62157  18 
* Better resource usage on all platforms (Linux, Windows, Mac OS X) for 
19 
both Isabelle/ML and Isabelle/Scala. Slightly reduced heap space usage. 

20 

62017  21 
* Former "xsymbols" syntax with Isabelle symbols is used by default, 
22 
without any special print mode. Important ASCII replacement syntax 

23 
remains available under print mode "ASCII", but less important syntax 

24 
has been removed (see below). 

25 

62109  26 
* Support for more arrow symbols, with rendering in LaTeX and Isabelle 
27 
fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>.

* Syntax for formal comments " text" now also supports the symbolic 
40 
form "\<comment> text". Commandline tool "isabelle update_cartouches c" helps 

41 
to update old sources. 

42 

61337  43 
* Toplevel theorem statements have been simplified as follows: 
44 

45 
theorems ~> lemmas 

46 
schematic_lemma ~> schematic_goal 

47 
schematic_theorem ~> schematic_goal 

48 
schematic_corollary ~> schematic_goal 

49 

50 
Commandline tool "isabelle update_theorems" updates theory sources 

51 
accordingly. 

52 

61338  53 
* Toplevel theorem statement 'proposition' is another alias for 
54 
'theorem'.

58 

60986  59 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  60 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
61 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

62 
'SML_file_no_debug' control compilation of sources with debugging 

63 
information. The Debugger panel allows to set breakpoints (via context 

64 
menu), step through stopped threads, evaluate local ML expressions etc. 

65 
At least one Debugger view needs to be active to have any effect on the 

66 
running ML program. 

67 

61803  68 
* The State panel manages explicit proof state output, with dynamic 
69 
autoupdate according to cursor movement. Alternatively, the jEdit 

70 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

71 
update. 

61729  72 

73 
* The Output panel no longer shows proof state output by default, to 

74 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

75 
enable option "editor_output_state". 

61215  76 

61803  77 
* The text overview column (status of errors, warnings etc.) is updated 
78 
asynchronously, leading to much better editor reactivity. Moreover, the 

79 
full document node content is taken into account. The width of the 

80 
column is scaled according to the main text area font, for improved 

81 
visibility. 

82 

83 
* The main text area no longer changes its color hue in outdated 

84 
situations. The text overview column takes over the role to indicate 

85 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

86 
due to adhoc updates by auxiliary GUI components, such as the State 

87 
panel. 

88 

62017  89 
* Improved scheduling for urgent print tasks (e.g. command state output, 
90 
interactive queries) wrt. longrunning background tasks. 

91 

92 
* Completion of symbols via prefix of \<name> or \<^name> or \name is 

93 
always possible, independently of the language context. It is never 

94 
implicit: a popup will show up unconditionally. 

95 

96 
* Additional abbreviations for syntactic completion may be specified in 

97 
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with 

98 
support for simple templates using ASCII 007 (bell) as placeholder. 

99 

61483  100 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
101 
emphasized text style; the effect is visible in document output, not in 

102 
the editor. 

103 

104 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

105 
instead of former C+e LEFT.

*** Document preparation *** 
128 

62017  129 
* Commands 'paragraph' and 'subparagraph' provide additional section 
130 
headings. Thus there are 6 levels of standard headings, as in HTML. 

131 

132 
* Command 'text_raw' has been clarified: input text is processed as in 

133 
'text' (with antiquotations and control symbols). The key difference is 

134 
the lack of the surrounding isabelle markup environment in output. 

135 

136 
* Text is structured in paragraphs and nested lists, using notation that 

137 
is similar to Markdown. The control symbols for list items are as 

138 
follows: 

139 

140 
\<^item> itemize 

141 
\<^enum> enumerate 

142 
\<^descr> description

145 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  146 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
147 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  148 
standard Isabelle fonts provide glyphs to render important control 
149 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

61595  151 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
152 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

153 
standard LaTeX macros of the same names.

156 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  157 
text. Commandline tool "isabelle update_cartouches t" helps to update 
158 
old sources, by approximative patching of the content of string and 

159 
cartouche tokens seen in theory sources.

62017  167 
* Antiquotations @{emph} and @{bold} output LaTeX source recursively, 
168 
adding appropriate text style markup. These may be used in the short 

169 
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>. 

170 

171 
* Document antiquotation @{footnote} outputs LaTeX source recursively, 

172 
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>. 

173 

174 
* Antiquotation @{verbatim [display]} supports option "indent". 

175 

176 
* Antiquotation @{theory_text} prints uninterpreted theory source text 

177 
(outer syntax with command keywords etc.). This may be used in the short 

178 
form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent". 

179 

180 
* Antiquotation @{doc ENTRY} provides a reference to the given 

181 
documentation, with a hyperlink in the Prover IDE. 

182 

183 
* Antiquotations @{command}, @{method}, @{attribute} print checked 

184 
entities of the Isar language. 

185 

61471  186 
* HTML presentation uses the standard IsabelleText font and Unicode 
187 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  188 
print mode "HTML" loses its special meaning.

60414  193 
* Local goals ('have', 'show', 'hence', 'thus') allow structured 
61733  194 
rule statements like fixes/assumes/shows in theorem specifications, but 
195 
the notation is postfix with keywords 'if' (or 'when') and 'for'. For

200 
for x :: 'a and y :: 'a 

201 
<proof> 

202 

60449  203 
The local assumptions are bound to the name "that". The result is 
204 
exported from context of the statement as usual. The above roughly 

60414  205 
corresponds to a raw proof block like this: 
206 

207 
{ 

208 
fix x :: 'a and y :: 'a 

60449  209 
assume that: "A x" "B y"

216 

61733  217 
* Assumptions ('assume', 'presume') allow structured rule statements 
218 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  219 

220 
assume result: "C x y" 

221 
if "A x" and "B y" 

222 
for x :: 'a and y :: 'a 

223 

224 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

225 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

226 

227 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

228 
only effects propositions according to actual use of variables. For 

229 
example: 

230 

231 
assume "A x" and "B y" for x and y 

232 

233 
is equivalent to: 

234 

235 
assume "\<And>x. A x" and "\<And>y. B y" 

236 

60595  237 
* The meaning of 'show' with Pure rule statements has changed: premises 
238 
are treated in the sense of 'assume', instead of 'presume'. This means, 

239 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

240 

241 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

242 

243 
or: 

244 

245 
show "C x" if "A x" "B x" for x 

246 

247 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

248 

249 
show "C x" when "A x" "B x" for x 

250 

60459  251 
* New command 'consider' states rules for generalized elimination and 
252 
case splitting. This is like a toplevel statement "theorem obtains" used 

253 
within a proof body; or like a multibranch 'obtain' without activation 

254 
of the local context elements yet. 

255 

60455  256 
* Proof method "cases" allows to specify the rule as first entry of 
257 
chained facts. This is particularly useful with 'consider': 

258 

259 
consider (a) A  (b) B  (c) C <proof> 

260 
then have something 

261 
proof cases 

262 
case a 

263 
then show ?thesis <proof> 

264 
next 

265 
case b 

266 
then show ?thesis <proof> 

267 
next 

268 
case c 

269 
then show ?thesis <proof> 

270 
qed 

271 

60565  272 
* Command 'case' allows fact name and attribute specification like this: 
273 

274 
case a: (c xs) 

275 
case a [attributes]: (c xs) 

276 

277 
Facts that are introduced by invoking the case context are uniformly 

278 
qualified by "a"; the same name is used for the cumulative fact. The old 

279 
form "case (c xs) [attributes]" is no longer supported. Rare 

280 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

281 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after 
289 
the initial backwards refinement is retained for the whole proof, within 

290 
all its context sections (as indicated via 'next'). This is e.g. 

291 
relevant for 'using', 'including', 'supply': 

292

* Command 'obtain' binds term abbreviations (via 'is' patterns) in the 

302 
proof body as well, abstracted over relevant parameters. 

303 

304 
* Improved typeinference for theorem statement 'obtains': separate 

305 
parameter scope for of each clause. 

306 

307 
* Term abbreviations via 'is' patterns also work for schematic 

308 
statements: result is abstracted over unknowns. 

309 

60631  310 
* Command 'subgoal' allows to impose some structure on backward 
311 
refinements, to avoid proof scripts degenerating into long of 'apply' 

312 
sequences. Further explanations and examples are given in the isarref 

313 
manual.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  343 
is marked as legacy, and will be removed eventually. The proof method 
344 
"goals" achieves a similar effect within regular Isar; often it can be

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

parameters, and only 'notation' is suppressed. This can be of great help 
369 
when working with complex locale hierarchies, because proof states are

* The 'typedef' command has been upgraded from a partially checked 
412 
"axiomatization", to a full definitional specification that takes the 

413 
global collection of overloaded constant / type definitions into 

414 
account. Type definitions with open dependencies on overloaded 

415 
definitions need to be specified as "typedef (overloaded)". This 

416 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

417 

418 
* Qualification of various formal entities in the libraries is done more 

419 
uniformly via "context begin qualified definition ... end" instead of 

420 
oldstyle "hide_const (open) ...". Consequently, both the defined 

421 
constant and its defining fact become qualified, e.g. Option.is_none and 

422 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

423 

424 
* Some old and rarely used ASCII replacement syntax has been removed. 

425 
INCOMPATIBILITY, standard syntax with symbols should be used instead.

452 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

453 

454 
* The alternative notation "\<Colon>" for type and sort constraints has been 

455 
removed: in LaTeX document output it looks the same as "::". 

456 
INCOMPATIBILITY, use plain "::" instead. 

457 

458 
* Commands 'inductive' and 'inductive_set' work better when names for 

459 
intro rules are omitted: the "cases" and "induct" rules no longer 

460 
declare empty case_names, but no case_names at all. This allows to use 

461 
numbered cases in proofs, without requiring method "goal_cases". 

462 

463 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

464 
lowlevel facts of the internal construction only if the option 

62093  465 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  466 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
467 

468 
* Recursive function definitions ('fun', 'function', 'partial_function') 

469 
expose lowlevel facts of the internal construction only if the option 

62093  470 
"function_internals" is enabled. Rare INCOMPATIBILITY. 
471 

472 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

473 
of the internal construction only if the option "bnf_internals" is 

474 
enabled. This supersedes the former option "bnf_note_all". Rare 

475 
INCOMPATIBILITY. 

62017  476 

477 
* Combinator to represent case distinction on products is named 

478 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

479 
theorem aliasses have been retained.

* The coercions to type 'real' have been reorganised. The function 

527 
'real' is no longer overloaded, but has type 'nat => real' and 

528 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

529 
abbreviates of_int for that type. Other overloaded instances of 'real' 

530 
have been replaced by 'real_of_ereal' and 'real_of_float'.

*** ML *** 
716 

62017  717 
* The following combinators for lowlevel profiling of the ML runtime 
718 
system are available: 

719 

720 
profile_time (*CPU time*) 

721 
profile_time_thread (*CPU time on this thread*) 

722 
profile_allocations (*overall heap allocations*) 

723 

724 
* Antiquotation @{undefined} or \<^undefined> inlines (raise Match). 

725 

62075  726 
* Antiquotation @{method NAME} inlines the (checked) name of the given 
727 
Isar proof method. 

728 

61922  729 
* Pretty printing of Poly/ML compiler output in Isabelle has been 
730 
improved: proper treatment of break offsets and blocks with consistent 

731 
breaks. 

732 

61268  733 
* The auxiliary module Pure/display.ML has been eliminated. Its 
734 
elementary thm print operations are now in Pure/more_thm.ML and thus 

735 
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY. 

736 

61144  737 
* Simproc programming interfaces have been simplified: 
738 
Simplifier.make_simproc and Simplifier.define_simproc supersede various 

739 
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that 

740 
term patterns for the lefthand sides are specified with implicitly 

741 
fixed variables, like toplevel theorem statements. INCOMPATIBILITY. 

742 

60802  743 
* Instantiation rules have been reorganized as follows: 
744 

745 
Thm.instantiate (*lowlevel instantiation with named arguments*) 

746 
Thm.instantiate' (*version with positional arguments*) 

747 

748 
Drule.infer_instantiate (*instantiation with type inference*) 

749 
Drule.infer_instantiate' (*version with positional arguments*) 

750 

751 
The LHS only requires variable specifications, instead of full terms. 

752 
Old cterm_instantiate is superseded by infer_instantiate. 

753 
INCOMPATIBILITY, need to readjust some ML names and types accordingly. 

754 

60793  755 
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been 
756 
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc. 

757 
instead (with proper context).

* Command 'experiment' opens an anonymous locale context with private

naming policy. 

853 

59951  854 
* Command 'notepad' requires proper nesting of begin/end and its proof

856 
INCOMPATIBILITY, use 'sorry' instead. 

857 

858 
* Command 'named_theorems' declares a dynamic fact within the context, 

859 
together with an attribute to maintain the content incrementally. This 

860 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

861 
of semantics due to external visual order vs. internal reverse order.

*** Document preparation *** 
922 

923 
* Document markup commands 'chapter', 'section', 'subsection', 

924 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

925 
context, even before the initial 'theory' command. Obsolete proof 

926 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

927 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

928 
instead. The old 'header' command is still retained for some time, but 

929 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

930 
update_header"). Minor INCOMPATIBILITY. 

931 

60009  932 
* Official support for "tt" style variants, via \isatt{...} or 
933 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

934 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

935 
as argument to other macros (such as footnotes). 

936 

937 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

938 
style. 

939 

940 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

941 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

942 

59951  943 
* Diagnostic commands and document markup commands within a proof do not 
944 
affect the command tag for output. Thus commands like 'thm' are subject 

945 
to proof document structure, and no longer "stick out" accidentally. 

946 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

947 
tags. Potential INCOMPATIBILITY in exotic situations. 

948 

949 
* System option "pretty_margin" is superseded by "thy_output_margin", 

950 
which is also accessible via document antiquotation option "margin". 

951 
Only the margin for document output may be changed, but not the global 

952 
pretty printing: that is 76 for plain console output, and adapted 

953 
dynamically in GUI frontends. Implementations of document 

954 
antiquotations need to observe the margin explicitly according to 

955 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

nontermination in case of distributing a division. With this change

60009  1247 
* Subtle change of name space policy: undeclared entries are now 
1248 
considered inaccessible, instead of accessible via the fullyqualified 

1249 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1250 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1251 
contemporary applications use the strict Name_Space.check (and 
60009  1252 
derivatives) instead, which is not affected by the change. Potential 
1253 
INCOMPATIBILITY in rare applications of Name_Space.intern. 

59951  1254 

60094  1255 
* Subtle change of error semantics of Toplevel.proof_of: regular user 
1256 
ERROR instead of internal Toplevel.UNDEF. 

1257 

59951  1258 
* Basic combinators map, fold, fold_map, split_list, apply are available 
1259 
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples. 

1260 

1261 
* Renamed "pairself" to "apply2", in accordance to @{apply 2}. 

1262 
INCOMPATIBILITY. 

1263 

1264 
* Former combinators NAMED_CRITICAL and CRITICAL for central critical 

1265 
sections have been discontinued, in favour of the more elementary 

1266 
Multithreading.synchronized and its highlevel derivative 

1267 
Synchronized.var (which is usually sufficient in applications). Subtle 

1268 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

1269 
nested. 

1270 

60009  1271 
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle 
1272 
change of semantics with minimal potential for INCOMPATIBILITY.

* Support for official Standard ML within the Isabelle context. 
1332 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1333 
Toplevel bindings are stored within the theory context; the initial 

1334 
environment is restricted to the Standard ML implementation of 

1335 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1336 
and 'SML_export' allow to exchange toplevel bindings between the two 

1337 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1338 
some examples.

1339 

57504  1340 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1341 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1342 
variable. Locale assumptions and chained facts containing "x" 

1343 
continue to be useful. The new method "hypsubst_thin" and the 

1344 
configuration option "hypsubst_thin" (within the attribute name space) 

1345 
restore the previous behavior. INCOMPATIBILITY, especially where 

1346 
induction is done after these methods or when the names of free and 

1347 
bound variables clash. As first approximation, old proofs may be 

1348 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1349 

56232  1350 
* More static checking of proof methods, which allows the system to 
1351 
form a closure over the concrete syntax. Method arguments should be 

1352 
processed in the original proof context as far as possible, before 

1353 
operating on the goal state. In any case, the standard discipline for 

1354 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1355 
number that is out of range produces an empty result sequence, not an 

1356 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1357 
proof tools. 

1358 

57452  1359 
* Lexical syntax (inner and outer) supports text cartouches with 
1360 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1361 
supports input via ` (backquote). 

1362 

1363 
* The outer syntax categories "text" (for formal comments and document 

1364 
markup commands) and "altstring" (for literal fact references) allow 

1365 
cartouches as well, in addition to the traditional mix of quotations. 

1366 

1367 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1368 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1369 
string token. General renovation of its syntax using text cartouches. 
57452  1370 
Minor INCOMPATIBILITY. 
1371 

1372 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1373 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1374 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1375 
INCOMPATIBILITY. 

1376 

1377 
* Document antiquotation @{url} produces markup for the given URL, 

1378 
which results in an active hyperlink within the text. 

1379 

1380 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1381 
not check existence within the filesystem. 

1382
