*** General *** 
11 

62017  12 
* Former "xsymbols" syntax with Isabelle symbols is used by default, 
13 
without any special print mode. Important ASCII replacement syntax 

14 
remains available under print mode "ASCII", but less important syntax 

15 
has been removed (see below). 

16 

62109  17 
* Support for more arrow symbols, with rendering in LaTeX and Isabelle 
18 
fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>.

* Syntax for formal comments " text" now also supports the symbolic 
31 
form "\<comment> text". Commandline tool "isabelle update_cartouches c" helps 

32 
to update old sources. 

33 

61337  34 
* Toplevel theorem statements have been simplified as follows: 
35 

36 
theorems ~> lemmas 

37 
schematic_lemma ~> schematic_goal 

38 
schematic_theorem ~> schematic_goal 

39 
schematic_corollary ~> schematic_goal 

40 

41 
Commandline tool "isabelle update_theorems" updates theory sources 

42 
accordingly. 

43 

61338  44 
* Toplevel theorem statement 'proposition' is another alias for 
45 
'theorem'.

49 

60986  50 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  51 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
52 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

53 
'SML_file_no_debug' control compilation of sources with debugging 

54 
information. The Debugger panel allows to set breakpoints (via context 

55 
menu), step through stopped threads, evaluate local ML expressions etc. 

56 
At least one Debugger view needs to be active to have any effect on the 

57 
running ML program. 

58 

61803  59 
* The State panel manages explicit proof state output, with dynamic 
60 
autoupdate according to cursor movement. Alternatively, the jEdit 

61 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

62 
update. 

61729  63 

64 
* The Output panel no longer shows proof state output by default, to 

65 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

66 
enable option "editor_output_state". 

61215  67 

61803  68 
* The text overview column (status of errors, warnings etc.) is updated 
69 
asynchronously, leading to much better editor reactivity. Moreover, the 

70 
full document node content is taken into account. The width of the 

71 
column is scaled according to the main text area font, for improved 

72 
visibility. 

73 

74 
* The main text area no longer changes its color hue in outdated 

75 
situations. The text overview column takes over the role to indicate 

76 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

77 
due to adhoc updates by auxiliary GUI components, such as the State 

78 
panel. 

79 

62017  80 
* Improved scheduling for urgent print tasks (e.g. command state output, 
81 
interactive queries) wrt. longrunning background tasks. 

82 

83 
* Completion of symbols via prefix of \<name> or \<^name> or \name is 

84 
always possible, independently of the language context. It is never 

85 
implicit: a popup will show up unconditionally. 

86 

87 
* Additional abbreviations for syntactic completion may be specified in 

88 
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with 

89 
support for simple templates using ASCII 007 (bell) as placeholder. 

90 

61483  91 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
92 
emphasized text style; the effect is visible in document output, not in 

93 
the editor. 

94 

95 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

96 
instead of former C+e LEFT.

105 
singleinstance applications seen on common GUI desktops.

*** Document preparation *** 
119 

62017  120 
* Commands 'paragraph' and 'subparagraph' provide additional section 
121 
headings. Thus there are 6 levels of standard headings, as in HTML. 

122 

123 
* Command 'text_raw' has been clarified: input text is processed as in 

124 
'text' (with antiquotations and control symbols). The key difference is 

125 
the lack of the surrounding isabelle markup environment in output. 

126 

127 
* Text is structured in paragraphs and nested lists, using notation that 

128 
is similar to Markdown. The control symbols for list items are as 

129 
follows: 

130 

131 
\<^item> itemize 

132 
\<^enum> enumerate 

133 
\<^descr> description

136 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  137 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
138 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  139 
standard Isabelle fonts provide glyphs to render important control 
140 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

61595  142 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
143 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

144 
standard LaTeX macros of the same names.

147 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  148 
text. Commandline tool "isabelle update_cartouches t" helps to update 
149 
old sources, by approximative patching of the content of string and 

150 
cartouche tokens seen in theory sources.

61494  155

156 
or terminal spaces are ignored.

62017  158 
* Antiquotations @{emph} and @{bold} output LaTeX source recursively, 
159 
adding appropriate text style markup. These may be used in the short 

160 
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>. 

161 

162 
* Document antiquotation @{footnote} outputs LaTeX source recursively, 

163 
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>. 

164 

165 
* Antiquotation @{verbatim [display]} supports option "indent". 

166 

167 
* Antiquotation @{theory_text} prints uninterpreted theory source text 

168 
(outer syntax with command keywords etc.). This may be used in the short 

169 
form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent". 

170 

171 
* Antiquotation @{doc ENTRY} provides a reference to the given 

172 
documentation, with a hyperlink in the Prover IDE. 

173 

174 
* Antiquotations @{command}, @{method}, @{attribute} print checked 

175 
entities of the Isar language. 

176 

61471  177 
* HTML presentation uses the standard IsabelleText font and Unicode 
178 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  179 
print mode "HTML" loses its special meaning.

*** Isar *** 
183 

60414  184 
* Local goals ('have', 'show', 'hence', 'thus') allow structured 
61733  185 
rule statements like fixes/assumes/shows in theorem specifications, but 
186 
the notation is postfix with keywords 'if' (or 'when') and 'for'. For 

60555

have result: "C x y"

if "A x" and "B y" 

191 
for x :: 'a and y :: 'a 

192 
<proof> 

193 

60449  194 
The local assumptions are bound to the name "that". The result is 
195 
exported from context of the statement as usual. The above roughly 

60414  196 
corresponds to a raw proof block like this: 
197 

198 
{ 

199 
fix x :: 'a and y :: 'a 

60449  200 
assume that: "A x" "B y" 
60414  201 
have "C x y" <proof>

203

207 

61733  208 
* Assumptions ('assume', 'presume') allow structured rule statements 
209 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  210 

211 
assume result: "C x y" 

212 
if "A x" and "B y" 

213 
for x :: 'a and y :: 'a 

214 

215 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

216 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

217 

218 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

219 
only effects propositions according to actual use of variables. For 

220 
example: 

221 

222 
assume "A x" and "B y" for x and y 

223 

224 
is equivalent to: 

225 

226 
assume "\<And>x. A x" and "\<And>y. B y" 

227 

60595  228 
* The meaning of 'show' with Pure rule statements has changed: premises 
229 
are treated in the sense of 'assume', instead of 'presume'. This means, 

230 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

231 

232 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

233 

234 
or: 

235 

236 
show "C x" if "A x" "B x" for x 

237 

238 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

239 

240 
show "C x" when "A x" "B x" for x 

241 

60459  242 
* New command 'consider' states rules for generalized elimination and 
243 
case splitting. This is like a toplevel statement "theorem obtains" used 

244 
within a proof body; or like a multibranch 'obtain' without activation 

245 
of the local context elements yet. 

246 

60455  247 
* Proof method "cases" allows to specify the rule as first entry of 
248 
chained facts. This is particularly useful with 'consider': 

249 

250 
consider (a) A  (b) B  (c) C <proof> 

251 
then have something 

252 
proof cases 

253 
case a 

254 
then show ?thesis <proof> 

255 
next 

256 
case b 

257 
then show ?thesis <proof> 

258 
next 

259 
case c 

260 
then show ?thesis <proof> 

261 
qed 

262 

60565  263 
* Command 'case' allows fact name and attribute specification like this: 
264 

265 
case a: (c xs) 

266 
case a [attributes]: (c xs) 

267 

268 
Facts that are introduced by invoking the case context are uniformly 

269 
qualified by "a"; the same name is used for the cumulative fact. The old 

270 
form "case (c xs) [attributes]" is no longer supported. Rare 

271 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

272 
and always put attributes in front.

62017  279 
* Nesting of Isar goal structure has been clarified: the context after 
280 
the initial backwards refinement is retained for the whole proof, within 

281 
all its context sections (as indicated via 'next'). This is e.g. 

282 
relevant for 'using', 'including', 'supply': 

283 

284

293 
proof body as well, abstracted over relevant parameters. 

294 

295 
* Improved typeinference for theorem statement 'obtains': separate 

296 
parameter scope for of each clause.

'abbreviation' is also kept for morphims that only change the involved

* The 'typedef' command has been upgraded from a partially checked 
403 
"axiomatization", to a full definitional specification that takes the 

404 
global collection of overloaded constant / type definitions into 

405 
account. Type definitions with open dependencies on overloaded 

406 
definitions need to be specified as "typedef (overloaded)". This 

407 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

408 

409 
* Qualification of various formal entities in the libraries is done more 

410 
uniformly via "context begin qualified definition ... end" instead of 

411 
oldstyle "hide_const (open) ...". Consequently, both the defined 

412 
constant and its defining fact become qualified, e.g. Option.is_none and 

413 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

414 

415 
* Some old and rarely used ASCII replacement syntax has been removed. 

416 
INCOMPATIBILITY, standard syntax with symbols should be used instead.

443

444 

445 
* The alternative notation "\<Colon>" for type and sort constraints has been 

446 
removed: in LaTeX document output it looks the same as "::". 

447 
INCOMPATIBILITY, use plain "::" instead. 

448 

449 
* Commands 'inductive' and 'inductive_set' work better when names for 

450 
intro rules are omitted: the "cases" and "induct" rules no longer 

451 
declare empty case_names, but no case_names at all. This allows to use 

452 
numbered cases in proofs, without requiring method "goal_cases". 

453 

454 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

455 
lowlevel facts of the internal construction only if the option 

62093  456 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  457 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
458 

459 
* Recursive function definitions ('fun', 'function', 'partial_function') 

460 
expose lowlevel facts of the internal construction only if the option 

62093  461 
"function_internals" is enabled. Rare INCOMPATIBILITY. 
462 

463 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

464 
of the internal construction only if the option "bnf_internals" is 

465 
enabled. This supersedes the former option "bnf_note_all". Rare 

466 
INCOMPATIBILITY.

* Combinator to represent case distinction on products is named 

469 
"case_prod", uniformly, discontinuing any input aliasses. Very popular

846 
together with an attribute to maintain the content incrementally. This 

847

*** Document preparation ***

910 
* Document markup commands 'chapter', 'section', 'subsection', 

911 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

912 
context, even before the initial 'theory' command. Obsolete proof 

913 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

914 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

915 
instead. The old 'header' command is still retained for some time, but 

916 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

917 
update_header"). Minor INCOMPATIBILITY. 

918 

60009  919 
* Official support for "tt" style variants, via \isatt{...} or 
920 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

921 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

922 
as argument to other macros (such as footnotes). 

923 

924 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

925 
style. 

926 

927 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

928 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

929 

59951  930 
* Diagnostic commands and document markup commands within a proof do not 
931 
affect the command tag for output. Thus commands like 'thm' are subject 

932 
to proof document structure, and no longer "stick out" accidentally. 

933 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

934 
tags. Potential INCOMPATIBILITY in exotic situations. 

935 

936 
* System option "pretty_margin" is superseded by "thy_output_margin", 

937 
which is also accessible via document antiquotation option "margin". 

938 
Only the margin for document output may be changed, but not the global 

939 
pretty printing: that is 76 for plain console output, and adapted 

940 
dynamically in GUI frontends. Implementations of document 

941 
antiquotations need to observe the margin explicitly according to 

942 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

1008 
INCOMPATIBILITY. 

1009 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  1010 
attribute. This can influence the behavior of the "cases" proof 
1011 
method when more than one case rule is applicable (e.g., an 

1012 
assumption is of the form "w : set ws" and the method "cases w" 

1013 
is invoked). The solution is to specify the case rule explicitly 

1014

1028 
rel_sum (using inductive).

58067  1068 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  1069 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1070 
until applications have been ported to use the new 'smt' method. For 

1071 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1072 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1073 
point to it. 

58062  1074 
INCOMPATIBILITY. 
58067  1075

 New option 'smt_reconstruction_step_timeout' to limit the 
1078 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  1079 
 New option 'smt_statistics' to display statistics of the new 'smt' 
1080 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  1081 

60261  1082 
* Lifting: command 'lift_definition' allows to execute lifted constants 
1083 
that have as a return type a datatype containing a subtype. This 

1084 
overcomes longtime limitations in the area of code generation and 

1085 
lifting, and avoids tedious workarounds. 

60258  1086 

60009  1087 
* Command and antiquotation "value" provide different evaluation slots 
1088 
(again), where the previous strategy (NBE after ML) serves as default. 

1089 
Minor INCOMPATIBILITY. 

1090 

1091 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

1092 

1093 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

1094 
nontermination in case of distributing a division. With this change 

1095 
field_simps is in some cases slightly less powerful, if it fails try to 

1096 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

1097 

1098 
* Separate class no_zero_divisors has been given up in favour of fully 

1099 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.

1121 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

1122 

1123 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1124 
that admits numeric types including nat, int, real and complex. 

1125 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1126 
constraint, and the combination "real (fact k)" is likely to be 

1127 
unsatisfactory. If a type conversion is still necessary, then use 

1128 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1129 

1130 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1131 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1132 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1133 
"nat_floor"/"nat_ceiling". 

1134

mult_less_imp_less_right ~> mult_right_less_imp_less 

1145 
mult_less_imp_less_left ~> mult_left_less_imp_less 

1146 
Minor INCOMPATIBILITY. 

1147 

1148 
* Fact consolidation: even_less_0_iff is subsumed by 

1149 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

1150

60009  1234 
* Subtle change of name space policy: undeclared entries are now 
1235 
considered inaccessible, instead of accessible via the fullyqualified 

1236 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1237 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1238 
contemporary applications use the strict Name_Space.check (and 
60009  1239 
derivatives) instead, which is not affected by the change. Potential 
1240 
INCOMPATIBILITY in rare applications of Name_Space.intern.

* Basic combinators map, fold, fold_map, split_list, apply are available 
1246

* Renamed "pairself" to "apply2", in accordance to @{apply 2}. 

1249 
INCOMPATIBILITY. 

1250 

1251 
* Former combinators NAMED_CRITICAL and CRITICAL for central critical 

1252 
sections have been discontinued, in favour of the more elementary 

1253 
Multithreading.synchronized and its highlevel derivative 

1254 
Synchronized.var (which is usually sufficient in applications). Subtle 

1255 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

1256 
nested. 

1257 

60009  1258 
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle 
1259 
change of semantics with minimal potential for INCOMPATIBILITY.

* Support for official Standard ML within the Isabelle context. 
1319 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1320 
Toplevel bindings are stored within the theory context; the initial 

1321 
environment is restricted to the Standard ML implementation of 

1322 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1323 
and 'SML_export' allow to exchange toplevel bindings between the two 

1324 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1325

1326 

57504  1327 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1328 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1329 
variable. Locale assumptions and chained facts containing "x" 

1330 
continue to be useful. The new method "hypsubst_thin" and the 

1331 
configuration option "hypsubst_thin" (within the attribute name space) 

1332 
restore the previous behavior. INCOMPATIBILITY, especially where 

1333 
induction is done after these methods or when the names of free and 

1334 
bound variables clash. As first approximation, old proofs may be 

1335 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1336 

56232  1337 
* More static checking of proof methods, which allows the system to 
1338 
form a closure over the concrete syntax. Method arguments should be 

1339 
processed in the original proof context as far as possible, before 

1340 
operating on the goal state. In any case, the standard discipline for 

1341 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1342 
number that is out of range produces an empty result sequence, not an 

1343 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1344 
proof tools. 

1345 

57452  1346 
* Lexical syntax (inner and outer) supports text cartouches with 
1347 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1348 
supports input via ` (backquote). 

1349 

1350 
* The outer syntax categories "text" (for formal comments and document 

1351 
markup commands) and "altstring" (for literal fact references) allow 

1352 
cartouches as well, in addition to the traditional mix of quotations. 

1353 

1354 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1355 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1356 
string token. General renovation of its syntax using text cartouches. 
57452  1357 
Minor INCOMPATIBILITY. 
1358 

1359 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1360 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1361 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1362 
INCOMPATIBILITY. 

1363 

1364 
* Document antiquotation @{url} produces markup for the given URL, 

1365 
which results in an active hyperlink within the text. 

1366 

1367 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1368 
not check existence within the filesystem. 

1369 

1370

1371 
isarref, jedit, system.
