*** General ***
wenzelm@54702
     8
wenzelm@57452
     9
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
    10
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
    11
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
    12
environment is restricted to the Standard ML implementation of
wenzelm@57452
    13
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
    14
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
    15
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
    16
some examples.
wenzelm@56499
    17
wenzelm@56232
    18
* More static checking of proof methods, which allows the system to
wenzelm@56232
    19
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
    20
processed in the original proof context as far as possible, before
wenzelm@56232
    21
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
    22
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
    23
number that is out of range produces an empty result sequence, not an
wenzelm@56232
    24
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
    25
proof tools.
wenzelm@56232
    26
wenzelm@57452
    27
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
    28
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
    29
supports input via ` (backquote).
wenzelm@57452
    30
wenzelm@57452
    31
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
    32
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
    33
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
    34
wenzelm@57452
    35
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
    36
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
    37
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
    38
Minor INCOMPATIBILITY.
wenzelm@57452
    39
wenzelm@57452
    40
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
    41
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
    42
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
    43
INCOMPATIBILITY.
wenzelm@57452
    44
wenzelm@57452
    45
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
    46
which results in an active hyperlink within the text.
wenzelm@57452
    47
wenzelm@57452
    48
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
    49
not check existence within the file-system.
wenzelm@57452
    50
wenzelm@57452
    51
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
    52
isar-ref, jedit, system.
wenzelm@57423
    53
wenzelm@54702
    54
wenzelm@54533
    55
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
    56
wenzelm@57452
    57
* Improved Document panel: simplied interaction where every single
wenzelm@57452
    58
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
    59
buffer.
wenzelm@57452
    60
wenzelm@57452
    61
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
    62
to PIDE hyperlinks.
wenzelm@57452
    63
wenzelm@57452
    64
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
    65
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
    66
wenzelm@57452
    67
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
    68
auxiliary ML files.
wenzelm@57423
    69
wenzelm@57423
    70
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
    71
templates, completion language context, name-space completion,
wenzelm@57423
    72
file-name completion, spell-checker completion.
wenzelm@57423
    73
wenzelm@57423
    74
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
    75
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
    76
keystrokes with slow / remote graphics displays.
wenzelm@57423
    77
wenzelm@57423
    78
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
    79
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
    80
caret".
wenzelm@56342
    81
wenzelm@56580
    82
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
    83
completion popup and context-menu.
wenzelm@56554
    84
wenzelm@56879
    85
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
    86
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
    87
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
    88
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
    89
wenzelm@56901
    90
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
    91
to highlight text via regular expression.
wenzelm@56901
    92
wenzelm@54881
    93
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
    94
General") allows to specify additional print modes for the prover
wenzelm@54881
    95
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
    96
"isabelle jedit -m MODE".
wenzelm@54881
    97
wenzelm@56505
    98
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
    99
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   100
wenzelm@56838
   101
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   102
more robust treatment of threads and interrupts.
wenzelm@56838
   103
wenzelm@56939
   104
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   105
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   106
"Detach" a copy where this makes sense.
wenzelm@56939
   107
wenzelm@57452
   108
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57452
   109
simplification process, enabled by the "simplifier_trace" attribute
wenzelm@57452
   110
within the context.
wenzelm@57452
   111
wenzelm@57452
   112
wenzelm@54533
   113
wenzelm@55001
   114
*** Pure ***
wenzelm@55001
   115
wenzelm@56245
   116
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   117
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   118
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   119
renaming needs to be applied:
wenzelm@56245
   120
wenzelm@56245
   121
  ==             ~>  Pure.eq
wenzelm@56245
   122
  ==>            ~>  Pure.imp
wenzelm@56245
   123
  all            ~>  Pure.all
wenzelm@56245
   124
  TYPE           ~>  Pure.type
wenzelm@56245
   125
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   126
wenzelm@56245
   127
Systematic porting works by using the following theory setup on a
wenzelm@56245
   128
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   129
old constants:
wenzelm@56245
   130
wenzelm@56245
   131
setup {*
wenzelm@56245
   132
  fn thy => thy
wenzelm@56245
   133
    |> Sign.root_path
wenzelm@56245
   134
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   135
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   136
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   137
    |> Sign.restore_naming thy
wenzelm@56245
   138
*}
wenzelm@56245
   139
wenzelm@56245
   140
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   141
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   142
the auxiliary aliases are deleted.
wenzelm@56245
   143
wenzelm@55385
   144
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@55385
   145
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@55385
   146
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57452
   147
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57452
   148
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57452
   149
finished trivially if the underlying class definition is made vacuous
wenzelm@57452
   150
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57452
   151
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57452
   152
Axclass.arity_axiomatization.
wenzelm@55385
   153
wenzelm@55143
   154
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   155
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   156
instantiated theorem.
wenzelm@55143
   157
wenzelm@55152
   158
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
   159
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
   160
where instantiations with schematic variables are intended (for
wenzelm@55152
   161
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
   162
following temporary definition may help to port old applications:
wenzelm@55152
   163
wenzelm@55152
   164
  attribute_setup standard =
wenzelm@55152
   165
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
   166
wenzelm@55001
   167
* More thorough check of proof context for goal statements and
wenzelm@55006
   168
attributed fact expressions (concerning background theory, declared
wenzelm@55006
   169
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
   170
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
   171
primitive Thm.assume_hyps.
wenzelm@55001
   172
wenzelm@55108
   173
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
   174
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
   175
differently, e.g. via cartouches).
wenzelm@57452
   176
wenzelm@57452
   177
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
   178
per-constant basis.  See attribute "code_preproc".
haftmann@57430
   179
wenzelm@57415
   180
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57415
   181
but the latter is retained some time as Proof General legacy.
wenzelm@57415
   182
wenzelm@55001
   183
haftmann@54227
   184
*** HOL ***
haftmann@54227
   185
haftmann@57437
   186
* Qualified String.implode and String.explode.  INCOMPATIBILITY.
haftmann@57437
   187
wenzelm@57452
   188
* Command and antiquotation "value" are now hardcoded against nbe and
wenzelm@57452
   189
ML.  Minor INCOMPATIBILITY.
wenzelm@57452
   190
wenzelm@57452
   191
* Separate command "approximate" for approximative computation in
wenzelm@57452
   192
src/HOL/Decision_Procs/Approximation.  Minor INCOMPATIBILITY.
haftmann@56923
   193
haftmann@56807
   194
* Adjustion of INF and SUP operations:
wenzelm@57452
   195
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57452
   196
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57452
   197
    SUP instead uniformly.
wenzelm@57452
   198
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57452
   199
    or SUP and Sup.
wenzelm@57452
   200
  - INF_image and SUP_image do not unfold composition.
wenzelm@57452
   201
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57452
   202
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57452
   203
    simplifier implication in premises.  Generalize and replace former
wenzelm@57452
   204
    INT_cong, SUP_cong
wenzelm@57452
   205
haftmann@56166
   206
INCOMPATIBILITY.
haftmann@56166
   207
lp15@57474
   208
* Revisions to HOL/Number_Theory
lp15@57474
   209
  - consolidated the proofs of the binomial theorem
lp15@57474
   210
  - the function fib is again of type nat=>nat and not overloaded
lp15@57474
   211
  - no more references to Old_Number_Theory in the HOL libraries (except the AFP)
lp15@57474
   212
lp15@57474
   213
INCOMPATIBILITY.
lp15@57474
   214
haftmann@56154
   215
* Swapped orientation of facts image_comp and vimage_comp:
wenzelm@57452
   216
haftmann@56154
   217
  image_compose ~> image_comp [symmetric]
haftmann@56154
   218
  image_comp ~> image_comp [symmetric]
haftmann@56154
   219
  vimage_compose ~> vimage_comp [symmetric]
haftmann@56154
   220
  vimage_comp ~> vimage_comp [symmetric]
wenzelm@57452
   221
wenzelm@57452
   222
INCOMPATIBILITY.
wenzelm@57452
   223
wenzelm@57452
   224
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
   225
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
   226
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
   227
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
   228
again in the future.  INCOMPATIBILITY.
nipkow@56073
   229
haftmann@55818
   230
* HOL-Word:
wenzelm@57452
   231
  - Abandoned fact collection "word_arith_alts", which is a duplicate
wenzelm@57452
   232
    of "word_arith_wis".
wenzelm@57452
   233
  - Dropped first (duplicated) element in fact collections
wenzelm@57452
   234
    "sint_word_ariths", "word_arith_alts", "uint_word_ariths",
wenzelm@57452
   235
    "uint_word_arith_bintrs".
wenzelm@57452
   236
wenzelm@57452
   237
* Code generator: enforce case of identifiers only for strict target
wenzelm@57452
   238
language requirements.  INCOMPATIBILITY.
haftmann@56826
   239
haftmann@55757
   240
* Code generator: explicit proof contexts in many ML interfaces.
haftmann@55757
   241
INCOMPATIBILITY.
haftmann@55757
   242
wenzelm@57452
   243
* Code generator: minimize exported identifiers by default.  Minor
wenzelm@57452
   244
INCOMPATIBILITY.
wenzelm@57452
   245
wenzelm@57452
   246
* Code generation for SML and OCaml: dropped arcane "no_signatures"
wenzelm@57452
   247
option.  Minor INCOMPATIBILITY.
haftmann@55677
   248
wenzelm@55139
   249
* Simproc "finite_Collect" is no longer enabled by default, due to
wenzelm@55139
   250
spurious crashes and other surprises.  Potential INCOMPATIBILITY.
wenzelm@55139
   251
wenzelm@57452
   252
* Moved new (co)datatype package and its dependencies from session
wenzelm@57452
   253
  "HOL-BNF" to "HOL".  The commands 'bnf', 'wrap_free_constructors',
wenzelm@57452
   254
  'datatype_new', 'codatatype', 'primcorec', 'primcorecursive' are now
wenzelm@57452
   255
  part of theory "Main".

* New (co)datatype package:
wenzelm@57452
   295
  - Command 'primcorec' is fully implemented.
wenzelm@57452
   296
  - Command 'datatype_new' generates size functions ("size_xxx" and

* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57452
   442
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57452
   443
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57452
   444
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57452
   445
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57452
   446
corresponding tactics; the old default can be restored using "declare

   450
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57452
   451
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57452
   452
supported as oracles. Yices is no longer supported, because no version
wenzelm@57452
   453
of the solver can handle both SMT-LIB 2 and quantifiers.
blanchet@56118
   454
blanchet@55183

* Sledgehammer:
blanchet@57246
   456
  - Z3 can now produce Isar proofs.
blanchet@57020
   457
  - MaSh overhaul:
wenzelm@57452
   458
    . New SML-based learning engines eliminate the dependency on
wenzelm@57452
   459
      Python and increase performance and reliability.
wenzelm@57452
   460
    . MaSh and MeSh are now used by default together with the
wenzelm@57452
   461
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57452
   462
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin

select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622

order of reports given by the prover: later markup is usually more
wenzelm@55622
   908
specific and may override results accumulated so far.  The elements

guard is mandatory and checked precisely.  Subtle INCOMPATIBILITY.

structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
   919
wenzelm@56279
   920
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
   921
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
   922
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
   923
wenzelm@56281
   924
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
   925
INCOMPATIBILITY.
wenzelm@56281
   926
wenzelm@56281
   927
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
   928
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
   929
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
   930
INCOMPATIBILITY.
wenzelm@56279
   931
wenzelm@55143
   932
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@55143
   933
variables that are meant to become schematic need to be given as
wenzelm@55143
   934
fixed, and are generalized by the explicit context of local variables.
wenzelm@55143
   935
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@55143
   936
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@55143
   937
of schematic variables.
wenzelm@55143
   938
wenzelm@54449
   939
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
   940
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
   941
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
   942
formal context.
wenzelm@54449
   943
wenzelm@54742
   944
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@54742
   945
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@54742
   946
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@54742
   947
actually belongs to it).
wenzelm@54742
   948
wenzelm@55549
   949
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@55549
   950
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@55549
   951
current background theory.  Thus equivalent data produced in different
wenzelm@55549
   952
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@55549
   953
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@55549
   954
appropriate than Thm.eq_thm.
wenzelm@55549
   955
wenzelm@56205
   956
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
   957
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
   958
wenzelm@56071
   959
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
   960
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
   961
wenzelm@56135
   962
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
   963
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
   964
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
   965
well-defined master directory, so an absolute symbolic path
wenzelm@56135
   966
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
   967
wenzelm@56399
   968
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
   969
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
   970
purposes.

Isabelle component, e.g. ProofGeneral-4.2-2 from the Isabelle
wenzelm@57443
   977
component repository http://isabelle.in.tum.de/components/.  See also

notably those that are not bundled with the normal release.
wenzelm@57443
   980
wenzelm@56439
   981
* The raw Isabelle process executable has been renamed from
wenzelm@56439
   982
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
   983
shell naming conventions, and allows to define a shell function within
wenzelm@56439
   984
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@56439
   985
incompatibility for old tools that do not use the $ISABELLE_PROCESS

wenzelm@57439
   989
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
   990
obsolete Isar TTY loop.
wenzelm@57439
   991
wenzelm@57452
   992
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
   993
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
   994
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
   995
via desktop environment, without any special precautions.  Potential
wenzelm@57452
   996
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
   997
wenzelm@57413
   998
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
   999
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1000
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1001
wenzelm@57452
  1002

integrated into Isabelle/jEdit eventually.

$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1008
wenzelm@57084

* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57084
  1010
of TeX Live from Cygwin.
wenzelm@57084
  1011
wenzelm@57452
  1012
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1013
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1014
files are copied to the document output directory, before document
wenzelm@57452
  1015
processing is started.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54639
  1023
wenzelm@54639
  1024
* More robust editing of running commands with internal forks,
wenzelm@54639
  1025
e.g. non-terminating 'by' steps.
wenzelm@54639
  1026
wenzelm@54641
  1027
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
  1028
after edits surrounding the command location.
wenzelm@54641
  1029
wenzelm@54648
  1030
* More status information about commands that are interrupted
wenzelm@54648
  1031
accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
  1032
e.g. out-of-memory).

*** System ***
wenzelm@54653
  1036
wenzelm@54653
  1037
* More robust termination of external processes managed by
wenzelm@54664
  1038
Isabelle/ML: support cancellation of tasks within the range of
wenzelm@54664
  1039
milliseconds, as required for PIDE document editing with automatically
wenzelm@54664
  1040
tried tools (e.g. Sledgehammer).
wenzelm@54653
  1041
wenzelm@54648
  1042
* Reactivated Isabelle/Scala kill command for external processes on
wenzelm@54648
  1043
Mac OS X, which was accidentally broken in Isabelle2013-1 due to a
wenzelm@54648
  1044
workaround for some Debian/Ubuntu Linux versions from 2013.

wenzelm@51293
  1051
*** General ***
wenzelm@51293
  1052
wenzelm@53971
  1053
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  1054
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  1055
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  1056
wenzelm@53971
  1057
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
  1058
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1059
wenzelm@53016
  1060
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1061
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1062
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1063
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  1064
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1065
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  1066
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1067
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  1068
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  1069
syntax.
wenzelm@53016
  1070
wenzelm@53021
  1071
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  1072
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  1073
wenzelm@52487
  1074
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1075
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1076
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1077
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1078
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1079
wenzelm@52060
  1080
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  1081
INCOMPATIBILITY.
wenzelm@52060
  1082
wenzelm@52430
  1083
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1084
implicit change of some global references) is retained for now as
wenzelm@52430
  1085
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1086
wenzelm@52549
  1087
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1088
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1089
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1090
wenzelm@53971
  1091
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
  1092
eliminated old "ref" manual.

  1095
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
  1096
wenzelm@53971
  1097
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
  1098
Documentation panel.
wenzelm@53852
  1099
wenzelm@53971
  1100
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  1101
documentation.
wenzelm@52646
  1102
wenzelm@52949
  1103
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  1104
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  1105
wenzelm@53050
  1106
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  1107
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  1108
normal editing and checking process.
wenzelm@53050
  1109
wenzelm@51533
  1110
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  1111
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  1112
same timing information is shown in the extended tooltip of the
wenzelm@54332
  1113
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  1114
COMMAND modifier is pressed.
wenzelm@51533
  1115
wenzelm@53971
  1116
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  1117
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  1118
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  1119
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  1120
or shortcut "C+e SPACE".
wenzelm@53971
  1121
wenzelm@54305
  1122
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  1123
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  1124
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  1125
wenzelm@54319
  1126
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  1127
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  1128
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  1129
to resolve conflict.
wenzelm@54319
  1130
wenzelm@54305
  1131
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  1132
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  1133
wenzelm@53971
  1134
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  1135
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  1136
such command executions while editing.
wenzelm@53271
  1137
wenzelm@53971
  1138
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  1139
document content.
wenzelm@53971
  1140
wenzelm@53971
  1141
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  1142
toplevel theorem statements.
wenzelm@53971
  1143
wenzelm@53971
  1144
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  1145
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  1146
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  1147
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  1148
wenzelm@53971
  1149
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  1150
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  1151
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  1152
wenzelm@53971
  1153
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  1154
/ Global Options / Appearance".
wenzelm@53971
  1155
wenzelm@53971
  1156
* Improved support of native Mac OS X functionality via "MacOSX"
wenzelm@53971
  1157
plugin, which is now enabled by default.
wenzelm@53971

  1160
*** Pure ***
wenzelm@51313
  1161
ballarin@54049
  1162
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  1163
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  1164
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  1165
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  1166
details.
haftmann@51747
  1167
ballarin@51565
  1168
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  1169
wenzelm@51313
  1170
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  1171
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  1172
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  1173
wenzelm@51316
  1174
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  1175
INCOMPATIBILITY.
wenzelm@51316
  1176
wenzelm@53971
  1177
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  1178
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  1179
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  1180
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  1181
wenzelm@53971
  1182
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  1183
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  1184
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  1185
wenzelm@53971
  1186
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  1187
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  1188
wenzelm@52463
  1189
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
  1190
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
  1191
situations.

hoelzl@51002
  1194
*** HOL ***
hoelzl@51002
  1195
wenzelm@54032
  1196
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  1197
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  1198
INCOMPATIBILITY.
wenzelm@54032
  1199
wenzelm@54032
  1200
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  1201
wenzelm@54032
  1202
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  1203
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  1204
from the datatype package. The declaration attribute
wenzelm@54032
  1205
"case_translation" can be used to register new case combinators:
wenzelm@54032
  1206
wenzelm@54032
  1207
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  1208
haftmann@52435
  1209
* Code generator:
wenzelm@53160
  1210
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  1211
    'code_instance'.
wenzelm@53160
  1212
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  1213
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  1214
wenzelm@53983
  1215
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  1216
examples.
haftmann@52435
  1217
wenzelm@54032
  1218
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  1219
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  1220
to distinguish both when desired.
wenzelm@54032
  1221
wenzelm@54032
  1222
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  1223
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  1224
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
  1225
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  1226
wenzelm@54032
  1227
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  1228
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  1229
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  1230
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  1231
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  1232
ML).  INCOMPATIBILITY.
wenzelm@54032
  1233
wenzelm@54032
  1234
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  1235
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  1236
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  1237
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  1238
wenzelm@54032
  1239
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  1240
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  1241
wenzelm@54032
  1242
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  1243
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  1244
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
  1245
kuncar@54021
  1246
* Lifting:
kuncar@54021
  1247
  - parametrized correspondence relations are now supported:
wenzelm@54378
  1248
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  1249
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  1250
      transfer rules
kuncar@54021
  1251
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  1252
      correspondence relation can be generated
kuncar@54021
  1253
    + various new properties of the relator must be specified to support
kuncar@54021
  1254
      parametricity
kuncar@54021
  1255
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  1256
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  1257
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  1258
    copies
kuncar@54021
  1259
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  1260
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  1261
    anonymous context)
wenzelm@54378
  1262
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  1263
    Main. Potential INCOMPATIBILITY
kuncar@54021
  1264
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  1265
    lifting_forget, lifting_update
wenzelm@54378
  1266
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  1267
    INCOMPATIBILITY
kuncar@54021
  1268
kuncar@54021
  1269
* Transfer:
wenzelm@54378
  1270
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  1271
    by the actual invariant in a transferred goal
kuncar@54021
  1272
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  1273
  - Experimental support for transferring from the raw level to the
kuncar@54021
  1274
    abstract level: Transfer.transferred attribute
kuncar@54021
  1275
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  1276
haftmann@52286
  1277
* Reification and reflection:
wenzelm@53160
  1278
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  1279
    "Reification".
wenzelm@53160
  1280
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  1281
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  1282
INCOMPATIBILITY.

  1284
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  1285
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  1286
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  1287
    This is now identity on infinite sets.
wenzelm@52745
  1288
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  1289
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  1290
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  1291
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  1292
    See theory Big_Operators for canonical examples.
haftmann@51489
  1293
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  1294
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  1295
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  1296
    those foundational constants as substitutes, but it is
wenzelm@53983
  1297
    preferable to interpret the above locales accordingly.
haftmann@51489
  1298
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  1299
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  1300
  - Fact renames:

      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  1302
      card.union_disjoint ~> card_Un_disjoint

* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  1306
wenzelm@53526
  1307
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  1308
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  1309
class predicate assumption or sort constraint when possible.
Andreas@53362
  1310
INCOMPATIBILITY.
Andreas@53362
  1311
wenzelm@53160
  1312
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  1313
complete lattice but does not assume the existence of the top and
wenzelm@53160
  1314
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  1315
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  1316
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  1317
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  1318
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  1319
lemmas.
wenzelm@53160
  1320
wenzelm@53160
  1321
* Introduce type class linear_continuum as combination of
wenzelm@53160
  1322
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  1323
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  1324
wenzelm@53983
  1325
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  1326
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  1327
Rename bot -> order_bot, top -> order_top
lammich@53683
  1328
wenzelm@53160
  1329
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  1330
top and bottom elements.
hoelzl@51732
  1331
hoelzl@51732
  1332
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  1333
hoelzl@51732
  1334
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  1335
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  1336
wenzelm@53983
  1337
 - Introduce type class (lin)order_topology and
wenzelm@53983
  1338
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  1339
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  1340
hoelzl@51732
  1341
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  1342
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  1343
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  1344
wenzelm@53983
  1345
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  1346
   arbitrary filter.
wenzelm@53983
  1347
wenzelm@53983
  1348
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  1349
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  1350
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  1351
   continuous function is continuous, when the function is continuous
wenzelm@53983
  1352
   on a compact set.
hoelzl@51732
  1353
hoelzl@51732
  1354
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  1355
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  1356
   linear_continuum_topology).
hoelzl@51732
  1357
hoelzl@51732
  1358
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  1359
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  1360
   on all sequences converging to x.
wenzelm@53983
  1361
wenzelm@53983
  1362
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  1363
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  1364
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  1365
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  1366
   left or right.
hoelzl@51732
  1367
hoelzl@51732
  1368
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  1369
hoelzl@51732
  1370
     F within X = inf F (principal X)
hoelzl@51732
  1371
hoelzl@51732
  1372
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  1373
   abbreviation for "at x within UNIV"
hoelzl@51732
  1374
wenzelm@53983
  1375
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  1376
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  1377
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  1378
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  1379
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  1380
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  1381
hoelzl@51732
  1382
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  1383
hoelzl@51732
  1384
   + Moved RealDef and RComplete into Real
hoelzl@51732
  1385
hoelzl@51732
  1386
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  1387
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  1388
hoelzl@51732
  1389
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  1390
wenzelm@53983
  1391
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  1392
     Real_Vector_Spaces, and Limits
hoelzl@51732
  1393
hoelzl@51732
  1394
   + Moved Ln and Log to Transcendental
hoelzl@51732
  1395
hoelzl@51732
  1396
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  1397
hoelzl@51732
  1398
 - Remove various auxiliary lemmas.

blanchet@55889
  1411
  - Better support for "isar_proofs".
blanchet@55889
  1412
  - MaSh has been fined-tuned and now runs as a local server.
blanchet@51137
  1413
wenzelm@54032
  1414
* Improved support for ad hoc overloading of constants (see also
wenzelm@54032

isar-ref manual and ~~/src/HOL/ex/Adhoc_Overloading_Examples.thy).
wenzelm@54032
  1416
wenzelm@54032
  1417
* Library/Polynomial.thy:
wenzelm@54032
  1418
  - Use lifting for primitive definitions.
wenzelm@54032
  1419
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
  1420
    generated code.
wenzelm@54032
  1421
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
  1422
  - Prefer pre-existing gcd operation for gcd.
wenzelm@54032
  1423
  - Fact renames:

* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
wenzelm@54032
  1430
case_of_simps to convert function definitions between a list of

* Discontinued theory src/HOL/Library/Eval_Witness.  INCOMPATIBILITY.
wenzelm@54032
  1438
wenzelm@54032

* Consolidation of library theories on product orders:
wenzelm@54032
  1440
wenzelm@54032
  1441
    Product_Lattice ~> Product_Order -- pointwise order on products
wenzelm@54032

  1448
instead, or import theory Legacy_Mrec as a fallback.
wenzelm@53160
  1449
wenzelm@53983
  1450
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
  1451
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983
  1452
~~/src/HOL/Library/Polynomial instead.  The latter provides
wenzelm@53983
  1453
integration with HOL's type classes for rings.  INCOMPATIBILITY.

* HOL-BNF:
wenzelm@54032
  1456
  - Various improvements to BNF-based (co)datatype package, including

  1457
    new commands "primrec_new", "primcorec", and
wenzelm@54032
  1458
    "datatype_new_compat", as well as documentation. See

  1459
    "datatypes.pdf" for details.
wenzelm@54032
  1460
  - New "coinduction" method to avoid some boilerplate (compared to
wenzelm@54032
  1461
    coinduct).
wenzelm@54032
  1462

*** ML ***
wenzelm@51551
  1477
wenzelm@53971
  1478
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  1479
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
  1480
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its

  1481
Examples.thy in particular.
wenzelm@53971
  1482
wenzelm@53709
  1483
* Improved printing of exception trace in Poly/ML 5.5.1, with regular

wenzelm@53971
  1489
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
  1490

historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
  1503
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
  1504
retains its use as snapshot of the main Simplifier context, using

  1505
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717

* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  1510
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971

*** General ***
wenzelm@47967
  1559
wenzelm@50126
  1560
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  1561
no longer printed by default, since it is incompatible with
wenzelm@50126
  1562
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  1563
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  1564
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  1565
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  1566
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  1567
wenzelm@49699
  1568
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  1569
into the printed representation of formal entities --- notably type
wenzelm@49699
  1570
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  1571
information via tooltips in the output window, for example.
wenzelm@49699
  1572
wenzelm@48890
  1573
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  1574
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  1575
wenzelm@49243
  1576
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  1577
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  1578
Tools that load their additional source files may imitate the
wenzelm@49243
  1579
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  1580
dependencies properly.
wenzelm@49243
  1581
wenzelm@47967
  1582
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  1583
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  1584
wenzelm@50110
  1585
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  1586
remaining material in old "ref" manual.
wenzelm@48120
  1587
wenzelm@51050
  1588
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  1589
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  1590
and "class ... context ...".
wenzelm@49841
  1591
wenzelm@50772
  1592
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  1593
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  1594
the target context.  This form of declaration is stable when exported
wenzelm@50772
  1595
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  1596
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  1597
in HOL/inductive and HOL/function.
wenzelm@50772
  1598
wenzelm@49869
  1599
* More informative error messages for Isar proof commands involving
wenzelm@49869
  1600
lazy enumerations (method applications etc.).
wenzelm@49869
  1601
wenzelm@50213
  1602
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  1603
to name patterns (with clickable results).
wenzelm@50213
  1604
wenzelm@47967
  1605
wenzelm@49968
  1606
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  1607
wenzelm@49968
  1608
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  1609
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  1610
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  1611
surface, while the prover is still crunching on internal
wenzelm@49968
  1612
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  1613
required to complete full proof checking eventually.
wenzelm@49968
  1614
wenzelm@49968
  1615
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  1616
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  1617
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  1618
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  1619
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  1620
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  1621
wenzelm@50717
  1622
* Improved support for commands that produce graph output: the text
wenzelm@50717
  1623
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  1624
browser on demand.
wenzelm@50717
  1625
wenzelm@49968
  1626
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  1627
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  1628
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  1629
that frequently occur in user interaction.
wenzelm@49968
  1630
wenzelm@49968
  1631
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  1632
files.  More scalable management of formal document content.
wenzelm@49968
  1633
wenzelm@50505
  1634
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  1635
certain number of messages per command transaction, with some user
wenzelm@50505
  1636
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  1637
potentially infinite message streams.
wenzelm@49968
  1638
wenzelm@49968
  1639
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  1640
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  1641
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  1642
schemes.
wenzelm@49968
  1643
wenzelm@50184
  1644
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  1645
symbols.
wenzelm@50184
  1646
wenzelm@51082
  1647
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  1648
continuous display of the chart slows down the system.
wenzelm@50701
  1649
wenzelm@50183
  1650
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  1651
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  1652
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  1653
wenzelm@50198
  1654
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  1655
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  1656
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  1657
need to be adapted to local keyboard layouts.
wenzelm@50183
  1658
wenzelm@50730
  1659
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  1660
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  1661
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  1662
wenzelm@50406
  1663
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  1664
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  1665
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  1666
Isabelle distribution.
wenzelm@50406
  1667
wenzelm@49968
  1668
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  1669
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  1670
now bundled exclusively with Isabelle.

wenzelm@48205
  1674
haftmann@48431
  1675
* Code generation for Haskell: restrict unqualified imports from
haftmann@48431
  1676
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
  1677
wenzelm@50646
  1678
* Command 'export_code': relative file names are interpreted
wenzelm@50646
  1679
relatively to master directory of current theory rather than the
wenzelm@50646
  1680
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
  1681
wenzelm@48205
  1682
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  1683
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  1684
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  1685
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  1686
with some care where this is really required.
wenzelm@48205
  1687
wenzelm@48792
  1688
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  1689
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  1690
given sort.  Example (in HOL):
wenzelm@48792
  1691
wenzelm@48792
  1692
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
  1693
wenzelm@50716
  1694
* Command 'locale_deps' visualizes all locales and their relations as
wenzelm@50716
  1695
a Hasse diagram.

wenzelm@50646
  1700
* Sledgehammer:
wenzelm@50646
  1701
wenzelm@50646
  1702
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
  1703
    Sledgehammer manual for details.
wenzelm@50646
  1704
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
  1705
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
  1706
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
  1707
  - Renamed options:
wenzelm@50646
  1708
      isar_proof ~> isar_proofs
wenzelm@50646
  1709
      isar_shrink_factor ~> isar_shrink
wenzelm@50646
  1710
      max_relevant ~> max_facts
wenzelm@50646
  1711
      relevance_thresholds ~> fact_thresholds
wenzelm@50646
  1712
wenzelm@50646
  1713
* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
  1714
switched on by default, and can be switched off by setting the
wenzelm@50646
  1715
configuration quickcheck_optimise_equality to false.
wenzelm@50646
  1716
kuncar@50878

* Quotient: only one quotient can be defined by quotient_type
kuncar@50878
  1718
INCOMPATIBILITY.
kuncar@50878
  1719
kuncar@50878
  1720
* Lifting:
kuncar@50878
  1721
  - generation of an abstraction function equation in lift_definition
kuncar@50878
  1722
  - quot_del attribute
kuncar@50878
  1723
  - renamed no_abs_code -> no_code (INCOMPATIBILITY.)
kuncar@50878
  1724
wenzelm@50646
  1725
* Simproc "finite_Collect" rewrites set comprehensions into pointfree
wenzelm@50646
  1726
expressions.
wenzelm@50646
  1727
wenzelm@50646
  1728
* Preprocessing of the code generator rewrites set comprehensions into
wenzelm@50646
  1729
pointfree expressions.
wenzelm@50646
  1730
wenzelm@50646
  1731
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
  1732
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
  1733
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
  1734
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
  1735
INCOMPATIBILITY.
haftmann@49948
  1736
wenzelm@49836
  1737
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  1738
set definition and alternative name have been discontinued.  The
wenzelm@49836
  1739
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
  1740
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
  1741
accordingly.
wenzelm@49836
  1742
wenzelm@50646
  1743
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
  1744
directly.  INCOMPATIBILITY.
wenzelm@50646
  1745
wenzelm@50646
  1746
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
  1747
List.  INCOMPATIBILITY.
haftmann@49822
  1748
haftmann@49739
  1749
* Theorem UN_o generalized to SUP_comp.  INCOMPATIBILITY.
haftmann@49739
  1750
haftmann@49738
  1751
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
  1752
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
  1753
wenzelm@50646
  1754
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
  1755
wenzelm@50646
  1756
* Theory "Transitive_Closure": renamed lemmas
wenzelm@50646
  1757
wenzelm@50646
  1758
  reflcl_tranclp -> reflclp_tranclp
wenzelm@50646
  1759
  rtranclp_reflcl -> rtranclp_reflclp
wenzelm@50646
  1760
wenzelm@50646
  1761
INCOMPATIBILITY.
wenzelm@50646
  1762
wenzelm@50646
  1763
* Theory "Rings": renamed lemmas (in class semiring)
wenzelm@50646
  1764
wenzelm@50646
  1765
  left_distrib ~> distrib_right
wenzelm@50646
  1766
  right_distrib ~> distrib_left
wenzelm@50646
  1767
wenzelm@50646
  1768
INCOMPATIBILITY.
wenzelm@50646
  1769
wenzelm@50646
  1770
* Generalized the definition of limits:
wenzelm@50646
  1771
wenzelm@50646
  1772
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  1773
    expresses that when the input values x converge to F then the
wenzelm@50646
  1774
    output f x converges to G.
wenzelm@50646
  1775
wenzelm@50646
  1776
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  1777
    infinity (at_bot).
wenzelm@50646
  1778
wenzelm@50646
  1779
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  1780
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  1781
wenzelm@50646
  1782
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
  1783
    at_top".
wenzelm@50646
  1784
wenzelm@50646
  1785
INCOMPATIBILITY.
wenzelm@50646
  1786
wenzelm@50646
  1787
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
  1788
lattice type classes.
wenzelm@50646
  1789
wenzelm@50646
  1790
* Theory "Library/Multiset": renamed
wenzelm@50646
  1791
wenzelm@50646
  1792
    constant fold_mset ~> Multiset.fold
wenzelm@50646
  1793
    fact fold_mset_commute ~> fold_mset_comm
wenzelm@50646
  1794
wenzelm@50646
  1795
INCOMPATIBILITY.
wenzelm@50646
  1796
wenzelm@50646
  1797
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  1798
changes as follows.
wenzelm@50646
  1799
wenzelm@50646
  1800
  - Renamed constants (and related lemmas)
Christian@49145
  1801
Christian@49145
  1802
      prefix ~> prefixeq
Christian@49145
  1803
      strict_prefix ~> prefix
Christian@49145
  1804
wenzelm@50646
  1805
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  1806
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  1807
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  1808
    Renamed lemmas accordingly.
wenzelm@50646
  1809
wenzelm@50646
  1810
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  1811
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  1812
    "list_hembeq (op =)".
wenzelm@50646
  1813
wenzelm@50646
  1814
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  1815
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  1816
    interpretations). The type class instances are now in theory
wenzelm@50646
  1817
    Library/Prefix_Order.
wenzelm@50646
  1818
wenzelm@50646
  1819
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
  1820
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516
  1821
Christian@50516
  1822
      le_list_append_le_same_iff ~> Sublist.sublisteq_append_le_same_iff
Christian@50516
  1823
      le_list_append_mono ~> Sublist.list_hembeq_append_mono
Christian@50516
  1824
      le_list_below_empty ~> Sublist.list_hembeq_Nil, Sublist.list_hembeq_Nil2
Christian@50516
  1825
      le_list_Cons_EX ~> Sublist.list_hembeq_ConsD
Christian@50516
  1826
      le_list_drop_Cons2 ~> Sublist.sublisteq_Cons2'
Christian@50516
  1827
      le_list_drop_Cons_neq ~> Sublist.sublisteq_Cons2_neq
Christian@50516
  1828
      le_list_drop_Cons ~> Sublist.sublisteq_Cons'
Christian@50516
  1829
      le_list_drop_many ~> Sublist.sublisteq_drop_many
Christian@50516
  1830
      le_list_filter_left ~> Sublist.sublisteq_filter_left

*** Document preparation ***
wenzelm@48206
  1948
wenzelm@50646
  1949
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  1950
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  1951
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  1952
wenzelm@50646
  1953
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  1954
instead of slightly exotic babel/greek.
wenzelm@48206
  1955
wenzelm@48616
  1956
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  1957
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  1958
document/root.tex.
wenzelm@48616
  1959
wenzelm@48657
  1960

*** ML ***
wenzelm@48992
  1965
wenzelm@50646
  1966
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  1967
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  1968
hardware and Poly/ML runtime system.
wenzelm@50646
  1969
wenzelm@49869
  1970
* Type Seq.results and related operations support embedded error
wenzelm@49869
  1971
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  1972
informative errors in the absence of any usable results.
wenzelm@49869
  1973
wenzelm@48992
  1974
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  1975
formal device to inline positions into message text, but not
wenzelm@48992
  1976
necessarily printing visible text.

*** System ***
wenzelm@48206
  1980
wenzelm@48585
  1981
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  1982
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  1983
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  1984
session root directories for use with "isabelle build", similar to
wenzelm@51056
  1985
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  1986
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  1987
mkdir / make are rendered obsolete.
wenzelm@48736
  1988
wenzelm@51056
  1989
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  1990
regular isabelle build tool.  For example:
wenzelm@51056
  1991
wenzelm@51056
  1992
  isabelle build -s -b HOL
wenzelm@51056
  1993
wenzelm@48736
  1994
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  1995
wenzelm@48722
  1996
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  1997
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  1998
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  1999
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  2000
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  2001
wenzelm@48693
  2002
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  2003
required for "isabelle build", for example.
wenzelm@48693
  2004
wenzelm@50646
  2005
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  2006
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  2007
wenzelm@50646
  2008
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  2009
INCOMPATIBILITY.
wenzelm@50646
  2010
wenzelm@48844
  2011
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  2012
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  2013
version of Isabelle.
wenzelm@48844
  2014
wenzelm@50646
  2015
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
  2016
platform family: "linux", "macos", "windows".
wenzelm@50646
  2017
wenzelm@50646
  2018
* The ML system is configured as regular component, and no longer
wenzelm@50646
  2019
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  2020
for home-made settings.
wenzelm@50132
  2021
wenzelm@50701
  2022
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  2023
wenzelm@48206
  2024
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  2025
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  2026
configuration.
wenzelm@48206
  2027
wenzelm@48574
  2028
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  2029
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  2030
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  2031
settings manually, or use a Proof General version that has been
wenzelm@48574
  2032
bundled as Isabelle component.

wenzelm@45593
  2039
*** General ***
wenzelm@45593
  2040
wenzelm@45614
  2041
* Prover IDE (PIDE) improvements:
wenzelm@45614
  2042
wenzelm@47585
  2043
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  2044
    command-line needs to be typed into the source buffer)
wenzelm@45614
  2045
  - markup for bound variables
wenzelm@47806
  2046
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  2047
  - support for user-defined Isar commands within the running session
wenzelm@47158
  2048
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  2049
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  2050
wenzelm@47806
  2051
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  2052
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  2053
commands to be used in the same theory where defined.
wenzelm@46485
  2054
wenzelm@47482
  2055
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  2056
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  2057
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  2058
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  2059
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  2060
wenzelm@47482
  2061
  context
wenzelm@47482
  2062
    fixes x y z :: 'a
wenzelm@47482
  2063
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  2064
  begin
wenzelm@47482
  2065
wenzelm@47482
  2066
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  2067
wenzelm@47482
  2068
  end
wenzelm@47482
  2069
wenzelm@47482
  2070
  thm my_trans
wenzelm@47482
  2071
wenzelm@47482
  2072
The most basic application is to factor-out context elements of
wenzelm@47482
  2073
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  2074
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  2075
wenzelm@47482
  2076
Any other local theory specification element works within the "context
wenzelm@47482
  2077
... begin ... end" block as well.
wenzelm@47482
  2078
wenzelm@47484
  2079
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  2080
given name in the context.  These may be later included in other
wenzelm@47484
  2081
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  2082
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  2083
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  2084
wenzelm@47829
  2085
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  2086
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  2087
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  2088
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  2089
indices of schematic variables.
wenzelm@47829
  2090
wenzelm@47829
  2091
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  2092
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  2093
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  2094
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  2095
etc. was exploited.
wenzelm@47829
  2096
wenzelm@47829
  2097
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  2098
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  2099
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  2100
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  2101
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  2102
of the material of that old tutorial.
wenzelm@47829
  2103
wenzelm@47829
  2104
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  2105
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  2106
manual.

*** Pure ***
wenzelm@47829
  2110
wenzelm@46976
  2111
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  2112
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  2113
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  2114
wenzelm@47855
  2115
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  2116
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  2117
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  2118
undocumented feature.)
wenzelm@47855
  2119
wenzelm@47856
  2120
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  2121
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  2122
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  2123
wenzelm@47856
  2124
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  2125
wenzelm@47856
  2126
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  2127
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  2128
wenzelm@47856
  2129
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  2130
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  2131
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  2132
order to accommodate newly introduced premises.)
wenzelm@47856
  2133
wenzelm@47806
  2134
* Renamed some inner syntax categories:
wenzelm@47806
  2135
wenzelm@47806
  2136
    num ~> num_token
wenzelm@47806
  2137
    xnum ~> xnum_token
wenzelm@47806
  2138
    xstr ~> str_token
wenzelm@47806
  2139
wenzelm@47806
  2140
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  2141
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  2142
position information via constraints).
wenzelm@47806
  2143
wenzelm@47829
  2144
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  2145
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  2146
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  2147
wenzelm@47856
  2148
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  2149
in parse trees are always annotated by position constraints.
wenzelm@45134
  2150
wenzelm@47464
  2151
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  2152
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  2153
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  2154
wenzelm@47464
  2155
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  2156
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  2157
wenzelm@47464
  2158
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  2159
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  2160
haftmann@46028
  2161
  definition [code_abbrev]: "f = t"
haftmann@46028
  2162
haftmann@46028
  2163
INCOMPATIBILITY.
wenzelm@45383
  2164
wenzelm@47856
  2165
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  2166
instead.  INCOMPATIBILITY.
wenzelm@47856
  2167
wenzelm@47856
  2168
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  2169
collection of foundational premises in the context (already marked as
wenzelm@47856
  2170
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  2176
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  2177
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  2178
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  2179
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  2180
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  2181
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  2182
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  2183
possible.
wenzelm@47855
  2184
wenzelm@47855
  2185
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  2186
planning step is necessary to determine what should become a predicate
wenzelm@47464
  2187
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  2188
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  2189
wenzelm@47855
  2190
* Code generation by default implements sets as container type rather
wenzelm@47855
  2191
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  2192
wenzelm@47855
  2193
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
  2194
wenzelm@47464
  2195
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  2196
represents strictly positive binary numerals, along with functions
wenzelm@47464
  2197
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  2198
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  2199
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  2200
user theories may require adaptations as follows:
huffman@47108
  2201
huffman@47108
  2202
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  2203
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  2204
huffman@47108
  2205
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  2206
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  2207
    after classes one and semigroup_add have been instantiated.
huffman@47108
  2208
huffman@47108
  2209
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  2210
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  2211
huffman@47108
  2212
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  2213
    automatically support numerals now, so more simp rules and
huffman@47108
  2214
    simprocs may now apply within the proof.
huffman@47108
  2215
huffman@47108
  2216
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
  2217
    Redefine using other integer operations.
huffman@47108
  2218
wenzelm@47855
  2219
* Transfer: New package intended to generalize the existing
wenzelm@47855
  2220
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  2221
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  2222
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  2223
corresponding parts of the Quotient package.)
wenzelm@47809
  2224
wenzelm@47809
  2225
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  2226
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  2227
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  2228
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  2229
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  2230
wenzelm@47809
  2231
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  2232
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  2233
wenzelm@47809
  2234
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  2235
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  2236
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  2237
    Goals are generalized over all free variables by default; this is
huffman@47851
  2238
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  2239
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  2240
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  2241
    is logically stronger (rather than equivalent).
wenzelm@47809
  2242
wenzelm@47809
  2243
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  2244
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  2245
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  2246
    non-polymorphic constants on the fly.
wenzelm@47809
  2247
wenzelm@47809
  2248
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  2249
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  2250
    constants that already have transfer rules. It should be applied
wenzelm@47809
  2251
    after unfolding the constant definitions.

wenzelm@47809
  2254
    from type nat to type int.
wenzelm@47809
  2255
huffman@47851
  2256
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  2257
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  2258
wenzelm@47809
  2259
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  2260
    terms of a corresponding operation on a representation
wenzelm@47809
  2261
    type.  Example syntax:
wenzelm@47809
  2262
wenzelm@47809
  2263
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  2264
      is List.insert
wenzelm@47809
  2265
wenzelm@47809
  2266
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  2267
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  2268
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  2269
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  2270
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  2271
    by the package.
wenzelm@47809
  2272
wenzelm@47809
  2273
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  2274
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  2275
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  2276
    code generation for each constant.
wenzelm@47809
  2277
wenzelm@47809
  2278
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  2279
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  2280
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  2281
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  2282
    lift_definition command to work with the type.
wenzelm@47809
  2283
wenzelm@47809
  2284
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  2285
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  2286
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  2287
wenzelm@47809
  2288
* Quotient package:
wenzelm@47809
  2289
wenzelm@47809
  2290
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  2291
    rep and abs functions, similar to typedef.
wenzelm@47809
  2292
wenzelm@47809
  2293
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  2294
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  2295
wenzelm@47809
  2296
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  2297
    respectfulness property at the point where the constant is
wenzelm@47809
  2298
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  2299
wenzelm@47809
  2300
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  2301
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  2302
wenzelm@47809
  2303
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  2304
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  2305
wenzelm@47809
  2306
* Quickcheck:
wenzelm@47809
  2307
wenzelm@47809
  2308
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  2309
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  2310
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  2311
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  2312
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  2313
wenzelm@47809
  2314
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  2315
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  2316
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  2317
wenzelm@47809
  2318
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  2319
    continues searching for genuine ones.
wenzelm@47809
  2320
wenzelm@47809
  2321
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  2322
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  2323
    show genuine counterexamples.
wenzelm@47809
  2324
wenzelm@47809
  2325
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  2326
    value generators for a given type and operations.
wenzelm@47809
  2327
wenzelm@47809
  2328
    It generates values by using the operations as if they were
wenzelm@47809
  2329
    constructors of that type.
wenzelm@47809
  2330
wenzelm@47809
  2331
  - Support for multisets.
wenzelm@47809
  2332
wenzelm@47809
  2333
  - Added "use_subtype" options.
wenzelm@47809
  2334
wenzelm@47809
  2335
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  2336
    conjectures in a locale context.
wenzelm@47809
  2337
wenzelm@47855
  2338
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  2339
and affecting 'rat' and 'real'.
wenzelm@47809
  2340
wenzelm@47809
  2341
* Sledgehammer:
wenzelm@47809
  2342
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  2343
    paper "More SPASS with Isabelle".
wenzelm@47809
  2344
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  2345
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  2346
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  2347
  - Sped up the minimizer.
wenzelm@47809
  2348
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  2349
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  2350
  - Renamed "sound" option to "strict".
wenzelm@47809
  2351
wenzelm@47855
  2352
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  2353
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  2354
wenzelm@47855
  2355
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  2356
wenzelm@47855
  2357
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  2358
wenzelm@47856
  2359
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  2360
case distinctions at the same time.  E.g.
wenzelm@47856
  2361
wenzelm@47856
  2362
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  2363
wenzelm@47856
  2364
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  2365
a list and a nat.
wenzelm@47856
  2366
wenzelm@47809
  2367
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  2368
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  2369
wenzelm@47702
  2370
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  2371
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  2372
default.
wenzelm@47702
  2373
wenzelm@47856
  2374
