60986  15 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  16 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
17 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

18 
'SML_file_no_debug' control compilation of sources with debugging 

19 
information. The Debugger panel allows to set breakpoints (via context 

20 
menu), step through stopped threads, evaluate local ML expressions etc. 

21 
At least one Debugger view needs to be active to have any effect on the 

22 
running ML program. 

23 

61173  24 
* The main Isabelle executable is managed as singleinstance Desktop 
25 
application uniformly on all platforms: Linux, Windows, Mac OS X. 

61170  26 

61198  27 
* The text overview column (status of errors, warnings etc.) is updated 
28 
asynchronously, leading to much better editor reactivity. Moreover, the 

29 
full document node content is taken into account. 

30 

61218  31 
* The State panel manages explicit proof state output, with jEdit action 
32 
"isabelle.updatestate" (shortcut S+ENTER) to trigger update according 

33 
to cursor position. Option "editor_output_state" controls implicit proof 

34 
state output in the Output panel: suppressing this reduces resource 

35 
requirements of prover time and GUI space.

* Local goals ('have', 'show', 'hence', 'thus') allow structured 
50

notation is postfix with keywords 'if' (or 'when') and 'for'. For

example:

54 
have result: "C x y" 

55 
if "A x" and "B y" 

56 
for x :: 'a and y :: 'a 

57 
<proof> 

58 

60449  59 
The local assumptions are bound to the name "that". The result is 
60 
exported from context of the statement as usual. The above roughly 

60414  61 
corresponds to a raw proof block like this: 
62 

63 
{ 

64 
fix x :: 'a and y :: 'a 

60449  65 
assume that: "A x" "B y" 
60414  66 
have "C x y" <proof> 
67 
}

72 

60595  73 
* The meaning of 'show' with Pure rule statements has changed: premises 
74 
are treated in the sense of 'assume', instead of 'presume'. This means, 

75 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

76 

77 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

78 

79 
or: 

80 

81 
show "C x" if "A x" "B x" for x 

82 

83 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

84 

85 
show "C x" when "A x" "B x" for x 

86 

60406  87 
* New command 'supply' supports fact definitions during goal refinement 
88 
('apply' scripts). 

89 

60459  90 
* New command 'consider' states rules for generalized elimination and 
91 
case splitting. This is like a toplevel statement "theorem obtains" used 

92 
within a proof body; or like a multibranch 'obtain' without activation 

93 
of the local context elements yet. 

94 

60455  95 
* Proof method "cases" allows to specify the rule as first entry of 
96 
chained facts. This is particularly useful with 'consider': 

97 

98 
consider (a) A  (b) B  (c) C <proof> 

99 
then have something 

100 
proof cases 

101 
case a 

102 
then show ?thesis <proof> 

103 
next 

104 
case b 

105 
then show ?thesis <proof> 

106 
next 

107 
case c 

108 
then show ?thesis <proof> 

109 
qed 

110 

60565  111 
* Command 'case' allows fact name and attribute specification like this: 
112 

113 
case a: (c xs) 

114 
case a [attributes]: (c xs) 

115 

116 
Facts that are introduced by invoking the case context are uniformly 

117 
qualified by "a"; the same name is used for the cumulative fact. The old 

118 
form "case (c xs) [attributes]" is no longer supported. Rare 

119 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

120 
and always put attributes in front.

60631  127 
* Command 'subgoal' allows to impose some structure on backward 
128 
refinements, to avoid proof scripts degenerating into long of 'apply' 

129 
sequences. Further explanations and examples are given in the isarref 

130 
manual.

60581  156 
* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  157 
is marked as legacy, and will be removed eventually. The proof method 
158 
"goals" achieves a similar effect within regular Isar; often it can be 

159 
done more adequately by other means (e.g. 'consider'). 

60581  160 

60551  161 
* Nesting of Isar goal structure has been clarified: the context after 
162 
the initial backwards refinement is retained for the whole proof, within 

163 
all its context sections (as indicated via 'next'). This is e.g. 

164 
relevant for 'using', 'including', 'supply': 

165 

166 
have "A \<and> A" if a: A for A 

167 
supply [simp] = a

* Method "sleep" succeeds after a realtime delay (in seconds). This is 
175 
occasionally useful for demonstration and testing purposes.

60331  178 
*** Pure ***

60489  180 
* The vacuous fact "TERM x" may be established "by fact" or as `TERM x` 
181 
as well, not just "by this" or "." as before. 

182 

60331  183 
* Configuration option rule_insts_schematic has been discontinued 
184 
(intermediate legacy feature in Isabelle2015). INCOMPATIBILITY. 

185 

60347  186 
* Abbreviations in type classes now carry proper sort constraint. 
187 
Rare INCOMPATIBILITY in situations where the previous misbehaviour 

61228  188 
has been exploited. 
60347  189 

190 
* Refinement of userspace type system in type classes: pseudolocal 

191 
operations behave more similar to abbreviations. Potential 

192 
INCOMPATIBILITY in exotic situations. 

193 

194 

60171  195 
*** HOL *** 
196 

61118  197 
* Qualification of various formal entities in the libraries is done more 
198 
uniformly via "context begin qualified definition ... end" instead of 

199 
oldstyle "hide_const (open) ...". Consequently, both the defined 

200 
constant and its defining fact become qualified, e.g. Option.is_none and 

201 
Option.is_none_def. Occasional INCOMPATIBILITY in applications.

* The alternative notation "\<Colon>" for type and sort constraints has been 
220 
removed: in LaTeX document output it looks the same as "::".

* Command 'experiment' opens an anonymous locale context with private 
423 
naming policy. 

424 

59951  425 
* Command 'notepad' requires proper nesting of begin/end and its proof 
426 
structure in the body: 'oops' is no longer supported here. Minor 

427 
INCOMPATIBILITY, use 'sorry' instead. 

428 

429 
* Command 'named_theorems' declares a dynamic fact within the context, 

430 
together with an attribute to maintain the content incrementally. This 

431 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

432 
of semantics due to external visual order vs. internal reverse order. 

433 

434 
* 'find_theorems': search patterns which are abstractions are 

435 
schematically expanded before search. Search results match the naive 

436 
expectation more closely, particularly wrt. abbreviations.

*** Document preparation *** 
493 

494 
* Document markup commands 'chapter', 'section', 'subsection', 

495 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

496 
context, even before the initial 'theory' command. Obsolete proof 

497 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

498 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

499 
instead. The old 'header' command is still retained for some time, but 

500 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

501 
update_header"). Minor INCOMPATIBILITY. 

502 

60009  503 
* Official support for "tt" style variants, via \isatt{...} or 
504 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

505 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

506 
as argument to other macros (such as footnotes). 

507 

508 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

509 
style. 

510 

511 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

512 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

513 

59951  514 
* Diagnostic commands and document markup commands within a proof do not 
515 
affect the command tag for output. Thus commands like 'thm' are subject 

516 
to proof document structure, and no longer "stick out" accidentally. 

517 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

518 
tags. Potential INCOMPATIBILITY in exotic situations. 

519 

520 
* System option "pretty_margin" is superseded by "thy_output_margin", 

521 
which is also accessible via document antiquotation option "margin". 

522 
Only the margin for document output may be changed, but not the global 

523 
pretty printing: that is 76 for plain console output, and adapted 

524 
dynamically in GUI frontends. Implementations of document 

525 
antiquotations need to observe the margin explicitly according to 

526 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* Lifting: command 'lift_definition' allows to execute lifted constants 
667 
that have as a return type a datatype containing a subtype. This 

668 
overcomes longtime limitations in the area of code generation and 

669 
lifting, and avoids tedious workarounds.

676 

677

678 
nontermination in case of distributing a division. With this change

701 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be

705 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

706 

707 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

708 
that admits numeric types including nat, int, real and complex. 

709 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

710 
constraint, and the combination "real (fact k)" is likely to be 

711 
unsatisfactory. If a type conversion is still necessary, then use 

712 
"of_nat (fact k)" or "real_of_nat (fact k)". 

713

715 
"nat o ceiling" instead. A few of the lemmas have been retained and 

716 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

717

* Subtle change of name space policy: undeclared entries are now 
819 
considered inaccessible, instead of accessible via the fullyqualified 

820 
internal name. This mainly affects Name_Space.intern (and derivatives), 

821 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  822 
contemporary applications use the strict Name_Space.check (and

Synchronized.var (which is usually sufficient in applications). Subtle

Toplevel bindings are stored within the theory context; the initial 

905

906

910 

57504  911 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
912 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

913 
variable. Locale assumptions and chained facts containing "x" 

914 
continue to be useful. The new method "hypsubst_thin" and the 

915 
configuration option "hypsubst_thin" (within the attribute name space) 

916 
restore the previous behavior. INCOMPATIBILITY, especially where 

917 
induction is done after these methods or when the names of free and 

918 
bound variables clash. As first approximation, old proofs may be 

919 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

920 

56232  921 
* More static checking of proof methods, which allows the system to 
922 
form a closure over the concrete syntax. Method arguments should be 

923 
processed in the original proof context as far as possible, before 

924 
operating on the goal state. In any case, the standard discipline for 

925 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

926 
number that is out of range produces an empty result sequence, not an 

927 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

928 
proof tools. 

929 

57452  930 
* Lexical syntax (inner and outer) supports text cartouches with 
931 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

932 
supports input via ` (backquote). 

933 

934 
* The outer syntax categories "text" (for formal comments and document 

935 
markup commands) and "altstring" (for literal fact references) allow 

936 
cartouches as well, in addition to the traditional mix of quotations. 

937 

938 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

939

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1027 
been discontinued to avoid the danger of nontrivial axiomatization 

1028 
that is not immediately visible. INCOMPATIBILITY, use regular 

1029 
'instance' command with proof. The required OFCLASS(...) theorem 

1030 
might be postulated via 'axiomatization' beforehand, or the proof 

1031 
finished trivially if the underlying class definition is made vacuous 

1032 
(without any assumptions). See also Isabelle/ML operations 

1033 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1034 
Axclass.arity_axiomatization. 

1035 

56245  1036 
* Basic constants of Pure use more conventional names and are always 
1037 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1038 
consequences, notably for tools in Isabelle/ML. The following 

1039 
renaming needs to be applied: 

1040 

1041 
== ~> Pure.eq 

1042 
==> ~> Pure.imp 

1043 
all ~> Pure.all 

1044 
TYPE ~> Pure.type 

1045 
dummy_pattern ~> Pure.dummy_pattern 

1046 

1047 
Systematic porting works by using the following theory setup on a 

1048 
*previous* Isabelle version to introduce the new name accesses for the 

1049 
old constants: 

1050 

1051 
setup {* 

1052 
fn thy => thy 

1053 
> Sign.root_path 

1054 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1055 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1056 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1057 
> Sign.restore_naming thy 

1058 
*} 

1059 

1060 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1061 
Later the application is moved to the current Isabelle version, and 

1062 
the auxiliary aliases are deleted.

* Obsolete attribute "standard" has been discontinued (legacy since

1070 
where instantiations with schematic variables are intended (for 

1071 
declaration commands like 'lemmas' or attributes like "of"). The 

1072 
following temporary definition may help to port old applications: 

1073

attribute_setup standard =

"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"

* New internal SAT solver "cdclite" that produces models and proof 
1286 
traces. This solver replaces the internal SAT solvers "enumerate" and 

1287 
"dpll". Applications that explicitly used one of these two SAT 

1288 
solvers should use "cdclite" instead. In addition, "cdclite" is now 

1289 
the default SAT solver for the "sat" and "satx" proof methods and 

1290 
corresponding tactics; the old default can be restored using "declare 

1291 
[[sat_solver = zchaff_with_proofs]]". Minor INCOMPATIBILITY. 

1292 

1293 
* SMT module: A new version of the SMT module, temporarily called 

1294 
"SMT2", uses SMTLIB 2 and supports recent versions of Z3 (e.g., 

1295 
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also 

1296 
supported as oracles. Yices is no longer supported, because no version 

1297 
of the solver can handle both SMTLIB 2 and quantifiers. 

1298 

1299 
* Activation of Z3 now works via "z3_non_commercial" system option 

1300 
(without requiring restart), instead of former settings variable 

1301 
"Z3_NON_COMMERCIAL". The option can be edited in Isabelle/jEdit menu 

1302 
Plugin Options / Isabelle / General. 

1303 

1304 
* Sledgehammer: 

1305 
 Z3 can now produce Isar proofs. 

1306 
 MaSh overhaul: 

57532  1307 
. New SMLbased learning algorithms eliminate the dependency on 
57508  1308 
Python and increase performance and reliability. 
1309 
. MaSh and MeSh are now used by default together with the 

1310 
traditional MePo (MengPaulson) relevance filter. To disable 

1311 
MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin 

1312 
Options / Isabelle / General to "none". 

1313 
 New option: 

1314 
smt_proofs

1320 

1321 
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead. 

1322 

1323 
* Nitpick: 

1324 
 Fixed soundness bug whereby mutually recursive datatypes could 

1325 
take infinite values. 

1326 
 Fixed soundness bug with lowlevel number functions such as 

1327 
"Abs_Integ" and "Rep_Integ". 

1328 
 Removed "std" option. 

1329 
 Renamed "show_datatypes" to "show_types" and "hide_datatypes" to 

1330 
"hide_types". 

1331 

1332 
* Metis: Removed legacy proof method 'metisFT'. Use 'metis 

1333 
(full_types)' instead. INCOMPATIBILITY. 

1334 

1335 
* Try0: Added 'algebra' and 'meson' to the set of proof methods. 

1336 

1337 
* Adjustion of INF and SUP operations: 

1338 
 Elongated constants INFI and SUPR to INFIMUM and SUPREMUM. 

1339 
 Consolidated theorem names containing INFI and SUPR: have INF and 

1340 
SUP instead uniformly. 

1341 
 More aggressive normalization of expressions involving INF and Inf 

1342 
or SUP and Sup. 

1343 
 INF_image and SUP_image do not unfold composition. 

1344 
 Dropped facts INF_comp, SUP_comp. 

1345 
 Default congruence rules strong_INF_cong and strong_SUP_cong, with 

1346 
simplifier implication in premises. Generalize and replace former 

1347 
INT_cong, SUP_cong

1350 

1351 
* SUP and INF generalized to conditionally_complete_lattice.

image_comp ~> image_comp [symmetric] 

1357 
vimage_compose ~> vimage_comp [symmetric]

1363 
Groups_Big.thy and Lattices_Big.thy. 

55098  1364
