New in this Isabelle version
wenzelm@50994

----------------------------
wenzelm@50994

wenzelm@51293
     7
*** General ***
wenzelm@51293
     8
wenzelm@52487
     9
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
    10
"isabelle options"), configuration option within the context (see also
wenzelm@52487
    11
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
    12
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
    13
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
    14
wenzelm@52060
    15
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
    16
INCOMPATIBILITY.
wenzelm@52060
    17
wenzelm@51417
    18
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@51417
    19
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@51417
    20
tree-like organization via implicit sub-session relation, with its
wenzelm@51417
    21
tendency towards erratic fluctuation of URLs, has been discontinued.
wenzelm@51417
    22
The default chapter is "Unsorted".  Potential INCOMPATIBILITY for HTML
wenzelm@51417
    23
presentation of theories.
wenzelm@51417
    24
wenzelm@51293
    25
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@51293
    26
commands like 'ML_file' work without separate declaration of file
wenzelm@51293
    27
dependencies.  Minor INCOMPATIBILITY.
wenzelm@51293
    28
wenzelm@51295
    29
* Discontinued redundant 'use' command, which was superseded by
wenzelm@51295
    30
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@51295
    31
wenzelm@52415
    32
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@52415
    33
eliminated old "ref" manual.
wenzelm@52415
    34
wenzelm@52430
    35
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
    36
implicit change of some global references) is retained for now as
wenzelm@52430
    37
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
    38
wenzelm@52549
    39
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
    40
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
    41
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
    42
wenzelm@51293
    43
wenzelm@51533
    44
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
    45
wenzelm@52818
    46
* Improved "Theories" panel: Continuous checking of proof document
wenzelm@52818
    47
(visible and required parts) may be controlled explicitly, using check
wenzelm@52818
    48
box or shortcut "C+e ENTER".  Individual theory nodes may be marked
wenzelm@52818
    49
explicitly as required and checked in full, using check box or
wenzelm@52818
    50
shortcut "C+e SPACE".
wenzelm@52779
    51
wenzelm@52646
    52
* Strictly monotonic document update, without premature cancelation of
wenzelm@52646
    53
running transactions that are still needed: avoid reset/restart of
wenzelm@52646
    54
such command executions while editing.
wenzelm@52646
    55
wenzelm@52646
    56
* Support for asynchronous print functions, as overlay to existing
wenzelm@52646
    57
document content.
wenzelm@52646
    58
wenzelm@52646
    59
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@52646
    60
toplevel theorem statements.
wenzelm@52646
    61
wenzelm@52445
    62
* Dockable window "Documentation" provides access to Isabelle
wenzelm@52445
    63
documentation.
wenzelm@52445
    64
wenzelm@51533
    65
* Dockable window "Timing" provides an overview of relevant command
wenzelm@51533
    66
timing information.
wenzelm@51533
    67
wenzelm@51553
    68
* Option to skip over proofs, using implicit 'sorry' internally.
wenzelm@51553
    69
wenzelm@51533
    70
wenzelm@51313
    71
*** Pure ***
wenzelm@51313
    72
wenzelm@52788
    73
* Type theory is now immutable, without any special treatment of
wenzelm@52788
    74
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@52788
    75
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@52788
    76
Theory.checkpoint, and the auxiliary type theory_ref.  Minor
wenzelm@52788
    77
INCOMPATIBILITY.
wenzelm@52788
    78
wenzelm@52488
    79
* System option "proofs" has been discontinued.  Instead the global
wenzelm@52488
    80
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@52488
    81
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@52488
    82
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@52488
    83
wenzelm@52143
    84
* Syntax translation functions (print_translation etc.) always depend
wenzelm@52143
    85
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@52143
    86
now the default.  Minor INCOMPATIBILITY.
wenzelm@52143
    87
haftmann@51747
    88
* Target-sensitive commands 'interpretation' and 'sublocale'.
haftmann@51747
    89
Particulary, 'interpretation' now allows for non-persistent
haftmann@51747
    90
interpretation within "context ... begin ... end" blocks.
haftmann@51747
    91
See "isar-ref" manual for details.
haftmann@51747
    92
ballarin@51565
    93
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
    94
wenzelm@51313
    95
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
    96
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
    97
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
    98
wenzelm@51316
    99
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
   100
INCOMPATIBILITY.
wenzelm@51316
   101
wenzelm@52463
   102
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
   103
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
   104
situations.
wenzelm@52463
   105
wenzelm@51313
   106
hoelzl@51002
   107
*** HOL ***
hoelzl@51002
   108
wenzelm@52896
   109
* Improved support for adhoc overloading of constants (see also
wenzelm@52896
   110
isar-ref manual and ~~/src/HOL/ex/Adhoc_Overloading_Examples.thy).
wenzelm@52896
   111
haftmann@52637
   112
* Attibute 'code': 'code' now declares concrete and abstract code equations uniformly.
haftmann@52637
   113
Use explicit 'code equation' and 'code abstract' to distinguish both when desired.
haftmann@52637
   114
haftmann@52435
   115
* Code generator:
haftmann@52435
   116
  * 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' / 'code_instance'.
haftmann@52435
   117
  * 'code_identifier' declares name hints for arbitrary identifiers in generated code,
haftmann@52435
   118
    subsuming 'code_modulename'.
haftmann@52435
   119
  See the Isar reference manual for syntax diagrams, and the HOL theories for examples.
haftmann@52435
   120
haftmann@52380
   121
* Library/Polynomial.thy:
haftmann@52380
   122
  * Use lifting for primitive definitions.
haftmann@52380
   123
  * Explicit conversions from and to lists of coefficients, used for generated code.
haftmann@52380
   124
  * Replaced recursion operator poly_rec by fold_coeffs.
haftmann@52380
   125
  * Prefer pre-existing gcd operation for gcd.
haftmann@52380
   126
  * Fact renames:
haftmann@52380
   127
    poly_eq_iff ~> poly_eq_poly_eq_iff
haftmann@52380
   128
    poly_ext ~> poly_eqI
haftmann@52380
   129
    expand_poly_eq ~> poly_eq_iff
haftmann@52380
   130
IMCOMPATIBILTIY.
haftmann@52380
   131
haftmann@52286
   132
* Reification and reflection:
haftmann@52286
   133
  * Reification is now directly available in HOL-Main in structure "Reification".
haftmann@52286
   134
  * Reflection now handles multiple lists with variables also.
haftmann@52286
   135
  * The whole reflection stack has been decomposed into conversions.
haftmann@52286
   136
INCOMPATIBILITY.
haftmann@52286
   137
haftmann@52141
   138
* Weaker precendence of syntax for big intersection and union on sets,
haftmann@52141
   139
in accordance with corresponding lattice operations.  INCOMPATIBILITY.
haftmann@52141
   140
traytel@51682
   141
* Nested case expressions are now translated in a separate check
traytel@51682
   142
  phase rather than during parsing. The data for case combinators
traytel@51682
   143
  is separated from the datatype package. The declaration attribute
traytel@51682
   144
  "case_translation" can be used to register new case combinators:
traytel@51682
   145
traytel@51682
   146
  declare [[case_translation case_combinator constructor1 ... constructorN]]
traytel@51682
   147
wenzelm@51596
   148
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@51596
   149
haftmann@51489
   150
* Revised devices for recursive definitions over finite sets:
haftmann@51489
   151
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
   152
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
   153
    This is now identity on infinite sets.
wenzelm@52745
   154
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
   155
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
   156
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
   157
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
   158
    See theory Big_Operators for canonical examples.
haftmann@51489
   159
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
   160
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
   161
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
   162
    those foundational constants as substitutes, but it is
haftmann@51489
   163
    preferable to interpret the above locales accordingly. 
haftmann@51489
   164
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
   165
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
   166
  - Fact renames:
haftmann@51489
   167
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
   168
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
   169
haftmann@51489
   170
INCOMPATIBILITY.
haftmann@51489
   171
haftmann@51487
   172
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
   173
haftmann@51382
   174
* Discontinued theory src/HOL/Library/Eval_Witness.
haftmann@51382
   175
INCOMPATIBILITY.
haftmann@51382
   176
wenzelm@51238
   177
* Discontinued obsolete src/HOL/IsaMakefile (considered legacy since
wenzelm@51238
   178
Isabelle2013).  Use "isabelle build" to operate on Isabelle sessions.
wenzelm@51238
   179
haftmann@51168
   180
* Numeric types mapped by default to target language numerals:
haftmann@51168
   181
natural (replaces former code_numeral) and integer (replaces
haftmann@51168
   182
former code_int).  Conversions are available as integer_of_natural /
haftmann@51168
   183
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
haftmann@51168
   184
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in ML).
haftmann@51168
   185
INCOMPATIBILITY.
haftmann@51168
   186
haftmann@51168
   187
* Discontinued theories Code_Integer and Efficient_Nat by a more
haftmann@51168
   188
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
haftmann@51168
   189
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on
haftmann@51168
   190
code generation for details.  INCOMPATIBILITY.
haftmann@51168
   191
hoelzl@51773
   192
* Introduce type class "conditionally_complete_lattice": Like a complete
hoelzl@51732
   193
  lattice but does not assume the existence of the top and bottom elements.
hoelzl@51732
   194
  Allows to generalize some lemmas about reals and extended reals.
hoelzl@51732
   195
  Removed SupInf and replaced it by the instantiation of
hoelzl@51773
   196
  conditionally_complete_lattice for real. Renamed lemmas about
hoelzl@51773
   197
  conditionally-complete lattice from Sup_... to cSup_... and from Inf_...
hoelzl@51773
   198
  to cInf_... to avoid hidding of similar complete lattice lemmas.
hoelzl@51775
   199
hoelzl@51775
   200
  Introduce type class linear_continuum as combination of conditionally-complete
hoelzl@51775
   201
  lattices and inner dense linorders which have more than one element.
hoelzl@51732
   202
INCOMPATIBILITY.
hoelzl@51732
   203
hoelzl@51732
   204
* Introduce type classes "no_top" and "no_bot" for orderings without top
hoelzl@51732
   205
  and bottom elements.
hoelzl@51732
   206
hoelzl@51732
   207
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
   208
hoelzl@51732
   209
* Complex_Main: Unify and move various concepts from
hoelzl@51732
   210
  HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
   211
hoelzl@51775
   212
 - Introduce type class (lin)order_topology and linear_continuum_topology.
hoelzl@51775
   213
   Allows to generalize theorems about limits and order.
hoelzl@51775
   214
   Instances are reals and extended reals.
hoelzl@51732
   215
hoelzl@51732
   216
 - continuous and continuos_on from Multivariate_Analysis:
hoelzl@51732
   217
   "continuous" is the continuity of a function at a filter.
hoelzl@51732
   218
   "isCont" is now an abbrevitation: "isCont x f == continuous (at _) f".
hoelzl@51732
   219
hoelzl@51732
   220
   Generalized continuity lemmas from isCont to continuous on an arbitrary
hoelzl@51732
   221
   filter.
hoelzl@51732
   222
hoelzl@51732
   223
 - compact from Multivariate_Analysis. Use Bolzano's lemma
hoelzl@51732
   224
   to prove compactness of closed intervals on reals. Continuous functions
hoelzl@51732
   225
   attain infimum and supremum on compact sets. The inverse of a continuous
hoelzl@51732
   226
   function is continuous, when the function is continuous on a compact set.
hoelzl@51732
   227
hoelzl@51732
   228
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
   229
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
   230
   linear_continuum_topology).
hoelzl@51732
   231
hoelzl@51732
   232
 - first_countable_topology from Multivariate_Analysis. Is used to
hoelzl@51732
   233
   show equivalence of properties on the neighbourhood filter of x and on
hoelzl@51732
   234
   all sequences converging to x.
hoelzl@51732
   235
hoelzl@51732
   236
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved theorems
hoelzl@51732
   237
   from Library/FDERIV.thy to Deriv.thy and base the definition of DERIV on
hoelzl@51732
   238
   FDERIV. Add variants of DERIV and FDERIV which are restricted to sets,
hoelzl@51732
   239
   i.e. to represent derivatives from left or right.
hoelzl@51732
   240
hoelzl@51732
   241
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
   242
hoelzl@51732
   243
     F within X = inf F (principal X)
hoelzl@51732
   244
hoelzl@51732
   245
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
   246
   abbreviation for "at x within UNIV"
hoelzl@51732
   247
hoelzl@51732
   248
 - Introduce named theorem collections tendsto_intros, continuous_intros,
hoelzl@51732
   249
   continuous_on_intros and FDERIV_intros. Theorems in tendsto_intros (or
hoelzl@51732
   250
   FDERIV_intros) are also available as tendsto_eq_intros (or
hoelzl@51732
   251
   FDERIV_eq_intros) where the right-hand side is replaced by a congruence
hoelzl@51732
   252
   rule. This allows to apply them as intro rules and then proving
hoelzl@51732
   253
   equivalence by the simplifier.
hoelzl@51732
   254
hoelzl@51732
   255
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
   256
hoelzl@51732
   257
   + Moved RealDef and RComplete into Real
hoelzl@51732
   258
hoelzl@51732
   259
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
   260
     topological spaces, filters, limits and continuity to it
hoelzl@51732
   261
hoelzl@51732
   262
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
   263
hoelzl@51732
   264
   + Split Lim, SEQ, Series into Topological_Spaces, Real_Vector_Spaces, and
hoelzl@51732
   265
     Limits
hoelzl@51732
   266
hoelzl@51732
   267
   + Moved Ln and Log to Transcendental
hoelzl@51732
   268
hoelzl@51732
   269
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732

  With HOL-Spec_Check, ML developers can check specifications with the

wenzelm@51686
   312
wenzelm@51703
   313
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@51703
   314
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@51703

* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
   319
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
   320
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
   321
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
   322
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port

* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
   363
no longer printed by default, since it is incompatible with
wenzelm@50126
   364
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
   365
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
   366
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
   367
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
   368
accessible theorems in the theory context are finished (as before).
wenzelm@50126
   369
wenzelm@49699
   370
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
   371
into the printed representation of formal entities --- notably type
wenzelm@49699
   372
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
   373
information via tooltips in the output window, for example.
wenzelm@49699
   374
wenzelm@48890
   375
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
   376
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
   377
wenzelm@49243
   378
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
   379
theory header are legacy features and will be discontinued soon.
wenzelm@49243
   380
Tools that load their additional source files may imitate the
wenzelm@49243
   381
'ML_file' implementation, such that the system can take care of
wenzelm@49243
   382
dependencies properly.
wenzelm@49243
   383
wenzelm@47967
   384
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
   385
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
   386
wenzelm@50110
   387
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
   388
remaining material in old "ref" manual.
wenzelm@48120
   389
wenzelm@51050
   390
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
   391
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
   392
and "class ... context ...".
wenzelm@49841
   393
wenzelm@50772
   394
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
   395
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
   396
the target context.  This form of declaration is stable when exported
wenzelm@50772
   397
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
   398
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
   399
in HOL/inductive and HOL/function.
wenzelm@50772
   400
wenzelm@49869
   401
* More informative error messages for Isar proof commands involving
wenzelm@49869
   402
lazy enumerations (method applications etc.).
wenzelm@49869
   403
wenzelm@50213
   404
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
   405

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
   409
wenzelm@49968
   410
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
   411
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
   412
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
   413
surface, while the prover is still crunching on internal
wenzelm@49968
   414
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
   415
required to complete full proof checking eventually.
wenzelm@49968
   416
wenzelm@49968
   417
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
   418
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
   419
tooltips leads to some window that supports the same recursively,
wenzelm@49968
   420
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
   421
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
   422
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
   423
wenzelm@50717
   424
* Improved support for commands that produce graph output: the text
wenzelm@50717
   425
message contains a clickable area to open a new instance of the graph
wenzelm@50717
   426
browser on demand.
wenzelm@50717
   427
wenzelm@49968
   428
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
   429
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
   430
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
   431
that frequently occur in user interaction.
wenzelm@49968
   432
wenzelm@49968
   433
* More efficient painting and improved reactivity when editing large
wenzelm@49968
   434
files.  More scalable management of formal document content.
wenzelm@49968
   435
wenzelm@50505
   436
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
   437
certain number of messages per command transaction, with some user
wenzelm@50505
   438
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
   439
potentially infinite message streams.
wenzelm@49968
   440
wenzelm@49968
   441
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
   442
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
   443
options, including tuning parameters for editor reactivity and color
wenzelm@49968
   444
schemes.
wenzelm@49968
   445
wenzelm@50184
   446
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
   447
symbols.
wenzelm@50184
   448
wenzelm@51082
   449
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
   450
continuous display of the chart slows down the system.
wenzelm@50701
   451
wenzelm@50183
   452
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
   453
bold, reset of style -- operating on single symbols or text
wenzelm@50198
   454
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
   455
wenzelm@50198
   456
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
   457
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
   458
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
   459
need to be adapted to local keyboard layouts.
wenzelm@50183
   460
wenzelm@50730
   461
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
   462
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730

demand, without bundling big platform-dependent heap images in the
wenzelm@50406
   468

wenzelm@49968

* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates

wenzelm@48205
   485
use regular rule composition via "OF" / "THEN", or explicit proof

structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
   487
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
   488
with some care where this is really required.
wenzelm@48205
   489
wenzelm@48792

* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
   491
constraint, to infer and check the most general type conforming to a
wenzelm@51063
   492
given sort.  Example (in HOL):

  typ "_ * _ * bool * unit" :: finite
wenzelm@48792

haftmann@49388
   554
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
   555
wenzelm@50646
   556
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646

INCOMPATIBILITY.
wenzelm@50646
   571
wenzelm@50646
   572
* Generalized the definition of limits:
wenzelm@50646
   573
wenzelm@50646
   574
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
   575
    expresses that when the input values x converge to F then the
wenzelm@50646
   576
    output f x converges to G.
wenzelm@50646
   577
wenzelm@50646
   578
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
   579
    infinity (at_bot).
wenzelm@50646
   580
wenzelm@50646
   581
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
   582
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
   583
wenzelm@50646
   584
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
   585
    at_top".
wenzelm@50646

wenzelm@50646
   587
INCOMPATIBILITY.
wenzelm@50646
   588
wenzelm@50646
   589
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
   590
lattice type classes.
wenzelm@50646
   591
wenzelm@50646
   592
* Theory "Library/Multiset": renamed
wenzelm@50646

INCOMPATIBILITY.
wenzelm@50646
   598
wenzelm@50646
   599
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
   600
changes as follows.
wenzelm@50646
   601
wenzelm@50646
   602
  - Renamed constants (and related lemmas)
Christian@49145
   603
Christian@49145
   604
      prefix ~> prefixeq
Christian@49145
   605
      strict_prefix ~> prefix
Christian@49145
   606
wenzelm@50646
   607
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
   608
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
   609
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
   610
    Renamed lemmas accordingly.
wenzelm@50646
   611
wenzelm@50646
   612
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
   613
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
   614
    "list_hembeq (op =)".
wenzelm@50646
   615
wenzelm@50646
   616
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
   617
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
   618
    interpretations). The type class instances are now in theory
wenzelm@50646
   619
    Library/Prefix_Order.
wenzelm@50646
   620
wenzelm@50646
   621
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
   622
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516
   623
Christian@50516

wenzelm@50646
   642
wenzelm@50646
   643
* New theory Library/Countable_Set.
wenzelm@50646
   644
wenzelm@50646
   645
* Theory Library/Debug and Library/Parallel provide debugging and
wenzelm@50646
   646
parallel execution for code generated towards Isabelle/ML.
wenzelm@50646
   647
wenzelm@50646
   648
* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
   649
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
   650
extensional_funcset by an abbreviation, and renamed lemmas from
wenzelm@50646
   651
extensional_funcset to PiE as follows:

wenzelm@50646
   664
INCOMPATIBILITY.
wenzelm@50646
   665
wenzelm@50646
   666
* Theory Library/FinFun: theory of almost everywhere constant
wenzelm@50646
   667
functions (supersedes the AFP entry "Code Generation for Functions as
wenzelm@50646
   668
Data").
wenzelm@50646
   669
wenzelm@50646
   670
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
   671
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
   672
TYPE('a) as another parameter avoids unnecessary closures in generated
wenzelm@50646
   673
code.
wenzelm@50646
   674
wenzelm@50646
   675
* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646
   676
from sorted associative lists. Merging two trees with rbt_union may
wenzelm@50646
   677
return a structurally different tree than before.  Potential
wenzelm@50646
   678
INCOMPATIBILITY.
wenzelm@50646
   679
wenzelm@50646

wenzelm@50646
   685
wenzelm@50646
   686
  "basis :: 'a::euclidean_space => nat => real"
wenzelm@50646
   687
  "\<Chi>\<Chi> :: (nat => real) => 'a::euclidean_space"
wenzelm@50646
   688
wenzelm@50646
   689
on euclidean spaces by using the inner product "_ \<bullet> _" with
wenzelm@50646
   690
vectors from the Basis set: "\<Chi>\<Chi> i. f i" is superseded by
wenzelm@50646
   691
"SUM i : Basis. f i * r i".
wenzelm@50646
   692
wenzelm@50646
   693
  With this change the following constants are also changed or removed:
wenzelm@50646
   694
wenzelm@50646
   695
    DIM('a) :: nat  ~>  card (Basis :: 'a set)   (is an abbreviation)
wenzelm@50646
   696
    a $$ i  ~>  inner a i  (where i : Basis)
wenzelm@50646
   697
    cart_base i  removed
wenzelm@50646
   698
    \<pi>, \<pi>'  removed
hoelzl@50526

hoelzl@50526
   700
  Theorems about these constants where removed.
hoelzl@50526
   701
hoelzl@50526

   717
* HOL/Probability:
wenzelm@50646
   718
wenzelm@50646
   719
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
   720
wenzelm@50646
   721
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
   722
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
   723
    (borel_measurable_induct).
wenzelm@50646
   724
wenzelm@50646
   725
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a
wenzelm@50646
   726
    projective family).
wenzelm@50646
   727
wenzelm@50646

* HOL/Cardinals: Theories of ordinals and cardinals (supersedes the
wenzelm@50646
   729
AFP entry "Ordinals_and_Cardinals").
wenzelm@50646
   730
wenzelm@50646
   731
* HOL/BNF: New (co)datatype package based on bounded natural functors
wenzelm@50646
   732
with support for mixed, nested recursion and interesting non-free
wenzelm@50646
   733
datatypes.
blanchet@48094
   734
wenzelm@50991
   735
* HOL/Finite_Set and Relation: added new set and relation operations
kuncar@50878
   736
expressed by Finite_Set.fold.
kuncar@50878
   737
kuncar@50878
   738
* New theory HOL/Library/RBT_Set: implementation of sets by red-black
kuncar@50878
   739
trees for the code generator.
kuncar@50878
   740
kuncar@50878
   741
* HOL/Library/RBT and HOL/Library/Mapping have been converted to
kuncar@50878
   742
Lifting/Transfer.
kuncar@50878
   743
possible INCOMPATIBILITY.
kuncar@50878
   744

*** Document preparation ***
wenzelm@48206
   750
wenzelm@50646
   751
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
   752
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
   753
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
   754
wenzelm@50646
   755
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
   756
instead of slightly exotic babel/greek.
wenzelm@48206
   757
wenzelm@48616
   758
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
   759
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
   760
document/root.tex.
wenzelm@48616
   761
wenzelm@48657
   762
* Simplified custom document/build script, instead of old-style
wenzelm@48657
   763
document/IsaMakefile.  Minor INCOMPATIBILITY.
wenzelm@48657
   764
wenzelm@48206

wenzelm@48992
   766
*** ML ***
wenzelm@48992
   767
wenzelm@50646
   768
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
   769
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
   770
hardware and Poly/ML runtime system.
wenzelm@50646
   771
wenzelm@49869
   772
* Type Seq.results and related operations support embedded error
wenzelm@49869
   773
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
   774
informative errors in the absence of any usable results.
wenzelm@49869
   775
wenzelm@48992
   776
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
   777
formal device to inline positions into message text, but not
wenzelm@48992
   778
necessarily printing visible text.
wenzelm@48992

wenzelm@48206
   781
*** System ***
wenzelm@48206
   782
wenzelm@48585
   783
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
   784
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
   785
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
   786
session root directories for use with "isabelle build", similar to
wenzelm@51056
   787
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
   788
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
   789
mkdir / make are rendered obsolete.
wenzelm@48736
   790
wenzelm@51056
   791
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
   792
regular isabelle build tool.  For example:
wenzelm@51056
   793
wenzelm@51056
   794
  isabelle build -s -b HOL
wenzelm@51056
   795
wenzelm@48736
   796
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
   797
wenzelm@48722
   798
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
   799
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
   800
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
   801
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
   802
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
   803
wenzelm@48693
   804
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
   805
required for "isabelle build", for example.
wenzelm@48693
   806
wenzelm@50646
   807
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
   808
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
   809
wenzelm@50646
   810
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
   811
INCOMPATIBILITY.
wenzelm@50646
   812
wenzelm@48844
   813
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
   814
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
   815
version of Isabelle.
wenzelm@48844
   816
wenzelm@50646
   817
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
   818
platform family: "linux", "macos", "windows".
wenzelm@50646
   819
wenzelm@50646
   820
* The ML system is configured as regular component, and no longer
wenzelm@50646
   821
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
   822
for home-made settings.
wenzelm@50132
   823
wenzelm@50701
   824
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
   825
wenzelm@48206
   826
* Discontinued support for Poly/ML 5.2.1, which was the last version

* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
   831
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
   832
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
   833
settings manually, or use a Proof General version that has been
wenzelm@48574
   834
bundled as Isabelle component.

*** General ***
wenzelm@45593
   842
wenzelm@45614
   843
* Prover IDE (PIDE) improvements:
wenzelm@45614
   844
wenzelm@47585
   845
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
   846
    command-line needs to be typed into the source buffer)
wenzelm@45614
   847
  - markup for bound variables
wenzelm@47806
   848
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
   849
  - support for user-defined Isar commands within the running session
wenzelm@47158
   850
  - improved support for Unicode outside original 16bit range
wenzelm@47158
   851
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
   852
wenzelm@47806
   853
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
   854
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
   855
commands to be used in the same theory where defined.
wenzelm@46485
   856
wenzelm@47482
   857
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
   858
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
   859
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
   860
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
   861
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
   862
wenzelm@47482
   863
  context
wenzelm@47482
   864
    fixes x y z :: 'a
wenzelm@47482
   865
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
   866
  begin
wenzelm@47482
   867
wenzelm@47482
   868
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
   869
wenzelm@47482
   870
  end
wenzelm@47482
   871
wenzelm@47482
   872
  thm my_trans
wenzelm@47482
   873
wenzelm@47482
   874
The most basic application is to factor-out context elements of
wenzelm@47482
   875
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
   876
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
   877
wenzelm@47482
   878
Any other local theory specification element works within the "context
wenzelm@47482
   879
... begin ... end" block as well.
wenzelm@47482
   880
wenzelm@47484
   881
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
   882
given name in the context.  These may be later included in other
wenzelm@47484
   883
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
   884
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
   885
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
   886
wenzelm@47829
   887
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
   888
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
   889
old-style "standard" after instantiation or composition of facts
wenzelm@47829
   890
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
   891
indices of schematic variables.
wenzelm@47829
   892
wenzelm@47829
   893
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
   894
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
   895
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
   896
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
   897
etc. was exploited.
wenzelm@47829
   898
wenzelm@47829
   899
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
   900
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
   901
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
   902
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
   903
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
   904
of the material of that old tutorial.
wenzelm@47829
   905
wenzelm@47829
   906
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
   907
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
   908
manual.
wenzelm@47829
   909
wenzelm@47829
   910
wenzelm@47829
   911
*** Pure ***
wenzelm@47829
   912
wenzelm@46976
   913
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
   914
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
   915
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
   916
wenzelm@47855
   917
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
   918
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
   919
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
   920
undocumented feature.)
wenzelm@47855
   921
wenzelm@47856
   922
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
   923
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
   924
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
   925
wenzelm@47856
   926
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
   927
wenzelm@47856
   928
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
   929
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
   930
wenzelm@47856
   931
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
   932
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
   933
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
   934
order to accommodate newly introduced premises.)
wenzelm@47856
   935
wenzelm@47806
   936
* Renamed some inner syntax categories:
wenzelm@47806
   937
wenzelm@47806
   938
    num ~> num_token
wenzelm@47806
   939
    xnum ~> xnum_token
wenzelm@47806
   940
    xstr ~> str_token
wenzelm@47806
   941
wenzelm@47806
   942
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
   943
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
   944
position information via constraints).
wenzelm@47806
   945
wenzelm@47829
   946
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
   947
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
   948
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
   949
wenzelm@47856
   950
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
   951
in parse trees are always annotated by position constraints.
wenzelm@45134
   952
wenzelm@47464
   953
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
   954
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
   955
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
   956
wenzelm@47464
   957
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
   958
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
   959
wenzelm@47464
   960
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
   961
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
   962
haftmann@46028
   963
  definition [code_abbrev]: "f = t"
haftmann@46028
   964
haftmann@46028
   965
INCOMPATIBILITY.
wenzelm@45383
   966
wenzelm@47856
   967
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
   968
instead.  INCOMPATIBILITY.
wenzelm@47856
   969
wenzelm@47856
   970
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
   971
collection of foundational premises in the context (already marked as
wenzelm@47856
   972
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
   978
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
   979
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
   980
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
   981
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
   982
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
   983
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
   984
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
   985
possible.
wenzelm@47855
   986
wenzelm@47855
   987
For developments which deliberately mix predicates and sets, a
wenzelm@47464
   988
planning step is necessary to determine what should become a predicate
wenzelm@47464
   989
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
   990
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
   991
wenzelm@47855
   992
* Code generation by default implements sets as container type rather
wenzelm@47855
   993
than predicates.  INCOMPATIBILITY.
wenzelm@47855
   994
wenzelm@47855
   995
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
   996
wenzelm@47464
   997
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
   998
represents strictly positive binary numerals, along with functions
wenzelm@47464
   999
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  1000
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  1001
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  1002
user theories may require adaptations as follows:
huffman@47108
  1003
huffman@47108
  1004
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  1005
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  1006
huffman@47108
  1007
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  1008
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  1009
    after classes one and semigroup_add have been instantiated.
huffman@47108
  1010
huffman@47108
  1011
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  1012
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  1013
huffman@47108
  1014
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  1015
    automatically support numerals now, so more simp rules and
huffman@47108
  1016
    simprocs may now apply within the proof.
huffman@47108
  1017
huffman@47108
  1018
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
  1019
    Redefine using other integer operations.
huffman@47108
  1020
wenzelm@47855
  1021
* Transfer: New package intended to generalize the existing
wenzelm@47855
  1022
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  1023
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  1024
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  1025
corresponding parts of the Quotient package.)
wenzelm@47809
  1026
wenzelm@47809
  1027
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  1028
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  1029
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  1030
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  1031
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  1032
wenzelm@47809
  1033
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  1034
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  1035
wenzelm@47809
  1036
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  1037
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  1038
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  1039
    Goals are generalized over all free variables by default; this is
huffman@47851
  1040
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  1041
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  1042
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  1043
    is logically stronger (rather than equivalent).
wenzelm@47809
  1044
wenzelm@47809
  1045
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  1046
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  1047
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  1048
    non-polymorphic constants on the fly.
wenzelm@47809
  1049
wenzelm@47809
  1050
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  1051
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  1052
    constants that already have transfer rules. It should be applied
wenzelm@47809
  1053
    after unfolding the constant definitions.
wenzelm@47809

wenzelm@47809
  1056
    from type nat to type int.
wenzelm@47809
  1057
huffman@47851
  1058
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  1059
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  1060
wenzelm@47809
  1061
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  1062
    terms of a corresponding operation on a representation
wenzelm@47809
  1063
    type.  Example syntax:
wenzelm@47809
  1064
wenzelm@47809
  1065
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  1066
      is List.insert
wenzelm@47809
  1067
wenzelm@47809
  1068
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  1069
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  1070
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  1071
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  1072
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  1073
    by the package.
wenzelm@47809
  1074
wenzelm@47809
  1075
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  1076
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  1077
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  1078
    code generation for each constant.
wenzelm@47809
  1079
wenzelm@47809
  1080
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  1081
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  1082
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  1083
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  1084
    lift_definition command to work with the type.
wenzelm@47809
  1085
wenzelm@47809
  1086
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  1087
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  1088
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  1089
wenzelm@47809
  1090
* Quotient package:
wenzelm@47809
  1091
wenzelm@47809
  1092
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  1093
    rep and abs functions, similar to typedef.
wenzelm@47809
  1094
wenzelm@47809
  1095
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  1096
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  1097
wenzelm@47809
  1098
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  1099
    respectfulness property at the point where the constant is
wenzelm@47809
  1100
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  1101
wenzelm@47809
  1102
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  1103
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  1104
wenzelm@47809
  1105
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  1106
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  1107
wenzelm@47809
  1108
* Quickcheck:
wenzelm@47809
  1109
wenzelm@47809
  1110
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  1111
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  1112
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  1113
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  1114
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  1115
wenzelm@47809
  1116
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  1117
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  1118
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  1119
wenzelm@47809
  1120
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  1121
    continues searching for genuine ones.
wenzelm@47809
  1122
wenzelm@47809
  1123
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  1124
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  1125
    show genuine counterexamples.
wenzelm@47809
  1126
wenzelm@47809
  1127
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  1128
    value generators for a given type and operations.
wenzelm@47809
  1129
wenzelm@47809
  1130
    It generates values by using the operations as if they were
wenzelm@47809
  1131
    constructors of that type.
wenzelm@47809
  1132
wenzelm@47809
  1133
  - Support for multisets.
wenzelm@47809
  1134
wenzelm@47809
  1135
  - Added "use_subtype" options.
wenzelm@47809
  1136
wenzelm@47809
  1137
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  1138
    conjectures in a locale context.
wenzelm@47809
  1139
wenzelm@47855
  1140
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  1141
and affecting 'rat' and 'real'.
wenzelm@47809
  1142
wenzelm@47809
  1143
* Sledgehammer:
wenzelm@47809
  1144
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  1145
    paper "More SPASS with Isabelle".
wenzelm@47809
  1146
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  1147
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  1148
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  1149
  - Sped up the minimizer.
wenzelm@47809
  1150
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  1151
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  1152
  - Renamed "sound" option to "strict".
wenzelm@47809
  1153
wenzelm@47855
  1154
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  1155
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  1156
wenzelm@47855
  1157
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  1158
wenzelm@47855
  1159
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  1160
wenzelm@47856
  1161
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  1162
case distinctions at the same time.  E.g.
wenzelm@47856
  1163
wenzelm@47856
  1164
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  1165
wenzelm@47856
  1166
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  1167
a list and a nat.
wenzelm@47856
  1168
wenzelm@47809
  1169
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  1170
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  1171
wenzelm@47702
  1172
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  1173
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  1174
default.
wenzelm@47702
  1175
wenzelm@47856
  1176
* Record: code generation can be switched off manually with
wenzelm@47856
  1177
wenzelm@47856
  1178
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
  1179
wenzelm@47856
  1180
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
  1181
wenzelm@47855
  1182
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
  1183
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
  1184
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
  1185
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
  1186
one_case.
wenzelm@47855
  1187
wenzelm@47855
  1188
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
  1189
the result of the fact expression.
wenzelm@47855
  1190
haftmann@46752
  1191
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
  1192
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
  1193

wenzelm@47464
  1204
See theory "Relation" for examples for making use of pred/set

* Session HOL-Word: New proof method "word_bitwise" for splitting
wenzelm@47809
  1645
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  1646
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  1647
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  1648
constants.  Requires fixed-length word types, not 'a word.  Solves
wenzelm@47854
  1649
many standard word identities outright and converts more into first
wenzelm@47809
  1650
order problems amenable to blast or similar.  See also examples in
wenzelm@47809

HOL/Word/Examples/WordExamples.thy.

* Session HOL-Probability: Introduced the type "'a measure" to
wenzelm@47807
  1654
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807
  1655
measure_space.  The locales based on subset_class now have two
wenzelm@47856
  1656
locale-parameters the space \<Omega> and the set of measurable sets M.
wenzelm@47856
  1657
The product of probability spaces uses now the same constant as the
wenzelm@47856
  1658
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  1659
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  1660
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  1661
Measure space constructions for distributions and densities now got
wenzelm@47807
  1662
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  1663
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  1664
and point_measure is introduced.  INCOMPATIBILITY.

* Antiquotation @{keyword "name"} produces a parser for outer syntax
wenzelm@46948
  1848
from a minor keyword introduced via theory header declaration.
wenzelm@46948
  1849
wenzelm@46961
  1850
* Antiquotation @{command_spec "name"} produces the
wenzelm@46961
  1851
Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
  1852
header declaration; it can be passed to Outer_Syntax.command etc.
wenzelm@46961
  1853
wenzelm@46916
  1854
* Local_Theory.define no longer hard-wires default theorem name
wenzelm@46992
  1855
"foo_def", but retains the binding as given.  If that is Binding.empty
wenzelm@46992
  1856
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
  1857
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
  1858
non-empty name (used for the foundation in the background theory),
wenzelm@46992
  1859
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
  1860
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
  1861
naming policy for primitive definitions more explicitly.
wenzelm@46916
  1862
wenzelm@46497
  1863
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in
wenzelm@46497
  1864
conformance with similar operations in structure Term and Logic.
wenzelm@46497
  1865
wenzelm@45592
  1866
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
  1867
representation into the ML text, which is particularly useful with
wenzelm@45592
  1868
declarations like Local_Theory.note.
wenzelm@45592
  1869
wenzelm@45128
  1870
* Structure Proof_Context follows standard naming scheme.  Old

wenzelm@45128
  1872
wenzelm@45293
  1873
* Refined Local_Theory.declaration {syntax, pervasive}, with subtle
wenzelm@45298

* USER_HOME settings variable points to cross-platform user home
wenzelm@47661
  1896
directory, which coincides with HOME on POSIX systems only.  Likewise,
wenzelm@47661
  1897
the Isabelle path specification "~" now expands to $USER_HOME, instead
wenzelm@47661
  1898
of former $HOME.  A different default for USER_HOME may be set
wenzelm@47661
  1899
explicitly in shell environment, before Isabelle settings are
wenzelm@47661
  1900
evaluated.  Minor INCOMPATIBILITY: need to adapt Isabelle path where
wenzelm@47661
  1901
the generic user home was intended.
wenzelm@47661
  1902
wenzelm@47807
  1903
* ISABELLE_HOME_WINDOWS refers to ISABELLE_HOME in windows file name
wenzelm@47807
  1904
notation, which is useful for the jEdit file browser, for example.
wenzelm@47807
  1905

*** General ***
wenzelm@41703
  1915
wenzelm@44760
  1916
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
  1917
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760
  1918
wenzelm@44777
  1919
  - Management of multiple theory files directly from the editor
wenzelm@44760
  1920
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
  1921
    files for checking).
wenzelm@44760
  1922
wenzelm@44777
  1923
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
  1924
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
  1925
    positions.
wenzelm@44760
  1926
wenzelm@44777
  1927
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
  1928
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
  1929
    theory output and other non-Isabelle text boxes).
wenzelm@44777
  1930
wenzelm@44777
  1931
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
  1932
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
  1933
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
  1934
wenzelm@44777
  1935
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
  1936
    cores.
wenzelm@44760
  1937
wenzelm@44777
  1938
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
  1939
    versions (garbage collection).

  1942
including some remaining limitations.

* Theory loader: source files are exclusively located via the master
wenzelm@44800
  1945
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
  1946
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
  1947
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
  1948
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
  1949
INCOMPATIBILITY.
wenzelm@44800
  1950
wenzelm@41955
  1951
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
  1952
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
  1953
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
  1954
wenzelm@41703
  1955
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
  1956
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
  1957
usedir option -Q.
wenzelm@41703
  1958
wenzelm@42669
  1959
* Name space: former unsynchronized references are now proper
wenzelm@42669
  1960
configuration options, with more conventional names:
wenzelm@42669
  1961
wenzelm@42669
  1962
  long_names   ~> names_long
wenzelm@42669
  1963
  short_names  ~> names_short

  1964
  unique_names ~> names_unique
wenzelm@42669
  1965
wenzelm@42669
  1966
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
  1967
wenzelm@42669
  1968
  declare [[names_unique = false]]
wenzelm@42358
  1969
wenzelm@42502
  1970
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  1971
that the result needs to be unique, which means fact specifications
wenzelm@42502
  1972
may have to be refined after enriching a proof context.
wenzelm@42502
  1973
wenzelm@44800
  1974
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  1975
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  1976
wenzelm@44968
  1977
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  1978
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  1979
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
  1980
  - Updated material from classic "ref" manual, notably about

* Theory Complex_Main: The definition of infinite series was
wenzelm@44967
  2169
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
  2170
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
  2171
huffman@44908
  2172
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
  2173
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
  2174
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
  2175
wenzelm@44968
  2176
* Code generation:
wenzelm@44968
  2177
wenzelm@44968
  2178
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
  2179
    characters in the target language.
wenzelm@44968
  2180
wenzelm@44968
  2181
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
  2182
    instead.
wenzelm@44968
  2183
wenzelm@44968
  2184
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
  2185
wenzelm@44968
  2186
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
  2187
    reactivated by the following theory command:
wenzelm@44968
  2188
wenzelm@44968
  2189
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
  2190
wenzelm@44968
  2191
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
  2192
wenzelm@45088
  2193
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
  2194
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
  2195
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
  2196
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
  2197
syntax.
wenzelm@45088
  2198
wenzelm@44968
  2199
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
  2200
still available as a legacy feature for some time.
wenzelm@44968
  2201
wenzelm@44968
  2202
* Nitpick:
wenzelm@44968
  2203
  - Added "need" and "total_consts" options.
wenzelm@44968
  2204
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
  2205
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
  2206
    INCOMPATIBILITY.
wenzelm@44968
  2207
wenzelm@44968
  2208
* Sledgehammer:
wenzelm@44968
  2209
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
  2210
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
  2211
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
  2212
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
  2213
    this can be done within reasonable time.
wenzelm@44968
  2214
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
  2215
    INCOMPATIBILITY.
wenzelm@44968
  2216
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
  2217
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
  2218
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
  2219
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
  2220
wenzelm@44968
  2221
* Metis:
wenzelm@44968
  2222
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
  2223
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
  2224
    INCOMPATIBILITY.
wenzelm@44968
  2225
wenzelm@44968
  2226
* Command 'try':
wenzelm@44968
  2227
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
  2228
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
  2229
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
  2230
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
  2231
wenzelm@44968
  2232
* Quickcheck:
wenzelm@44968
  2233
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
  2234
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  2235
  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
  2236
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  2237
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  2238
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968
  2239
    with its installation location defined in the Isabelle settings
wenzelm@44968
  2240
    environment as ISABELLE_GHC.
wenzelm@44968
  2241
  - Removed quickcheck tester "SML" based on the SML code generator
wenzelm@44968
  2242
    (formly in HOL/Library).
wenzelm@44968
  2243
wenzelm@44968
  2244
* Function package: discontinued option "tailrec".  INCOMPATIBILITY,
wenzelm@44968
  2245
use 'partial_function' instead.
wenzelm@44968
  2246
wenzelm@44968
  2247
* Theory Library/Extended_Reals replaces now the positive extended
wenzelm@44968
  2248
reals found in probability theory. This file is extended by
wenzelm@44968
  2249
Multivariate_Analysis/Extended_Real_Limits.
wenzelm@44968
  2250
wenzelm@44974
  2251
* Theory Library/Old_Recdef: old 'recdef' package has been moved here,
wenzelm@44974
  2252
from where it must be imported explicitly if it is really required.
wenzelm@44974
  2253
INCOMPATIBILITY.
wenzelm@44968
  2254
wenzelm@44968
  2255
* Theory Library/Wfrec: well-founded recursion combinator "wfrec" has
wenzelm@44968
  2256
been moved here.  INCOMPATIBILITY.
wenzelm@44968
  2257
wenzelm@44968
  2258
* Theory Library/Saturated provides type of numbers with saturated
wenzelm@44968
  2259
arithmetic.
wenzelm@44968
  2260
wenzelm@44968
  2261
* Theory Library/Product_Lattice defines a pointwise ordering for the
wenzelm@44968
  2262
product type 'a * 'b, and provides instance proofs for various order
wenzelm@44968
  2263
and lattice type classes.
wenzelm@44968
  2264
wenzelm@44968
  2265
* Theory Library/Countable now provides the "countable_datatype" proof
wenzelm@44968
  2266
method for proving "countable" class instances for datatypes.
wenzelm@44968
  2267
wenzelm@44968
  2268
* Theory Library/Cset_Monad allows do notation for computable sets
wenzelm@44968
  2269
(cset) via the generic monad ad-hoc overloading facility.
wenzelm@44968
  2270
wenzelm@44968
  2271
* Library: Theories of common data structures are split into theories
wenzelm@44968
  2272
for implementation, an invariant-ensuring type, and connection to an
wenzelm@44968
  2273
abstract type. INCOMPATIBILITY.
wenzelm@44968
  2274
wenzelm@44968
  2275
  - RBT is split into RBT and RBT_Mapping.
wenzelm@44968
  2276
  - AssocList is split and renamed into AList and AList_Mapping.
wenzelm@44968
  2277
  - DList is split into DList_Impl, DList, and DList_Cset.
wenzelm@44968
  2278
  - Cset is split into Cset and List_Cset.
wenzelm@44968
  2279
wenzelm@44968
  2280
* Theory Library/Nat_Infinity has been renamed to
wenzelm@44968
  2281
Library/Extended_Nat, with name changes of the following types and
wenzelm@44968
  2282
constants:
wenzelm@44968
  2283
wenzelm@44968
  2284
  type inat   ~> type enat
wenzelm@44968
  2285
  Fin         ~> enat
wenzelm@44968
  2286
  Infty       ~> infinity (overloaded)
wenzelm@44968
  2287
  iSuc        ~> eSuc
wenzelm@44968
  2288
  the_Fin     ~> the_enat
wenzelm@44968
  2289
wenzelm@44968
  2290
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has
wenzelm@44968
  2291
been renamed accordingly. INCOMPATIBILITY.
wenzelm@44968
  2292
wenzelm@44968
  2293
* Session Multivariate_Analysis: The euclidean_space type class now
wenzelm@44968
  2294
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  2295
orthonormal basis for the type. Users now have the option of
wenzelm@44968
  2296
quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968
  2297
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".
wenzelm@44968
  2298
wenzelm@44968
  2299
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed
wenzelm@44968
  2300
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  2301
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  2302
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  2303
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  2304
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  2305
been renamed as follows (INCOMPATIBILITY):
wenzelm@44968
  2306
wenzelm@44968
  2307
  Cart_eq          ~> vec_eq_iff
wenzelm@44968
  2308
  dist_nth_le_cart ~> dist_vec_nth_le
wenzelm@44968
  2309
  tendsto_vector   ~> vec_tendstoI

  2310
  Cauchy_vector    ~> vec_CauchyI
wenzelm@44968
  2311
wenzelm@44968
  2312
* Session Multivariate_Analysis: Several duplicate theorems have been
wenzelm@44968
  2313
removed, and other theorems have been renamed or replaced with more
wenzelm@44968
  2314
general versions. INCOMPATIBILITY.

wenzelm@43731
  2433
* The inner syntax of sort/type/term/prop supports inlined YXML
wenzelm@43731
  2434
representations within quoted string tokens.  By encoding logical
wenzelm@43731
  2435
entities via Term_XML (in ML or Scala) concrete syntax can be
wenzelm@43731
  2436
bypassed, which is particularly useful for producing bits of text

  2437
under external program control.
wenzelm@43731

  2455
* Inner syntax: identifiers in parse trees of generic categories
wenzelm@42056
  2456
"logic", "aprop", "idt" etc. carry position information (disguised as
wenzelm@42056
  2457
type constraints).  Occasional INCOMPATIBILITY with non-compliant
wenzelm@42057
  2458
translations that choke on unexpected type constraints.  Positions can
wenzelm@42057
  2459
be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  2460
Syntax.strip_positions_ast, or via the syntax constant
wenzelm@42057
  2461
"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  2462
be disabled via the configuration option Syntax.positions, which is
wenzelm@42057
  2463
called "syntax_positions" in Isar attribute syntax.

  2464
wenzelm@42290
  2465
* Discontinued special status of various ML structures that contribute
wenzelm@42290

wenzelm@42370
  2476
wenzelm@42403
  2477
* Slightly more special eq_list/eq_set, with shortcut involving

  2478
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  2479
wenzelm@42793
  2480
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  2481
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  2482
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  2483
snapshot of the classical context, which can be recovered via
wenzelm@42793
  2484
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.
wenzelm@42793
  2485
INCOMPATIBILITY, classical tactics and derived proof methods require

* Scala layer provides JVM method invocation service for static
wenzelm@44800
  2510
methods of type (String)String, see Invoke_Scala.method in ML.  For
wenzelm@44800
  2511
example:
wenzelm@43752
  2512
wenzelm@43752
  2513
  Invoke_Scala.method "java.lang.System.getProperty" "java.home"
wenzelm@43752

wenzelm@44967
  2515
Together with YXML.string_of_body/parse_body and XML.Encode/Decode
wenzelm@44967
  2516
this allows to pass structured values between ML and Scala.

*** General ***
wenzelm@37536
  2529
wenzelm@41573
  2530
* Experimental Prover IDE based on Isabelle/Scala and jEdit (see
wenzelm@41612
  2531
src/Tools/jEdit).  This also serves as IDE for Isabelle/ML, with
wenzelm@41612
  2532
useful tooltips and hyperlinks produced from its static analysis.  The
wenzelm@41612
  2533
bundled component provides an executable Isabelle tool that can be run
wenzelm@41612
  2534
like this:
wenzelm@41612
  2535
wenzelm@41612
  2536
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  2537
wenzelm@40948
  2538
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  2539
wenzelm@41594
  2540
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  2541
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  2542
while the default heap location within that directory lacks that extra
wenzelm@41594
  2543
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  2544
other, avoiding problems with old settings in new versions.
wenzelm@41594
  2545
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  2546
wenzelm@40947
  2547
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  2548
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  2549
the following package declarations:
wenzelm@40947
  2550
wenzelm@40947
  2551
  \usepackage[utf8]{inputenc}
wenzelm@40947
  2552
  \usepackage{textcomp}
wenzelm@40947
  2553
krauss@41440
  2554
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  2555
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  2556
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  2557
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  2558
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  2559
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  2560
merely give a byte-oriented representation.
wenzelm@37536
  2561
wenzelm@41594
  2562
* Theory loader: source files are primarily located via the master
wenzelm@41594
  2563
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  2564
The global load path is still partially available as legacy feature.
wenzelm@41594
  2565
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  2566
explicit paths, relatively to the theory.
wenzelm@38135
  2567
wenzelm@37939
  2568
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  2569
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  2570
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  2571
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  2572
wenzelm@38980
  2573
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  2574
handled within the context via configuration options, instead of
wenzelm@40879
  2575
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879
  2576
entities and Isar declaration attributes to access these.

  2604
changed globally at the ROOT session setup, but *not* within a theory.
wenzelm@40879

The option "show_abbrevs" supersedes the former print mode

* Coercive subtyping: functions can be declared as coercions and type
wenzelm@41594
  2676
inference will add them as necessary upon input of a term.  Theory
wenzelm@41594
  2677
Complex_Main declares real :: nat => real and real :: int => real as
wenzelm@41594
  2678
coercions. A coercion function f is declared like this:
wenzelm@40939
  2679
wenzelm@40939
  2680
  declare [[coercion f]]
nipkow@40866
  2681
wenzelm@41571
  2682
To lift coercions through type constructors (e.g. from nat => real to
nipkow@40866
  2683
nat list => real list), map functions can be declared, e.g.
nipkow@40866
  2684
wenzelm@40939
  2685
  declare [[coercion_map map]]
wenzelm@40939
  2686
wenzelm@40939
  2687
Currently coercion inference is activated only in theories including
wenzelm@40939
  2688
real numbers, i.e. descendants of Complex_Main.  This is controlled by
wenzelm@41020
  2689
the configuration option "coercion_enabled", e.g. it can be enabled in
wenzelm@40939
  2690
other theories like this:
wenzelm@40939
  2691
wenzelm@40939
  2692
  declare [[coercion_enabled]]
