*** 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 

17 
* Support for more arrow symbols, with rendering in LaTeX and 

18 
Isabelle fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow> 

19 

20 
* Syntax for formal comments " text" now also supports the symbolic 

21 
form "\<comment> text". Commandline tool "isabelle update_cartouches c" helps 

22 
to update old sources. 

23 

61337  24 
* Toplevel theorem statements have been simplified as follows: 
25 

26 
theorems ~> lemmas 

27 
schematic_lemma ~> schematic_goal 

28 
schematic_theorem ~> schematic_goal 

29 
schematic_corollary ~> schematic_goal 

30 

31 
Commandline tool "isabelle update_theorems" updates theory sources 

32 
accordingly. 

33 

61338  34 
* Toplevel theorem statement 'proposition' is another alias for 
35 
'theorem'.

39 

60986  40 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  41 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
42 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

43 
'SML_file_no_debug' control compilation of sources with debugging 

44 
information. The Debugger panel allows to set breakpoints (via context 

45 
menu), step through stopped threads, evaluate local ML expressions etc. 

46 
At least one Debugger view needs to be active to have any effect on the 

47 
running ML program. 

48 

61803  49 
* The State panel manages explicit proof state output, with dynamic 
50 
autoupdate according to cursor movement. Alternatively, the jEdit 

51 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

52 
update. 

61729  53 

54 
* The Output panel no longer shows proof state output by default, to 

55 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

56 
enable option "editor_output_state". 

61215  57 

61803  58 
* The text overview column (status of errors, warnings etc.) is updated 
59 
asynchronously, leading to much better editor reactivity. Moreover, the 

60 
full document node content is taken into account. The width of the 

61 
column is scaled according to the main text area font, for improved 

62 
visibility. 

63 

64 
* The main text area no longer changes its color hue in outdated 

65 
situations. The text overview column takes over the role to indicate 

66 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

67 
due to adhoc updates by auxiliary GUI components, such as the State 

68 
panel. 

69 

62017  70 
* Improved scheduling for urgent print tasks (e.g. command state output, 
71 
interactive queries) wrt. longrunning background tasks. 

72 

73 
* Completion of symbols via prefix of \<name> or \<^name> or \name is 

74 
always possible, independently of the language context. It is never 

75 
implicit: a popup will show up unconditionally. 

76 

77 
* Additional abbreviations for syntactic completion may be specified in 

78 
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with 

79 
support for simple templates using ASCII 007 (bell) as placeholder. 

80 

61483  81 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
82 
emphasized text style; the effect is visible in document output, not in 

83 
the editor. 

84 

85 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

86 
instead of former C+e LEFT.

92 

62017  93 
* New commandline tool "isabelle jedit_client" allows to connect to an 
94 
already running Isabelle/jEdit process. This achieves the effect of 

95 
singleinstance applications seen on common GUI desktops. 

96 

97 
* The main Isabelle executable is managed as singleinstance Desktop 

98 
application uniformly on all platforms: Linux, Windows, Mac OS X.

*** Document preparation *** 
106 

62017  107 
* Commands 'paragraph' and 'subparagraph' provide additional section 
108 
headings. Thus there are 6 levels of standard headings, as in HTML. 

109 

110 
* Command 'text_raw' has been clarified: input text is processed as in 

111 
'text' (with antiquotations and control symbols). The key difference is 

112 
the lack of the surrounding isabelle markup environment in output. 

113 

114 
* Text is structured in paragraphs and nested lists, using notation that 

115 
is similar to Markdown. The control symbols for list items are as 

116 
follows: 

117 

118 
\<^item> itemize 

119 
\<^enum> enumerate 

120 
\<^descr> description

123 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  124 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
125 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  126 
standard Isabelle fonts provide glyphs to render important control 
127 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

128 

61595  129 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
130 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

131 
standard LaTeX macros of the same names.

134 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  135 
text. Commandline tool "isabelle update_cartouches t" helps to update 
136 
old sources, by approximative patching of the content of string and 

137 
cartouche tokens seen in theory sources.

61494  142

143 
or terminal spaces are ignored.

62017  145 
* Antiquotations @{emph} and @{bold} output LaTeX source recursively, 
146 
adding appropriate text style markup. These may be used in the short 

147 
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>. 

148 

149 
* Document antiquotation @{footnote} outputs LaTeX source recursively, 

150 
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>. 

151 

152 
* Antiquotation @{verbatim [display]} supports option "indent". 

153 

154 
* Antiquotation @{theory_text} prints uninterpreted theory source text 

155 
(outer syntax with command keywords etc.). This may be used in the short 

156 
form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent". 

157 

158 
* Antiquotation @{doc ENTRY} provides a reference to the given 

159 
documentation, with a hyperlink in the Prover IDE. 

160 

161 
* Antiquotations @{command}, @{method}, @{attribute} print checked 

162 
entities of the Isar language. 

163 

61471  164 
* HTML presentation uses the standard IsabelleText font and Unicode 
165 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  166 
print mode "HTML" loses its special meaning.

60414  171 
* Local goals ('have', 'show', 'hence', 'thus') allow structured 
61733  172 
rule statements like fixes/assumes/shows in theorem specifications, but 
173 
the notation is postfix with keywords 'if' (or 'when') and 'for'. For 

60555

178 
for x :: 'a and y :: 'a 

179 
<proof> 

180 

60449  181 
The local assumptions are bound to the name "that". The result is 
182 
exported from context of the statement as usual. The above roughly 

60414  183 
corresponds to a raw proof block like this: 
184 

185 
{ 

186 
fix x :: 'a and y :: 'a 

60449  187 
assume that: "A x" "B y" 
60414  188 
have "C x y" <proof> 
189 
} 

190

194 

61733  195 
* Assumptions ('assume', 'presume') allow structured rule statements 
196 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  197 

198 
assume result: "C x y" 

199 
if "A x" and "B y" 

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

201 

202 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

203 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

204 

205 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

206 
only effects propositions according to actual use of variables. For 

207 
example: 

208 

209 
assume "A x" and "B y" for x and y 

210 

211 
is equivalent to: 

212 

213 
assume "\<And>x. A x" and "\<And>y. B y" 

214 

60595  215 
* The meaning of 'show' with Pure rule statements has changed: premises 
216 
are treated in the sense of 'assume', instead of 'presume'. This means, 

217 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

218 

219 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

220 

221 
or: 

222 

223 
show "C x" if "A x" "B x" for x 

224 

225 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

226 

227 
show "C x" when "A x" "B x" for x 

228 

60459  229 
* New command 'consider' states rules for generalized elimination and 
230 
case splitting. This is like a toplevel statement "theorem obtains" used 

231 
within a proof body; or like a multibranch 'obtain' without activation 

232 
of the local context elements yet. 

233 

60455  234 
* Proof method "cases" allows to specify the rule as first entry of 
235 
chained facts. This is particularly useful with 'consider': 

236 

237 
consider (a) A  (b) B  (c) C <proof> 

238 
then have something 

239 
proof cases 

240 
case a 

241 
then show ?thesis <proof> 

242 
next 

243 
case b 

244 
then show ?thesis <proof> 

245 
next 

246 
case c 

247 
then show ?thesis <proof> 

248 
qed 

249 

60565  250 
* Command 'case' allows fact name and attribute specification like this: 
251 

252 
case a: (c xs) 

253 
case a [attributes]: (c xs) 

254 

255 
Facts that are introduced by invoking the case context are uniformly 

256 
qualified by "a"; the same name is used for the cumulative fact. The old 

257 
form "case (c xs) [attributes]" is no longer supported. Rare 

258 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

259 
and always put attributes in front.

62017  266 
* Nesting of Isar goal structure has been clarified: the context after 
267 
the initial backwards refinement is retained for the whole proof, within 

268 
all its context sections (as indicated via 'next'). This is e.g. 

269 
relevant for 'using', 'including', 'supply': 

270 

271 
have "A \<and> A" if a: A for A 

272

279 
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the 

280 
proof body as well, abstracted over relevant parameters. 

281 

282 
* Improved typeinference for theorem statement 'obtains': separate 

283 
parameter scope for of each clause. 

284 

285 
* Term abbreviations via 'is' patterns also work for schematic 

286 
statements: result is abstracted over unknowns. 

287 

60631  288 
* Command 'subgoal' allows to impose some structure on backward 
289 
refinements, to avoid proof scripts degenerating into long of 'apply' 

290 
sequences. Further explanations and examples are given in the isarref 

291 
manual. 

292 

62017  293 
* Command 'supply' supports fact definitions during goal refinement

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  321 
is marked as legacy, and will be removed eventually. The proof method 
322 
"goals" achieves a similar effect within regular Isar; often it can be 

323 
done more adequately by other means (e.g. 'consider').

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

347 
when working with complex locale hierarchies, because proof states are

62017  389 
* The 'typedef' command has been upgraded from a partially checked 
390 
"axiomatization", to a full definitional specification that takes the 

391 
global collection of overloaded constant / type definitions into 

392 
account. Type definitions with open dependencies on overloaded 

393 
definitions need to be specified as "typedef (overloaded)". This 

394 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

395 

396 
* Qualification of various formal entities in the libraries is done more 

397 
uniformly via "context begin qualified definition ... end" instead of 

398 
oldstyle "hide_const (open) ...". Consequently, both the defined 

399 
constant and its defining fact become qualified, e.g. Option.is_none and 

400 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

401 

402 
* Some old and rarely used ASCII replacement syntax has been removed. 

403 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

404

430 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

431 

432 
* The alternative notation "\<Colon>" for type and sort constraints has been 

433 
removed: in LaTeX document output it looks the same as "::". 

434 
INCOMPATIBILITY, use plain "::" instead. 

435 

436 
* Commands 'inductive' and 'inductive_set' work better when names for 

437 
intro rules are omitted: the "cases" and "induct" rules no longer 

438 
declare empty case_names, but no case_names at all. This allows to use 

439 
numbered cases in proofs, without requiring method "goal_cases". 

440 

441 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

442 
lowlevel facts of the internal construction only if the option 

443 
"inductive_defs" is enabled. This refers to the internal predicate 

444 
definition and its monotonicity result. Rare INCOMPATIBILITY. 

445 

446 
* Recursive function definitions ('fun', 'function', 'partial_function') 

447 
expose lowlevel facts of the internal construction only if the option 

448 
"function_defs" is enabled. Rare INCOMPATIBILITY. 

449 

450 
* Combinator to represent case distinction on products is named 

451 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

452 
theorem aliasses have been retained.

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

naming policy. 

794 

59951  795 
* Command 'notepad' requires proper nesting of begin/end and its proof

797 
INCOMPATIBILITY, use 'sorry' instead. 

798 

799 
* Command 'named_theorems' declares a dynamic fact within the context, 

800 
together with an attribute to maintain the content incrementally. This 

801 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
863 

864 
* Document markup commands 'chapter', 'section', 'subsection', 

865 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

866 
context, even before the initial 'theory' command. Obsolete proof 

867 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

868 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

869 
instead. The old 'header' command is still retained for some time, but 

870 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

871 
update_header"). Minor INCOMPATIBILITY. 

872 

60009  873 
* Official support for "tt" style variants, via \isatt{...} or 
874 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

875 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

876 
as argument to other macros (such as footnotes). 

877 

878 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

879 
style. 

880 

881 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

882 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

883 

59951  884 
* Diagnostic commands and document markup commands within a proof do not 
885 
affect the command tag for output. Thus commands like 'thm' are subject 

886 
to proof document structure, and no longer "stick out" accidentally. 

887 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

888 
tags. Potential INCOMPATIBILITY in exotic situations. 

889 

890 
* System option "pretty_margin" is superseded by "thy_output_margin", 

891 
which is also accessible via document antiquotation option "margin". 

892 
Only the margin for document output may be changed, but not the global 

893 
pretty printing: that is 76 for plain console output, and adapted 

894 
dynamically in GUI frontends. Implementations of document 

895 
antiquotations need to observe the margin explicitly according to 

896 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

INCOMPATIBILITY. 
58192  957 
 The "no_code" option to "free_constructors", "datatype_new", and 
958 
"codatatype" has been renamed "plugins del: code". 

959 
INCOMPATIBILITY. 

58044  960 
 The rules "set_empty" have been removed. They are easy 
961 
consequences of other set rules "by auto". 

962 
INCOMPATIBILITY. 

963 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  964 
attribute. This can influence the behavior of the "cases" proof 
965 
method when more than one case rule is applicable (e.g., an 

966 
assumption is of the form "w : set ws" and the method "cases w" 

967 
is invoked). The solution is to specify the case rule explicitly 

968 
(e.g. "cases w rule: widget.exhaust").

 Lifting and Transfer setup for basic HOL types sum and prod (also 
979

980 
Lifting_Product and Lifting_Option from Main became obsolete and 

981 
were removed. Changed definitions of the relators rel_prod and 

982 
rel_sum (using inductive). 

60111  983 
INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead 
60114  984 
of rel_prod_def and rel_sum_def.

59965  1012

57737  1020 

58062  1021 
* Old and new SMT modules: 
58067  1022 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  1023 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1024 
until applications have been ported to use the new 'smt' method. For 

1025 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1026 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1027 
point to it. 

58062  1028 
INCOMPATIBILITY. 
58067  1029 
 The 'smt2' method has been renamed 'smt'. 
58060  1030 
INCOMPATIBILITY. 
59569  1031 
 New option 'smt_reconstruction_step_timeout' to limit the 
1032 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  1033 
 New option 'smt_statistics' to display statistics of the new 'smt' 
1034 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  1035 

60261  1036 
* Lifting: command 'lift_definition' allows to execute lifted constants 
1037 
that have as a return type a datatype containing a subtype. This 

1038 
overcomes longtime limitations in the area of code generation and 

1039 
lifting, and avoids tedious workarounds. 

60258  1040 

60009  1041 
* Command and antiquotation "value" provide different evaluation slots 
1042 
(again), where the previous strategy (NBE after ML) serves as default. 

1043 
Minor INCOMPATIBILITY. 

1044 

1045 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

1046 

1047 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

1048 
nontermination in case of distributing a division. With this change 

1049 
field_simps is in some cases slightly less powerful, if it fails try to 

1050 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

1051 

1052 
* Separate class no_zero_divisors has been given up in favour of fully 

1053 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY. 

1054 

1055 
* Class linordered_semidom really requires no zero divisors. 

1056 
INCOMPATIBILITY. 

1057

1059

1060 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.

1071 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be

1073 

1074

1075 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

1076 

1077 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1078 
that admits numeric types including nat, int, real and complex. 

1079 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1080 
constraint, and the combination "real (fact k)" is likely to be 

1081 
unsatisfactory. If a type conversion is still necessary, then use 

1082 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1083 

1084 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1085 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1086 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1087 
"nat_floor"/"nat_ceiling". 

1088 

1089 
* Qualified some duplicated fact names required for boostrapping the 

1090 
type class hierarchy:

1092 
field_inverse_zero ~> inverse_zero 

1093 
field_divide_inverse ~> divide_inverse

1098 
mult_less_imp_less_right ~> mult_right_less_imp_less 

1099 
mult_less_imp_less_left ~> mult_left_less_imp_less 

1100 
Minor INCOMPATIBILITY. 

1101 

1102 
* Fact consolidation: even_less_0_iff is subsumed by 

1103 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

1104 

1105

1106 
dvd_reduce ~> dvd_add_triv_right_iff 

1107 
dvd_plus_eq_right ~> dvd_add_right_iff

* Subtle change of name space policy: undeclared entries are now 
1189 
considered inaccessible, instead of accessible via the fullyqualified 

1190 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1191 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1192 
contemporary applications use the strict Name_Space.check (and

Multithreading.synchronized and its highlevel derivative 

1208 
Synchronized.var (which is usually sufficient in applications). Subtle

* Support for official Standard ML within the Isabelle context. 
1273 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1274 
Toplevel bindings are stored within the theory context; the initial 

1275 
environment is restricted to the Standard ML implementation of 

1276 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1277 
and 'SML_export' allow to exchange toplevel bindings between the two 

1278 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1279

1280 

57504  1281 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1282 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1283 
variable. Locale assumptions and chained facts containing "x" 

1284 
continue to be useful. The new method "hypsubst_thin" and the 

1285 
configuration option "hypsubst_thin" (within the attribute name space) 

1286 
restore the previous behavior. INCOMPATIBILITY, especially where 

1287 
induction is done after these methods or when the names of free and 

1288 
bound variables clash. As first approximation, old proofs may be 

1289 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1290 

56232  1291 
* More static checking of proof methods, which allows the system to 
1292 
form a closure over the concrete syntax. Method arguments should be 

1293 
processed in the original proof context as far as possible, before 

1294 
operating on the goal state. In any case, the standard discipline for 

1295 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1296 
number that is out of range produces an empty result sequence, not an 

1297 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1298 
proof tools. 

1299 

57452  1300 
* Lexical syntax (inner and outer) supports text cartouches with 
1301 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1302 
supports input via ` (backquote). 

1303 

1304 
* The outer syntax categories "text" (for formal comments and document 

1305 
markup commands) and "altstring" (for literal fact references) allow 

1306 
cartouches as well, in addition to the traditional mix of quotations. 

1307 

1308 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1309 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1310 
string token. General renovation of its syntax using text cartouches. 
57452  1311 
Minor INCOMPATIBILITY. 
1312 

1313 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1314 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1315 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1316 
INCOMPATIBILITY. 

1317 

1318 
* Document antiquotation @{url} produces markup for the given URL, 

1319 
which results in an active hyperlink within the text. 

1320 

1321 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1322 
not check existence within the filesystem. 

1323 

1324 
* Updated and extended manuals: codegen, datatypes, implementation, 

1325 
isarref, jedit, system.
