* Better resource usage on all platforms (Linux, Windows, Mac OS X) for 
48 
both Isabelle/ML and Isabelle/Scala. Slightly reduced heap space usage. 

49 

62017  50 
* Former "xsymbols" syntax with Isabelle symbols is used by default, 
51 
without any special print mode. Important ASCII replacement syntax 

52 
remains available under print mode "ASCII", but less important syntax 

53 
has been removed (see below). 

54 

62109  55 
* Support for more arrow symbols, with rendering in LaTeX and Isabelle 
56 
fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>.

* Syntax for formal comments " text" now also supports the symbolic 
69 
form "\<comment> text". Commandline tool "isabelle update_cartouches c" helps 

70 
to update old sources. 

71 

61337  72 
* Toplevel theorem statements have been simplified as follows: 
73 

74 
theorems ~> lemmas 

75 
schematic_lemma ~> schematic_goal 

76 
schematic_theorem ~> schematic_goal 

77 
schematic_corollary ~> schematic_goal 

78 

79 
Commandline tool "isabelle update_theorems" updates theory sources 

80 
accordingly. 

81 

61338  82 
* Toplevel theorem statement 'proposition' is another alias for 
83 
'theorem'. 

84 

62169  85 
* The old 'defs' command has been removed (legacy since Isabelle2014). 
86 
INCOMPATIBILITY, use regular 'definition' instead. Overloaded and/or 

87 
deferred definitions require a surrounding 'overloading' block.

91 

60986  92 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
62253  93 
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands 
94 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

95 
'SML_file_no_debug' control compilation of sources with or without 

96 
debugging information. The Debugger panel allows to set breakpoints (via 

97 
context menu), step through stopped threads, evaluate local ML 

98 
expressions etc. At least one Debugger view needs to be active to have 

99 
any effect on the running ML program. 

60984  100 

61803  101 
* The State panel manages explicit proof state output, with dynamic 
102 
autoupdate according to cursor movement. Alternatively, the jEdit 

103 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

104 
update. 

61729  105 

106 
* The Output panel no longer shows proof state output by default, to 

107 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

108 
enable option "editor_output_state". 

61215  109 

61803  110 
* The text overview column (status of errors, warnings etc.) is updated 
111 
asynchronously, leading to much better editor reactivity. Moreover, the 

112 
full document node content is taken into account. The width of the 

113 
column is scaled according to the main text area font, for improved 

114 
visibility. 

115 

116 
* The main text area no longer changes its color hue in outdated 

117 
situations. The text overview column takes over the role to indicate 

118 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

119 
due to adhoc updates by auxiliary GUI components, such as the State 

120 
panel.

126

127 
implicit: a popup will show up unconditionally. 

128 

129 
* Additional abbreviations for syntactic completion may be specified in 

130 
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with 

131 
support for simple templates using ASCII 007 (bell) as placeholder.

140

*** Document preparation ***

* Commands 'paragraph' and 'subparagraph' provide additional section 
168 
headings. Thus there are 6 levels of standard headings, as in HTML. 

169 

170 
* Command 'text_raw' has been clarified: input text is processed as in 

171 
'text' (with antiquotations and control symbols). The key difference is 

172 
the lack of the surrounding isabelle markup environment in output. 

173 

174 
* Text is structured in paragraphs and nested lists, using notation that 

175 
is similar to Markdown. The control symbols for list items are as

61595  184 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
185 
\<^name> without following cartouche is equivalent to @{name}. The

standard Isabelle fonts provide glyphs to render important control

60449  247

254 

61733  255 
* Assumptions ('assume', 'presume') allow structured rule statements 
256 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  257 

258 
assume result: "C x y" 

259 
if "A x" and "B y" 

260 
for x :: 'a and y :: 'a 

261 

262 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

263 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

264 

265 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

266 
only effects propositions according to actual use of variables. For 

267 
example: 

268 

269 
assume "A x" and "B y" for x and y 

270 

271 
is equivalent to: 

272 

273 
assume "\<And>x. A x" and "\<And>y. B y" 

274 

60595  275 
* The meaning of 'show' with Pure rule statements has changed: premises 
276 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  277 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
278 
follows: 

60595  279 

280 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

281 

282 
or: 

283 

284 
show "C x" if "A x" "B x" for x 

285 

286 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

287 

288 
show "C x" when "A x" "B x" for x 

289 

60459  290 
* New command 'consider' states rules for generalized elimination and 
291 
case splitting. This is like a toplevel statement "theorem obtains" used 

292 
within a proof body; or like a multibranch 'obtain' without activation 

293 
of the local context elements yet. 

294 

60455  295 
* Proof method "cases" allows to specify the rule as first entry of 
296 
chained facts. This is particularly useful with 'consider': 

297 

298 
consider (a) A  (b) B  (c) C <proof> 

299 
then have something 

300 
proof cases 

301 
case a 

302 
then show ?thesis <proof> 

303 
next 

304 
case b 

305 
then show ?thesis <proof> 

306

307 
case c 

308 
then show ?thesis <proof> 

309 
qed 

310 

60565  311 
* Command 'case' allows fact name and attribute specification like this: 
312 

313 
case a: (c xs) 

314 
case a [attributes]: (c xs) 

315 

316 
Facts that are introduced by invoking the case context are uniformly 

317 
qualified by "a"; the same name is used for the cumulative fact. The old 

318 
form "case (c xs) [attributes]" is no longer supported. Rare 

319 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

320 
and always put attributes in front.

328 
the initial backwards refinement is retained for the whole proof, within 

329 
all its context sections (as indicated via 'next'). This is e.g. 

330 
relevant for 'using', 'including', 'supply':

342 

343 
* Improved typeinference for theorem statement 'obtains': separate 

344

345 

346 
* Term abbreviations via 'is' patterns also work for schematic 

347 
statements: result is abstracted over unknowns. 

348 

60631  349 
* Command 'subgoal' allows to impose some structure on backward 
350 
refinements, to avoid proof scripts degenerating into long of 'apply' 

351 
sequences. Further explanations and examples are given in the isarref 

352 
manual.

454

457 
* Qualification of various formal entities in the libraries is done more 

458

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

494 
removed: in LaTeX document output it looks the same as "::". 

495 
INCOMPATIBILITY, use plain "::" instead. 

496 

497 
* Commands 'inductive' and 'inductive_set' work better when names for 

498 
intro rules are omitted: the "cases" and "induct" rules no longer 

499 
declare empty case_names, but no case_names at all. This allows to use 

500 
numbered cases in proofs, without requiring method "goal_cases". 

501 

502 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

503 
lowlevel facts of the internal construction only if the option 

62093  504 
"inductive_internals" is enabled. This refers to the internal predicate

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

567 
'real' is no longer overloaded, but has type 'nat => real' and 

568 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

569 
abbreviates of_int for that type. Other overloaded instances of 'real' 

570

* Pretty printing of Poly/ML compiler output in Isabelle has been 
779 
improved: proper treatment of break offsets and blocks with consistent 

780

* Command 'experiment' opens an anonymous locale context with private 
901

902 

59951  903 
* Command 'notepad' requires proper nesting of begin/end and its proof

structure in the body: 'oops' is no longer supported here. Minor 

905 
INCOMPATIBILITY, use 'sorry' instead. 

906 

907 
* Command 'named_theorems' declares a dynamic fact within the context, 

908 
together with an attribute to maintain the content incrementally. This 

909 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

910 
of semantics due to external visual order vs. internal reverse order.

*** Document preparation *** 
971 

972 
* Document markup commands 'chapter', 'section', 'subsection', 

973 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

974 
context, even before the initial 'theory' command. Obsolete proof 

975 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

976 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

977 
instead. The old 'header' command is still retained for some time, but 

978 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

979 
update_header"). Minor INCOMPATIBILITY. 

980 

60009  981 
* Official support for "tt" style variants, via \isatt{...} or 
982 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

983 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

984 
as argument to other macros (such as footnotes). 

985 

986 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

987 
style. 

988 

989 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

990 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

991 

59951  992 
* Diagnostic commands and document markup commands within a proof do not 
993 
affect the command tag for output. Thus commands like 'thm' are subject 

994 
to proof document structure, and no longer "stick out" accidentally. 

995 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

996 
tags. Potential INCOMPATIBILITY in exotic situations. 

997 

998 
* System option "pretty_margin" is superseded by "thy_output_margin", 

999 
which is also accessible via document antiquotation option "margin". 

1000 
Only the margin for document output may be changed, but not the global 

1001 
pretty printing: that is 76 for plain console output, and adapted 

1002 
dynamically in GUI frontends. Implementations of document 

1003 
antiquotations need to observe the margin explicitly according to 

1004 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

1187 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1188 
constraint, and the combination "real (fact k)" is likely to be 

1189 
unsatisfactory. If a type conversion is still necessary, then use 

1190 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1191 

1192 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1193 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1194 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1195 
"nat_floor"/"nat_ceiling". 

1196 

1197

1200 
field_inverse_zero ~> inverse_zero

1206 
mult_less_imp_less_right ~> mult_right_less_imp_less

1211 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

1212 

1213

60009  1296 
* Subtle change of name space policy: undeclared entries are now 
1297 
considered inaccessible, instead of accessible via the fullyqualified 

1298 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1299 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1300 
contemporary applications use the strict Name_Space.check (and 
60009  1301 
derivatives) instead, which is not affected by the change. Potential 
1302 
INCOMPATIBILITY in rare applications of Name_Space.intern. 

59951  1303

* Basic combinators map, fold, fold_map, split_list, apply are available 
1308

1311 
INCOMPATIBILITY.

Multithreading.synchronized and its highlevel derivative 

1316 
Synchronized.var (which is usually sufficient in applications). Subtle 

1317 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

1318 
nested. 

1319 

60009  1320

* Standard tactics and proof methods such as "clarsimp", "auto" and 
1390 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1391 
variable. Locale assumptions and chained facts containing "x" 

1392 
continue to be useful. The new method "hypsubst_thin" and the 

1393 
configuration option "hypsubst_thin" (within the attribute name space) 

1394 
restore the previous behavior. INCOMPATIBILITY, especially where 

1395 
induction is done after these methods or when the names of free and 

1396 
bound variables clash. As first approximation, old proofs may be 

1397 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1398 

56232  1399 
* More static checking of proof methods, which allows the system to 
1400 
form a closure over the concrete syntax. Method arguments should be 

1401 
processed in the original proof context as far as possible, before 

1402 
operating on the goal state. In any case, the standard discipline for 

1403 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1404 
number that is out of range produces an empty result sequence, not an
