*** General ***
wenzelm@51293
     8
wenzelm@53971
     9
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
    10
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
    11
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
    12
wenzelm@53971
    13
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
    14
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
    15
wenzelm@53016
    16
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
    17
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
    18
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
    19
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
    20
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
    21
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
    22
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
    23
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
    24
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
    25
syntax.
wenzelm@53016
    26
wenzelm@53021
    27
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
    28
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
    29
wenzelm@52487
    30
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
    31
"isabelle options"), configuration option within the context (see also
wenzelm@52487
    32
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
    33
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
    34
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
    35
wenzelm@52060
    36
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
    37
INCOMPATIBILITY.
wenzelm@52060
    38
wenzelm@52430
    39
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
    40
implicit change of some global references) is retained for now as
wenzelm@52430
    41
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
    42
wenzelm@52549
    43
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
    44
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
    45
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
    46
wenzelm@53971
    47
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
    48
eliminated old "ref" manual.
wenzelm@53971
    49
wenzelm@51293
    50
wenzelm@51533
    51
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
    52
wenzelm@53971
    53
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
    54
Documentation panel.
wenzelm@53852
    55
wenzelm@53971
    56
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
    57
documentation.
wenzelm@52646
    58
wenzelm@52949
    59
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
    60
(GUI front-end to 'find_theorems' command).
wenzelm@52949
    61
wenzelm@53050
    62
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
    63
sledgehammer runs over existing document sources, independently of
wenzelm@53050
    64
normal editing and checking process.
wenzelm@53050
    65
wenzelm@51533
    66
* Dockable window "Timing" provides an overview of relevant command
wenzelm@51533
    67
timing information.
wenzelm@51533
    68
wenzelm@53971
    69
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
    70
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
    71
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
    72
be marked explicitly as required and checked in full, using check box
wenzelm@53971
    73
or shortcut "C+e SPACE".
wenzelm@53971
    74
wenzelm@53971
    75
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
    76
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
    77
such command executions while editing.
wenzelm@53271
    78
wenzelm@53326
    79
* Improved completion mechanism, which is now managed by the
wenzelm@53981
    80
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@53981
    81
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@53326
    82
wenzelm@53971
    83
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
    84
document content.
wenzelm@53971
    85
wenzelm@53971
    86
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
    87
toplevel theorem statements.
wenzelm@53971
    88
wenzelm@53971
    89
* Action isabelle.reset-font-size resets main text area font size
wenzelm@53971
    90
according to Isabelle/Scala plugin option "jedit_font_reset_size"
wenzelm@53971
    91
(cf. keyboard shortcut C+0).
wenzelm@53971
    92
wenzelm@53971
    93
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@53971
    94
$ISABELLE_HOME on all platforms.  Discontinued obsolete
wenzelm@53971
    95
$ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
    96
wenzelm@53971
    97
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
    98
/ Global Options / Appearance".
wenzelm@53971
    99
wenzelm@53971
   100
* Improved support of native Mac OS X functionality via "MacOSX"
wenzelm@53971
   101
plugin, which is now enabled by default.
wenzelm@53971
   102
wenzelm@51533
   103
wenzelm@51313
   104
*** Pure ***
wenzelm@51313
   105
haftmann@51747
   106
* Target-sensitive commands 'interpretation' and 'sublocale'.
wenzelm@53971
   107
Particularly, 'interpretation' now allows for non-persistent
wenzelm@53160
   108
interpretation within "context ... begin ... end" blocks.  See
wenzelm@53160
   109
"isar-ref" manual for details.
haftmann@51747
   110
ballarin@51565
   111
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
   112
wenzelm@51313
   113
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
   114
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
   115
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
   116
wenzelm@51316
   117
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
   118
INCOMPATIBILITY.
wenzelm@51316
   119
wenzelm@53971
   120
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
   121
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
   122
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
   123
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
   124
wenzelm@53971
   125
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
   126
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
   127
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
   128
wenzelm@53971
   129
* Former global reference trace_unify_fail is now available as
wenzelm@53971
   130
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
   131
wenzelm@52463
   132
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
   133
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
   134
situations.
wenzelm@52463
   135
wenzelm@51313
   136
hoelzl@51002
   137
*** HOL ***
hoelzl@51002
   138
blanchet@53307
   139
* Improved support for ad hoc overloading of constants (see also
wenzelm@52896
   140
isar-ref manual and ~~/src/HOL/ex/Adhoc_Overloading_Examples.thy).
wenzelm@52896
   141
wenzelm@53160
   142
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@53160
   143
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@53160
   144
to distinguish both when desired.
haftmann@52637
   145
haftmann@52435
   146
* Code generator:
wenzelm@53160
   147
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
   148
    'code_instance'.
wenzelm@53160
   149
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
   150
    generated code, subsuming 'code_modulename'.
wenzelm@53983
   151
wenzelm@53983
   152
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
   153
examples.
haftmann@52435
   154
blanchet@53307
   155
* HOL/BNF:
blanchet@53728
   156
  - Various improvements to BNF-based (co)datatype package, including new
blanchet@54010
   157
    commands "primrec_new", "primcorec", and "datatype_new_compat",
blanchet@53766
   158
    as well as documentation. See "datatypes.pdf" for details.
blanchet@53307
   159
  - Renamed keywords:
blanchet@53307
   160
    data ~> datatype_new
blanchet@53307
   161
    codata ~> codatatype
blanchet@53307
   162
    bnf_def ~> bnf
blanchet@53307
   163
  - Renamed many generated theorems, including
blanchet@53728
   164
    discs ~> disc
blanchet@53307
   165
    map_comp' ~> map_comp
blanchet@53307
   166
    map_id' ~> map_id
blanchet@53728
   167
    sels ~> sel
blanchet@53307
   168
    set_map' ~> set_map
blanchet@53728
   169
    sets ~> set
blanchet@53307
   170
IMCOMPATIBILITY.
blanchet@53307
   171
kuncar@54021
   172
* Lifting:
kuncar@54021
   173
  - parametrized correspondence relations are now supported:
kuncar@54021
   174
    + parametricity theorems for the raw term can be specified in 
kuncar@54021
   175
      the command lift_definition, which allow us to generate stronger
kuncar@54021
   176
      transfer rules
kuncar@54021
   177
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
   178
      correspondence relation can be generated
kuncar@54021
   179
    + various new properties of the relator must be specified to support
kuncar@54021
   180
      parametricity
kuncar@54021
   181
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
   182
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
   183
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
   184
    copies
kuncar@54021
   185
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
   186
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
   187
    anonymous context)
kuncar@54021
   188
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in 
kuncar@54021
   189
    Main. Potential INCOMPATIBILITY
kuncar@54021
   190
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
   191
    lifting_forget, lifting_update
kuncar@54021
   192
  - the command print_quotmaps was renamed to print_quot_maps. 
kuncar@54021
   193
    INCOMPATIBILITY
kuncar@54021
   194
kuncar@54021
   195
* Transfer:
kuncar@54021
   196
  - better support for domains in Transfer: replace Domainp T 
kuncar@54021
   197
    by the actual invariant in a transferred goal
kuncar@54021
   198
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
   199
  - Experimental support for transferring from the raw level to the
kuncar@54021
   200
    abstract level: Transfer.transferred attribute
kuncar@54021
   201
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
   202
  
kuncar@54021
   203
krauss@53613
   204
* Function package: For mutually recursive functions f and g, separate
krauss@53613
   205
cases rules f.cases and g.cases are generated instead of unusable
krauss@53613
   206
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
krauss@53613
   207
in the case that the unusable rule was used nevertheless.
krauss@53613
   208
krauss@53613
   209
* Function package: For each function f, new rules f.elims are
krauss@53613
   210
automatically generated, which eliminate equalities of the form "f x =
krauss@53613
   211
t".
krauss@53613
   212
wenzelm@53983
   213
* New command 'fun_cases' derives ad-hoc elimination rules for
krauss@53613
   214
function equations as simplified instances of f.elims, analogous to
wenzelm@53983
   215
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
krauss@53613
   216
haftmann@52380
   217
* Library/Polynomial.thy:
wenzelm@53160
   218
  - Use lifting for primitive definitions.
wenzelm@53160
   219
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@53160
   220
    generated code.
wenzelm@53160
   221
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@53160
   222
  - Prefer pre-existing gcd operation for gcd.
wenzelm@53160
   223
  - Fact renames:
haftmann@52380
   224
    poly_eq_iff ~> poly_eq_poly_eq_iff
haftmann@52380
   225
    poly_ext ~> poly_eqI
haftmann@52380
   226
    expand_poly_eq ~> poly_eq_iff
blanchet@53307
   227
IMCOMPATIBILITY.
haftmann@52380
   228
kuncar@54021
   229
* New Library/FSet.thy: type of finite sets defined as a subtype of
kuncar@54021
   230
  sets defined by Lifting/Transfer
kuncar@54021
   231
haftmann@52286
   232
* Reification and reflection:
wenzelm@53160
   233
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
   234
    "Reification".
wenzelm@53160
   235
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
   236
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
   237
INCOMPATIBILITY.
haftmann@52286
   238
wenzelm@53983
   239
* Stronger precedence of syntax for big intersection and union on
wenzelm@53983
   240
sets, in accordance with corresponding lattice operations.
wenzelm@53983
   241
INCOMPATIBILITY.
haftmann@52141
   242
wenzelm@53160
   243
* Nested case expressions are now translated in a separate check phase
wenzelm@53160
   244
rather than during parsing. The data for case combinators is separated
wenzelm@53160
   245
from the datatype package. The declaration attribute
wenzelm@53160
   246
"case_translation" can be used to register new case combinators:
traytel@51682
   247
traytel@51682
   248
  declare [[case_translation case_combinator constructor1 ... constructorN]]
traytel@51682
   249
noschinl@53681
   250
* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
noschinl@53681
   251
case_of_simps to convert function definitions between a list of
noschinl@53681
   252
equations with patterns on the lhs and a single equation with case
noschinl@53681
   253
expressions on the rhs. See also Ex/Simps_Case_Conv_Examples.thy.
noschinl@53681
   254
wenzelm@51596
   255
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@51596
   256
haftmann@51489
   257
* Revised devices for recursive definitions over finite sets:
haftmann@51489
   258
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
   259
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
   260
    This is now identity on infinite sets.
wenzelm@52745
   261
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
   262
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
   263
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
   264
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
   265
    See theory Big_Operators for canonical examples.
haftmann@51489
   266
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
   267
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
   268
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
   269
    those foundational constants as substitutes, but it is
wenzelm@53983
   270
    preferable to interpret the above locales accordingly.
haftmann@51489
   271
  - Dropped class ab_semigroup_idem_mult (special case of lattice,

wenzelm@53160
   300
complete lattice but does not assume the existence of the top and
wenzelm@53160
   301
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
   302
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
   303
of conditionally_complete_lattice for real. Renamed lemmas about

   304
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
   305
Inf_...  to cInf_... to avoid hidding of similar complete lattice

wenzelm@53983
   324
 - Introduce type class (lin)order_topology and
wenzelm@53983
   325
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
   326
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
   327
hoelzl@51732
   328
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
   329
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
   330
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
   331
wenzelm@53983
   332
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
   333
   arbitrary filter.
wenzelm@53983
   334
wenzelm@53983
   335
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
   336
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
   337
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
   338
   continuous function is continuous, when the function is continuous
wenzelm@53983
   339
   on a compact set.
hoelzl@51732

   linear_continuum_topology).
hoelzl@51732
   344
hoelzl@51732
   345
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
   346
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
   347
   on all sequences converging to x.
wenzelm@53983
   348
wenzelm@53983
   349
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
   350
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
   351
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
   352
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
   353
   left or right.
hoelzl@51732
   354
hoelzl@51732
   355
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
   356
hoelzl@51732
   357
     F within X = inf F (principal X)
hoelzl@51732
   358
hoelzl@51732
   359
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
   360
   abbreviation for "at x within UNIV"
hoelzl@51732
   361
wenzelm@53983
   362
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
   363
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
   364
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
   365
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
   366
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
   367
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
   368
hoelzl@51732
   369
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
   370
hoelzl@51732
   371
   + Moved RealDef and RComplete into Real
hoelzl@51732
   372
hoelzl@51732

     topological spaces, filters, limits and continuity to it
hoelzl@51732
   375
hoelzl@51732
   376
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
   377
wenzelm@53983
   378
   + Split Lim, SEQ, Series into Topological_Spaces,

   379
     Real_Vector_Spaces, and Limits
hoelzl@51732
   380
hoelzl@51732
   381
   + Moved Ln and Log to Transcendental
hoelzl@51732
   382
hoelzl@51732
   383
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732

* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
   413
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983
   414
~~/src/HOL/Library/Polynomial instead.  The latter provides

wenzelm@53971
   420
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
   421
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
   422
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its

wenzelm@53971
   424
wenzelm@53709
   425
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709

tracing output in the command transaction context instead of physical
wenzelm@53709
   427

* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
   431
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
   432
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@53971
   433
Theory.checkpoint, and the auxiliary type theory_ref.  Minor

   434
INCOMPATIBILITY.
wenzelm@53164
   435
wenzelm@51551

Minor INCOMPATIBILITY.
wenzelm@51703
   442
wenzelm@51717
   443
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
   444
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
   445
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
   446
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
   447
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
   448
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
   449
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
   450
wenzelm@53971
   451
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
   452
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
   453
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
   454
clasets separately from the context.
wenzelm@53971
   455
wenzelm@51717

* Sessions may be organized via 'chapter' specifications in the ROOT

   502
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
   503
no longer printed by default, since it is incompatible with
wenzelm@50126
   504
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
   505
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
   506
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
   507
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
   508
accessible theorems in the theory context are finished (as before).
wenzelm@50126
   509
wenzelm@49699

* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
   511
into the printed representation of formal entities --- notably type
wenzelm@49699
   512
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
   513
information via tooltips in the output window, for example.
wenzelm@49699
   514
wenzelm@48890
   515
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
   516
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
   517
wenzelm@49243
   518
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
   519
theory header are legacy features and will be discontinued soon.
wenzelm@49243
   520
Tools that load their additional source files may imitate the
wenzelm@49243
   521
'ML_file' implementation, such that the system can take care of
wenzelm@49243
   522
dependencies properly.
wenzelm@49243
   523
wenzelm@47967
   524
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
   525
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
   526

   528
remaining material in old "ref" manual.
wenzelm@48120
   529
wenzelm@51050
   530
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
   531
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
   532
and "class ... context ...".
wenzelm@49841
   533
wenzelm@50772
   534
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
   535
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
   536
the target context.  This form of declaration is stable when exported
wenzelm@50772
   537
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
   538
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
   539
in HOL/inductive and HOL/function.

   540
wenzelm@49869

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
   549
wenzelm@49968
   550
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
   551
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
   552
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
   553
surface, while the prover is still crunching on internal
wenzelm@49968
   554
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
   555
required to complete full proof checking eventually.
wenzelm@49968
   556
wenzelm@49968
   557
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
   558
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
   559
tooltips leads to some window that supports the same recursively,
wenzelm@49968
   560
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
   561
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
   562
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
   563
wenzelm@50717
   564
* Improved support for commands that produce graph output: the text
wenzelm@50717
   565
message contains a clickable area to open a new instance of the graph
wenzelm@50717
   566
browser on demand.
wenzelm@50717
   567
wenzelm@49968
   568
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
   569
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
   570
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
   571
that frequently occur in user interaction.
wenzelm@49968
   572
wenzelm@49968
   573
* More efficient painting and improved reactivity when editing large
wenzelm@49968
   574
files.  More scalable management of formal document content.
wenzelm@49968
   575
wenzelm@50505
   576
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
   577
certain number of messages per command transaction, with some user
wenzelm@50505
   578
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
   579
potentially infinite message streams.
wenzelm@49968
   580
wenzelm@49968
   581
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
   582
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
   583
options, including tuning parameters for editor reactivity and color
wenzelm@49968
   584
schemes.
wenzelm@49968
   585
wenzelm@50184
   586
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
   587
symbols.
wenzelm@50184
   588
wenzelm@51082
   589
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
   590
continuous display of the chart slows down the system.
wenzelm@50701
   591
wenzelm@50183
   592
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
   593
bold, reset of style -- operating on single symbols or text
wenzelm@50198
   594
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
   595
wenzelm@50198
   596
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
   597
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
   598
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
   599
need to be adapted to local keyboard layouts.
wenzelm@50183
   600
wenzelm@50730
   601
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
   602
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
   603
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
   604
wenzelm@50406
   605
* Implicit check and build dialog of the specified logic session
wenzelm@50406
   606
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
   607
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
   608
Isabelle distribution.
wenzelm@50406
   609
wenzelm@49968
   610
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
   611
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
   612
now bundled exclusively with Isabelle.

* Code generation for Haskell: restrict unqualified imports from
haftmann@48431
   618
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
   619
wenzelm@50646
   620
* Command 'export_code': relative file names are interpreted
wenzelm@50646
   621
relatively to master directory of current theory rather than the
wenzelm@50646
   622
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
   623
wenzelm@48205
   624
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
   625
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
   626
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
   627
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
   628
with some care where this is really required.
wenzelm@48205
   629
wenzelm@48792
   630
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
   631
constraint, to infer and check the most general type conforming to a
wenzelm@51063
   632
given sort.  Example (in HOL):
wenzelm@48792
   633
wenzelm@48792
   634
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
   635
wenzelm@50716
   636
* Command 'locale_deps' visualizes all locales and their relations as
wenzelm@50716
   637
a Hasse diagram.

   642
* Sledgehammer:
wenzelm@50646
   643
wenzelm@50646
   644
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
   645
    Sledgehammer manual for details.
wenzelm@50646
   646
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
   647
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
   648
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
   649
  - Renamed options:
wenzelm@50646
   650
      isar_proof ~> isar_proofs
wenzelm@50646
   651
      isar_shrink_factor ~> isar_shrink
wenzelm@50646
   652
      max_relevant ~> max_facts

   653
      relevance_thresholds ~> fact_thresholds
wenzelm@50646
   654
wenzelm@50646
   655
* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
   656
switched on by default, and can be switched off by setting the
wenzelm@50646
   657
configuration quickcheck_optimise_equality to false.
wenzelm@50646

INCOMPATIBILITY.
kuncar@50878
   661
kuncar@50878
   662
* Lifting:
kuncar@50878
   663
  - generation of an abstraction function equation in lift_definition
kuncar@50878
   664
  - quot_del attribute
kuncar@50878
   665
  - renamed no_abs_code -> no_code (INCOMPATIBILITY.)
kuncar@50878
   666
wenzelm@50646
   667
* Simproc "finite_Collect" rewrites set comprehensions into pointfree
wenzelm@50646
   668
expressions.
wenzelm@50646
   669
wenzelm@50646
   670
* Preprocessing of the code generator rewrites set comprehensions into
wenzelm@50646
   671
pointfree expressions.
wenzelm@50646
   672
wenzelm@50646
   673
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
   674
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
   675
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
   676
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
   677
INCOMPATIBILITY.
haftmann@49948
   678
wenzelm@49836
   679
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
   680
set definition and alternative name have been discontinued.  The
wenzelm@49836
   681
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
   682
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
   683
accordingly.
wenzelm@49836
   684
wenzelm@50646
   685
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
   686
directly.  INCOMPATIBILITY.
wenzelm@50646
   687
wenzelm@50646
   688
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
   689
List.  INCOMPATIBILITY.
haftmann@49822
   690
haftmann@49739
   691
* Theorem UN_o generalized to SUP_comp.  INCOMPATIBILITY.
haftmann@49739
   692
haftmann@49738
   693
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
   694
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
   695
wenzelm@50646
   696
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
   697
wenzelm@50646
   698
* Theory "Transitive_Closure": renamed lemmas
wenzelm@50646

* Theory "Rings": renamed lemmas (in class semiring)
wenzelm@50646
   706
wenzelm@50646
   707
  left_distrib ~> distrib_right
wenzelm@50646
   708
  right_distrib ~> distrib_left
wenzelm@50646

   710
INCOMPATIBILITY.
wenzelm@50646
   711
wenzelm@50646
   712
* Generalized the definition of limits:
wenzelm@50646
   713
wenzelm@50646
   714
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
   715
    expresses that when the input values x converge to F then the
wenzelm@50646
   716
    output f x converges to G.
wenzelm@50646
   717
wenzelm@50646
   718
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
   719
    infinity (at_bot).
wenzelm@50646
   720
wenzelm@50646
   721
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
   722
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
   723
wenzelm@50646
   724
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
   725
    at_top".
wenzelm@50646
   726
wenzelm@50646
   727
INCOMPATIBILITY.
wenzelm@50646
   728
wenzelm@50646
   729
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
   730
lattice type classes.
wenzelm@50646
   731
wenzelm@50646
   732
* Theory "Library/Multiset": renamed
wenzelm@50646
   733
wenzelm@50646
   734
    constant fold_mset ~> Multiset.fold
wenzelm@50646
   735
    fact fold_mset_commute ~> fold_mset_comm
wenzelm@50646
   736
wenzelm@50646
   737
INCOMPATIBILITY.
wenzelm@50646
   738
wenzelm@50646
   739
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
   740
changes as follows.
wenzelm@50646
   741
wenzelm@50646
   742
  - Renamed constants (and related lemmas)
Christian@49145
   743
Christian@49145
   744
      prefix ~> prefixeq
Christian@49145
   745
      strict_prefix ~> prefix
Christian@49145
   746
wenzelm@50646
   747
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
   748
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
   749
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
   750
    Renamed lemmas accordingly.
wenzelm@50646
   751
wenzelm@50646
   752
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
   753
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
   754
    "list_hembeq (op =)".
wenzelm@50646
   755
wenzelm@50646
   756
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
   757
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
   758
    interpretations). The type class instances are now in theory
wenzelm@50646
   759
    Library/Prefix_Order.
wenzelm@50646
   760
wenzelm@50646
   761
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
   762
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516
   763
Christian@50516

wenzelm@50646
   783
* New theory Library/Countable_Set.
wenzelm@50646
   784
wenzelm@50646

wenzelm@50646
   788
* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
   789
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
   790
extensional_funcset by an abbreviation, and renamed lemmas from

   804
INCOMPATIBILITY.
wenzelm@50646

wenzelm@50646
   806
* Theory Library/FinFun: theory of almost everywhere constant
wenzelm@50646
   807
functions (supersedes the AFP entry "Code Generation for Functions as
wenzelm@50646
   808
Data").
wenzelm@50646
   809
wenzelm@50646
   810
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
   811
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
   812
TYPE('a) as another parameter avoids unnecessary closures in generated
wenzelm@50646
   813
code.
wenzelm@50646

wenzelm@50646
   815
* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646
   816
from sorted associative lists. Merging two trees with rbt_union may

on euclidean spaces by using the inner product "_ \<bullet> _" with
wenzelm@50646
   830
vectors from the Basis set: "\<Chi>\<Chi> i. f i" is superseded by

"SUM i : Basis. f i * r i".
wenzelm@50646
   832
wenzelm@50646

  With this change the following constants are also changed or removed:

* HOL/Probability:
wenzelm@50646
   858
wenzelm@50646
   859
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
   860
wenzelm@50646
   861
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
   862
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
   863
    (borel_measurable_induct).
wenzelm@50646
   864
wenzelm@50646
   865
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a
wenzelm@50646

with support for mixed, nested recursion and interesting non-free
wenzelm@50646
   873
datatypes.
blanchet@48094
   874
wenzelm@50991
   875
* HOL/Finite_Set and Relation: added new set and relation operations

   880
kuncar@50878
   881
* HOL/Library/RBT and HOL/Library/Mapping have been converted to
kuncar@50878

kuncar@50878
   883
possible INCOMPATIBILITY.

*** Document preparation ***
wenzelm@48206
   890
wenzelm@50646
   891
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
   892
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
   893
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
   894
wenzelm@50646
   895
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
   896
instead of slightly exotic babel/greek.
wenzelm@48206
   897
wenzelm@48616
   898
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
   899
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
   900
document/root.tex.
wenzelm@48616
   901
wenzelm@48657
   902
* Simplified custom document/build script, instead of old-style
wenzelm@48657
   903
document/IsaMakefile.  Minor INCOMPATIBILITY.

*** ML ***
wenzelm@48992
   907
wenzelm@50646
   908
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
   909
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
   910
hardware and Poly/ML runtime system.
wenzelm@50646
   911
wenzelm@49869
   912
* Type Seq.results and related operations support embedded error
wenzelm@49869
   913
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
   914
informative errors in the absence of any usable results.
wenzelm@49869
   915
wenzelm@48992
   916
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
   917
formal device to inline positions into message text, but not
wenzelm@48992
   918
necessarily printing visible text.

*** System ***
wenzelm@48206
   922
wenzelm@48585
   923
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
   924
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
   925
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
   926
session root directories for use with "isabelle build", similar to
wenzelm@51056
   927
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
   928
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
   929
mkdir / make are rendered obsolete.
wenzelm@48736
   930
wenzelm@51056
   931
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
   932
regular isabelle build tool.  For example:
wenzelm@51056
   933
wenzelm@51056
   934
  isabelle build -s -b HOL
wenzelm@51056
   935
wenzelm@48736
   936
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
   937
wenzelm@48722
   938
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
   939
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
   940
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
   941
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
   942
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
   943
wenzelm@48693
   944
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
   945
required for "isabelle build", for example.
wenzelm@48693
   946
wenzelm@50646
   947
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
   948
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
   949
wenzelm@50646
   950
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
   951
INCOMPATIBILITY.
wenzelm@50646
   952
wenzelm@48844
   953
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
   954
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
   955
version of Isabelle.
wenzelm@48844
   956
wenzelm@50646
   957
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
   958
platform family: "linux", "macos", "windows".
wenzelm@50646
   959
wenzelm@50646
   960
* The ML system is configured as regular component, and no longer
wenzelm@50646
   961
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
   962
for home-made settings.
wenzelm@50132
   963
wenzelm@50701
   964
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
   965
wenzelm@48206
   966
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
   967
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
   968
configuration.
wenzelm@48206
   969
wenzelm@48574
   970
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
   971
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
   972
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
   973
settings manually, or use a Proof General version that has been
wenzelm@48574
   974
bundled as Isabelle component.

wenzelm@45593
   981
*** General ***
wenzelm@45593
   982
wenzelm@45614
   983
* Prover IDE (PIDE) improvements:
wenzelm@45614
   984
wenzelm@47585
   985
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
   986
    command-line needs to be typed into the source buffer)
wenzelm@45614
   987
  - markup for bound variables
wenzelm@47806
   988
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
   989
  - support for user-defined Isar commands within the running session
wenzelm@47158
   990
  - improved support for Unicode outside original 16bit range
wenzelm@47158
   991
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
   992
wenzelm@47806
   993
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
   994
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
   995
commands to be used in the same theory where defined.
wenzelm@46485
   996
wenzelm@47482
   997
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
   998
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
   999
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  1000
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  1001
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  1002
wenzelm@47482
  1003
  context
wenzelm@47482
  1004
    fixes x y z :: 'a
wenzelm@47482
  1005
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  1006
  begin
wenzelm@47482
  1007
wenzelm@47482
  1008
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  1009
wenzelm@47482
  1010
  end
wenzelm@47482
  1011
wenzelm@47482
  1012
  thm my_trans
wenzelm@47482
  1013
wenzelm@47482
  1014
The most basic application is to factor-out context elements of
wenzelm@47482
  1015
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  1016
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  1017
wenzelm@47482
  1018
Any other local theory specification element works within the "context
wenzelm@47482
  1019
... begin ... end" block as well.
wenzelm@47482
  1020
wenzelm@47484
  1021
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  1022
given name in the context.  These may be later included in other
wenzelm@47484
  1023
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  1024
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  1025
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  1026
wenzelm@47829
  1027
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  1028
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  1029
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  1030
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  1031
indices of schematic variables.
wenzelm@47829
  1032
wenzelm@47829
  1033
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  1034
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  1035
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  1036
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  1037
etc. was exploited.
wenzelm@47829
  1038
wenzelm@47829
  1039
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  1040
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  1041
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  1042
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  1043
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  1044
of the material of that old tutorial.
wenzelm@47829
  1045
wenzelm@47829
  1046
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  1047
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  1048
manual.
wenzelm@47829
  1049
wenzelm@47829
  1050
wenzelm@47829
  1051
*** Pure ***
wenzelm@47829
  1052
wenzelm@46976
  1053
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  1054
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  1055
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  1056
wenzelm@47855
  1057
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  1058
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  1059
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  1060
undocumented feature.)
wenzelm@47855
  1061
wenzelm@47856
  1062
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  1063
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  1064
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  1065
wenzelm@47856
  1066
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  1067
wenzelm@47856
  1068
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  1069
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  1070
wenzelm@47856
  1071
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  1072
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  1073
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  1074
order to accommodate newly introduced premises.)
wenzelm@47856
  1075
wenzelm@47806
  1076
* Renamed some inner syntax categories:
wenzelm@47806
  1077
wenzelm@47806
  1078
    num ~> num_token
wenzelm@47806
  1079
    xnum ~> xnum_token
wenzelm@47806
  1080
    xstr ~> str_token
wenzelm@47806
  1081
wenzelm@47806
  1082
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  1083
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  1084
position information via constraints).
wenzelm@47806
  1085
wenzelm@47829
  1086
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  1087
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  1088
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  1089
wenzelm@47856
  1090
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  1091
in parse trees are always annotated by position constraints.
wenzelm@45134
  1092
wenzelm@47464
  1093
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  1094
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  1095
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  1096
wenzelm@47464
  1097
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  1098
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464

* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464

"code_abbrev", which yields a common pattern in definitions like

instead.  INCOMPATIBILITY.
wenzelm@47856
  1109
wenzelm@47856
  1110
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  1111
collection of foundational premises in the context (already marked as
wenzelm@47856
  1112
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  1118
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  1119
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  1120
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  1121
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  1122
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  1123
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  1124
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  1125
possible.
wenzelm@47855
  1126
wenzelm@47855
  1127
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  1128
planning step is necessary to determine what should become a predicate
wenzelm@47464
  1129
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  1130
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  1131
wenzelm@47855
  1132
* Code generation by default implements sets as container type rather
wenzelm@47855
  1133
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  1134
wenzelm@47855

* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855

wenzelm@47464
  1137
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  1138
represents strictly positive binary numerals, along with functions
wenzelm@47464
  1139
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  1140
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  1141
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  1142
user theories may require adaptations as follows:
huffman@47108
  1143
huffman@47108
  1144
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  1145
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  1146
huffman@47108
  1147
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  1148
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  1149
    after classes one and semigroup_add have been instantiated.
huffman@47108
  1150
huffman@47108
  1151
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  1152
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  1153
huffman@47108
  1154
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  1155
    automatically support numerals now, so more simp rules and
huffman@47108
  1156
    simprocs may now apply within the proof.
huffman@47108
  1157
huffman@47108
  1158
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
  1159
    Redefine using other integer operations.
huffman@47108
  1160
wenzelm@47855
  1161
* Transfer: New package intended to generalize the existing
wenzelm@47855
  1162
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  1163
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  1164
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  1165
corresponding parts of the Quotient package.)
wenzelm@47809
  1166
wenzelm@47809
  1167
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  1168
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  1169
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  1170
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  1171
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  1172
wenzelm@47809
  1173
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  1174
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  1175
wenzelm@47809
  1176
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  1177
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  1178
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  1179
    Goals are generalized over all free variables by default; this is
huffman@47851
  1180
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  1181
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  1182
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  1183
    is logically stronger (rather than equivalent).
wenzelm@47809
  1184
wenzelm@47809
  1185
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  1186
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  1187
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  1188
    non-polymorphic constants on the fly.
wenzelm@47809
  1189
wenzelm@47809
  1190
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  1191
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  1192
    constants that already have transfer rules. It should be applied
wenzelm@47809
  1193
    after unfolding the constant definitions.

wenzelm@47809

huffman@47851
  1198
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  1199
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  1200
wenzelm@47809
  1201
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  1202
    terms of a corresponding operation on a representation
wenzelm@47809
  1203
    type.  Example syntax:
wenzelm@47809
  1204
wenzelm@47809
  1205
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  1206
      is List.insert
wenzelm@47809
  1207
wenzelm@47809
  1208
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  1209
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  1210
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  1211
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  1212
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  1213
    by the package.
wenzelm@47809
  1214
wenzelm@47809
  1215
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  1216
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  1217
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  1218
    code generation for each constant.
wenzelm@47809
  1219
wenzelm@47809
  1220
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  1221
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  1222
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  1223
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  1224
    lift_definition command to work with the type.
wenzelm@47809
  1225
wenzelm@47809
  1226
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  1227
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  1228
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  1229
wenzelm@47809
  1230
* Quotient package:
wenzelm@47809
  1231
wenzelm@47809
  1232
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  1233
    rep and abs functions, similar to typedef.
wenzelm@47809
  1234
wenzelm@47809
  1235
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  1236
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  1237
wenzelm@47809
  1238
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  1239
    respectfulness property at the point where the constant is
wenzelm@47809
  1240
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  1241
wenzelm@47809
  1242
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  1243
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  1244
wenzelm@47809
  1245
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  1246
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  1247
wenzelm@47809
  1248
* Quickcheck:
wenzelm@47809
  1249
wenzelm@47809
  1250
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  1251
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  1252
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  1253
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  1254
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  1255
wenzelm@47809
  1256
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  1257
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  1258
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  1259
wenzelm@47809
  1260
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  1261
    continues searching for genuine ones.
wenzelm@47809
  1262
wenzelm@47809
  1263
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  1264
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  1265
    show genuine counterexamples.
wenzelm@47809
  1266
wenzelm@47809
  1267
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  1268
    value generators for a given type and operations.
wenzelm@47809
  1269
wenzelm@47809
  1270
    It generates values by using the operations as if they were
wenzelm@47809
  1271
    constructors of that type.
wenzelm@47809
  1272
wenzelm@47809
  1273
  - Support for multisets.
wenzelm@47809
  1274
wenzelm@47809
  1275
  - Added "use_subtype" options.
wenzelm@47809
  1276
wenzelm@47809
  1277
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  1278
    conjectures in a locale context.
wenzelm@47809
  1279
wenzelm@47855
  1280
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  1281
and affecting 'rat' and 'real'.
wenzelm@47809
  1282
wenzelm@47809
  1283
* Sledgehammer:
wenzelm@47809
  1284
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  1285
    paper "More SPASS with Isabelle".
wenzelm@47809
  1286
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  1287
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  1288
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  1289
  - Sped up the minimizer.
wenzelm@47809
  1290
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  1291
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  1292
  - Renamed "sound" option to "strict".
wenzelm@47809
  1293
wenzelm@47855
  1294
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  1295
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  1296
wenzelm@47855
  1297
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  1298
wenzelm@47855
  1299
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  1300
wenzelm@47856
  1301
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  1302
case distinctions at the same time.  E.g.
wenzelm@47856
  1303
wenzelm@47856
  1304
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  1305
wenzelm@47856
  1306
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  1307
a list and a nat.
wenzelm@47856
  1308
wenzelm@47809
  1309
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  1310
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  1311
wenzelm@47702
  1312
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  1313
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  1314
default.
wenzelm@47702
  1315
wenzelm@47856
  1316
* Record: code generation can be switched off manually with
wenzelm@47856
  1317
wenzelm@47856
  1318
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
  1319
wenzelm@47856
  1320
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
  1321
wenzelm@47855
  1322
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
  1323
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
  1324
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
  1325
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
  1326
one_case.
wenzelm@47855
  1327
wenzelm@47855
  1328
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
  1329
the result of the fact expression.
wenzelm@47855
  1330
haftmann@46752
  1331
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
  1332
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
  1333
of some relation theorems:
haftmann@46752
  1334
haftmann@46752
  1335
  converse_def ~> converse_unfold
haftmann@47549
  1336
  rel_comp_def ~> relcomp_unfold

  1340
  Range_def ~> Domain_converse [symmetric]
haftmann@46752
  1341
haftmann@46981
  1342
Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
  1343
wenzelm@47464
  1344
See theory "Relation" for examples for making use of pred/set
wenzelm@47464
  1345
conversions by means of attributes "to_set" and "to_pred".
haftmann@47086
  1346
haftmann@46752
  1347
INCOMPATIBILITY.
haftmann@46752
  1348
bulwahn@46363
  1349
* Renamed facts about the power operation on relations, i.e., relpow
wenzelm@47464
  1350
to match the constant's name:
wenzelm@47463
  1351
wenzelm@46458

  rel_pow_1 ~> relpow_1
bulwahn@46363

wenzelm@47809
  1785
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  1786
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  1787
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  1788
constants.  Requires fixed-length word types, not 'a word.  Solves

  1789
many standard word identities outright and converts more into first

  1790

* Session HOL-Probability: Introduced the type "'a measure" to
wenzelm@47807
  1794
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807
  1795
measure_space.  The locales based on subset_class now have two
wenzelm@47856
  1796
locale-parameters the space \<Omega> and the set of measurable sets M.
wenzelm@47856
  1797
The product of probability spaces uses now the same constant as the
wenzelm@47856
  1798
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  1799
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  1800
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  1801
Measure space constructions for distributions and densities now got
wenzelm@47807
  1802
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  1803
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  1804
and point_measure is introduced.  INCOMPATIBILITY.

usedir option -Q.
wenzelm@41703
  2098
wenzelm@42669
  2099
* Name space: former unsynchronized references are now proper
wenzelm@42669
  2100
configuration options, with more conventional names:

  unique_names ~> names_unique
wenzelm@42669
  2105
wenzelm@42669
  2106
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669

wenzelm@42669
  2108
  declare [[names_unique = false]]
wenzelm@42358
  2109
wenzelm@42502
  2110
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  2111
that the result needs to be unique, which means fact specifications
wenzelm@42502
  2112
may have to be refined after enriching a proof context.
wenzelm@42502
  2113
wenzelm@44800
  2114
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  2115
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  2116
wenzelm@44968
  2117
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  2118
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  2119
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
  2120
  - Updated material from classic "ref" manual, notably about
wenzelm@44968
  2121
    "Classical Reasoner".

  2129
* Class complete_lattice: generalized a couple of lemmas from sets;
wenzelm@44800
  2130
generalized theorems INF_cong and SUP_cong.  New type classes for
wenzelm@44800
  2131
complete boolean algebras and complete linear orders.  Lemmas
wenzelm@44800
  2132
Inf_less_iff, less_Sup_iff, INF_less_iff, less_SUP_iff now reside in
wenzelm@44800
  2133
class complete_linorder.
wenzelm@44800
  2134
wenzelm@44800
  2135
Changed proposition of lemmas Inf_bool_def, Sup_bool_def, Inf_fun_def,

Sup_fun_def, Inf_apply, Sup_apply.
wenzelm@44800

INCOMPATIBILITY.
wenzelm@44973

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

wenzelm@44973
  2185
INCOMPATIBILITY.
wenzelm@44973
  2186
krauss@44845
  2187
* Added syntactic classes "inf" and "sup" for the respective

  2189
(mostly internal) locale predicates for some derived classes.

wenzelm@44800
  2193
UN_ball_bex_simps.  INCOMPATIBILITY.
wenzelm@44800

separate type class floor_ceiling.
wenzelm@44800
  2197
wenzelm@44800

adjustment.  INCOMPATIBILITY.
haftmann@42874
  2205
wenzelm@44800

bounded_linear and bounded_bilinear locales have been removed, in
wenzelm@44800
  2211

* Theory Complex_Main: The definition of infinite series was
wenzelm@44967
  2309
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
  2310
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
  2311
huffman@44908
  2312
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
  2313
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
  2314
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
  2315
wenzelm@44968
  2316
* Code generation:
wenzelm@44968
  2317
wenzelm@44968
  2318
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
  2319
    characters in the target language.
wenzelm@44968
  2320
wenzelm@44968
  2321
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
  2322
    instead.
wenzelm@44968
  2323
wenzelm@44968
  2324
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
  2325
wenzelm@44968
  2326
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
  2327
    reactivated by the following theory command:
wenzelm@44968
  2328
wenzelm@44968
  2329
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
  2330
wenzelm@44968
  2331
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
  2332
wenzelm@45088
  2333
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
  2334
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
  2335
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
  2336
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
  2337
syntax.
wenzelm@45088
  2338
wenzelm@44968
  2339
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
  2340
still available as a legacy feature for some time.
wenzelm@44968
  2341
wenzelm@44968
  2342
* Nitpick:
wenzelm@44968
  2343
  - Added "need" and "total_consts" options.
wenzelm@44968
  2344
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
  2345
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
  2346
    INCOMPATIBILITY.
wenzelm@44968
  2347
wenzelm@44968
  2348
* Sledgehammer:
wenzelm@44968
  2349
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
  2350
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
  2351
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
  2352
  - Automatically preplay and minimize proofs before showing them if

wenzelm@44968
  2434
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  2435
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

* Typed print translation: discontinued show_sorts argument, which is
wenzelm@42247
  2612
already available via context of "advanced" translation.
wenzelm@42247
  2613
wenzelm@42370
  2614
* Refined PARALLEL_GOALS tactical: degrades gracefully for schematic
wenzelm@42370
  2615
goal states; body tactic needs to address all subgoals uniformly.
wenzelm@42370
  2616
wenzelm@42403
  2617
* Slightly more special eq_list/eq_set, with shortcut involving
wenzelm@42403
  2618
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  2619
wenzelm@42793
  2620
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  2621
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  2622
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  2623
snapshot of the classical context, which can be recovered via
wenzelm@42793
  2624
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.
wenzelm@42793
  2625
INCOMPATIBILITY, classical tactics and derived proof methods require
wenzelm@42793
  2626
proper Proof.context.

*** System ***
wenzelm@44803
  2630
wenzelm@44968
  2631
* Discontinued support for Poly/ML 5.2, which was the last version
wenzelm@44968
  2632
without proper multithreading and TimeLimit implementation.
wenzelm@44968
  2633
wenzelm@44968
  2634
* Discontinued old lib/scripts/polyml-platform, which has been
wenzelm@44968
  2635
obsolete since Isabelle2009-2.
wenzelm@44968
  2636
wenzelm@44967
  2637
* Various optional external tools are referenced more robustly and
wenzelm@44967
  2638
uniformly by explicit Isabelle settings as follows:
wenzelm@44967
  2639
wenzelm@44967
  2640
  ISABELLE_CSDP   (formerly CSDP_EXE)
wenzelm@44967
  2641
  ISABELLE_GHC    (formerly EXEC_GHC or GHC_PATH)
wenzelm@44967
  2642
  ISABELLE_OCAML  (formerly EXEC_OCAML)
wenzelm@44967
  2643
  ISABELLE_SWIPL  (formerly EXEC_SWIPL)
wenzelm@44967
  2644
  ISABELLE_YAP    (formerly EXEC_YAP)
wenzelm@44967
  2645
wenzelm@44967
  2646
Note that automated detection from the file-system or search path has
wenzelm@44967
  2647
been discontinued.  INCOMPATIBILITY.
wenzelm@44967
  2648
wenzelm@43752
  2649
* Scala layer provides JVM method invocation service for static
wenzelm@44800
  2650
methods of type (String)String, see Invoke_Scala.method in ML.  For
wenzelm@44800
  2651
example:
wenzelm@43752
  2652
wenzelm@43752
  2653
  Invoke_Scala.method "java.lang.System.getProperty" "java.home"
wenzelm@43752
  2654
wenzelm@44967
  2655
Together with YXML.string_of_body/parse_body and XML.Encode/Decode
wenzelm@44967
  2656
this allows to pass structured values between ML and Scala.
wenzelm@44800
  2657
wenzelm@44803
  2658
* The IsabelleText fonts includes some further glyphs to support the
wenzelm@44803
  2659
Prover IDE.  Potential INCOMPATIBILITY: users who happen to have
wenzelm@44803
  2660
installed a local copy (which is normally *not* required) need to
wenzelm@44803
  2661
delete or update it from ~~/lib/fonts/.

*** General ***
wenzelm@37536
  2669
wenzelm@41573
  2670
* Experimental Prover IDE based on Isabelle/Scala and jEdit (see
wenzelm@41612
  2671
src/Tools/jEdit).  This also serves as IDE for Isabelle/ML, with
wenzelm@41612
  2672
useful tooltips and hyperlinks produced from its static analysis.  The
wenzelm@41612
  2673
bundled component provides an executable Isabelle tool that can be run
wenzelm@41612
  2674
like this:
wenzelm@41612
  2675
wenzelm@41612
  2676
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  2677
wenzelm@40948
  2678
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  2679
wenzelm@41594
  2680
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  2681
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  2682
while the default heap location within that directory lacks that extra
wenzelm@41594
  2683
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  2684
other, avoiding problems with old settings in new versions.
wenzelm@41594
  2685
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  2686
wenzelm@40947
  2687
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  2688
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  2689
the following package declarations:
wenzelm@40947
  2690
wenzelm@40947
  2691
  \usepackage[utf8]{inputenc}
wenzelm@40947
  2692
  \usepackage{textcomp}
wenzelm@40947
  2693
krauss@41440
  2694
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  2695
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  2696
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  2697
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  2698
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  2699
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  2700
merely give a byte-oriented representation.
wenzelm@37536
  2701
wenzelm@41594
  2702
* Theory loader: source files are primarily located via the master
wenzelm@41594
  2703
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  2704
The global load path is still partially available as legacy feature.
wenzelm@41594
  2705
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  2706
explicit paths, relatively to the theory.
wenzelm@38135
  2707
wenzelm@37939
  2708
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  2709
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  2710
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  2711
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  2712
wenzelm@38980
  2713
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  2714
handled within the context via configuration options, instead of
wenzelm@40879
  2715
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879
  2716
entities and Isar declaration attributes to access these.
wenzelm@38767
