*** General ***
wenzelm@54702
     8
wenzelm@54702
     9
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@54702
    10
which results in an active hyperlink within the text.
wenzelm@54702
    11
wenzelm@54705
    12
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@54705
    13
not check existence within the file-system.
wenzelm@54705
    14
wenzelm@54732
    15
* Discontinued legacy_isub_isup, which was a temporary Isabelle/ML
wenzelm@54732
    16
workaround in Isabelle2013-1.  The prover process no longer accepts
wenzelm@54732
    17
old identifier syntax with \<^isub> or \<^isup>.
wenzelm@54732
    18
wenzelm@55029
    19
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@55029
    20
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@55029
    21
string token.  Minor INCOMPATIBILITY.
wenzelm@55029
    22
wenzelm@55122
    23
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@55668
    24
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@55668
    25
supports input methods via ` (backquote), or << and >> (double angle
wenzelm@55668
    26
brackets).
wenzelm@55122
    27
wenzelm@54702

wenzelm@54533
    29
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
    30
wenzelm@54533
    31
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@54533
    32
Open text buffers take precedence over copies within the file-system.
wenzelm@54533
    33
wenzelm@55536
    34
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@55536
    35
auxiliary ML files.
wenzelm@55536
    36
wenzelm@55654
    37
* Improved completion based on context information about embedded
wenzelm@55716
    38
languages: keywords are only completed for outer syntax, symbols or
wenzelm@55716
    39
antiquotations for languages that support them.  E.g. no symbol
wenzelm@55716
    40
completion for ML source, but within ML strings, comments,
wenzelm@55716
    41
antiquotations.
wenzelm@55654
    42
wenzelm@54688
    43
* Document panel: simplied interaction where every single mouse click
wenzelm@54688
    44
(re)opens document via desktop environment or as jEdit buffer.
wenzelm@54688
    45
wenzelm@54881
    46
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
    47
General") allows to specify additional print modes for the prover
wenzelm@54881
    48
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
    49
"isabelle jedit -m MODE".
wenzelm@54881
    50
lars@55316
    51
* New panel: Simplifier trace.  Provides an interactive view of the
lars@55316
    52
simplification process, enabled by the newly-introduced
lars@55316
    53
"simplifier_trace" declaration.
lars@55316

wenzelm@55001
    56
*** Pure ***
wenzelm@55001
    57
wenzelm@55385
    58
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@55385
    59
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@55385
    60
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@55385
    61
'instance' with proof.  The required OFCLASS(...) theorem might be
wenzelm@55385
    62
postulated via 'axiomatization' beforehand, or the proof finished
wenzelm@55385
    63
trivially if the underlying class definition is made vacuous (without
wenzelm@55385
    64
any assumptions).  See also Isabelle/ML operations
wenzelm@55385
    65
Axclass.axiomatize_class, Axclass.axiomatize_classrel,
wenzelm@55385
    66
Axclass.axiomatize_arity.
wenzelm@55385
    67
wenzelm@55143
    68
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
    69
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
    70
instantiated theorem.
wenzelm@55143
    71
wenzelm@55152
    72
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
    73
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
    74
where instantiations with schematic variables are intended (for
wenzelm@55152
    75
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
    76
following temporary definition may help to port old applications:
wenzelm@55152
    77
wenzelm@55152
    78
  attribute_setup standard =
wenzelm@55152
    79
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
    80
wenzelm@55001
    81
* More thorough check of proof context for goal statements and
wenzelm@55006
    82
attributed fact expressions (concerning background theory, declared
wenzelm@55006
    83
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
    84
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
    85
primitive Thm.assume_hyps.
wenzelm@55001
    86
wenzelm@55108
    87
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
    88
(only makes sense in practice, if outer syntax is delimited
wenzelm@55108
    89
differently).
wenzelm@55108

haftmann@54227
    92
*** HOL ***
haftmann@54227
    93
haftmann@55818
    94
* HOL-Word:
haftmann@55818
    95
  * Abandoned fact collection "word_arith_alts", which is a
haftmann@55818
    96
  duplicate of "word_arith_wis".
haftmann@55818
    97
  * Dropped first (duplicated) element in fact collections
haftmann@55818
    98
  "sint_word_ariths", "word_arith_alts", "uint_word_ariths",
haftmann@55818
    99
  "uint_word_arith_bintrs".
haftmann@55818
   100
haftmann@55757
   101
* Code generator: explicit proof contexts in many ML interfaces.
haftmann@55757
   102
INCOMPATIBILITY.
haftmann@55757
   103
haftmann@55686
   104
* Code generator: minimize exported identifiers by default.
haftmann@55757
   105
Minor INCOMPATIBILITY.
haftmann@55686
   106
haftmann@55677
   107
* Code generation for SML and OCaml: dropped arcane "no_signatures" option.
haftmann@55757
   108
Minor INCOMPATIBILITY.
haftmann@55677
   109
wenzelm@55139
   110
* Simproc "finite_Collect" is no longer enabled by default, due to
wenzelm@55139
   111
spurious crashes and other surprises.  Potential INCOMPATIBILITY.
wenzelm@55139
   112
blanchet@55098
   113
* Moved new (co)datatype package and its dependencies from "HOL-BNF" to "HOL".
blanchet@55098
   114
  The "bnf", "wrap_free_constructors", "datatype_new", "codatatype",
blanchet@55875
   115
  "primcorec", and "primcorecursive" commands are now part of "Main".

blanchet@55875
   162
    INCOMPATIBILITY.
blanchet@55875
   163
blanchet@55643
   164
* Old datatype package:

   173
  relators, and their selectors are now produced using the new BNF-based
blanchet@55585
   174
  datatype package.
blanchet@55519
   175
  Renamed constants:

   205
    Cardinals/Ordinal_Arithmetic.thy
blanchet@55098
   206
blanchet@55098

  * Big_Operators.thy ~> Groups_Big.thy and Lattices_Big.thy
blanchet@55098
   209
blanchet@55183
   210
* Sledgehammer:
blanchet@55289
   211
  - New option:
blanchet@55297
   212
      smt_proofs
blanchet@55183

blanchet@55183
   216
    INCOMPATIBILITY.
blanchet@55183
   217
blanchet@55315
   218
* Metis:
blanchet@55315
   219
  - Removed legacy proof method 'metisFT'. Use 'metis (full_types)' instead.
blanchet@55315
   220
    INCOMPATIBILITY.
blanchet@55315
   221
blanchet@55183
   222
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
blanchet@55183
   223
blanchet@55519
   224
* Command renaming: enriched_type ~> functor. INCOMPATIBILITY.
blanchet@55519
   225
wenzelm@55015
   226

   228
wenzelm@55007
   229
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@55007
   230
(without requiring restart), instead of former settings variable
wenzelm@55007
   231
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu
wenzelm@55007
   232
Plugin Options / Isabelle / General.
wenzelm@55007
   233
wenzelm@54893
   234
* "declare [[code abort: ...]]" replaces "code_abort ...".
wenzelm@54893
   235
INCOMPATIBILITY.
wenzelm@54893
   236
wenzelm@54893
   237
* "declare [[code drop: ...]]" drops all code equations associated

   238
with the given constants.
haftmann@54890
   239
haftmann@54864

Consider simplification with algebra_simps or field_simps.
haftmann@54230
   354
haftmann@54230
   355

   356
Try with "using <rule for addition> of [... "- _" ...]" by simp".
haftmann@54230
   357
haftmann@54230
   358
c) Simplification with "diff_def": just drop "diff_def".

Consider simplification with algebra_simps or field_simps;
haftmann@54230
   360

wenzelm@55143
   408
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@55143
   409
variables that are meant to become schematic need to be given as
wenzelm@55143
   410
fixed, and are generalized by the explicit context of local variables.
wenzelm@55143
   411
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@55143
   412
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@55143
   413
of schematic variables.
wenzelm@55143
   414
wenzelm@54449
   415

   420
* Proper context for basic Simplifier operations: rewrite_rule,

rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@54742
   422
pass runtime Proof.context (and ensure that the simplified entity

   423
actually belongs to it).
wenzelm@54742
   424
wenzelm@55547
   425
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@55547
   426
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@55547
   427
current background theory.  Thus equivalent data produced in different
wenzelm@55547
   428
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@55547
   429
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@55547
   430
appropriate than Thm.eq_thm.

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

wenzelm@53971
   525
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
   526
Documentation panel.
wenzelm@53852
   527
wenzelm@53971
   528
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
   529
documentation.
wenzelm@52646
   530
wenzelm@52949
   531
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
   532
(GUI front-end to 'find_theorems' command).
wenzelm@52949
   533
wenzelm@53050
   534
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
   535
sledgehammer runs over existing document sources, independently of
wenzelm@53050
   536
normal editing and checking process.
wenzelm@53050
   537
wenzelm@51533
   538
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
   539
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
   540
same timing information is shown in the extended tooltip of the
wenzelm@54332
   541
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
   542
COMMAND modifier is pressed.
wenzelm@51533
   543
wenzelm@53971
   544
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
   545
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
   546
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
   547
be marked explicitly as required and checked in full, using check box
wenzelm@53971
   548
or shortcut "C+e SPACE".
wenzelm@53971
   549
wenzelm@54305
   550
* Improved completion mechanism, which is now managed by the
wenzelm@54305
   551
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
   552
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
   553
wenzelm@54319
   554
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
   555
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
   556
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
   557
to resolve conflict.
wenzelm@54319
   558
wenzelm@54305
   559
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
   560
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
   561
wenzelm@53971
   562
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
   563
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
   564
such command executions while editing.
wenzelm@53271
   565
wenzelm@53971
   566
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
   567
document content.
wenzelm@53971
   568
wenzelm@53971
   569
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
   570
toplevel theorem statements.
wenzelm@53971
   571
wenzelm@53971
   572
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
   573
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
   574
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
   575
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
   576
wenzelm@53971
   577
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
   578
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
   579
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
   580
wenzelm@53971
   581
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
   582
/ Global Options / Appearance".
wenzelm@53971
   583
wenzelm@53971
   584
* Improved support of native Mac OS X functionality via "MacOSX"
wenzelm@53971
   585
plugin, which is now enabled by default.

*** Pure ***
wenzelm@51313
   589
ballarin@54049
   590
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
   591
In particular, 'interpretation' allows for non-persistent
ballarin@54049
   592
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
   593
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
   594
details.
haftmann@51747
   595
ballarin@51565
   596
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
   597
wenzelm@51313
   598
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
   599
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
   600
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
   601
wenzelm@51316
   602
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
   603
INCOMPATIBILITY.
wenzelm@51316
   604
wenzelm@53971
   605
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
   606
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
   607
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
   608
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
   609
wenzelm@53971
   610
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
   611
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
   612
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
   613
wenzelm@53971
   614
* Former global reference trace_unify_fail is now available as
wenzelm@53971
   615
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
   616
wenzelm@52463
   617
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
   618
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
   619
situations.

hoelzl@51002
   622
*** HOL ***
hoelzl@51002
   623
wenzelm@54032
   624
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
   625
sets, in accordance with corresponding lattice operations.
wenzelm@54032
   626
INCOMPATIBILITY.
wenzelm@54032
   627
wenzelm@54032
   628
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
   629
wenzelm@54032
   630
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
   631
rather than during parsing. The data for case combinators is separated
wenzelm@54032
   632
from the datatype package. The declaration attribute
wenzelm@54032
   633
"case_translation" can be used to register new case combinators:
wenzelm@54032
   634
wenzelm@54032
   635
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
   636
haftmann@52435
   637
* Code generator:
wenzelm@53160
   638
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
   639
    'code_instance'.
wenzelm@53160
   640
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
   641
    generated code, subsuming 'code_modulename'.
wenzelm@53983
   642
wenzelm@53983
   643
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
   644
examples.
haftmann@52435
   645
wenzelm@54032
   646
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
   647
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
   648
to distinguish both when desired.
wenzelm@54032
   649
wenzelm@54032
   650
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
   651
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
   652
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
   653
generation for details.  INCOMPATIBILITY.
wenzelm@54032
   654
wenzelm@54032
   655
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
   656
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
   657
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
   658
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
   659
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
   660
ML).  INCOMPATIBILITY.
wenzelm@54032
   661
wenzelm@54032
   662
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
   663
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
   664
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
   665
in the case that the unusable rule was used nevertheless.
wenzelm@54032
   666
wenzelm@54032
   667
* Function package: For each function f, new rules f.elims are
wenzelm@54032
   668
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
   669
wenzelm@54032
   670
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
   671
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
   672
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
   673
kuncar@54021
   674
* Lifting:
kuncar@54021
   675
  - parametrized correspondence relations are now supported:
wenzelm@54378
   676
    + parametricity theorems for the raw term can be specified in
kuncar@54021
   677
      the command lift_definition, which allow us to generate stronger
kuncar@54021
   678
      transfer rules
kuncar@54021
   679
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
   680
      correspondence relation can be generated
kuncar@54021
   681
    + various new properties of the relator must be specified to support
kuncar@54021
   682
      parametricity
kuncar@54021
   683
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
   684
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
   685
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
   686
    copies
kuncar@54021
   687
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
   688
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
   689
    anonymous context)
wenzelm@54378
   690
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
   691
    Main. Potential INCOMPATIBILITY
kuncar@54021
   692
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
   693
    lifting_forget, lifting_update
wenzelm@54378
   694
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
   695
    INCOMPATIBILITY
kuncar@54021
   696
kuncar@54021
   697
* Transfer:
wenzelm@54378
   698
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
   699
    by the actual invariant in a transferred goal
kuncar@54021
   700
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
   701
  - Experimental support for transferring from the raw level to the
kuncar@54021
   702
    abstract level: Transfer.transferred attribute
kuncar@54021
   703
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
   704
haftmann@52286
   705
* Reification and reflection:
wenzelm@53160
   706
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
   707
    "Reification".
wenzelm@53160
   708
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
   709
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
   710
INCOMPATIBILITY.
haftmann@52286
   711
haftmann@51489
   712
* Revised devices for recursive definitions over finite sets:
haftmann@51489
   713
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
   714
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
   715
    This is now identity on infinite sets.
wenzelm@52745
   716
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
   717
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
   718
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
   719
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
   720
    See theory Big_Operators for canonical examples.
haftmann@51489
   721
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
   722
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
   723
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
   724
    those foundational constants as substitutes, but it is
wenzelm@53983
   725
    preferable to interpret the above locales accordingly.
haftmann@51489
   726
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
   727
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
   728
  - Fact renames:
haftmann@51489
   729
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
   730
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
   731
INCOMPATIBILITY.
haftmann@51489
   732
haftmann@51487
   733
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
   734
wenzelm@53526
   735
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
   736
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
   737
class predicate assumption or sort constraint when possible.
Andreas@53362
   738
INCOMPATIBILITY.
Andreas@53362
   739
wenzelm@53160
   740
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
   741
complete lattice but does not assume the existence of the top and
wenzelm@53160
   742
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
   743
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
   744
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
   745
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
   746
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
   747
lemmas.
wenzelm@53160
   748
wenzelm@53160
   749
* Introduce type class linear_continuum as combination of
wenzelm@53160
   750
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
   751
more than one element.  INCOMPATIBILITY.
wenzelm@53160
   752
wenzelm@53983
   753
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
   754
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
   755
Rename bot -> order_bot, top -> order_top
lammich@53683
   756
wenzelm@53160
   757
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
   758
top and bottom elements.
hoelzl@51732
   759
hoelzl@51732
   760
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
   761
hoelzl@51732
   762
* Complex_Main: Unify and move various concepts from
wenzelm@53160
   763
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
   764
wenzelm@53983
   765
 - Introduce type class (lin)order_topology and
wenzelm@53983
   766
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
   767
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
   768
hoelzl@51732
   769
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
   770
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
   771
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
   772
wenzelm@53983
   773
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
   774
   arbitrary filter.
wenzelm@53983
   775
wenzelm@53983
   776
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
   777
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
   778
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
   779
   continuous function is continuous, when the function is continuous
wenzelm@53983
   780
   on a compact set.
hoelzl@51732
   781
hoelzl@51732
   782
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
   783
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
   784
   linear_continuum_topology).
hoelzl@51732
   785
hoelzl@51732
   786
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
   787
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
   788
   on all sequences converging to x.
wenzelm@53983
   789
wenzelm@53983
   790
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
   791
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
   792
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
   793
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983

 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
   797
hoelzl@51732
   798
     F within X = inf F (principal X)
hoelzl@51732
   799
hoelzl@51732
   800
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
   801
   abbreviation for "at x within UNIV"
hoelzl@51732
   802
wenzelm@53983
   803
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
   804
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
   805
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
   806
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
   807
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
   808
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
   809
hoelzl@51732
   810
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
   811
hoelzl@51732
   812
   + Moved RealDef and RComplete into Real
hoelzl@51732
   813
hoelzl@51732
   814
   + Introduced Topological_Spaces and moved theorems about

     topological spaces, filters, limits and continuity to it
hoelzl@51732
   816
hoelzl@51732
   817
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
   818
wenzelm@53983
   819
   + Split Lim, SEQ, Series into Topological_Spaces,

   820
     Real_Vector_Spaces, and Limits
hoelzl@51732
   821
hoelzl@51732
   822
   + Moved Ln and Log to Transcendental
hoelzl@51732

hoelzl@51732
   824
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
   825
hoelzl@51732
   826
 - Remove various auxiliary lemmas.

wenzelm@54032
   844
wenzelm@54032

* Library/Polynomial.thy:
wenzelm@54032
   846
  - Use lifting for primitive definitions.
wenzelm@54032
   847
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032

  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
   850
  - Prefer pre-existing gcd operation for gcd.

* Consolidation of library theories on product orders:
wenzelm@54032

wenzelm@54032
   869
    Product_Lattice ~> Product_Order -- pointwise order on products

   878
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
   879
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983
   880
~~/src/HOL/Library/Polynomial instead.  The latter provides
wenzelm@53983
   881
integration with HOL's type classes for rings.  INCOMPATIBILITY.

* HOL-BNF:
wenzelm@54032
   884
  - Various improvements to BNF-based (co)datatype package, including
wenzelm@54032
   885
    new commands "primrec_new", "primcorec", and
wenzelm@54032
   886
    "datatype_new_compat", as well as documentation. See
wenzelm@54032
   887
    "datatypes.pdf" for details.
wenzelm@54032
   888
  - New "coinduction" method to avoid some boilerplate (compared to
wenzelm@54032
   889
    coinduct).
wenzelm@54032
   890
  - Renamed keywords:

*** ML ***
wenzelm@51551
   905
wenzelm@53971
   906
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
   907
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
   908
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its

   909
Examples.thy in particular.
wenzelm@53971
   910
wenzelm@53709
   911
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709
   912
tracing output in the command transaction context instead of physical
wenzelm@53709
   913

wenzelm@53971
   916
* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
   917
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
   918
the past).  Discontinued obsolete operations like Theory.copy,

Theory.checkpoint, and the auxiliary type theory_ref.  Minor
wenzelm@53971
   920
INCOMPATIBILITY.
wenzelm@53164
   921
wenzelm@51551

   924
    Skip_Proof.prove  ~>  Goal.prove_sorry

   927
Minor INCOMPATIBILITY.
wenzelm@51703
   928
wenzelm@51717
   929
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
   930
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
   931
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
   932
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
   933
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
   934
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
   935
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
   936
wenzelm@53971
   937
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
   938
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
   939
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
   940
clasets separately from the context.
wenzelm@53971
   941
wenzelm@51717
   942
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.
wenzelm@51717
   943
INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
   944
wenzelm@53971

always pdf.
wenzelm@52743
   963
wenzelm@52053
   964

wenzelm@52116
   969
wenzelm@52439
   970
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
   971
keyword tables): use Isabelle/Scala operations, which inspect outer
wenzelm@52439
   972
syntax without requiring to build sessions first.
wenzelm@52439
   973
wenzelm@53971
   974
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971
   975
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@53971
   976
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
   977
tendency towards erratic fluctuation of URLs) has been discontinued.

wenzelm@50126
   988
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
   989
no longer printed by default, since it is incompatible with
wenzelm@50126
   990
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
   991
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
   992
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
   993
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
   994
accessible theorems in the theory context are finished (as before).
wenzelm@50126
   995
wenzelm@49699
   996
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
   997
into the printed representation of formal entities --- notably type
wenzelm@49699
   998
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
   999
information via tooltips in the output window, for example.
wenzelm@49699
  1000
wenzelm@48890
  1001
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  1002
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  1003
wenzelm@49243
  1004
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  1005
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  1006
Tools that load their additional source files may imitate the
wenzelm@49243
  1007
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  1008
dependencies properly.
wenzelm@49243
  1009
wenzelm@47967
  1010
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  1011
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  1012
wenzelm@50110
  1013
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  1014
remaining material in old "ref" manual.
wenzelm@48120
  1015
wenzelm@51050
  1016
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  1017
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  1018
and "class ... context ...".
wenzelm@49841
  1019
wenzelm@50772
  1020
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  1021
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  1022
the target context.  This form of declaration is stable when exported
wenzelm@50772
  1023
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  1024
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  1025
in HOL/inductive and HOL/function.
wenzelm@50772
  1026
wenzelm@49869
  1027
* More informative error messages for Isar proof commands involving
wenzelm@49869
  1028
lazy enumerations (method applications etc.).
wenzelm@49869
  1029
wenzelm@50213
  1030
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  1031
to name patterns (with clickable results).

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  1035
wenzelm@49968
  1036
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  1037
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  1038
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  1039
surface, while the prover is still crunching on internal
wenzelm@49968
  1040
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  1041
required to complete full proof checking eventually.
wenzelm@49968
  1042
wenzelm@49968
  1043
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  1044
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  1045
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  1046
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  1047
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  1048
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  1049
wenzelm@50717
  1050
* Improved support for commands that produce graph output: the text
wenzelm@50717
  1051
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  1052
browser on demand.
wenzelm@50717
  1053
wenzelm@49968
  1054
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  1055
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  1056
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  1057
that frequently occur in user interaction.
wenzelm@49968
  1058
wenzelm@49968
  1059
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  1060
files.  More scalable management of formal document content.
wenzelm@49968
  1061
wenzelm@50505
  1062
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  1063
certain number of messages per command transaction, with some user
wenzelm@50505
  1064
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  1065
potentially infinite message streams.
wenzelm@49968
  1066
wenzelm@49968
  1067
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  1068
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  1069
options, including tuning parameters for editor reactivity and color

wenzelm@50184
  1073
symbols.
wenzelm@50184
  1074
wenzelm@51082
  1075
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  1076
continuous display of the chart slows down the system.
wenzelm@50701
  1077
wenzelm@50183
  1078
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  1079
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  1080
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.

wenzelm@50198
  1082
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  1083
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  1084
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  1085
need to be adapted to local keyboard layouts.
wenzelm@50183
  1086
wenzelm@50730
  1087
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  1088
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730

image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  1093
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  1094

* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  1097
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  1098
now bundled exclusively with Isabelle.

Haskell Prelude to a small set of fundamental operations.
haftmann@48431

* Command 'export_code': relative file names are interpreted
wenzelm@50646
  1107
relatively to master directory of current theory rather than the
wenzelm@50646
  1108
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371

* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  1111
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  1112
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  1113
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  1114
with some care where this is really required.
wenzelm@48205
  1115
wenzelm@48792
  1116
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  1117
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  1118
given sort.  Example (in HOL):
wenzelm@48792
  1119
wenzelm@48792
  1120
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
  1121
wenzelm@50716

* Sledgehammer:
wenzelm@50646
  1129
wenzelm@50646
  1130
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
  1131
    Sledgehammer manual for details.
wenzelm@50646
  1132
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
  1133
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
  1134
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
  1135

* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
  1142
switched on by default, and can be switched off by setting the
wenzelm@50646
  1143
configuration quickcheck_optimise_equality to false.

  - generation of an abstraction function equation in lift_definition
kuncar@50878

wenzelm@50646
  1155
wenzelm@50646

* Preprocessing of the code generator rewrites set comprehensions into
wenzelm@50646
  1157
pointfree expressions.
wenzelm@50646
  1158
wenzelm@50646
  1159
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
  1160
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
  1161
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
  1162
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
  1163
INCOMPATIBILITY.
haftmann@49948
  1164
wenzelm@49836
  1165
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  1166
set definition and alternative name have been discontinued.  The
wenzelm@49836
  1167
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
  1168
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
  1169
accordingly.
wenzelm@49836
  1170
wenzelm@50646
  1171
* Removed constant "chars"; prefer "Enum.enum" on type "char"

wenzelm@50646
  1173
wenzelm@50646

haftmann@49738
  1179
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
  1180
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
  1181
wenzelm@50646
  1182
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
  1183
wenzelm@50646
  1184
* Theory "Transitive_Closure": renamed lemmas

  1198
* Generalized the definition of limits:
wenzelm@50646
  1199
wenzelm@50646
  1200
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  1201
    expresses that when the input values x converge to F then the
wenzelm@50646
  1202
    output f x converges to G.
wenzelm@50646
  1203
wenzelm@50646
  1204
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  1205
    infinity (at_bot).
wenzelm@50646
  1206
wenzelm@50646
  1207
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  1208
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  1209
wenzelm@50646
  1210
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
  1211
    at_top".

  1216
lattice type classes.
wenzelm@50646
  1217
wenzelm@50646
  1218

  1225
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  1226
changes as follows.
wenzelm@50646
  1227
wenzelm@50646
  1228

Christian@49145
  1231
      strict_prefix ~> prefix
Christian@49145
  1232
wenzelm@50646
  1233
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  1234
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  1235
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  1236
    Renamed lemmas accordingly.
wenzelm@50646
  1237
wenzelm@50646
  1238
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  1239
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  1240
    "list_hembeq (op =)".
wenzelm@50646
  1241
wenzelm@50646
  1242
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  1243
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  1244
    interpretations). The type class instances are now in theory
wenzelm@50646
  1245
    Library/Prefix_Order.
wenzelm@50646
  1246
wenzelm@50646
  1247
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
  1248
    on "Sublist.sublisteq".  Renamed lemmas accordingly:

wenzelm@50646
  1345
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
  1346
wenzelm@50646
  1347
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
  1348
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
  1349
    (borel_measurable_induct).
wenzelm@50646
  1350
wenzelm@50646
  1351
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a

wenzelm@48206
  1376
wenzelm@50646

* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  1378
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  1379
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  1380
wenzelm@50646
  1381
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  1382
instead of slightly exotic babel/greek.
wenzelm@48206
  1383
wenzelm@48616
  1384
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  1385
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  1386
document/root.tex.
wenzelm@48616
  1387
wenzelm@48657

wenzelm@48992
  1393
wenzelm@50646
  1394
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  1395
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  1396
hardware and Poly/ML runtime system.
wenzelm@50646
  1397
wenzelm@49869
  1398
* Type Seq.results and related operations support embedded error
wenzelm@49869
  1399
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  1400
informative errors in the absence of any usable results.
wenzelm@49869
  1401
wenzelm@48992
  1402
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  1403
formal device to inline positions into message text, but not
wenzelm@48992
  1404
necessarily printing visible text.

*** System ***
wenzelm@48206
  1408
wenzelm@48585
  1409
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  1410
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  1411
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  1412
session root directories for use with "isabelle build", similar to
wenzelm@51056
  1413
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  1414
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  1415
mkdir / make are rendered obsolete.
wenzelm@48736
  1416
wenzelm@51056
  1417
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  1418
regular isabelle build tool.  For example:
wenzelm@51056
  1419
wenzelm@51056
  1420
  isabelle build -s -b HOL
wenzelm@51056
  1421
wenzelm@48736
  1422
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  1423
wenzelm@48722
  1424
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  1425
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  1426
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  1427
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  1428
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  1429
wenzelm@48693
  1430
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  1431
required for "isabelle build", for example.
wenzelm@48693
  1432
wenzelm@50646
  1433
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  1434
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  1435
wenzelm@50646
  1436
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  1437
INCOMPATIBILITY.
wenzelm@50646
  1438
wenzelm@48844
  1439
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  1440
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  1441
version of Isabelle.
wenzelm@48844
  1442
wenzelm@50646
  1443
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
  1444
platform family: "linux", "macos", "windows".
wenzelm@50646
  1445
wenzelm@50646
  1446
* The ML system is configured as regular component, and no longer
wenzelm@50646
  1447
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  1448
for home-made settings.
wenzelm@50132
  1449
wenzelm@50701
  1450
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  1451
wenzelm@48206
  1452
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  1453
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  1454
configuration.
wenzelm@48206
  1455
wenzelm@48574
  1456
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  1457
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  1458
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  1459
settings manually, or use a Proof General version that has been
wenzelm@48574
  1460
bundled as Isabelle component.

wenzelm@45593
  1467
*** General ***
wenzelm@45593
  1468
wenzelm@45614
  1469
* Prover IDE (PIDE) improvements:
wenzelm@45614
  1470
wenzelm@47585
  1471
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  1472
    command-line needs to be typed into the source buffer)
wenzelm@45614
  1473
  - markup for bound variables
wenzelm@47806
  1474
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  1475
  - support for user-defined Isar commands within the running session
wenzelm@47158
  1476
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  1477
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  1478
wenzelm@47806
  1479
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  1480
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  1481
commands to be used in the same theory where defined.
wenzelm@46485
  1482
wenzelm@47482
  1483
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  1484
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  1485
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  1486
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  1487
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  1488
wenzelm@47482
  1489
  context
wenzelm@47482
  1490
    fixes x y z :: 'a
wenzelm@47482
  1491
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  1492
  begin
wenzelm@47482
  1493
wenzelm@47482
  1494
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  1495
wenzelm@47482
  1496
  end
wenzelm@47482
  1497
wenzelm@47482
  1498
  thm my_trans
wenzelm@47482
  1499
wenzelm@47482
  1500
The most basic application is to factor-out context elements of
wenzelm@47482
  1501
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  1502
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  1503
wenzelm@47482
  1504
Any other local theory specification element works within the "context
wenzelm@47482
  1505
... begin ... end" block as well.
wenzelm@47482
  1506
wenzelm@47484
  1507
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  1508
given name in the context.  These may be later included in other
wenzelm@47484
  1509
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  1510
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  1511
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  1512
wenzelm@47829
  1513
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  1514
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  1515
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  1516
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  1517
indices of schematic variables.
wenzelm@47829
  1518
wenzelm@47829
  1519
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  1520
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  1521
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  1522
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  1523
etc. was exploited.
wenzelm@47829
  1524
wenzelm@47829
  1525
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  1526
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  1527
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  1528
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  1529
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  1530
of the material of that old tutorial.
wenzelm@47829
  1531
wenzelm@47829
  1532
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  1533
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  1534
manual.

wenzelm@47829
  1537
*** Pure ***
wenzelm@47829
  1538
wenzelm@46976
  1539
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  1540
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  1541
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  1542
wenzelm@47855
  1543
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  1544
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  1545
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  1546
undocumented feature.)
wenzelm@47855
  1547
wenzelm@47856
  1548
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  1549
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  1550
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  1551
wenzelm@47856
  1552
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  1553
wenzelm@47856
  1554
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  1555
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  1556
wenzelm@47856
  1557
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  1558
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  1559
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  1560
order to accommodate newly introduced premises.)
wenzelm@47856
  1561
wenzelm@47806
  1562
* Renamed some inner syntax categories:
wenzelm@47806
  1563
wenzelm@47806
  1564
    num ~> num_token
wenzelm@47806
  1565
    xnum ~> xnum_token
wenzelm@47806
  1566
    xstr ~> str_token
wenzelm@47806
  1567
wenzelm@47806
  1568
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  1569
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  1570
position information via constraints).
wenzelm@47806
  1571
wenzelm@47829
  1572
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  1573
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  1574
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  1575
wenzelm@47856
  1576
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  1577
in parse trees are always annotated by position constraints.
wenzelm@45134
  1578
wenzelm@47464
  1579
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  1580
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  1581
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  1582
wenzelm@47464
  1583
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  1584
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  1585
wenzelm@47464
  1586
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  1587
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  1588
haftmann@46028
  1589
  definition [code_abbrev]: "f = t"
haftmann@46028
  1590
haftmann@46028
  1591
INCOMPATIBILITY.
wenzelm@45383
  1592
wenzelm@47856
  1593
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  1594
instead.  INCOMPATIBILITY.
wenzelm@47856
  1595
wenzelm@47856
  1596
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  1597
collection of foundational premises in the context (already marked as
wenzelm@47856
  1598
legacy since Isabelle2011).

wenzelm@47464
  1604
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  1605
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  1606
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  1607
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  1608
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  1609
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  1610
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  1611
possible.
wenzelm@47855
  1612
wenzelm@47855
  1613
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  1614
planning step is necessary to determine what should become a predicate
wenzelm@47464
  1615
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  1616
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  1617
wenzelm@47855
  1618
* Code generation by default implements sets as container type rather
wenzelm@47855
  1619
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  1620
wenzelm@47855
  1621
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
  1622
wenzelm@47464
  1623
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  1624
represents strictly positive binary numerals, along with functions
wenzelm@47464
  1625
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  1626
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  1627
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  1628
user theories may require adaptations as follows:
huffman@47108
  1629
huffman@47108
  1630
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  1631
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  1632
huffman@47108
  1633
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  1634
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  1635
    after classes one and semigroup_add have been instantiated.
huffman@47108
  1636
huffman@47108
  1637
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  1638
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  1639
huffman@47108
  1640
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  1641
    automatically support numerals now, so more simp rules and
huffman@47108
  1642
    simprocs may now apply within the proof.
huffman@47108
  1643
huffman@47108
  1644
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
  1645
    Redefine using other integer operations.
huffman@47108
  1646
wenzelm@47855
  1647
* Transfer: New package intended to generalize the existing
wenzelm@47855
  1648
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  1649
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  1650
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  1651
corresponding parts of the Quotient package.)
wenzelm@47809
  1652
wenzelm@47809
  1653
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  1654
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  1655
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  1656
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  1657
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  1658
wenzelm@47809
  1659
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  1660
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  1661
wenzelm@47809
  1662
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  1663
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  1664
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  1665
    Goals are generalized over all free variables by default; this is
huffman@47851
  1666
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  1667
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  1668
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  1669
    is logically stronger (rather than equivalent).
wenzelm@47809
  1670
wenzelm@47809
  1671
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  1672
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  1673
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  1674
    non-polymorphic constants on the fly.
wenzelm@47809
  1675
wenzelm@47809
  1676
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  1677
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  1678
    constants that already have transfer rules. It should be applied
wenzelm@47809
  1679
    after unfolding the constant definitions.

wenzelm@47809
  1682
    from type nat to type int.
wenzelm@47809
  1683
huffman@47851
  1684
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  1685
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  1686
wenzelm@47809
  1687
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  1688
    terms of a corresponding operation on a representation
wenzelm@47809
  1689
    type.  Example syntax:
wenzelm@47809
  1690
wenzelm@47809
  1691
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  1692
      is List.insert
wenzelm@47809
  1693
wenzelm@47809
  1694
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  1695
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  1696
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  1697
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  1698
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  1699
    by the package.
wenzelm@47809
  1700
wenzelm@47809
  1701
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  1702
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  1703
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  1704
    code generation for each constant.
wenzelm@47809
  1705
wenzelm@47809
  1706
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  1707
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  1708
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  1709
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  1710
    lift_definition command to work with the type.
wenzelm@47809
  1711
wenzelm@47809
  1712
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  1713
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  1714
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  1715
wenzelm@47809
  1716
* Quotient package:
wenzelm@47809
  1717
wenzelm@47809
  1718
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  1719
    rep and abs functions, similar to typedef.
wenzelm@47809
  1720
wenzelm@47809
  1721
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  1722
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  1723
wenzelm@47809
  1724
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  1725
    respectfulness property at the point where the constant is
wenzelm@47809
  1726
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  1727
wenzelm@47809
  1728
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  1729
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  1730
wenzelm@47809
  1731
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  1732
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  1733
wenzelm@47809
  1734
* Quickcheck:
wenzelm@47809
  1735
wenzelm@47809
  1736
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  1737
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  1738
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  1739
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  1740
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  1741
wenzelm@47809
  1742
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  1743
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  1744
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  1745
wenzelm@47809
  1746
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  1747
    continues searching for genuine ones.
wenzelm@47809
  1748
wenzelm@47809
  1749
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  1750
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  1751
    show genuine counterexamples.
wenzelm@47809
  1752
wenzelm@47809
  1753
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  1754
    value generators for a given type and operations.
wenzelm@47809
  1755
wenzelm@47809
  1756
    It generates values by using the operations as if they were
wenzelm@47809
  1757
    constructors of that type.
wenzelm@47809
  1758
wenzelm@47809
  1759
  - Support for multisets.
wenzelm@47809
  1760
wenzelm@47809
  1761
  - Added "use_subtype" options.
wenzelm@47809
  1762
wenzelm@47809
  1763
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  1764
    conjectures in a locale context.
wenzelm@47809
  1765
wenzelm@47855
  1766
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  1767
and affecting 'rat' and 'real'.
wenzelm@47809
  1768
wenzelm@47809
  1769
* Sledgehammer:
wenzelm@47809
  1770
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  1771
    paper "More SPASS with Isabelle".
wenzelm@47809
  1772
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  1773
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  1774
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  1775
  - Sped up the minimizer.
wenzelm@47809
  1776
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  1777
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  1778
  - Renamed "sound" option to "strict".
wenzelm@47809
  1779
wenzelm@47855
  1780
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  1781
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  1782
wenzelm@47855
  1783
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  1784
wenzelm@47855
  1785
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  1786
wenzelm@47856
  1787
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  1788
case distinctions at the same time.  E.g.
wenzelm@47856
  1789
wenzelm@47856
  1790
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  1791
wenzelm@47856
  1792
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  1793
a list and a nat.
wenzelm@47856
  1794
wenzelm@47809
  1795
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  1796
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  1797
wenzelm@47702
  1798
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  1799
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  1800
default.
wenzelm@47702
  1801
wenzelm@47856
  1802
* Record: code generation can be switched off manually with
wenzelm@47856
  1803
wenzelm@47856
  1804
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
  1805
wenzelm@47856
  1806
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
  1807
wenzelm@47855
  1808
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
  1809
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
  1810
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
  1811
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
  1812
one_case.
wenzelm@47855
  1813
wenzelm@47855
  1814
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
  1815
the result of the fact expression.
wenzelm@47855
  1816
haftmann@46752
  1817
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
  1818
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
  1819

wenzelm@47464
  1830
See theory "Relation" for examples for making use of pred/set
wenzelm@47464

haftmann@46752
  1833
INCOMPATIBILITY.
haftmann@46752
  1834
bulwahn@46363

* Theory Relation: Consolidated constant name for relation composition
wenzelm@47464
  1866
and corresponding theorem names:
wenzelm@47464
  1867
haftmann@47549
  1868
  - Renamed constant rel_comp to relcomp.
wenzelm@47464

* Session HOL-Word: New proof method "word_bitwise" for splitting
wenzelm@47809
  2271
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  2272
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  2273
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  2274
constants.  Requires fixed-length word types, not 'a word.  Solves
wenzelm@47854
  2275
many standard word identities outright and converts more into first
wenzelm@47809
  2276
order problems amenable to blast or similar.  See also examples in

* Session HOL-Probability: Introduced the type "'a measure" to
wenzelm@47807
  2280
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807
  2281
measure_space.  The locales based on subset_class now have two
wenzelm@47856
  2282
locale-parameters the space \<Omega> and the set of measurable sets M.
wenzelm@47856
  2283
The product of probability spaces uses now the same constant as the
wenzelm@47856
  2284
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  2285
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  2286
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  2287
Measure space constructions for distributions and densities now got
wenzelm@47807
  2288
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  2289
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  2290
and point_measure is introduced.  INCOMPATIBILITY.

wenzelm@46992
  2482
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992

wenzelm@46992
  2484
non-empty name (used for the foundation in the background theory),
wenzelm@46992
  2485
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
  2486
INCOMPATIBILITY for derived definitional packages: need to specify

  2487
naming policy for primitive definitions more explicitly.
wenzelm@46916
  2488
wenzelm@46497

conformance with similar operations in structure Term and Logic.
wenzelm@46497
  2491
wenzelm@45592

* USER_HOME settings variable points to cross-platform user home
wenzelm@47661
  2522
directory, which coincides with HOME on POSIX systems only.  Likewise,
wenzelm@47661
  2523
the Isabelle path specification "~" now expands to $USER_HOME, instead
wenzelm@47661
  2524
of former $HOME.  A different default for USER_HOME may be set
wenzelm@47661
  2525
explicitly in shell environment, before Isabelle settings are
wenzelm@47661
  2526
evaluated.  Minor INCOMPATIBILITY: need to adapt Isabelle path where
wenzelm@47661
  2527
the generic user home was intended.
wenzelm@47661
  2528
wenzelm@47807
  2529
* ISABELLE_HOME_WINDOWS refers to ISABELLE_HOME in windows file name

  2530
notation, which is useful for the jEdit file browser, for example.
wenzelm@47807

  2543
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760

wenzelm@44777
  2545
  - Management of multiple theory files directly from the editor
wenzelm@44760
  2546
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
  2547
    files for checking).
wenzelm@44760
  2548
wenzelm@44777
  2549
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
  2550
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
  2551
    positions.
wenzelm@44760
  2552
wenzelm@44777
  2553
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
  2554
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
  2555
    theory output and other non-Isabelle text boxes).
wenzelm@44777
  2556
wenzelm@44777
  2557
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
  2558
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
  2559
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
  2560
wenzelm@44777
  2561
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
  2562
    cores.
wenzelm@44760
  2563
wenzelm@44777
  2564
  - Reduced memory requirements due to pruning of unused document

  2565
    versions (garbage collection).

  2568
including some remaining limitations.

* Theory loader: source files are exclusively located via the master
wenzelm@44800
  2571
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
  2572
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
  2573
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
  2574
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
  2575
INCOMPATIBILITY.
wenzelm@44800
  2576
wenzelm@41955
  2577
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
  2578
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
  2579
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
  2580
wenzelm@41703

Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
  2583
usedir option -Q.
wenzelm@41703
  2584
wenzelm@42669
  2585
* Name space: former unsynchronized references are now proper
wenzelm@42669
  2586
configuration options, with more conventional names:
wenzelm@42669
  2587
wenzelm@42669
  2588
  long_names   ~> names_long
wenzelm@42669
  2589

  2590
  unique_names ~> names_unique
wenzelm@42669
  2591
wenzelm@42669
  2592
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
  2593
wenzelm@42669
  2594
  declare [[names_unique = false]]
wenzelm@42358
  2595
wenzelm@42502
  2596
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  2597
that the result needs to be unique, which means fact specifications
wenzelm@42502
  2598
may have to be refined after enriching a proof context.
wenzelm@42502
  2599
wenzelm@44800
  2600
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  2601
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  2602
wenzelm@44968
  2603
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  2604
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  2605
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
  2606

compl_sup_top, inf_idem, inf_left_idem, inf_sup_absorb, sup_idem,
wenzelm@44973

krauss@44845
  2673
* Added syntactic classes "inf" and "sup" for the respective
krauss@44845
  2674
constants.  INCOMPATIBILITY: Changes in the argument order of the
krauss@44845
  2675
(mostly internal) locale predicates for some derived classes.

wenzelm@44800
  2679
UN_ball_bex_simps.  INCOMPATIBILITY.
wenzelm@44800

separate type class floor_ceiling.
wenzelm@44800
  2683
wenzelm@44800

  2690
adjustment.  INCOMPATIBILITY.
haftmann@42874

accordance with standard mathematical terminology. INCOMPATIBILITY.
huffman@44081
  2694
wenzelm@44800
  2695
* Theory Complex_Main: The locale interpretations for the
wenzelm@44800
  2696
bounded_linear and bounded_bilinear locales have been removed, in
wenzelm@44800
  2697
order to reduce the number of duplicate lemmas. Users must use the
wenzelm@44800
