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 

61215  31 
* The State panel manages implicit proof state output, with jEdit action 
32 
"isabelleupdatestate" to trigger update according to cursor position. 

33 
Option "editor_output_state" controls implicit proof state output in the 

34 
Output panel: suppressing this may reduce resource requirements of 

35 
prover time and GUI space.

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 *** 
179 

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 

188 
has been exploited previously. 

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.

* Command 'experiment' opens an anonymous locale context with private 
429 
naming policy. 

430 

59951  431

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

436 
together with an attribute to maintain the content incrementally. This 

437 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
499 

500 
* Document markup commands 'chapter', 'section', 'subsection', 

501 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

502 
context, even before the initial 'theory' command. Obsolete proof 

503 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

504 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

505 
instead. The old 'header' command is still retained for some time, but 

506 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

507 
update_header"). Minor INCOMPATIBILITY. 

508 

60009  509 
* Official support for "tt" style variants, via \isatt{...} or 
510 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

511 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

512 
as argument to other macros (such as footnotes). 

513 

514 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

515 
style. 

516 

517 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

518 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

519 

59951  520 
* Diagnostic commands and document markup commands within a proof do not 
521 
affect the command tag for output. Thus commands like 'thm' are subject 

522 
to proof document structure, and no longer "stick out" accidentally. 

523 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

524 
tags. Potential INCOMPATIBILITY in exotic situations. 

525 

526 
* System option "pretty_margin" is superseded by "thy_output_margin", 

527 
which is also accessible via document antiquotation option "margin". 

528 
Only the margin for document output may be changed, but not the global 

529 
pretty printing: that is 76 for plain console output, and adapted 

530 
dynamically in GUI frontends. Implementations of document 

531 
antiquotations need to observe the margin explicitly according to 

532 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

 Proof reconstruction, both oneliners and Isar, has been 
59039  654 
dramatically improved. 
655 
 Improved support for CVC4 and veriT.

58062  657 
* Old and new SMT modules: 
58067  658 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  659 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
660 
until applications have been ported to use the new 'smt' method. For 

661 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

662 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

663 
point to it. 

58062  664 
INCOMPATIBILITY. 
58067  665 
 The 'smt2' method has been renamed 'smt'. 
58060  666 
INCOMPATIBILITY. 
59569  667 
 New option 'smt_reconstruction_step_timeout' to limit the 
668 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  669 
 New option 'smt_statistics' to display statistics of the new 'smt' 
670 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  671 

60261  672 
* Lifting: command 'lift_definition' allows to execute lifted constants 
673 
that have as a return type a datatype containing a subtype. This 

674 
overcomes longtime limitations in the area of code generation and 

675 
lifting, and avoids tedious workarounds. 

60258  676 

60009  677 
* Command and antiquotation "value" provide different evaluation slots 
678 
(again), where the previous strategy (NBE after ML) serves as default. 

679 
Minor INCOMPATIBILITY. 

680 

681 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

682 

683 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

684 
nontermination in case of distributing a division. With this change 

685 
field_simps is in some cases slightly less powerful, if it fails try to 

686 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

687 

688 
* Separate class no_zero_divisors has been given up in favour of fully 

689 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY. 

690 

691 
* Class linordered_semidom really requires no zero divisors. 

692 
INCOMPATIBILITY. 

693 

694 
* Classes division_ring, field and linordered_field always demand 

695 
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero, 

696 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY. 

697 

698 
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit 

699 
additive inverse operation. INCOMPATIBILITY.

* The functions "sin" and "cos" are now defined for any type of sort 
706 
"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

707 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be 

708

709 

710 
* New library of properties of the complex transcendental functions sin, 

711 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

712 

713 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

714 
that admits numeric types including nat, int, real and complex. 

715 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

716 
constraint, and the combination "real (fact k)" is likely to be 

717 
unsatisfactory. If a type conversion is still necessary, then use 

718 
"of_nat (fact k)" or "real_of_nat (fact k)". 

719 

720 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

721 
"nat o ceiling" instead. A few of the lemmas have been retained and 

722 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

723 
"nat_floor"/"nat_ceiling". 

724 

725 
* Qualified some duplicated fact names required for boostrapping the 

726 
type class hierarchy: 

727

728 
field_inverse_zero ~> inverse_zero 

729 
field_divide_inverse ~> divide_inverse 

730

734 
mult_less_imp_less_right ~> mult_right_less_imp_less 

735 
mult_less_imp_less_left ~> mult_left_less_imp_less 

736 
Minor INCOMPATIBILITY. 

737 

738 
* Fact consolidation: even_less_0_iff is subsumed by 

739 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

740 

741 
* Generalized and consolidated some theorems concerning divsibility: 

742 
dvd_reduce ~> dvd_add_triv_right_iff 

743 
dvd_plus_eq_right ~> dvd_add_right_iff 

744 
dvd_plus_eq_left ~> dvd_add_left_iff 

745

60009  824 
* Subtle change of name space policy: undeclared entries are now 
825 
considered inaccessible, instead of accessible via the fullyqualified 

826 
internal name. This mainly affects Name_Space.intern (and derivatives), 

827 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  828 
contemporary applications use the strict Name_Space.check (and 
60009  829 
derivatives) instead, which is not affected by the change. Potential 
830 
INCOMPATIBILITY in rare applications of Name_Space.intern. 

59951  831

839 
INCOMPATIBILITY. 

840 

841 
* Former combinators NAMED_CRITICAL and CRITICAL for central critical 

842

843 
Multithreading.synchronized and its highlevel derivative 

844 
Synchronized.var (which is usually sufficient in applications). Subtle 

845 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

846 
nested. 

847 

60009  848

* Standard tactics and proof methods such as "clarsimp", "auto" and

920 
continue to be useful. The new method "hypsubst_thin" and the 

921 
configuration option "hypsubst_thin" (within the attribute name space) 

922 
restore the previous behavior. INCOMPATIBILITY, especially where 

923 
induction is done after these methods or when the names of free and 

924 
bound variables clash. As first approximation, old proofs may be 

925 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

926 

56232  927 
* More static checking of proof methods, which allows the system to 
928 
form a closure over the concrete syntax. Method arguments should be 

929 
processed in the original proof context as far as possible, before 

930 
operating on the goal state. In any case, the standard discipline for

* Lexical syntax (inner and outer) supports text cartouches with 
937 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

938 
supports input via ` (backquote). 

939 

940 
* The outer syntax categories "text" (for formal comments and document 

941 
markup commands) and "altstring" (for literal fact references) allow 

942 
cartouches as well, in addition to the traditional mix of quotations. 

943 

944 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

945 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  946 
string token. General renovation of its syntax using text cartouches. 
57452  947 
Minor INCOMPATIBILITY. 
948 

949 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

950 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

951 
old identifier syntax with \<^isub> or \<^isup>. Potential 

952 
INCOMPATIBILITY. 

953 

954 
* Document antiquotation @{url} produces markup for the given URL, 

955 
which results in an active hyperlink within the text. 

956 

957 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

958 
not check existence within the filesystem. 

959 

960

961 
isarref, jedit, system.

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1033 
been discontinued to avoid the danger of nontrivial axiomatization 

1034 
that is not immediately visible. INCOMPATIBILITY, use regular 

1035 
'instance' command with proof. The required OFCLASS(...) theorem 

1036 
might be postulated via 'axiomatization' beforehand, or the proof 

1037 
finished trivially if the underlying class definition is made vacuous 

1038 
(without any assumptions). See also Isabelle/ML operations 

1039 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1040 
Axclass.arity_axiomatization. 

1041 

56245  1042 
* Basic constants of Pure use more conventional names and are always 
1043 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1044 
consequences, notably for tools in Isabelle/ML. The following 

1045 
renaming needs to be applied: 

1046 

1047 
== ~> Pure.eq 

1048 
==> ~> Pure.imp 

1049 
all ~> Pure.all 

1050 
TYPE ~> Pure.type 

1051 
dummy_pattern ~> Pure.dummy_pattern 

1052 

1053 
Systematic porting works by using the following theory setup on a 

1054 
*previous* Isabelle version to introduce the new name accesses for the 

1055 
old constants: 

1056 

1057 
setup {* 

1058 
fn thy => thy 

1059 
> Sign.root_path 

1060 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1061 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1062 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1063 
> Sign.restore_naming thy 

1064 
*} 

1065 

1066 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1067 
Later the application is moved to the current Isabelle version, and 

1068 
the auxiliary aliases are deleted.

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

1076 
where instantiations with schematic variables are intended (for 

1077 
declaration commands like 'lemmas' or attributes like "of"). The 

1078

* New internal SAT solver "cdclite" that produces models and proof 
1292 
traces. This solver replaces the internal SAT solvers "enumerate" and 

1293 
"dpll". Applications that explicitly used one of these two SAT 

1294 
solvers should use "cdclite" instead. In addition, "cdclite" is now 

1295 
the default SAT solver for the "sat" and "satx" proof methods and 

1296 
corresponding tactics; the old default can be restored using "declare 

1297 
[[sat_solver = zchaff_with_proofs]]". Minor INCOMPATIBILITY. 

1298 

1299 
* SMT module: A new version of the SMT module, temporarily called 

1300 
"SMT2", uses SMTLIB 2 and supports recent versions of Z3 (e.g., 

1301 
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also 

1302 
supported as oracles. Yices is no longer supported, because no version 

1303 
of the solver can handle both SMTLIB 2 and quantifiers. 

1304 

1305 
* Activation of Z3 now works via "z3_non_commercial" system option 

1306 
(without requiring restart), instead of former settings variable 

1307 
"Z3_NON_COMMERCIAL". The option can be edited in Isabelle/jEdit menu 

1308 
Plugin Options / Isabelle / General. 

1309 

1310 
* Sledgehammer: 

1311 
 Z3 can now produce Isar proofs. 

1312 
 MaSh overhaul: 

57532  1313 
. New SMLbased learning algorithms eliminate the dependency on 
57508  1314 
Python and increase performance and reliability. 
1315 
. MaSh and MeSh are now used by default together with the 

1316 
traditional MePo (MengPaulson) relevance filter. To disable 

1317 
MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin 

1318 
Options / Isabelle / General to "none". 

1319 
 New option: 

1320 
smt_proofs 

1321 
 Renamed options: 

1322

1326 

1327 
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead. 

1328 

1329 
* Nitpick: 

1330 
 Fixed soundness bug whereby mutually recursive datatypes could 

1331 
take infinite values. 

1332 
 Fixed soundness bug with lowlevel number functions such as 

1333 
"Abs_Integ" and "Rep_Integ". 

1334 
 Removed "std" option. 

1335 
 Renamed "show_datatypes" to "show_types" and "hide_datatypes" to 

1336 
"hide_types". 

1337 

1338 
* Metis: Removed legacy proof method 'metisFT'. Use 'metis 

1339 
(full_types)' instead. INCOMPATIBILITY. 

1340 

1341 
* Try0: Added 'algebra' and 'meson' to the set of proof methods. 

1342 

1343 
* Adjustion of INF and SUP operations: 

1344 
 Elongated constants INFI and SUPR to INFIMUM and SUPREMUM. 

1345 
 Consolidated theorem names containing INFI and SUPR: have INF and 

1346 
SUP instead uniformly. 

1347 
 More aggressive normalization of expressions involving INF and Inf 

1348 
or SUP and Sup. 

1349 
 INF_image and SUP_image do not unfold composition. 

1350 
 Dropped facts INF_comp, SUP_comp. 

1351 
 Default congruence rules strong_INF_cong and strong_SUP_cong, with 

1352 
simplifier implication in premises. Generalize and replace former 

1353 
INT_cong, SUP_cong 

1354 

1355 
INCOMPATIBILITY. 

1356 

1357 
* SUP and INF generalized to conditionally_complete_lattice. 

1358 

1359

1360 

1361 
image_compose ~> image_comp [symmetric] 

1362 
image_comp ~> image_comp [symmetric] 

1363 
vimage_compose ~> vimage_comp [symmetric]

vimage_comp ~> vimage_comp [symmetric] 

1365 

1366 
INCOMPATIBILITY. 

1367 

57504  1368

1369 
Groups_Big.thy and Lattices_Big.thy. 

55098  1370
