Reworked measurability prover
wenzelm@60011
   794
  - applies destructor rules repeatedly
hoelzl@59354
   795
  - removed application splitting (replaced by destructor rule)
wenzelm@59569
   796
  - added congruence rules to rewrite measure spaces under the sets
wenzelm@59569
   797
    projection
wenzelm@59569
   798
wenzelm@60010
   799

   803
*** ML ***
blanchet@58066
   804
wenzelm@60010
   805
* Subtle change of name space policy: undeclared entries are now
wenzelm@60010
   806
considered inaccessible, instead of accessible via the fully-qualified

   807
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60010
   808
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60011
   809
contemporary applications use the strict Name_Space.check (and
wenzelm@60010
   810
derivatives) instead, which is not affected by the change. Potential
wenzelm@60010
   811
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
   812
wenzelm@60096
   813
* Subtle change of error semantics of Toplevel.proof_of: regular user
wenzelm@60096
   814
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60096
   815
wenzelm@59951
   816
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
   817
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
   818
wenzelm@59951
   819
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
   820
INCOMPATIBILITY.
wenzelm@59951
   821
wenzelm@59951
   822
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
   823
sections have been discontinued, in favour of the more elementary
wenzelm@59951
   824
Multithreading.synchronized and its high-level derivative
wenzelm@59951
   825
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
   826
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
   827
nested.
wenzelm@59951
   828
wenzelm@60010
   829
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60010
   830
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
   831
wenzelm@59621
   832
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
   833
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
   834
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
   835
INCOMPATIBILITY.
wenzelm@59621
   836
wenzelm@59582
   837
* Elementary operations in module Thm are no longer pervasive.
wenzelm@59582
   838
INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,
wenzelm@59582
   839
Thm.term_of etc.
wenzelm@59582
   840
wenzelm@58963
   841
* Proper context for various elementary tactics: assume_tac,
wenzelm@59498
   842
resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498
   843
compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
   844
blanchet@58066
   845
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
   846
PARALLEL_GOALS.
blanchet@58066
   847
wenzelm@59564
   848
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
   849
which also allows to specify a fork priority.
wenzelm@59564
   850
wenzelm@59936
   851
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936
   852
@{command_keyword COMMAND} (usually without quotes and with PIDE
wenzelm@59936
   853
markup). Minor INCOMPATIBILITY.
wenzelm@59936
   854
wenzelm@60010
   855
* Cartouches within ML sources are turned into values of type
wenzelm@60010
   856
Input.source (with formal position information).

*** System ***
wenzelm@58610
   860
wenzelm@59951
   861
* The Isabelle tool "update_cartouches" changes theory files to use
wenzelm@59951
   862
cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@59951
   863
wenzelm@60108
   864
* The Isabelle tool "build" provides new options -X, -k, -x.
wenzelm@59951
   865
wenzelm@59951
   866
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
   867
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
   868
corresponding theory. Parametrization is possible using environment
wenzelm@59951
   869
variables, or ML snippets in the most extreme cases. Minor
wenzelm@59951
   870
INCOMPATIBILITY.
wenzelm@58842
   871
wenzelm@59200
   872
* JVM system property "isabelle.threads" determines size of Scala thread
wenzelm@59200
   873
pool, like Isabelle system option "threads" for ML.
wenzelm@59200
   874
wenzelm@59201
   875
* JVM system property "isabelle.laf" determines the default Swing
wenzelm@59201
   876
look-and-feel, via internal class name or symbolic name as in the jEdit
wenzelm@59201
   877
menu Global Options / Appearance.
wenzelm@59201
   878
wenzelm@59951
   879
* Support for Proof General and Isar TTY loop has been discontinued.
wenzelm@60010

wenzelm@54702
   887
*** General ***
wenzelm@54702
   888
wenzelm@57452
   889
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
   890
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
   891
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
   892
environment is restricted to the Standard ML implementation of
wenzelm@57452
   893
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
   894
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
   895
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
   896
some examples.
wenzelm@56499
   897
wenzelm@57504
   898
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
   899
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
   900
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
   901
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   902
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   903
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   904
induction is done after these methods or when the names of free and
wenzelm@57504
   905
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   906
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   907
wenzelm@56232
   908
* More static checking of proof methods, which allows the system to
wenzelm@56232
   909
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
   910
processed in the original proof context as far as possible, before
wenzelm@56232
   911
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   912
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   913
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   914
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   915
proof tools.
wenzelm@56232
   916
wenzelm@57452
   917
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   918
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   919
supports input via ` (backquote).
wenzelm@57452
   920
wenzelm@57452
   921
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   922
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   923
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   924
wenzelm@57452
   925
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   926
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   927
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   928
Minor INCOMPATIBILITY.
wenzelm@57452
   929
wenzelm@57452
   930
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   931
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   932
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   933
INCOMPATIBILITY.
wenzelm@57452
   934
wenzelm@57452
   935
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   936
which results in an active hyperlink within the text.
wenzelm@57452
   937
wenzelm@57452
   938
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   939
not check existence within the file-system.
wenzelm@57452
   940
wenzelm@57452
   941
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   942
isar-ref, jedit, system.

   945
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   946
wenzelm@57650
   947
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   948
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   949
buffer.
wenzelm@57452
   950
wenzelm@57452
   951
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   952
to PIDE hyperlinks.
wenzelm@57452
   953
wenzelm@57452
   954
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   955
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   956
wenzelm@57452
   957
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   958
auxiliary ML files.
wenzelm@57423
   959
wenzelm@57423
   960
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   961
templates, completion language context, name-space completion,
wenzelm@57423
   962
file-name completion, spell-checker completion.
wenzelm@57423
   963
wenzelm@57423
   964
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   965
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   966
keystrokes with slow / remote graphics displays.
wenzelm@57423
   967
wenzelm@57833
   968
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   969
item, depending on Isabelle options.
wenzelm@57833
   970
wenzelm@57423
   971
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   972
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   973
caret".
wenzelm@56342
   974
wenzelm@56580
   975
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   976
completion popup and context-menu.
wenzelm@56554
   977
wenzelm@56879
   978
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   979
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   980
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   981
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   982
wenzelm@56901
   983
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   984
to highlight text via regular expression.
wenzelm@56901
   985
wenzelm@54881
   986
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   987
General") allows to specify additional print modes for the prover
wenzelm@54881
   988
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   989
"isabelle jedit -m MODE".
wenzelm@54881
   990
wenzelm@56505
   991
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   992
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   993
wenzelm@57822
   994
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   995
imports) are automatically removed from the document model.
wenzelm@57822
   996
wenzelm@57869
   997
* Improved monitor panel.
wenzelm@57869
   998
wenzelm@56838
   999
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1000
more robust treatment of threads and interrupts.
wenzelm@56838
  1001
wenzelm@56939
  1002
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1003
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1004
"Detach" a copy where this makes sense.
wenzelm@56939
  1005
wenzelm@57452
  1006
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57594
  1007
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
  1008
within the context.

wenzelm@57504
  1013
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1014
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1015
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1016
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1017
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1018
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1019
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
  1020
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
  1021
Axclass.arity_axiomatization.
wenzelm@57504
  1022
wenzelm@56245
  1023
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1024
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1025
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1026
renaming needs to be applied:
wenzelm@56245
  1027
wenzelm@56245
  1028
  ==             ~>  Pure.eq
wenzelm@56245
  1029
  ==>            ~>  Pure.imp
wenzelm@56245
  1030
  all            ~>  Pure.all
wenzelm@56245
  1031
  TYPE           ~>  Pure.type
wenzelm@56245
  1032
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1033
wenzelm@56245
  1034
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1035
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1036
old constants:
wenzelm@56245
  1037
wenzelm@56245
  1038
setup {*
wenzelm@56245
  1039
  fn thy => thy
wenzelm@56245
  1040
    |> Sign.root_path
wenzelm@56245
  1041
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1042
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1043
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1044
    |> Sign.restore_naming thy
wenzelm@56245
  1045
*}
wenzelm@56245
  1046
wenzelm@56245
  1047
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1048
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1049
the auxiliary aliases are deleted.
wenzelm@56245
  1050
wenzelm@55143
  1051
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1052
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1053
instantiated theorem.
wenzelm@55143
  1054
wenzelm@55152
  1055
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1056
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1057
where instantiations with schematic variables are intended (for
wenzelm@55152
  1058
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1059
following temporary definition may help to port old applications:
wenzelm@55152
  1060
wenzelm@55152
  1061
  attribute_setup standard =
wenzelm@55152
  1062
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1063
wenzelm@55001
  1064
* More thorough check of proof context for goal statements and
wenzelm@55006
  1065
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1066
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1067
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1068
primitive Thm.assume_hyps.
wenzelm@55001
  1069
wenzelm@55108
  1070
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1071
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1072
differently, e.g. via cartouches).
wenzelm@57452
  1073
wenzelm@57504
  1074
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1075
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1076
wenzelm@57452
  1077
* Code generator preprocessor: explicit control of simp tracing on a

wenzelm@57452
  1114
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
  1115
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
  1116
behaviour of the simplifier can be restored like this: declare/using

  1178
    INCOMPATIBILITY.
wenzelm@57452
  1179

blanchet@57091
  1185
    INCOMPATIBILITY.
wenzelm@57452
  1186
  - No discriminators or selectors are generated by default by

    "sum.case").  INCOMPATIBILITY.
wenzelm@57452
  1195
  - The generated constants "xxx_case", "xxx_rec", and "xxx_size" have

  1271
wenzelm@57508
  1272
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1273
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1274
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1275
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1276
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1277
corresponding tactics; the old default can be restored using "declare
wenzelm@57508
  1278
[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508
  1279
wenzelm@57508
  1280
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
  1281
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1282
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1283
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1284
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1285
wenzelm@57508
  1286
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
  1287
(without requiring restart), instead of former settings variable
wenzelm@57508
  1288
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

wenzelm@57508
  1290
wenzelm@57508
  1291
* Sledgehammer:
wenzelm@57508
  1292
  - Z3 can now produce Isar proofs.
wenzelm@57508
  1293
  - MaSh overhaul:
blanchet@57532
  1294
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1295
      Python and increase performance and reliability.
wenzelm@57508
  1296
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1297
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  1298
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
  1299
      Options / Isabelle / General to "none".
wenzelm@57508
  1300
  - New option:
wenzelm@57508
  1301
      smt_proofs
wenzelm@57508
  1302
  - Renamed options:
wenzelm@57508

INCOMPATIBILITY.
wenzelm@57508
  1307
wenzelm@57508
  1308
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
  1309
wenzelm@57508
  1310
* Nitpick:
wenzelm@57508
  1311
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  1312
    take infinite values.
wenzelm@57508
  1313
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
  1314
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  1315
  - Removed "std" option.
wenzelm@57508
  1316
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
  1317
    "hide_types".
wenzelm@57508
  1318
wenzelm@57508
  1319
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
  1320
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
  1321
wenzelm@57508
  1322
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
  1323
wenzelm@57508
  1324
* Adjustion of INF and SUP operations:
wenzelm@57508
  1325
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
  1326
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  1327
    SUP instead uniformly.
wenzelm@57508
  1328
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  1329
    or SUP and Sup.
wenzelm@57508
  1330
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  1331
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  1332
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
  1333
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508
  1334
    INT_cong, SUP_cong

* The signature and semantics of Document.Snapshot.cumulate_markup /
wenzelm@55622
  1866
select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622
  1867
order of reports given by the prover: later markup is usually more
wenzelm@55622
  1868

wenzelm@54449
  1876
wenzelm@57504
  1877
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  1878
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  1879
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  1880
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  1881
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  1882
appropriate than Thm.eq_thm.
wenzelm@57504
  1883
wenzelm@57504
  1884
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504

rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  1886
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  1887
actually belongs to it).
wenzelm@57504
  1888
wenzelm@57504
  1889
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  1890
variables that are meant to become schematic need to be given as
wenzelm@57504
  1891
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  1892
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  1893
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  1894
of schematic variables.

wenzelm@56303
  1898
wenzelm@56279
  1899
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452

INCOMPATIBILITY.
wenzelm@56281
  1905
wenzelm@56281
  1906
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  1907
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  1908
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  1909
INCOMPATIBILITY.
wenzelm@56279
  1910
wenzelm@54449
  1911
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  1912
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  1913
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  1914
formal context.
wenzelm@54449
  1915
wenzelm@56205
  1916
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  1917
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  1918
wenzelm@56071
  1919
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  1920
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  1921
wenzelm@56135
  1922
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  1923
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1924
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1925
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  1926
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  1927
wenzelm@56399
  1928
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399

  1930
purposes.

wenzelm@57504
  1936
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  1937
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  1938
the "system" manual provides general explanations about add-on
wenzelm@57504
  1939
components, especially those that are not bundled with the release.
wenzelm@57443
  1940
wenzelm@56439
  1941
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  1942
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  1943
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  1944
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  1945
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  1946
settings variable.
wenzelm@56439
  1947
wenzelm@57439
  1948
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1949
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1950
obsolete Isar TTY loop.
wenzelm@57439
  1951
wenzelm@57452
  1952
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1953
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1954
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1955
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1956
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1957
wenzelm@57413
  1958
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1959
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1960
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1961
wenzelm@57452
  1962
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1963
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1964
wenzelm@57452
  1965
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1966
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1967
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1968
wenzelm@57452
  1969
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1970
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1971
files are copied to the document output directory, before document

  1972
processing is started.
wenzelm@57452
  1973
wenzelm@57504
  1974

  2021
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  2022

wenzelm@53016
  2023
for consts or fixed variables may be used as fall-back for unusual

  2027
The ML reference variable "legacy_isub_isup" may be set as temporary

wenzelm@52487
  2036
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  2037
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  2038
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  2039

wenzelm@52060
  2042
wenzelm@52430
  2043
* Proper diagnostic command 'print_state'.  Old 'pr' (with its

wenzelm@52549
  2047
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549

wenzelm@54319
  2090
wenzelm@54305
  2091
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  2092
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  2093
wenzelm@53971
  2094
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971

wenzelm@53971
  2096
such command executions while editing.
wenzelm@53271
  2097
wenzelm@53971
  2098

wenzelm@53971
  2100
wenzelm@53971
  2101
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  2102
toplevel theorem statements.
wenzelm@53971
  2103
wenzelm@53971

* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  2105
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  2106
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365

ballarin@54049
  2122
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  2123
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  2124
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  2125
light-weight alternative to 'sublocale'.  See "isar-ref" manual for

details.
haftmann@51747

  2128
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  2129
wenzelm@51313
  2130
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313

  2135
INCOMPATIBILITY.
wenzelm@51316
  2136
wenzelm@53971

* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  2138
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  2139
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  2140
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  2141
wenzelm@53971
  2142
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  2143
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  2144
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  2145
wenzelm@53971

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

  2158
INCOMPATIBILITY.
wenzelm@54032
  2159
wenzelm@54032

* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  2161
wenzelm@54032
  2162
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  2163
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  2164
from the datatype package. The declaration attribute
wenzelm@54032
  2165
"case_translation" can be used to register new case combinators:
wenzelm@54032
  2166
wenzelm@54032
  2167
  declare [[case_translation case_combinator constructor1 ... constructorN]]

* Code generator:
wenzelm@53160
  2170
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  2171
    'code_instance'.
wenzelm@53160
  2172
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  2173
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  2174
wenzelm@53983

See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  2176
examples.
haftmann@52435
  2177
wenzelm@54032
  2178
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  2179
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  2180
to distinguish both when desired.
wenzelm@54032
  2181
wenzelm@54032
  2182
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  2183
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  2184
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code

wenzelm@54032
  2186
wenzelm@54032
  2187
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  2188
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  2189
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  2190
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  2191
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  2192
ML).  INCOMPATIBILITY.
wenzelm@54032
  2193
wenzelm@54032
  2194
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  2195
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  2196
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  2197
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  2198
wenzelm@54032
  2199
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  2200
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  2201
wenzelm@54032
  2202
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  2203
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  2204
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
  2205
kuncar@54021
  2206
* Lifting:
kuncar@54021
  2207
  - parametrized correspondence relations are now supported:
wenzelm@54378
  2208
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  2209
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  2210
      transfer rules
kuncar@54021
  2211
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  2212
      correspondence relation can be generated
kuncar@54021
  2213
    + various new properties of the relator must be specified to support
kuncar@54021
  2214
      parametricity
kuncar@54021
  2215
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  2216
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  2217
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  2218
    copies
kuncar@54021
  2219
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  2220
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  2221
    anonymous context)
wenzelm@54378
  2222
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  2223
    Main. Potential INCOMPATIBILITY
kuncar@54021
  2224
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  2225
    lifting_forget, lifting_update
wenzelm@54378
  2226
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  2227
    INCOMPATIBILITY
kuncar@54021
  2228
kuncar@54021
  2229
* Transfer:
wenzelm@54378
  2230
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  2231
    by the actual invariant in a transferred goal
kuncar@54021
  2232
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  2233
  - Experimental support for transferring from the raw level to the
kuncar@54021
  2234
    abstract level: Transfer.transferred attribute
kuncar@54021
  2235
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  2236
haftmann@52286
  2237
* Reification and reflection:
wenzelm@53160
  2238
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  2239
    "Reification".
wenzelm@53160
  2240
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  2241
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  2242
INCOMPATIBILITY.
haftmann@52286
  2243
haftmann@51489
  2244
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  2245
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  2246
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  2247
    This is now identity on infinite sets.
wenzelm@52745
  2248
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  2249
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  2250
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  2251
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  2252
    See theory Big_Operators for canonical examples.
haftmann@51489
  2253
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  2254
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  2255
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  2256
    those foundational constants as substitutes, but it is
wenzelm@53983
  2257
    preferable to interpret the above locales accordingly.
haftmann@51489
  2258
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  2259
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  2260
  - Fact renames:
haftmann@51489
  2261
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  2262
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  2263
INCOMPATIBILITY.
haftmann@51489
  2264
haftmann@51487
  2265
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  2266
wenzelm@53526
  2267
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  2268
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  2269
class predicate assumption or sort constraint when possible.
Andreas@53362
  2270
INCOMPATIBILITY.
Andreas@53362
  2271
wenzelm@53160
  2272
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  2273
complete lattice but does not assume the existence of the top and
wenzelm@53160
  2274
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  2275
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  2276
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  2277
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  2278
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  2279
lemmas.
wenzelm@53160
  2280
wenzelm@53160
  2281
* Introduce type class linear_continuum as combination of
wenzelm@53160
  2282
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  2283
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  2284
wenzelm@53983
  2285
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  2286
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  2287
Rename bot -> order_bot, top -> order_top
lammich@53683
  2288
wenzelm@53160
  2289
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  2290
top and bottom elements.
hoelzl@51732
  2291
hoelzl@51732
  2292
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  2293
hoelzl@51732
  2294
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  2295
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  2296
wenzelm@53983
  2297
 - Introduce type class (lin)order_topology and
wenzelm@53983
  2298
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  2299
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  2300
hoelzl@51732
  2301
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  2302
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  2303
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  2304
wenzelm@53983
  2305
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  2306
   arbitrary filter.
wenzelm@53983
  2307
wenzelm@53983
  2308
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  2309
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  2310
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  2311
   continuous function is continuous, when the function is continuous
wenzelm@53983
  2312
   on a compact set.
hoelzl@51732
  2313
hoelzl@51732
  2314
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  2315
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  2316
   linear_continuum_topology).
hoelzl@51732
  2317
hoelzl@51732
  2318
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  2319
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  2320
   on all sequences converging to x.
wenzelm@53983
  2321
wenzelm@53983
  2322
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  2323
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  2324
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  2325
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  2326
   left or right.
hoelzl@51732
  2327
hoelzl@51732
  2328
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  2329
hoelzl@51732
  2330
     F within X = inf F (principal X)
hoelzl@51732
  2331
hoelzl@51732
  2332
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  2333
   abbreviation for "at x within UNIV"
hoelzl@51732
  2334
wenzelm@53983
  2335
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  2336
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  2337
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  2338
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  2339
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  2340
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  2341
hoelzl@51732
  2342
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  2343
hoelzl@51732
  2344
   + Moved RealDef and RComplete into Real
hoelzl@51732
  2345
hoelzl@51732
  2346
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  2347
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  2348
hoelzl@51732
  2349
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  2350
wenzelm@53983
  2351
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  2352
     Real_Vector_Spaces, and Limits
hoelzl@51732
  2353
hoelzl@51732
  2354
   + Moved Ln and Log to Transcendental
hoelzl@51732
  2355
hoelzl@51732
  2356
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  2357
hoelzl@51732
  2358
 - Remove various auxiliary lemmas.
hoelzl@51732
  2359

wenzelm@53971
  2438
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  2439
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971

Minor INCOMPATIBILITY.
wenzelm@51703
  2460
wenzelm@51717
  2461
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
  2462
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
  2463
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
  2464
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
  2465
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
  2466
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
  2467
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
  2468
wenzelm@53971
  2469
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  2470
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
  2471
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
  2472
clasets separately from the context.
wenzelm@53971
  2473
wenzelm@51717
  2474
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.

INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
  2476

wenzelm@52116
  2501
wenzelm@52439
  2502
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439

  2505
wenzelm@53971
  2506
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971

wenzelm@53971
  2508
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
  2509
tendency towards erratic fluctuation of URLs) has been discontinued.

wenzelm@50126
  2520
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  2521
no longer printed by default, since it is incompatible with
wenzelm@50126
  2522
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  2523
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  2524
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  2525
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  2526
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  2527
wenzelm@49699
  2528
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  2529
into the printed representation of formal entities --- notably type
wenzelm@49699
  2530
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  2531
information via tooltips in the output window, for example.
wenzelm@49699
  2532
wenzelm@48890
  2533
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  2534
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  2535
wenzelm@49243
  2536
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  2537
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  2538
Tools that load their additional source files may imitate the
wenzelm@49243
  2539
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  2540
dependencies properly.
wenzelm@49243
  2541
wenzelm@47967
  2542
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  2543
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  2544
wenzelm@50110
  2545
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  2546
remaining material in old "ref" manual.
wenzelm@48120
  2547
wenzelm@51050
  2548
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  2549
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  2550
and "class ... context ...".
wenzelm@49841
  2551
wenzelm@50772
  2552
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  2553
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  2554
the target context.  This form of declaration is stable when exported
wenzelm@50772
  2555
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  2556
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  2557
in HOL/inductive and HOL/function.
wenzelm@50772
  2558
wenzelm@49869
  2559
* More informative error messages for Isar proof commands involving
wenzelm@49869
  2560
lazy enumerations (method applications etc.).
wenzelm@49869
  2561
wenzelm@50213
  2562
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  2563
to name patterns (with clickable results).

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  2567
wenzelm@49968
  2568
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  2569
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  2570
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  2571
surface, while the prover is still crunching on internal
wenzelm@49968
  2572
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  2573
required to complete full proof checking eventually.
wenzelm@49968
  2574
wenzelm@49968
  2575
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  2576
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  2577
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  2578
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  2579
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  2580
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  2581
wenzelm@50717
  2582
* Improved support for commands that produce graph output: the text
wenzelm@50717
  2583
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  2584
browser on demand.
wenzelm@50717
  2585
wenzelm@49968
  2586
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  2587
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  2588
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  2589
that frequently occur in user interaction.
wenzelm@49968
  2590
wenzelm@49968
  2591
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  2592
files.  More scalable management of formal document content.
wenzelm@49968
  2593
wenzelm@50505
  2594
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  2595
certain number of messages per command transaction, with some user
wenzelm@50505
  2596
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  2597
potentially infinite message streams.
wenzelm@49968
  2598
wenzelm@49968
  2599
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  2600
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  2601
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  2602
schemes.
wenzelm@49968
  2603
wenzelm@50184
  2604
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  2605
symbols.
wenzelm@50184
  2606
wenzelm@51082
  2607
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  2608
continuous display of the chart slows down the system.
wenzelm@50701
  2609
wenzelm@50183
  2610
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  2611
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  2612
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  2613
wenzelm@50198
  2614
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  2615
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  2616
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  2617
need to be adapted to local keyboard layouts.
wenzelm@50183
  2618
wenzelm@50730
  2619
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  2620
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  2621
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  2622
wenzelm@50406
  2623
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  2624
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  2625
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  2626

wenzelm@50406
  2627
wenzelm@49968
  2628
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates

  2636
Haskell Prelude to a small set of fundamental operations.

* Command 'export_code': relative file names are interpreted
wenzelm@50646
  2639
relatively to master directory of current theory rather than the
wenzelm@50646
  2640
rather arbitrary current working directory.  INCOMPATIBILITY.

* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  2643
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  2644
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  2645
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  2646
with some care where this is really required.
wenzelm@48205
  2647
wenzelm@48792
  2648
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  2649
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  2650
given sort.  Example (in HOL):
wenzelm@48792
  2651
wenzelm@48792
  2652
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
  2653
wenzelm@50716
  2654
* Command 'locale_deps' visualizes all locales and their relations as
wenzelm@50716
  2655
a Hasse diagram.

* Sledgehammer:
wenzelm@50646
  2661
wenzelm@50646
  2662
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
  2663
    Sledgehammer manual for details.
wenzelm@50646
  2664
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
  2665
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
  2666
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
  2667
  - Renamed options:
wenzelm@50646
  2668
      isar_proof ~> isar_proofs
wenzelm@50646
  2669
      isar_shrink_factor ~> isar_shrink
wenzelm@50646
  2670
      max_relevant ~> max_facts
wenzelm@50646
  2671
      relevance_thresholds ~> fact_thresholds
wenzelm@50646
  2672

  2673
* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
  2674
switched on by default, and can be switched off by setting the
wenzelm@50646
  2675
configuration quickcheck_optimise_equality to false.

INCOMPATIBILITY.
kuncar@50878
  2679
kuncar@50878
  2680
* Lifting:
kuncar@50878
  2681
  - generation of an abstraction function equation in lift_definition
kuncar@50878
  2682
  - quot_del attribute
kuncar@50878
  2683
  - renamed no_abs_code -> no_code (INCOMPATIBILITY.)

* Simproc "finite_Collect" rewrites set comprehensions into pointfree
wenzelm@50646
  2686
expressions.
wenzelm@50646
  2687
wenzelm@50646
  2688
* Preprocessing of the code generator rewrites set comprehensions into
wenzelm@50646
  2689
pointfree expressions.

  2691
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
  2692
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
  2693
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
  2694
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
  2695
INCOMPATIBILITY.
haftmann@49948
  2696
wenzelm@49836
  2697
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  2698
set definition and alternative name have been discontinued.  The
wenzelm@49836
  2699
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
  2700
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
  2701
accordingly.
wenzelm@49836
  2702
wenzelm@50646
  2703
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
  2704
directly.  INCOMPATIBILITY.
wenzelm@50646
  2705
wenzelm@50646
  2706
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
  2707
List.  INCOMPATIBILITY.
haftmann@49822
  2708
haftmann@49739
  2709
* Theorem UN_o generalized to SUP_comp.  INCOMPATIBILITY.
haftmann@49739
  2710
haftmann@49738
  2711
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
  2712
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
  2713
wenzelm@50646
  2714
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
  2715
wenzelm@50646
  2716
* Theory "Transitive_Closure": renamed lemmas
wenzelm@50646
  2717
wenzelm@50646
  2718
  reflcl_tranclp -> reflclp_tranclp
wenzelm@50646
  2719
  rtranclp_reflcl -> rtranclp_reflclp
wenzelm@50646
  2720
wenzelm@50646
  2721
INCOMPATIBILITY.
wenzelm@50646
  2722
wenzelm@50646
  2723
* Theory "Rings": renamed lemmas (in class semiring)
wenzelm@50646
  2724
wenzelm@50646
  2725
  left_distrib ~> distrib_right
wenzelm@50646
  2726
  right_distrib ~> distrib_left
wenzelm@50646
  2727
wenzelm@50646
  2728
INCOMPATIBILITY.
wenzelm@50646
  2729
wenzelm@50646
  2730
* Generalized the definition of limits:
