* Toplevel theorem statements have been simplified as follows: 

13 

14 
theorems ~> lemmas 

15 
schematic_lemma ~> schematic_goal 

16 
schematic_theorem ~> schematic_goal 

17 
schematic_corollary ~> schematic_goal

19 
Commandline tool "isabelle update_theorems" updates theory sources 

20 
accordingly. 

21 

61338  22 
* Toplevel theorem statement 'proposition' is another alias for 
23 
'theorem'. 

24 

61579  25 
* Syntax for formal comments " text" now also supports the symbolic 
26 
form "\<comment> text". Commandline tool "isabelle update_cartouches c" helps 

27 
to update old sources.

60986  39 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  40 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
41 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

42 
'SML_file_no_debug' control compilation of sources with debugging 

43 
information. The Debugger panel allows to set breakpoints (via context 

44 
menu), step through stopped threads, evaluate local ML expressions etc. 

45 
At least one Debugger view needs to be active to have any effect on the 

46 
running ML program. 

47 

61173  48 
* The main Isabelle executable is managed as singleinstance Desktop 
49 
application uniformly on all platforms: Linux, Windows, Mac OS X. 

61170  50 

61198  51 
* The text overview column (status of errors, warnings etc.) is updated 
52 
asynchronously, leading to much better editor reactivity. Moreover, the 

53 
full document node content is taken into account. 

54 

61729  55 
* The State panel manages explicit proof state output. The jEdit action 
56 
"isabelle.updatestate" (shortcut S+ENTER) triggers manual update 

57 
according to cursor position. 

58 

59 
* The Output panel no longer shows proof state output by default, to 

60 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

61 
enable option "editor_output_state". 

61215  62 

61483  63 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
64 
emphasized text style; the effect is visible in document output, not in 

65 
the editor. 

66 

67 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

68 
instead of former C+e LEFT.

that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  88 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
89 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  90 
standard Isabelle fonts provide glyphs to render important control 
91 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

* Antiquotations @{command}, @{method}, @{attribute} print checked 
101 
entities of the Isar language. 

102 

61595  103 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
104 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

105 
standard LaTeX macros of the same names.

108 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  109 
text. Commandline tool "isabelle update_cartouches t" helps to update 
110 
old sources, by approximative patching of the content of string and 

111 
cartouche tokens seen in theory sources.

61471  119 
* HTML presentation uses the standard IsabelleText font and Unicode 
120 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  121 
print mode "HTML" loses its special meaning. 
61471  122 

61463  123 
* Commands 'paragraph' and 'subparagraph' provide additional section 
124 
headings. Thus there are 6 levels of standard headings, as in HTML. 

125 

126 
* Text is structured in paragraphs and nested lists, using notation that 

127 
is similar to Markdown. The control symbols for list items are as 

128 
follows: 

129 

130 
\<^item> itemize 

131 
\<^enum> enumerate 

132 
\<^descr> description 

133 

134 
* Command 'text_raw' has been clarified: input text is processed as in 

135 
'text' (with antiquotations and control symbols). The key difference is 

136 
the lack of the surrounding isabelle markup environment in output.

140 
the short form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>.

* Local goals ('have', 'show', 'hence', 'thus') allow structured 
61733  158 
rule statements like fixes/assumes/shows in theorem specifications, but 
159 
the notation is postfix with keywords 'if' (or 'when') and 'for'. For

164 
for x :: 'a and y :: 'a 

165 
<proof> 

166 

60449  167 
The local assumptions are bound to the name "that". The result is 
168 
exported from context of the statement as usual. The above roughly 

60414  169 
corresponds to a raw proof block like this: 
170 

171 
{ 

172 
fix x :: 'a and y :: 'a 

60449  173 
assume that: "A x" "B y" 
60414  174 
have "C x y" <proof> 
175 
}

180 

61733  181 
* Assumptions ('assume', 'presume') allow structured rule statements 
182 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  183 

184 
assume result: "C x y" 

185 
if "A x" and "B y" 

186 
for x :: 'a and y :: 'a 

187 

188 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

189 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

190 

191 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

192 
only effects propositions according to actual use of variables. For 

193 
example: 

194 

195 
assume "A x" and "B y" for x and y 

196 

197 
is equivalent to: 

198 

199 
assume "\<And>x. A x" and "\<And>y. B y" 

200 

60595  201 
* The meaning of 'show' with Pure rule statements has changed: premises 
202 
are treated in the sense of 'assume', instead of 'presume'. This means, 

203 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

204 

205 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

206 

207 
or: 

208 

209 
show "C x" if "A x" "B x" for x 

210 

211 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

212 

213 
show "C x" when "A x" "B x" for x 

214 

60406  215 
* New command 'supply' supports fact definitions during goal refinement 
216 
('apply' scripts). 

217 

60459  218 
* New command 'consider' states rules for generalized elimination and 
219 
case splitting. This is like a toplevel statement "theorem obtains" used 

220 
within a proof body; or like a multibranch 'obtain' without activation 

221 
of the local context elements yet. 

222 

60455  223 
* Proof method "cases" allows to specify the rule as first entry of 
224 
chained facts. This is particularly useful with 'consider': 

225 

226 
consider (a) A  (b) B  (c) C <proof> 

227 
then have something 

228 
proof cases 

229 
case a 

230 
then show ?thesis <proof> 

231 
next 

232 
case b 

233 
then show ?thesis <proof> 

234 
next 

235 
case c 

236 
then show ?thesis <proof> 

237 
qed 

238 

60565  239 
* Command 'case' allows fact name and attribute specification like this: 
240 

241 
case a: (c xs) 

242 
case a [attributes]: (c xs) 

243 

244 
Facts that are introduced by invoking the case context are uniformly 

245 
qualified by "a"; the same name is used for the cumulative fact. The old 

246 
form "case (c xs) [attributes]" is no longer supported. Rare 

247 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

248 
and always put attributes in front.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  285 
is marked as legacy, and will be removed eventually. The proof method 
286 
"goals" achieves a similar effect within regular Isar; often it can be 

287 
done more adequately by other means (e.g. 'consider').

* Nesting of Isar goal structure has been clarified: the context after 
290 
the initial backwards refinement is retained for the whole proof, within 

291 
all its context sections (as indicated via 'next'). This is e.g. 

292 
relevant for 'using', 'including', 'supply':

*** Document preparation *** 
797 

798 
* Document markup commands 'chapter', 'section', 'subsection', 

799 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

800 
context, even before the initial 'theory' command. Obsolete proof 

801 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

802 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

803 
instead. The old 'header' command is still retained for some time, but 

804 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

805 
update_header"). Minor INCOMPATIBILITY. 

806 

60009  807 
* Official support for "tt" style variants, via \isatt{...} or 
808 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

809 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

810 
as argument to other macros (such as footnotes). 

811 

812 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

813 
style. 

814 

815 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

816 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

817 

59951  818 
* Diagnostic commands and document markup commands within a proof do not 
819 
affect the command tag for output. Thus commands like 'thm' are subject 

820 
to proof document structure, and no longer "stick out" accidentally. 

821 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

822 
tags. Potential INCOMPATIBILITY in exotic situations. 

823 

824 
* System option "pretty_margin" is superseded by "thy_output_margin", 

825 
which is also accessible via document antiquotation option "margin". 

826 
Only the margin for document output may be changed, but not the global 

827 
pretty printing: that is 76 for plain console output, and adapted 

828 
dynamically in GUI frontends. Implementations of document 

829 
antiquotations need to observe the margin explicitly according to 

830 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* The functions "sin" and "cos" are now defined for any type of sort 
1004 
"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

1005 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be 

1006 
needed. 

1007 

1008 
* New library of properties of the complex transcendental functions sin, 

1009 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

1010 

1011 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1012 
that admits numeric types including nat, int, real and complex. 

1013 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1014 
constraint, and the combination "real (fact k)" is likely to be 

1015 
unsatisfactory. If a type conversion is still necessary, then use 

1016 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1017 

1018 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1019 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1020 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1021 
"nat_floor"/"nat_ceiling". 

1022 

1023 
* Qualified some duplicated fact names required for boostrapping the 

1024 
type class hierarchy:

1026

mult_less_imp_less_right ~> mult_right_less_imp_less 

1033 
mult_less_imp_less_left ~> mult_left_less_imp_less 

1034

1035 

1036

1037 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

1038 

1039

dvd_reduce ~> dvd_add_triv_right_iff 

1041 
dvd_plus_eq_right ~> dvd_add_right_iff 

1042 
dvd_plus_eq_left ~> dvd_add_left_iff 

1043

60009  1122 
* Subtle change of name space policy: undeclared entries are now 
1123 
considered inaccessible, instead of accessible via the fullyqualified 

1124 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1125 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1126 
contemporary applications use the strict Name_Space.check (and 
60009  1127 
derivatives) instead, which is not affected by the change. Potential 
1128 
INCOMPATIBILITY in rare applications of Name_Space.intern. 

59951  1129

INCOMPATIBILITY.

Multithreading.synchronized and its highlevel derivative 

1142 
Synchronized.var (which is usually sufficient in applications). Subtle 

1143 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

1144 
nested. 

1145 

60009  1146

* Support for official Standard ML within the Isabelle context. 
1207 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1208 
Toplevel bindings are stored within the theory context; the initial 

1209 
environment is restricted to the Standard ML implementation of 

1210 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1211

1212

1214 

57504  1215 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1216 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1217 
variable. Locale assumptions and chained facts containing "x" 

1218 
continue to be useful. The new method "hypsubst_thin" and the 

1219 
configuration option "hypsubst_thin" (within the attribute name space) 

1220 
restore the previous behavior. INCOMPATIBILITY, especially where 

1221 
induction is done after these methods or when the names of free and 

1222 
bound variables clash. As first approximation, old proofs may be 

1223 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1224 

56232  1225 
* More static checking of proof methods, which allows the system to 
1226 
form a closure over the concrete syntax. Method arguments should be 

1227 
processed in the original proof context as far as possible, before 

1228 
operating on the goal state. In any case, the standard discipline for 

1229 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1230 
number that is out of range produces an empty result sequence, not an 

1231 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1232 
proof tools. 

1233 

57452  1234 
* Lexical syntax (inner and outer) supports text cartouches with 
1235 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1236 
supports input via ` (backquote). 

1237 

1238 
* The outer syntax categories "text" (for formal comments and document 

1239 
markup commands) and "altstring" (for literal fact references) allow 

1240 
cartouches as well, in addition to the traditional mix of quotations. 

1241 

1242 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1243 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1244 
string token. General renovation of its syntax using text cartouches. 
57452  1245 
Minor INCOMPATIBILITY. 
1246 

1247 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1248 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1249 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1250 
INCOMPATIBILITY. 

1251 

1252 
* Document antiquotation @{url} produces markup for the given URL, 

1253 
which results in an active hyperlink within the text.

57504  1330 
* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1331 
been discontinued to avoid the danger of nontrivial axiomatization 

1332 
that is not immediately visible. INCOMPATIBILITY, use regular 

1333 
'instance' command with proof. The required OFCLASS(...) theorem 

1334 
might be postulated via 'axiomatization' beforehand, or the proof 

1335 
finished trivially if the underlying class definition is made vacuous 

1336 
(without any assumptions). See also Isabelle/ML operations 

1337 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1338 
Axclass.arity_axiomatization. 

1339 

56245  1340 
* Basic constants of Pure use more conventional names and are always 
1341 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1342 
consequences, notably for tools in Isabelle/ML. The following 

1343 
renaming needs to be applied: 

1344 

1345 
== ~> Pure.eq 

1346 
==> ~> Pure.imp 

1347 
all ~> Pure.all 

1348 
TYPE ~> Pure.type 

1349 
dummy_pattern ~> Pure.dummy_pattern 

1350 

1351 
Systematic porting works by using the following theory setup on a 

1352 
*previous* Isabelle version to introduce the new name accesses for the 

1353 
old constants: 

1354 

1355 
setup {* 

1356 
fn thy => thy 

1357 
> Sign.root_path 

1358 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1359 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1360 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1361 
> Sign.restore_naming thy 

1362 
*} 

1363 

1364 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1365 
Later the application is moved to the current Isabelle version, and 

1366 
the auxiliary aliases are deleted.

55152  1372 
* Obsolete attribute "standard" has been discontinued (legacy since 
1373 
Isabelle2012). Potential INCOMPATIBILITY, use explicit 'for' context 

1374 
where instantiations with schematic variables are intended (for 

1375 
declaration commands like 'lemmas' or attributes like "of"). The 

1376 
following temporary definition may help to port old applications: 

1377 

1378 
attribute_setup standard = 

1379 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

1380 

55001  1381 
* More thorough check of proof context for goal statements and 
55006  1382 
attributed fact expressions (concerning background theory, declared 
1383 
hyps). Potential INCOMPATIBILITY, tools need to observe standard 

1384 
context discipline. See also Assumption.add_assumes and the more 

1385 
primitive Thm.assume_hyps.
