New in this Isabelle version
wenzelm@50994
     5
----------------------------
wenzelm@50994
     6
wenzelm@51293
     7
*** General ***
wenzelm@51293
     8
wenzelm@53016
     9
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
    10
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
    11
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
    12
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
    13
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
    14
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
    15
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
    16
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
    17
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
    18
syntax.
wenzelm@53016
    19
wenzelm@53021
    20
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
    21
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
    22
wenzelm@52487
    23
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
    24
"isabelle options"), configuration option within the context (see also
wenzelm@52487
    25
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
    26
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
    27
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
    28
wenzelm@52060
    29
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
    30
INCOMPATIBILITY.
wenzelm@52060
    31
wenzelm@51417
    32
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@51417
    33
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@51417
    34
tree-like organization via implicit sub-session relation, with its
wenzelm@51417
    35
tendency towards erratic fluctuation of URLs, has been discontinued.
wenzelm@51417
    36
The default chapter is "Unsorted".  Potential INCOMPATIBILITY for HTML
wenzelm@51417
    37
presentation of theories.
wenzelm@51417
    38
wenzelm@51293
    39
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@51293
    40
commands like 'ML_file' work without separate declaration of file
wenzelm@51293
    41
dependencies.  Minor INCOMPATIBILITY.
wenzelm@51293
    42
wenzelm@51295
    43
* Discontinued redundant 'use' command, which was superseded by
wenzelm@51295
    44
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@51295
    45
wenzelm@52415
    46
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@52415
    47
eliminated old "ref" manual.
wenzelm@52415
    48
wenzelm@52430
    49
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
    50
implicit change of some global references) is retained for now as
wenzelm@52430
    51
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
    52
wenzelm@52549
    53
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
    54
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
    55
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
    56
wenzelm@51293
    57
wenzelm@51533
    58
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
    59
wenzelm@52818
    60
* Improved "Theories" panel: Continuous checking of proof document
wenzelm@52818
    61
(visible and required parts) may be controlled explicitly, using check
wenzelm@52818
    62
box or shortcut "C+e ENTER".  Individual theory nodes may be marked
wenzelm@52818
    63
explicitly as required and checked in full, using check box or
wenzelm@52818
    64
shortcut "C+e SPACE".
wenzelm@52779
    65
wenzelm@52646
    66
* Strictly monotonic document update, without premature cancelation of
wenzelm@52646
    67
running transactions that are still needed: avoid reset/restart of
wenzelm@52646
    68
such command executions while editing.
wenzelm@52646
    69
wenzelm@52646
    70
* Support for asynchronous print functions, as overlay to existing
wenzelm@52646
    71
document content.
wenzelm@52646
    72
wenzelm@52646
    73
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@52646
    74
toplevel theorem statements.
wenzelm@52646
    75
wenzelm@52949
    76
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
    77
(GUI front-end to 'find_theorems' command).
wenzelm@52949
    78
wenzelm@52445
    79
* Dockable window "Documentation" provides access to Isabelle
wenzelm@52445
    80
documentation.
wenzelm@52445
    81
wenzelm@53050
    82
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
    83
sledgehammer runs over existing document sources, independently of
wenzelm@53050
    84
normal editing and checking process.
wenzelm@53050
    85
wenzelm@51533
    86
* Dockable window "Timing" provides an overview of relevant command
wenzelm@51533
    87
timing information.
wenzelm@51533
    88
wenzelm@53161
    89
* Action isabelle.reset-font-size resets main text area font size
wenzelm@53161
    90
according to Isabelle/Scala plugin option "jedit_font_reset_size"
wenzelm@53161
    91
(cf. keyboard shortcut C+0).
wenzelm@53161
    92
wenzelm@53271
    93
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53271
    94
/ Global Options / Appearance".
wenzelm@53271
    95
wenzelm@53326
    96
* Improved completion mechanism, which is now managed by the
wenzelm@53326
    97
Isabelle/jEdit plugin instead of SideKick.
wenzelm@53326
    98
wenzelm@53326
    99
  - Various Isabelle plugin options to control popup behaviour and
wenzelm@53326
   100
    immediate insertion into buffer.
wenzelm@53326
   101
wenzelm@53326
   102
  - Light-weight popup, which avoids explicit window (more reactive
wenzelm@53342
   103
    and more robust).  Interpreted key events include TAB, ESCAPE, UP,
wenzelm@53398
   104
    DOWN, PAGE_UP, PAGE_DOWN.  All other key events are passed to
wenzelm@53342
   105
    the jEdit text area.
wenzelm@53326
   106
wenzelm@53326
   107
  - Explicit completion via standard jEdit shortcut C+b, which has
wenzelm@53326
   108
    been remapped to action "isabelle.complete" (fall-back on regular
wenzelm@53326
   109
    "complete-word" for non-Isabelle buffers).
wenzelm@53326
   110
wenzelm@53326
   111
  - Implicit completion via keyboard input on text area, with popup or
wenzelm@53326
   112
    immediate insertion into buffer.
wenzelm@53326
   113
wenzelm@53326
   114
  - Implicit completion of plain words requires at least 3 characters
wenzelm@53326
   115
    (was 2 before).
wenzelm@53326
   116
wenzelm@53326
   117
  - Immediate completion ignores plain words; it requires > 1
wenzelm@53326
   118
    characters of symbol abbreviation to complete, otherwise fall-back
wenzelm@53326
   119
    on completion popup.
wenzelm@53326
   120
wenzelm@53326
   121
  - Isabelle Symbols are only completed in backslashed forms,
wenzelm@53326
   122
    e.g. \forall or \<forall> that both produce the Isabelle symbol
wenzelm@53326
   123
    \<forall> in its Unicode rendering.
wenzelm@53326
   124
wenzelm@53326
   125
  - Refined table of Isabelle symbol abbreviations (see
wenzelm@53326
   126
    $ISABELLE_HOME/etc/symbols).
wenzelm@53326
   127
wenzelm@51533
   128
wenzelm@51313
   129
*** Pure ***
wenzelm@51313
   130
wenzelm@52788
   131
* Type theory is now immutable, without any special treatment of
wenzelm@52788
   132
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@52788
   133
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@52788
   134
Theory.checkpoint, and the auxiliary type theory_ref.  Minor
wenzelm@52788
   135
INCOMPATIBILITY.
wenzelm@52788
   136
wenzelm@52488
   137
* System option "proofs" has been discontinued.  Instead the global
wenzelm@52488
   138
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@52488
   139
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@52488
   140
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@52488
   141
wenzelm@52143
   142
* Syntax translation functions (print_translation etc.) always depend
wenzelm@52143
   143
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@52143
   144
now the default.  Minor INCOMPATIBILITY.
wenzelm@52143
   145
haftmann@51747
   146
* Target-sensitive commands 'interpretation' and 'sublocale'.
haftmann@51747
   147
Particulary, 'interpretation' now allows for non-persistent
wenzelm@53160
   148
interpretation within "context ... begin ... end" blocks.  See
wenzelm@53160
   149
"isar-ref" manual for details.
haftmann@51747
   150
ballarin@51565
   151
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
   152
wenzelm@51313
   153
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
   154
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
   155
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
   156
wenzelm@51316
   157
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
   158
INCOMPATIBILITY.
wenzelm@51316
   159
wenzelm@52463
   160
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
   161
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
   162
situations.
wenzelm@52463
   163
wenzelm@51313
   164
hoelzl@51002
   165
*** HOL ***
hoelzl@51002
   166
blanchet@53307
   167
* Improved support for ad hoc overloading of constants (see also
wenzelm@52896
   168
isar-ref manual and ~~/src/HOL/ex/Adhoc_Overloading_Examples.thy).
wenzelm@52896
   169
wenzelm@53160
   170
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@53160
   171
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@53160
   172
to distinguish both when desired.
haftmann@52637
   173
haftmann@52435
   174
* Code generator:
wenzelm@53160
   175
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
   176
    'code_instance'.
wenzelm@53160
   177
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
   178
    generated code, subsuming 'code_modulename'.
wenzelm@53160
   179
  See the isar-ref manual for syntax diagrams, and the HOL theories
wenzelm@53160
   180
  for examples.
haftmann@52435
   181
blanchet@53307
   182
* HOL/BNF:
blanchet@53307
   183
  - Various improvements to BNF-based (co)datatype package, including a
blanchet@53309
   184
    "primrec_new" command, a "datatype_new_compat" command, and
blanchet@53307
   185
    documentation. See "datatypes.pdf" for details.
blanchet@53307
   186
  - Renamed keywords:
blanchet@53307
   187
    data ~> datatype_new
blanchet@53307
   188
    codata ~> codatatype
blanchet@53307
   189
    bnf_def ~> bnf
blanchet@53307
   190
  - Renamed many generated theorems, including
blanchet@53307
   191
    map_comp' ~> map_comp
blanchet@53307
   192
    map_id' ~> map_id
blanchet@53307
   193
    set_map' ~> set_map
blanchet@53307
   194
IMCOMPATIBILITY.
blanchet@53307
   195
haftmann@52380
   196
* Library/Polynomial.thy:
wenzelm@53160
   197
  - Use lifting for primitive definitions.
wenzelm@53160
   198
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@53160
   199
    generated code.
wenzelm@53160
   200
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@53160
   201
  - Prefer pre-existing gcd operation for gcd.
wenzelm@53160
   202
  - Fact renames:
haftmann@52380
   203
    poly_eq_iff ~> poly_eq_poly_eq_iff
haftmann@52380
   204
    poly_ext ~> poly_eqI
haftmann@52380
   205
    expand_poly_eq ~> poly_eq_iff
blanchet@53307
   206
IMCOMPATIBILITY.
haftmann@52380
   207
haftmann@52286
   208
* Reification and reflection:
wenzelm@53160
   209
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
   210
    "Reification".
wenzelm@53160
   211
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
   212
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
   213
INCOMPATIBILITY.
haftmann@52286
   214
haftmann@52141
   215
* Weaker precendence of syntax for big intersection and union on sets,
haftmann@52141
   216
in accordance with corresponding lattice operations.  INCOMPATIBILITY.
haftmann@52141
   217
wenzelm@53160
   218
* Nested case expressions are now translated in a separate check phase
wenzelm@53160
   219
rather than during parsing. The data for case combinators is separated
wenzelm@53160
   220
from the datatype package. The declaration attribute
wenzelm@53160
   221
"case_translation" can be used to register new case combinators:
traytel@51682
   222
traytel@51682
   223
  declare [[case_translation case_combinator constructor1 ... constructorN]]
traytel@51682
   224
wenzelm@51596
   225
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@51596
   226
haftmann@51489
   227
* Revised devices for recursive definitions over finite sets:
haftmann@51489
   228
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
   229
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
   230
    This is now identity on infinite sets.
wenzelm@52745
   231
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
   232
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
   233
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
   234
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
   235
    See theory Big_Operators for canonical examples.
haftmann@51489
   236
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
   237
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
   238
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
   239
    those foundational constants as substitutes, but it is
haftmann@51489
   240
    preferable to interpret the above locales accordingly. 
haftmann@51489
   241
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
   242
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
   243
  - Fact renames:
haftmann@51489
   244
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
   245
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
   246
INCOMPATIBILITY.
haftmann@51489
   247
haftmann@51487
   248
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
   249
wenzelm@53526
   250
* Discontinued theory src/HOL/Library/Eval_Witness.  INCOMPATIBILITY.
haftmann@51382
   251
wenzelm@51238
   252
* Discontinued obsolete src/HOL/IsaMakefile (considered legacy since
wenzelm@51238
   253
Isabelle2013).  Use "isabelle build" to operate on Isabelle sessions.
wenzelm@51238
   254
wenzelm@53160
   255
* Numeric types mapped by default to target language numerals: natural
wenzelm@53160
   256
(replaces former code_numeral) and integer (replaces former code_int).
wenzelm@53160
   257
Conversions are available as integer_of_natural / natural_of_integer /
wenzelm@53160
   258
integer_of_nat / nat_of_integer (in HOL) and
wenzelm@53160
   259
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@53160
   260
ML).  INCOMPATIBILITY.
haftmann@51168
   261
haftmann@51168
   262
* Discontinued theories Code_Integer and Efficient_Nat by a more
haftmann@51168
   263
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@53160
   264
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@53160
   265
generation for details.  INCOMPATIBILITY.
wenzelm@53160
   266
wenzelm@53526
   267
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
   268
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
   269
class predicate assumption or sort constraint when possible.
Andreas@53362
   270

* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
   273
complete lattice but does not assume the existence of the top and
wenzelm@53160
   274
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
   275
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
   276
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
   277
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
   278
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
   279
lemmas.
wenzelm@53160
   280
wenzelm@53160
   281
* Introduce type class linear_continuum as combination of
wenzelm@53160
   282
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
   283
more than one element.  INCOMPATIBILITY.
wenzelm@53160
   284
wenzelm@53160
   285
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
   286
top and bottom elements.
hoelzl@51732
   287
hoelzl@51732

hoelzl@51775
   293
 - Introduce type class (lin)order_topology and linear_continuum_topology.
hoelzl@51775
   294
   Allows to generalize theorems about limits and order.
hoelzl@51775
   295
   Instances are reals and extended reals.
hoelzl@51732
   296
hoelzl@51732
   297
 - continuous and continuos_on from Multivariate_Analysis:
hoelzl@51732
   298
   "continuous" is the continuity of a function at a filter.
hoelzl@51732
   299
   "isCont" is now an abbrevitation: "isCont x f == continuous (at _) f".
hoelzl@51732
   300
hoelzl@51732
   301
   Generalized continuity lemmas from isCont to continuous on an arbitrary
hoelzl@51732
   302
   filter.
hoelzl@51732
   303
hoelzl@51732
   304
 - compact from Multivariate_Analysis. Use Bolzano's lemma
hoelzl@51732
   305
   to prove compactness of closed intervals on reals. Continuous functions
hoelzl@51732
   306
   attain infimum and supremum on compact sets. The inverse of a continuous
hoelzl@51732
   307
   function is continuous, when the function is continuous on a compact set.
hoelzl@51732
   308
hoelzl@51732
   309
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775

   linear_continuum_topology).
hoelzl@51732
   312
hoelzl@51732

 - first_countable_topology from Multivariate_Analysis. Is used to
hoelzl@51732
   314
   show equivalence of properties on the neighbourhood filter of x and on
hoelzl@51732
   315
   all sequences converging to x.
hoelzl@51732
   316
hoelzl@51732
   317
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved theorems
hoelzl@51732
   318
   from Library/FDERIV.thy to Deriv.thy and base the definition of DERIV on
hoelzl@51732
   319
   FDERIV. Add variants of DERIV and FDERIV which are restricted to sets,
hoelzl@51732
   320
   i.e. to represent derivatives from left or right.
hoelzl@51732
   321
hoelzl@51732
   322
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
   323
hoelzl@51732
   324
     F within X = inf F (principal X)
hoelzl@51732
   325
hoelzl@51732
   326
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
   327
   abbreviation for "at x within UNIV"
hoelzl@51732
   328
hoelzl@51732
   329
 - Introduce named theorem collections tendsto_intros, continuous_intros,
hoelzl@51732
   330
   continuous_on_intros and FDERIV_intros. Theorems in tendsto_intros (or
hoelzl@51732
   331
   FDERIV_intros) are also available as tendsto_eq_intros (or
hoelzl@51732
   332
   FDERIV_eq_intros) where the right-hand side is replaced by a congruence
hoelzl@51732
   333
   rule. This allows to apply them as intro rules and then proving
hoelzl@51732
   334
   equivalence by the simplifier.

hoelzl@51732
   338
   + Moved RealDef and RComplete into Real
hoelzl@51732
   339
hoelzl@51732
   340
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732

     topological spaces, filters, limits and continuity to it
hoelzl@51732
   342
hoelzl@51732
   343
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
   344
hoelzl@51732
   345
   + Split Lim, SEQ, Series into Topological_Spaces, Real_Vector_Spaces, and

   346
     Limits
hoelzl@51732
   347
hoelzl@51732
   348
   + Moved Ln and Log to Transcendental
hoelzl@51732
   349
hoelzl@51732
   350
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732

* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@51703
   394
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@51703

historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
   400

no longer printed by default, since it is incompatible with
wenzelm@50126
   444
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
   445
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
   446
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
   447
isabelle build --- the system ensures that future proofs of all
wenzelm@50126

accessible theorems in the theory context are finished (as before).
wenzelm@50126

wenzelm@49243
   458
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243

wenzelm@49243
   460
Tools that load their additional source files may imitate the

is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
   466
wenzelm@50110
   467
* Updated and extended "isar-ref" and "implementation" manual, reduced

   468
remaining material in old "ref" manual.
wenzelm@48120
   469
wenzelm@51050
   470
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
   471
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
   472
and "class ... context ...".
wenzelm@49841
   473
wenzelm@50772
   474
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
   475
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
   476
the target context.  This form of declaration is stable when exported
wenzelm@50772
   477
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
   478
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
   479
in HOL/inductive and HOL/function.

* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
   491
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
   492
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
   493
surface, while the prover is still crunching on internal
wenzelm@49968
   494
justifications.  Unfinished / cancelled proofs are restarted as

   495
required to complete full proof checking eventually.
wenzelm@49968
   496
wenzelm@49968
   497
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
   498
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
   499
tooltips leads to some window that supports the same recursively,
wenzelm@49968
   500
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
   501
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
   502
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
   503
wenzelm@50717

wenzelm@50717
   506
browser on demand.
wenzelm@50717
   507
wenzelm@49968
   508
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
   509
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
   510
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
   511
that frequently occur in user interaction.
wenzelm@49968
   512
wenzelm@49968
   513
* More efficient painting and improved reactivity when editing large
wenzelm@49968
   514
files.  More scalable management of formal document content.
wenzelm@49968
   515
wenzelm@50505
   516
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
   517
certain number of messages per command transaction, with some user
wenzelm@50505
   518
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
   519
potentially infinite message streams.
wenzelm@49968
   520
wenzelm@49968
   521
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
   522
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
   523
options, including tuning parameters for editor reactivity and color
wenzelm@49968
   524
schemes.
wenzelm@49968
   525
wenzelm@50184

   527
symbols.
wenzelm@50184
   528
wenzelm@51082
   529
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
   530
continuous display of the chart slows down the system.
wenzelm@50701
   531
wenzelm@50183

wenzelm@50183
   533
bold, reset of style -- operating on single symbols or text
wenzelm@50198
   534
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
   535
wenzelm@50198
   536
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
   537
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
   538
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
   539
need to be adapted to local keyboard layouts.
wenzelm@50183
   540
wenzelm@50730
   541
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
   542
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See

* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
   565
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
   566
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
   567
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
   568
with some care where this is really required.

  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
   587
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
   588
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646

wenzelm@50646
   615
arithmetic, datatypes/records) with potential proof reconstruction

* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
   620
set definition and alternative name have been discontinued.  The
wenzelm@49836
   621
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836

subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
   635
wenzelm@50646

   652
* Generalized the definition of limits:
wenzelm@50646
   653
wenzelm@50646
   654
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
   655
    expresses that when the input values x converge to F then the
wenzelm@50646
   656
    output f x converges to G.
wenzelm@50646
   657
wenzelm@50646
   658
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
   659
    infinity (at_bot).
wenzelm@50646
   660
wenzelm@50646
   661
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
   662
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
   663
wenzelm@50646
   664
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646

   685
      strict_prefix ~> prefix
Christian@49145
   686
wenzelm@50646
   687
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
   688
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
   689
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
   690
    Renamed lemmas accordingly.
wenzelm@50646
   691
wenzelm@50646
   692
  - Added constant "list_hembeq" for homeomorphic embedding on

   693
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
   694
    "list_hembeq (op =)".
wenzelm@50646

   696
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
   697
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
   698
    interpretations). The type class instances are now in theory
wenzelm@50646
   699
    Library/Prefix_Order.
wenzelm@50646
   700
wenzelm@50646

wenzelm@50646
   831
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
   832
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
   833
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
   834
wenzelm@50646
   835
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
   836
instead of slightly exotic babel/greek.
wenzelm@48206
   837
wenzelm@48616
   838
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
   839
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
   840
document/root.tex.
wenzelm@48616
   841
wenzelm@48657
   842
* Simplified custom document/build script, instead of old-style

wenzelm@48992
   847
wenzelm@50646
   848
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
   849
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
   850
hardware and Poly/ML runtime system.
wenzelm@50646
   851
wenzelm@49869
   852
* Type Seq.results and related operations support embedded error
wenzelm@49869
   853
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
   854
informative errors in the absence of any usable results.
wenzelm@49869
   855
wenzelm@48992
   856
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
   857
formal device to inline positions into message text, but not
wenzelm@48992
   858
necessarily printing visible text.

*** System ***
wenzelm@48206
   862
wenzelm@48585
   863
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
   864
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
   865
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
   866
session root directories for use with "isabelle build", similar to
wenzelm@51056
   867
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
   868
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
   869
mkdir / make are rendered obsolete.
wenzelm@48736
   870
wenzelm@51056
   871
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
   872
regular isabelle build tool.  For example:
wenzelm@51056
   873
wenzelm@51056
   874
  isabelle build -s -b HOL
wenzelm@51056
   875
wenzelm@48736
   876
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
   877
wenzelm@48722
   878
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
   879
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
   880
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
   881
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
   882
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
   883
wenzelm@48693
   884
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
   885
required for "isabelle build", for example.
wenzelm@48693
   886
wenzelm@50646
   887
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
   888
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
   889
wenzelm@50646
   890
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
   891
INCOMPATIBILITY.
wenzelm@50646
   892
wenzelm@48844
   893
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
   894
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
   895
version of Isabelle.
wenzelm@48844
   896
wenzelm@50646
   897
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
   898
platform family: "linux", "macos", "windows".
wenzelm@50646
   899
wenzelm@50646
   900
* The ML system is configured as regular component, and no longer
wenzelm@50646
   901
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
   902
for home-made settings.
wenzelm@50132
   903
wenzelm@50701
   904
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
   905
wenzelm@48206
   906
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
   907
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
   908
configuration.
wenzelm@48206
   909
wenzelm@48574
   910
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
   911
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
   912
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
   913
settings manually, or use a Proof General version that has been
wenzelm@48574
   914
bundled as Isabelle component.

wenzelm@45593
   921
*** General ***
wenzelm@45593
   922
wenzelm@45614
   923
* Prover IDE (PIDE) improvements:
wenzelm@45614
   924
wenzelm@47585
   925
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
   926
    command-line needs to be typed into the source buffer)
wenzelm@45614
   927
  - markup for bound variables
wenzelm@47806
   928
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
   929
  - support for user-defined Isar commands within the running session
wenzelm@47158
   930
  - improved support for Unicode outside original 16bit range
wenzelm@47158
   931
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
   932
wenzelm@47806
   933
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
   934
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
   935
commands to be used in the same theory where defined.
wenzelm@46485
   936
wenzelm@47482
   937
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
   938
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
   939
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
   940
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
   941
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
   942
wenzelm@47482
   943
  context
wenzelm@47482
   944
    fixes x y z :: 'a
wenzelm@47482
   945
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
   946
  begin
wenzelm@47482
   947
wenzelm@47482
   948
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
   949
wenzelm@47482
   950
  end
wenzelm@47482
   951
wenzelm@47482
   952
  thm my_trans
wenzelm@47482
   953
wenzelm@47482
   954
The most basic application is to factor-out context elements of
wenzelm@47482
   955
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
   956
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
   957
wenzelm@47482
   958
Any other local theory specification element works within the "context
wenzelm@47482
   959
... begin ... end" block as well.
wenzelm@47482
   960
wenzelm@47484
   961
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
   962
given name in the context.  These may be later included in other
wenzelm@47484
   963
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
   964
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
   965
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
   966
wenzelm@47829
   967
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
   968
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
   969
old-style "standard" after instantiation or composition of facts
wenzelm@47829
   970
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
   971
indices of schematic variables.
wenzelm@47829
   972
wenzelm@47829
   973
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
   974
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
   975
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
   976
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
   977
etc. was exploited.
wenzelm@47829
   978
wenzelm@47829
   979
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
   980
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
   981
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
   982
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
   983
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
   984
of the material of that old tutorial.
wenzelm@47829
   985
wenzelm@47829
   986
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
   987
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
   988
manual.
wenzelm@47829

wenzelm@47829
   991
*** Pure ***
wenzelm@47829
   992
wenzelm@46976
   993
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
   994
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
   995
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
   996
wenzelm@47855
   997
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
   998
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
   999
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  1000
undocumented feature.)
wenzelm@47855
  1001
wenzelm@47856
  1002
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  1003
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  1004
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  1005
wenzelm@47856
  1006
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  1007
wenzelm@47856
  1008
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  1009
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  1010
wenzelm@47856
  1011
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  1012
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  1013
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  1014
order to accommodate newly introduced premises.)
wenzelm@47856
  1015
wenzelm@47806
  1016
* Renamed some inner syntax categories:
wenzelm@47806
  1017
wenzelm@47806
  1018
    num ~> num_token
wenzelm@47806
  1019
    xnum ~> xnum_token
wenzelm@47806
  1020
    xstr ~> str_token
wenzelm@47806
  1021
wenzelm@47806
  1022
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  1023
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  1024
position information via constraints).
wenzelm@47806
  1025
wenzelm@47829
  1026
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  1027
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  1028
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  1029
wenzelm@47856
  1030
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  1031
in parse trees are always annotated by position constraints.
wenzelm@45134
  1032
wenzelm@47464
  1033
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  1034
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  1035
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  1036
wenzelm@47464
  1037
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  1038
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  1039
wenzelm@47464
  1040
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  1041
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  1042
haftmann@46028
  1043
  definition [code_abbrev]: "f = t"
haftmann@46028
  1044
haftmann@46028
  1045
INCOMPATIBILITY.
wenzelm@45383
  1046
wenzelm@47856
  1047
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  1048
instead.  INCOMPATIBILITY.
wenzelm@47856
  1049
wenzelm@47856
  1050
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  1051
collection of foundational premises in the context (already marked as
wenzelm@47856
  1052
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  1058
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  1059
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  1060
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  1061
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  1062
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  1063
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  1064
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  1065
possible.
wenzelm@47855
  1066
wenzelm@47855
  1067
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  1068
planning step is necessary to determine what should become a predicate
wenzelm@47464
  1069
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  1070
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  1071
wenzelm@47855
  1072
* Code generation by default implements sets as container type rather
wenzelm@47855
  1073
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  1074
wenzelm@47855
  1075
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
  1076
wenzelm@47464
  1077
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  1078
represents strictly positive binary numerals, along with functions
wenzelm@47464
  1079
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  1080
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  1081
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  1082
user theories may require adaptations as follows:
huffman@47108
  1083
huffman@47108
  1084
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  1085
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  1086
huffman@47108
  1087
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  1088
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  1089
    after classes one and semigroup_add have been instantiated.
huffman@47108
  1090
huffman@47108
  1091
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  1092
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  1093
huffman@47108
  1094
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  1095
    automatically support numerals now, so more simp rules and
huffman@47108
  1096
    simprocs may now apply within the proof.
huffman@47108
  1097
huffman@47108

  1101
* Transfer: New package intended to generalize the existing
wenzelm@47855
  1102
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  1103
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  1104
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  1105
corresponding parts of the Quotient package.)
wenzelm@47809
  1106
wenzelm@47809
  1107
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  1108
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  1109
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  1110
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  1111
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  1112
wenzelm@47809
  1113
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  1114
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  1115
wenzelm@47809
  1116
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  1117
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  1118
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  1119
    Goals are generalized over all free variables by default; this is
huffman@47851
  1120
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  1121
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  1122
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  1123
    is logically stronger (rather than equivalent).
wenzelm@47809
  1124
wenzelm@47809
  1125
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  1126
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  1127
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  1128
    non-polymorphic constants on the fly.
wenzelm@47809
  1129
wenzelm@47809
  1130
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  1131
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  1132
    constants that already have transfer rules. It should be applied
wenzelm@47809
  1133
    after unfolding the constant definitions.
wenzelm@47809
  1134
wenzelm@47809
  1135
  - HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer
wenzelm@47809
  1136
    from type nat to type int.
wenzelm@47809
  1137
huffman@47851
  1138
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  1139
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  1140
wenzelm@47809
  1141
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  1142
    terms of a corresponding operation on a representation
wenzelm@47809
  1143
    type.  Example syntax:
wenzelm@47809
  1144
wenzelm@47809
  1145
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  1146
      is List.insert
wenzelm@47809
  1147
wenzelm@47809
  1148
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  1149
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  1150
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  1151
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  1152
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  1153
    by the package.
wenzelm@47809
  1154
wenzelm@47809
  1155
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  1156
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  1157
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  1158
    code generation for each constant.
wenzelm@47809
  1159
wenzelm@47809
  1160
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  1161
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  1162
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  1163
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  1164
    lift_definition command to work with the type.
wenzelm@47809
  1165
wenzelm@47809
  1166
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  1167
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  1168
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  1169
wenzelm@47809
  1170
* Quotient package:
wenzelm@47809
  1171
wenzelm@47809
  1172
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  1173
    rep and abs functions, similar to typedef.
wenzelm@47809
  1174
wenzelm@47809
  1175
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  1176
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  1177
wenzelm@47809
  1178
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  1179
    respectfulness property at the point where the constant is
wenzelm@47809
  1180
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  1181
wenzelm@47809
  1182
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  1183
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  1184
wenzelm@47809
  1185
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  1186
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  1187
wenzelm@47809
  1188
* Quickcheck:
wenzelm@47809
  1189
wenzelm@47809
  1190
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  1191
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  1192
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  1193
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  1194
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  1195
wenzelm@47809
  1196
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  1197
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  1198
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  1199
wenzelm@47809
  1200
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  1201
    continues searching for genuine ones.
wenzelm@47809
  1202
wenzelm@47809
  1203
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  1204
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  1205
    show genuine counterexamples.
wenzelm@47809
  1206
wenzelm@47809
  1207
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  1208
    value generators for a given type and operations.
wenzelm@47809
  1209
wenzelm@47809
  1210
    It generates values by using the operations as if they were
wenzelm@47809
  1211
    constructors of that type.
wenzelm@47809
  1212
wenzelm@47809
  1213
  - Support for multisets.
wenzelm@47809
  1214
wenzelm@47809
  1215
  - Added "use_subtype" options.
wenzelm@47809
  1216
wenzelm@47809
  1217
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  1218
    conjectures in a locale context.
wenzelm@47809
  1219
wenzelm@47855
  1220
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  1221
and affecting 'rat' and 'real'.
wenzelm@47809
  1222
wenzelm@47809
  1223
* Sledgehammer:
wenzelm@47809
  1224
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  1225
    paper "More SPASS with Isabelle".
wenzelm@47809
  1226
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  1227
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  1228
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  1229
  - Sped up the minimizer.
wenzelm@47809
  1230
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  1231
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  1232
  - Renamed "sound" option to "strict".
wenzelm@47809
  1233
wenzelm@47855
  1234
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  1235
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  1236
wenzelm@47855
  1237
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  1238
wenzelm@47855
  1239
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  1240
wenzelm@47856
  1241
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  1242
case distinctions at the same time.  E.g.
wenzelm@47856
  1243
wenzelm@47856
  1244
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  1245
wenzelm@47856
  1246
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  1247
a list and a nat.
wenzelm@47856
  1248
wenzelm@47809
  1249
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  1250
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  1251
wenzelm@47702
  1252
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  1253
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  1254
default.
wenzelm@47702
  1255
wenzelm@47856
  1256
* Record: code generation can be switched off manually with
wenzelm@47856
  1257
wenzelm@47856
  1258
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
  1259
wenzelm@47856
  1260
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
  1261
wenzelm@47855
  1262
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
  1263
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
  1264
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
  1265
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
  1266
one_case.
wenzelm@47855
  1267
wenzelm@47855
  1268
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
  1269
the result of the fact expression.
wenzelm@47855
  1270
haftmann@46752
  1271
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
  1272
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
  1273

Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
  1283
wenzelm@47464
  1284
See theory "Relation" for examples for making use of pred/set
wenzelm@47464
  1285
conversions by means of attributes "to_set" and "to_pred".

* Session HOL-Word: New proof method "word_bitwise" for splitting
wenzelm@47809
  1725
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  1726
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  1727
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  1728
constants.  Requires fixed-length word types, not 'a word.  Solves
wenzelm@47854
  1729
many standard word identities outright and converts more into first
wenzelm@47809
  1730
order problems amenable to blast or similar.  See also examples in

* Session HOL-Probability: Introduced the type "'a measure" to
wenzelm@47807
  1734
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807
  1735
measure_space.  The locales based on subset_class now have two
wenzelm@47856
  1736
locale-parameters the space \<Omega> and the set of measurable sets M.
wenzelm@47856
  1737
The product of probability spaces uses now the same constant as the
wenzelm@47856
  1738
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  1739
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  1740
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  1741
Measure space constructions for distributions and densities now got
wenzelm@47807
  1742
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  1743
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  1744
and point_measure is introduced.  INCOMPATIBILITY.

from a minor keyword introduced via theory header declaration.
wenzelm@46948
  1929
wenzelm@46961

Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
  1932
header declaration; it can be passed to Outer_Syntax.command etc.

wenzelm@46992
  1936
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
  1937
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
  1938
non-empty name (used for the foundation in the background theory),
wenzelm@46992
  1939
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
  1940
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
  1941
naming policy for primitive definitions more explicitly.
wenzelm@46916
  1942
wenzelm@46497
  1943
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in

  1944
conformance with similar operations in structure Term and Logic.
wenzelm@46497
  1945
wenzelm@45592
  1946
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
  1947
representation into the ML text, which is particularly useful with
wenzelm@45592
  1948
declarations like Local_Theory.note.

wenzelm@47661
  1976
directory, which coincides with HOME on POSIX systems only.  Likewise,
wenzelm@47661
  1977
the Isabelle path specification "~" now expands to $USER_HOME, instead
wenzelm@47661
  1978
of former $HOME.  A different default for USER_HOME may be set
wenzelm@47661
  1979
explicitly in shell environment, before Isabelle settings are
wenzelm@47661
  1980
evaluated.  Minor INCOMPATIBILITY: need to adapt Isabelle path where
wenzelm@47661
  1981
the generic user home was intended.
wenzelm@47661
  1982
wenzelm@47807
  1983
* ISABELLE_HOME_WINDOWS refers to ISABELLE_HOME in windows file name

  1984
notation, which is useful for the jEdit file browser, for example.
wenzelm@47807
  1985

wenzelm@44760
  2002
wenzelm@44777

  2005
    positions.
wenzelm@44760
  2006
wenzelm@44777

  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
  2008
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
  2009
    theory output and other non-Isabelle text boxes).
wenzelm@44777
  2010
wenzelm@44777
  2011
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
  2012
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
  2013
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
  2014
wenzelm@44777

    cores.
wenzelm@44760
  2017
wenzelm@44777

wenzelm@44800
  2026
The global load path (such as src/HOL/Library) has been discontinued.

  2027
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
  2028
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
  2029
INCOMPATIBILITY.
wenzelm@44800
  2030
wenzelm@41955

  2033
ISABELLE_FILE_IDENT plugin scripts.

Minor INCOMPATIBILITY, need to declare options in context like this:

  declare [[names_unique = false]]
wenzelm@42358
  2049
wenzelm@42502
  2050
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  2051
that the result needs to be unique, which means fact specifications
wenzelm@42502
  2052
may have to be refined after enriching a proof context.
wenzelm@42502
  2053
wenzelm@44800
  2054
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  2055
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  2056
wenzelm@44968
  2057
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  2058
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  2059
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968

  2249
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
  2250
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
  2251
huffman@44908
  2252
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
  2253
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
  2254
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
  2255
wenzelm@44968
  2256
* Code generation:
wenzelm@44968
  2257
wenzelm@44968
  2258
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
  2259
    characters in the target language.
wenzelm@44968
  2260
wenzelm@44968
  2261
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
  2262
    instead.
wenzelm@44968
  2263
wenzelm@44968
  2264
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
  2265
wenzelm@44968
  2266
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
  2267
    reactivated by the following theory command:
wenzelm@44968
  2268
wenzelm@44968
  2269
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
  2270
wenzelm@44968
  2271
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
  2272
wenzelm@45088
  2273
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
  2274
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
  2275
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
  2276
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
  2277
syntax.
wenzelm@45088
  2278
wenzelm@44968
  2279
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
  2280
still available as a legacy feature for some time.
wenzelm@44968
  2281
wenzelm@44968
  2282
* Nitpick:
wenzelm@44968
  2283
  - Added "need" and "total_consts" options.
wenzelm@44968
  2284
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
  2285
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
  2286
    INCOMPATIBILITY.
wenzelm@44968
  2287
wenzelm@44968
  2288
* Sledgehammer:
wenzelm@44968
  2289
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
  2290
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
  2291
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
  2292
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
  2293
    this can be done within reasonable time.
wenzelm@44968
  2294
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
  2295
    INCOMPATIBILITY.
wenzelm@44968
  2296
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
  2297
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
  2298
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
  2299
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
  2300
wenzelm@44968
  2301
* Metis:
wenzelm@44968
  2302
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
  2303
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
  2304
    INCOMPATIBILITY.
wenzelm@44968
  2305
wenzelm@44968
  2306
* Command 'try':
wenzelm@44968
  2307
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
  2308
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
  2309
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
  2310
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
  2311
wenzelm@44968
  2312
* Quickcheck:
wenzelm@44968
  2313
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
  2314
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  2315
  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
  2316
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  2317
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  2318
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968
  2319
    with its installation location defined in the Isabelle settings
wenzelm@44968
  2320
    environment as ISABELLE_GHC.
wenzelm@44968
  2321
  - Removed quickcheck tester "SML" based on the SML code generator
wenzelm@44968
  2322
    (formly in HOL/Library).
wenzelm@44968
  2323
wenzelm@44968
  2324
* Function package: discontinued option "tailrec".  INCOMPATIBILITY,
wenzelm@44968
  2325
use 'partial_function' instead.
wenzelm@44968
  2326
wenzelm@44968
  2327
* Theory Library/Extended_Reals replaces now the positive extended
wenzelm@44968
  2328
reals found in probability theory. This file is extended by
wenzelm@44968
  2329
Multivariate_Analysis/Extended_Real_Limits.
wenzelm@44968
  2330
wenzelm@44974
  2331
* Theory Library/Old_Recdef: old 'recdef' package has been moved here,
wenzelm@44974
  2332
from where it must be imported explicitly if it is really required.
wenzelm@44974
  2333
INCOMPATIBILITY.
wenzelm@44968
  2334
wenzelm@44968
  2335
* Theory Library/Wfrec: well-founded recursion combinator "wfrec" has
wenzelm@44968
  2336
been moved here.  INCOMPATIBILITY.
wenzelm@44968
  2337
wenzelm@44968
  2338
* Theory Library/Saturated provides type of numbers with saturated
wenzelm@44968
  2339
arithmetic.
wenzelm@44968
  2340
wenzelm@44968
  2341
* Theory Library/Product_Lattice defines a pointwise ordering for the
wenzelm@44968
  2342
product type 'a * 'b, and provides instance proofs for various order
wenzelm@44968
  2343
and lattice type classes.
wenzelm@44968
  2344
wenzelm@44968
  2345
* Theory Library/Countable now provides the "countable_datatype" proof
wenzelm@44968
  2346
method for proving "countable" class instances for datatypes.
wenzelm@44968
  2347
wenzelm@44968
  2348
* Theory Library/Cset_Monad allows do notation for computable sets
wenzelm@44968
  2349
(cset) via the generic monad ad-hoc overloading facility.
wenzelm@44968
  2350
wenzelm@44968

orthonormal basis for the type. Users now have the option of
wenzelm@44968

quantifying over this set instead of using the "basis" function, e.g.

wenzelm@44968
  2382
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  2383
changed to match. Definition theorems for overloaded constants now use

wenzelm@43731
  2513
* The inner syntax of sort/type/term/prop supports inlined YXML
wenzelm@43731
  2514
representations within quoted string tokens.  By encoding logical
wenzelm@43731
  2515
entities via Term_XML (in ML or Scala) concrete syntax can be
wenzelm@43731
  2516
bypassed, which is particularly useful for producing bits of text

* Inner syntax: identifiers in parse trees of generic categories
wenzelm@42056
  2536
"logic", "aprop", "idt" etc. carry position information (disguised as
wenzelm@42056
  2537
type constraints).  Occasional INCOMPATIBILITY with non-compliant
wenzelm@42057
  2538
translations that choke on unexpected type constraints.  Positions can
wenzelm@42057
  2539
be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  2540
Syntax.strip_positions_ast, or via the syntax constant
wenzelm@42057
  2541
"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  2542
be disabled via the configuration option Syntax.positions, which is
wenzelm@42057
  2543
called "syntax_positions" in Isar attribute syntax.

  2558
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  2559
wenzelm@42793
  2560
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  2561
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  2562
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  2563
snapshot of the classical context, which can be recovered via
wenzelm@42793
  2564
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.
wenzelm@42793

wenzelm@41612
  2614
like this:
wenzelm@41612
  2615
wenzelm@41612
  2616
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  2617
wenzelm@40948
  2618
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  2619
wenzelm@41594
  2620
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  2621
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  2622
while the default heap location within that directory lacks that extra
wenzelm@41594
  2623
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  2624
other, avoiding problems with old settings in new versions.
wenzelm@41594
  2625
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  2626
wenzelm@40947
  2627
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  2628
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  2629
the following package declarations:
wenzelm@40947
  2630
wenzelm@40947
  2631
  \usepackage[utf8]{inputenc}
wenzelm@40947
  2632
  \usepackage{textcomp}
wenzelm@40947
  2633
krauss@41440
  2634
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  2635
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  2636
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  2637
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  2638
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  2639
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  2640
merely give a byte-oriented representation.
wenzelm@37536
  2641
wenzelm@41594
  2642
* Theory loader: source files are primarily located via the master
wenzelm@41594
  2643
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  2644
The global load path is still partially available as legacy feature.
wenzelm@41594
  2645
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  2646
explicit paths, relatively to the theory.
wenzelm@38135
  2647
wenzelm@37939
  2648
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  2649
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  2650
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  2651
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  2652
wenzelm@38980
  2653
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  2654
handled within the context via configuration options, instead of
wenzelm@40879
  2655
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879
  2656
entities and Isar declaration attributes to access these.

  2684
changed globally at the ROOT session setup, but *not* within a theory.
wenzelm@40879
  2685
The option "show_abbrevs" supersedes the former print mode
wenzelm@40879
  2686
"no_abbrevs" with inverted meaning.
wenzelm@38767
  2687
wenzelm@40878
  2688
* More systematic naming of some configuration options.

wenzelm@40878
  2693
wenzelm@40291

* Support for real valued configuration options, using simplistic
wenzelm@40291
  2695
floating-point notation that coincides with the inner syntax for
wenzelm@40291
  2696
float_token.
wenzelm@40291
  2697
wenzelm@41594
  2698
* Support for real valued preferences (with approximative PGIP type):
wenzelm@41594
  2699
front-ends need to accept "pgint" values in float notation.

wenzelm@41573
  2704
wenzelm@41594
