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'. 

55 

62169  56 
* The old 'defs' command has been removed (legacy since Isabelle2014). 
57 
INCOMPATIBILITY, use regular 'definition' instead. Overloaded and/or 

58 
deferred definitions require a surrounding 'overloading' block.

62 

60986  63 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  64 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
65 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

66 
'SML_file_no_debug' control compilation of sources with debugging 

67 
information. The Debugger panel allows to set breakpoints (via context 

68 
menu), step through stopped threads, evaluate local ML expressions etc. 

69 
At least one Debugger view needs to be active to have any effect on the 

70 
running ML program. 

71 

61803  72 
* The State panel manages explicit proof state output, with dynamic 
73 
autoupdate according to cursor movement. Alternatively, the jEdit 

74 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

75 
update. 

61729  76 

77 
* The Output panel no longer shows proof state output by default, to 

78 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

79 
enable option "editor_output_state". 

61215  80 

61803  81 
* The text overview column (status of errors, warnings etc.) is updated 
82 
asynchronously, leading to much better editor reactivity. Moreover, the 

83 
full document node content is taken into account. The width of the 

84 
column is scaled according to the main text area font, for improved 

85 
visibility. 

86 

87 
* The main text area no longer changes its color hue in outdated 

88 
situations. The text overview column takes over the role to indicate 

89 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

90 
due to adhoc updates by auxiliary GUI components, such as the State 

91 
panel. 

92 

62017  93 
* Improved scheduling for urgent print tasks (e.g. command state output, 
94 
interactive queries) wrt. longrunning background tasks. 

95 

96 
* Completion of symbols via prefix of \<name> or \<^name> or \name is 

97 
always possible, independently of the language context. It is never 

98 
implicit: a popup will show up unconditionally. 

99 

100 
* Additional abbreviations for syntactic completion may be specified in 

101 
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with 

102 
support for simple templates using ASCII 007 (bell) as placeholder. 

103 

61483  104 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
105 
emphasized text style; the effect is visible in document output, not in 

106 
the editor. 

107 

108 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

109 
instead of former C+e LEFT.

*** Document preparation *** 
132 

62017  133 
* Commands 'paragraph' and 'subparagraph' provide additional section 
134 
headings. Thus there are 6 levels of standard headings, as in HTML. 

135 

136 
* Command 'text_raw' has been clarified: input text is processed as in 

137 
'text' (with antiquotations and control symbols). The key difference is 

138 
the lack of the surrounding isabelle markup environment in output. 

139 

140 
* Text is structured in paragraphs and nested lists, using notation that 

141 
is similar to Markdown. The control symbols for list items are as 

142 
follows: 

143 

144 
\<^item> itemize 

145 
\<^enum> enumerate 

146 
\<^descr> description

149 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  150 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
151 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  152 
standard Isabelle fonts provide glyphs to render important control 
153 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

61595  155 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
156 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

157 
standard LaTeX macros of the same names.

160 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  161

162 
old sources, by approximative patching of the content of string and 

163 
cartouche tokens seen in theory sources.

62017  171 
* Antiquotations @{emph} and @{bold} output LaTeX source recursively, 
172 
adding appropriate text style markup. These may be used in the short 

173 
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>. 

174 

175 
* Document antiquotation @{footnote} outputs LaTeX source recursively, 

176 
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>. 

177 

178 
* Antiquotation @{verbatim [display]} supports option "indent". 

179 

180 
* Antiquotation @{theory_text} prints uninterpreted theory source text 

181 
(outer syntax with command keywords etc.). This may be used in the short 

182 
form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent". 

183 

184 
* Antiquotation @{doc ENTRY} provides a reference to the given 

185 
documentation, with a hyperlink in the Prover IDE. 

186 

187 
* Antiquotations @{command}, @{method}, @{attribute} print checked 

188 
entities of the Isar language. 

189 

61471  190 
* HTML presentation uses the standard IsabelleText font and Unicode 
191 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  192 
print mode "HTML" loses its special meaning.

* Local goals ('have', 'show', 'hence', 'thus') allow structured rule 
198 
statements like fixes/assumes/shows in theorem specifications, but the 

199 
notation is postfix with keywords 'if' (or 'when') and 'for'. For

have result: "C x y"

204 
for x :: 'a and y :: 'a 

205 
<proof> 

206 

60449  207 
The local assumptions are bound to the name "that". The result is 
208 
exported from context of the statement as usual. The above roughly 

60414  209 
corresponds to a raw proof block like this: 
210 

211 
{ 

212 
fix x :: 'a and y :: 'a 

60449  213 
assume that: "A x" "B y"

220 

61733  221 
* Assumptions ('assume', 'presume') allow structured rule statements 
222 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  223 

224 
assume result: "C x y" 

225 
if "A x" and "B y" 

226 
for x :: 'a and y :: 'a 

227 

228 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

229 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

230 

231 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

232 
only effects propositions according to actual use of variables. For 

233 
example: 

234 

235 
assume "A x" and "B y" for x and y 

236 

237 
is equivalent to: 

238 

239 
assume "\<And>x. A x" and "\<And>y. B y" 

240 

60595  241 
* The meaning of 'show' with Pure rule statements has changed: premises 
242 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  243 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
244 
follows: 

60595  245 

246 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

247 

248 
or: 

249 

250 
show "C x" if "A x" "B x" for x 

251 

252 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

253 

254 
show "C x" when "A x" "B x" for x 

255 

60459  256 
* New command 'consider' states rules for generalized elimination and 
257 
case splitting. This is like a toplevel statement "theorem obtains" used 

258 
within a proof body; or like a multibranch 'obtain' without activation 

259 
of the local context elements yet. 

260 

60455  261 
* Proof method "cases" allows to specify the rule as first entry of 
262 
chained facts. This is particularly useful with 'consider': 

263 

264 
consider (a) A  (b) B  (c) C <proof> 

265 
then have something 

266 
proof cases 

267 
case a 

268 
then show ?thesis <proof> 

269 
next 

270 
case b 

271 
then show ?thesis <proof> 

272 
next 

273 
case c 

274 
then show ?thesis <proof> 

275 
qed 

276 

60565  277 
* Command 'case' allows fact name and attribute specification like this: 
278 

279 
case a: (c xs) 

280 
case a [attributes]: (c xs) 

281 

282 
Facts that are introduced by invoking the case context are uniformly 

283 
qualified by "a"; the same name is used for the cumulative fact. The old 

284 
form "case (c xs) [attributes]" is no longer supported. Rare 

285 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

286 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after 
294 
the initial backwards refinement is retained for the whole proof, within 

295 
all its context sections (as indicated via 'next'). This is e.g. 

296 
relevant for 'using', 'including', 'supply':

309 
* Improved typeinference for theorem statement 'obtains': separate 

310 
parameter scope for of each clause. 

311 

312 
* Term abbreviations via 'is' patterns also work for schematic 

313 
statements: result is abstracted over unknowns. 

314 

60631  315 
* Command 'subgoal' allows to impose some structure on backward 
316 
refinements, to avoid proof scripts degenerating into long of 'apply' 

317 
sequences. Further explanations and examples are given in the isarref 

318 
manual.

60617  348 
is marked as legacy, and will be removed eventually. The proof method 
349 
"goals" achieves a similar effect within regular Isar; often it can be

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

374 
when working with complex locale hierarchies, because proof states are

* The 'typedef' command has been upgraded from a partially checked 
417 
"axiomatization", to a full definitional specification that takes the 

418 
global collection of overloaded constant / type definitions into 

419 
account. Type definitions with open dependencies on overloaded 

420 
definitions need to be specified as "typedef (overloaded)". This 

421 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

422 

423 
* Qualification of various formal entities in the libraries is done more 

424 
uniformly via "context begin qualified definition ... end" instead of 

425 
oldstyle "hide_const (open) ...". Consequently, both the defined 

426 
constant and its defining fact become qualified, e.g. Option.is_none and 

427 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

428

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

430 
INCOMPATIBILITY, standard syntax with symbols should be used instead.

457 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

458 

459 
* The alternative notation "\<Colon>" for type and sort constraints has been 

460 
removed: in LaTeX document output it looks the same as "::". 

461 
INCOMPATIBILITY, use plain "::" instead. 

462 

463 
* Commands 'inductive' and 'inductive_set' work better when names for 

464 
intro rules are omitted: the "cases" and "induct" rules no longer 

465 
declare empty case_names, but no case_names at all. This allows to use 

466 
numbered cases in proofs, without requiring method "goal_cases". 

467 

468 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

469 
lowlevel facts of the internal construction only if the option 

62093  470 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  471 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
472 

473 
* Recursive function definitions ('fun', 'function', 'partial_function') 

474 
expose lowlevel facts of the internal construction only if the option 

62205  475 
"function_internals" is enabled. Its internal inductive definition is 
476 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  477 

478 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

479 
of the internal construction only if the option "bnf_internals" is 

480 
enabled. This supersedes the former option "bnf_note_all". Rare 

481 
INCOMPATIBILITY. 

62017  482 

483 
* Combinator to represent case distinction on products is named 

484 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

485 
theorem aliasses have been retained.

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

533 
'real' is no longer overloaded, but has type 'nat => real' and 

534 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

535 
abbreviates of_int for that type. Other overloaded instances of 'real' 

536 
have been replaced by 'real_of_ereal' and 'real_of_float'.

*** ML ***

62017  723 
* The following combinators for lowlevel profiling of the ML runtime 
724 
system are available: 

725 

726 
profile_time (*CPU time*) 

727 
profile_time_thread (*CPU time on this thread*) 

728 
profile_allocations (*overall heap allocations*) 

729 

730 
* Antiquotation @{undefined} or \<^undefined> inlines (raise Match). 

731 

62075  732 
* Antiquotation @{method NAME} inlines the (checked) name of the given 
733 
Isar proof method. 

734 

61922  735 
* Pretty printing of Poly/ML compiler output in Isabelle has been 
736 
improved: proper treatment of break offsets and blocks with consistent 

737 
breaks. 

738 

61268  739 
* The auxiliary module Pure/display.ML has been eliminated. Its 
740 
elementary thm print operations are now in Pure/more_thm.ML and thus 

741 
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY. 

742 

61144  743 
* Simproc programming interfaces have been simplified: 
744 
Simplifier.make_simproc and Simplifier.define_simproc supersede various 

745 
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that 

746 
term patterns for the lefthand sides are specified with implicitly 

747 
fixed variables, like toplevel theorem statements. INCOMPATIBILITY. 

748 

60802  749 
* Instantiation rules have been reorganized as follows: 
750 

751 
Thm.instantiate (*lowlevel instantiation with named arguments*) 

752 
Thm.instantiate' (*version with positional arguments*) 

753 

754 
Drule.infer_instantiate (*instantiation with type inference*) 

755 
Drule.infer_instantiate' (*version with positional arguments*) 

756 

757 
The LHS only requires variable specifications, instead of full terms. 

758 
Old cterm_instantiate is superseded by infer_instantiate. 

759 
INCOMPATIBILITY, need to readjust some ML names and types accordingly. 

760 

60793  761 
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been 
762 
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc. 

763 
instead (with proper context).

865 
together with an attribute to maintain the content incrementally. This 

866 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
928 

929 
* Document markup commands 'chapter', 'section', 'subsection', 

930 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

931 
context, even before the initial 'theory' command. Obsolete proof 

932 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

933 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

934 
instead. The old 'header' command is still retained for some time, but 

935 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

936 
update_header"). Minor INCOMPATIBILITY. 

937 

60009  938 
* Official support for "tt" style variants, via \isatt{...} or 
939 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

940 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

941 
as argument to other macros (such as footnotes). 

942 

943 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

944 
style. 

945 

946 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

947 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

948 

59951  949 
* Diagnostic commands and document markup commands within a proof do not 
950 
affect the command tag for output. Thus commands like 'thm' are subject 

951 
to proof document structure, and no longer "stick out" accidentally. 

952 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

953 
tags. Potential INCOMPATIBILITY in exotic situations. 

954 

955 
* System option "pretty_margin" is superseded by "thy_output_margin", 

956 
which is also accessible via document antiquotation option "margin". 

957 
Only the margin for document output may be changed, but not the global 

958

60009  1256 
* Subtle change of name space policy: undeclared entries are now 
1257 
considered inaccessible, instead of accessible via the fullyqualified 

1258 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1259 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1260 
contemporary applications use the strict Name_Space.check (and 
60009  1261 
derivatives) instead, which is not affected by the change. Potential

INCOMPATIBILITY in rare applications of Name_Space.intern.

Multithreading.synchronized and its highlevel derivative 

1276 
Synchronized.var (which is usually sufficient in applications). Subtle 

1277 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

1278 
nested. 

1279

* Support for official Standard ML within the Isabelle context. 
1341 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1342 
Toplevel bindings are stored within the theory context; the initial 

1343 
environment is restricted to the Standard ML implementation of 

1344 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1345 
and 'SML_export' allow to exchange toplevel bindings between the two 

1346 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1347

1348 

57504  1349 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1350 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1351 
variable. Locale assumptions and chained facts containing "x" 

1352 
continue to be useful. The new method "hypsubst_thin" and the 

1353 
configuration option "hypsubst_thin" (within the attribute name space) 

1354 
restore the previous behavior. INCOMPATIBILITY, especially where 

1355 
induction is done after these methods or when the names of free and 

1356 
bound variables clash. As first approximation, old proofs may be 

1357 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1358 

56232  1359 
* More static checking of proof methods, which allows the system to 
1360 
form a closure over the concrete syntax. Method arguments should be 

1361 
processed in the original proof context as far as possible, before 

1362 
operating on the goal state. In any case, the standard discipline for 

1363 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1364 
number that is out of range produces an empty result sequence, not an 

1365 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1366 
proof tools. 

1367 

57452  1368 
* Lexical syntax (inner and outer) supports text cartouches with 
1369 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1370 
supports input via ` (backquote). 

1371 

1372 
* The outer syntax categories "text" (for formal comments and document 

1373 
markup commands) and "altstring" (for literal fact references) allow 

1374 
cartouches as well, in addition to the traditional mix of quotations. 

1375 

1376 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1377 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1378 
string token. General renovation of its syntax using text cartouches. 
57452  1379 
Minor INCOMPATIBILITY. 
1380 

1381 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1382 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1383 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1384 
INCOMPATIBILITY. 

1385 

1386 
* Document antiquotation @{url} produces markup for the given URL, 

1387 
which results in an active hyperlink within the text. 

1388 

1389 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1390 
not check existence within the filesystem.
