*** General ***

* 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 

18 

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. 

28 

61958  29 
* Former "xsymbols" syntax with Isabelle symbols is used by default, 
30 
without any special print mode. Important ASCII replacement syntax 

31 
remains available under print mode "ASCII", but less important syntax 

32 
has been removed (see below). 

33 

61964  34 
* Support for more arrow symbols, with rendering in LaTeX and 
35 
Isabelle fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>

60986  50 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  51 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
52 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

53 
'SML_file_no_debug' control compilation of sources with debugging 

54 
information. The Debugger panel allows to set breakpoints (via context 

55 
menu), step through stopped threads, evaluate local ML expressions etc. 

56 
At least one Debugger view needs to be active to have any effect on the 

57 
running ML program. 

58 

61173  59 
* The main Isabelle executable is managed as singleinstance Desktop 
60 
application uniformly on all platforms: Linux, Windows, Mac OS X. 

61170  61 

61803  62 
* The State panel manages explicit proof state output, with dynamic 
63 
autoupdate according to cursor movement. Alternatively, the jEdit 

64 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

65 
update. 

61729  66 

67 
* The Output panel no longer shows proof state output by default, to 

68 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

69 
enable option "editor_output_state". 

61215  70 

61803  71 
* The text overview column (status of errors, warnings etc.) is updated 
72 
asynchronously, leading to much better editor reactivity. Moreover, the 

73 
full document node content is taken into account. The width of the 

74 
column is scaled according to the main text area font, for improved 

75 
visibility. 

76 

77 
* The main text area no longer changes its color hue in outdated 

78 
situations. The text overview column takes over the role to indicate 

79 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

80 
due to adhoc updates by auxiliary GUI components, such as the State 

81 
panel. 

82 

61483  83 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
84 
emphasized text style; the effect is visible in document output, not in 

85 
the editor. 

86 

87 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

88 
instead of former C+e LEFT.

that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  108 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
109 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  110 
standard Isabelle fonts provide glyphs to render important control 
111 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

61748  115 
form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent".

124 

61595  125 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
126 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

127 
standard LaTeX macros of the same names.

130 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  131

132 
old sources, by approximative patching of the content of string and 

133 
cartouche tokens seen in theory sources.

61471  141 
* HTML presentation uses the standard IsabelleText font and Unicode 
142 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  143 
print mode "HTML" loses its special meaning. 
61471  144 

61463  145 
* Commands 'paragraph' and 'subparagraph' provide additional section 
146 
headings. Thus there are 6 levels of standard headings, as in HTML. 

147 

148 
* Text is structured in paragraphs and nested lists, using notation that 

149 
is similar to Markdown. The control symbols for list items are as 

150 
follows: 

151 

152 
\<^item> itemize 

153 
\<^enum> enumerate 

154 
\<^descr> description 

155 

156 
* Command 'text_raw' has been clarified: input text is processed as in 

157 
'text' (with antiquotations and control symbols). The key difference is 

158 
the lack of the surrounding isabelle markup environment in output.

* Local goals ('have', 'show', 'hence', 'thus') allow structured

181 
the notation is postfix with keywords 'if' (or 'when') and 'for'. For

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

187 
<proof> 

188 

60449  189 
The local assumptions are bound to the name "that". The result is 
190 
exported from context of the statement as usual. The above roughly 

60414  191 
corresponds to a raw proof block like this: 
192 

193 
{ 

194 
fix x :: 'a and y :: 'a 

60449  195 
assume that: "A x" "B y" 
60414  196 
have "C x y" <proof> 
197 
}

202 

61733  203 
* Assumptions ('assume', 'presume') allow structured rule statements 
204 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  205 

206 
assume result: "C x y" 

207 
if "A x" and "B y" 

208 
for x :: 'a and y :: 'a 

209 

210 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

211 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

212 

213 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

214 
only effects propositions according to actual use of variables. For 

215 
example: 

216 

217 
assume "A x" and "B y" for x and y 

218 

219 
is equivalent to: 

220 

221 
assume "\<And>x. A x" and "\<And>y. B y" 

222 

60595  223 
* The meaning of 'show' with Pure rule statements has changed: premises 
224 
are treated in the sense of 'assume', instead of 'presume'. This means, 

225 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

226 

227 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

228 

229 
or: 

230 

231 
show "C x" if "A x" "B x" for x 

232 

233 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

234 

235 
show "C x" when "A x" "B x" for x 

236 

60406  237 
* New command 'supply' supports fact definitions during goal refinement 
238 
('apply' scripts). 

239 

60459  240 
* New command 'consider' states rules for generalized elimination and 
241 
case splitting. This is like a toplevel statement "theorem obtains" used 

242 
within a proof body; or like a multibranch 'obtain' without activation 

243 
of the local context elements yet. 

244 

60455  245 
* Proof method "cases" allows to specify the rule as first entry of 
246 
chained facts. This is particularly useful with 'consider': 

247 

248 
consider (a) A  (b) B  (c) C <proof> 

249 
then have something 

250 
proof cases 

251 
case a 

252 
then show ?thesis <proof> 

253 
next 

254 
case b 

255 
then show ?thesis <proof> 

256 
next 

257 
case c 

258 
then show ?thesis <proof> 

259 
qed 

260 

60565  261 
* Command 'case' allows fact name and attribute specification like this: 
262 

263 
case a: (c xs) 

264 
case a [attributes]: (c xs) 

265 

266 
Facts that are introduced by invoking the case context are uniformly 

267 
qualified by "a"; the same name is used for the cumulative fact. The old 

268 
form "case (c xs) [attributes]" is no longer supported. Rare 

269

314 
relevant for 'using', 'including', 'supply':

* Qualification of various formal entities in the libraries is done more 
448 
uniformly via "context begin qualified definition ... end" instead of 

449 
oldstyle "hide_const (open) ...". Consequently, both the defined 

450 
constant and its defining fact become qualified, e.g. Option.is_none and 

451 
Option.is_none_def. Occasional INCOMPATIBILITY in applications.

793

794 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
856 

857 
* Document markup commands 'chapter', 'section', 'subsection', 

858 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

859 
context, even before the initial 'theory' command. Obsolete proof 

860 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

861 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

862 
instead. The old 'header' command is still retained for some time, but 

863 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

864 
update_header"). Minor INCOMPATIBILITY. 

865 

60009  866 
* Official support for "tt" style variants, via \isatt{...} or 
867 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

868 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

869 
as argument to other macros (such as footnotes). 

870 

871 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

872 
style. 

873 

874 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

875 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

876 

59951  877 
* Diagnostic commands and document markup commands within a proof do not 
878 
affect the command tag for output. Thus commands like 'thm' are subject 

879 
to proof document structure, and no longer "stick out" accidentally. 

880 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

881 
tags. Potential INCOMPATIBILITY in exotic situations. 

882 

883 
* System option "pretty_margin" is superseded by "thy_output_margin", 

884 
which is also accessible via document antiquotation option "margin". 

885 
Only the margin for document output may be changed, but not the global 

886 
pretty printing: that is 76 for plain console output, and adapted 

887 
dynamically in GUI frontends. Implementations of document 

888 
antiquotations need to observe the margin explicitly according to 

889 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

1012 
 Improved support for CVC4 and veriT. 

57737  1013 

58062  1014 
* Old and new SMT modules: 
58067  1015 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  1016 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1017 
until applications have been ported to use the new 'smt' method. For 

1018 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1019 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1020 
point to it. 

58062  1021 
INCOMPATIBILITY. 
58067  1022 
 The 'smt2' method has been renamed 'smt'. 
58060  1023 
INCOMPATIBILITY. 
59569  1024 
 New option 'smt_reconstruction_step_timeout' to limit the 
1025 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  1026 
 New option 'smt_statistics' to display statistics of the new 'smt' 
1027 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  1028 

60261  1029 
* Lifting: command 'lift_definition' allows to execute lifted constants 
1030 
that have as a return type a datatype containing a subtype. This 

1031 
overcomes longtime limitations in the area of code generation and 

1032 
lifting, and avoids tedious workarounds. 

60258  1033 

60009  1034 
* Command and antiquotation "value" provide different evaluation slots 
1035 
(again), where the previous strategy (NBE after ML) serves as default. 

1036 
Minor INCOMPATIBILITY. 

1037 

1038 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

1039 

1040 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

1041 
nontermination in case of distributing a division. With this change 

1042 
field_simps is in some cases slightly less powerful, if it fails try to 

1043 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

1044 

1045

1046

1053 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.

1063

1064 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be 

1065

1066 

1067 
* New library of properties of the complex transcendental functions sin, 

1068 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

1069 

1070 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1071 
that admits numeric types including nat, int, real and complex. 

1072 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1073 
constraint, and the combination "real (fact k)" is likely to be 

1074 
unsatisfactory. If a type conversion is still necessary, then use 

1075 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1076 

1077 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1078 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1079 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1080 
"nat_floor"/"nat_ceiling". 

1081 

1082 
* Qualified some duplicated fact names required for boostrapping the 

1083 
type class hierarchy:

1085 
field_inverse_zero ~> inverse_zero 

1086 
field_divide_inverse ~> divide_inverse

1091 
mult_less_imp_less_right ~> mult_right_less_imp_less 

1092 
mult_less_imp_less_left ~> mult_left_less_imp_less 

1093 
Minor INCOMPATIBILITY. 

1094 

1095 
* Fact consolidation: even_less_0_iff is subsumed by 

1096 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

1097 

1098

1099 
dvd_reduce ~> dvd_add_triv_right_iff 

1100 
dvd_plus_eq_right ~> dvd_add_right_iff 

1101 
dvd_plus_eq_left ~> dvd_add_left_iff

60009  1181 
* Subtle change of name space policy: undeclared entries are now 
1182 
considered inaccessible, instead of accessible via the fullyqualified 

1183 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1184 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1185 
contemporary applications use the strict Name_Space.check (and 
60009  1186 
derivatives) instead, which is not affected by the change. Potential 
1187 
INCOMPATIBILITY in rare applications of Name_Space.intern.

Multithreading.synchronized and its highlevel derivative 

1201 
Synchronized.var (which is usually sufficient in applications). Subtle

* Support for official Standard ML within the Isabelle context. 
1266 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1267 
Toplevel bindings are stored within the theory context; the initial 

1268 
environment is restricted to the Standard ML implementation of 

1269 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1270 
and 'SML_export' allow to exchange toplevel bindings between the two 

1271 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1272 
some examples.

1273 

57504  1274 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1275 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1276 
variable. Locale assumptions and chained facts containing "x" 

1277 
continue to be useful. The new method "hypsubst_thin" and the 

1278 
configuration option "hypsubst_thin" (within the attribute name space) 

1279 
restore the previous behavior. INCOMPATIBILITY, especially where 

1280 
induction is done after these methods or when the names of free and 

1281 
bound variables clash. As first approximation, old proofs may be 

1282 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1283 

56232  1284 
* More static checking of proof methods, which allows the system to 
1285 
form a closure over the concrete syntax. Method arguments should be 

1286 
processed in the original proof context as far as possible, before 

1287 
operating on the goal state. In any case, the standard discipline for 

1288 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1289 
number that is out of range produces an empty result sequence, not an 

1290 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1291 
proof tools. 

1292 

57452  1293 
* Lexical syntax (inner and outer) supports text cartouches with 
1294 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1295 
supports input via ` (backquote). 

1296 

1297 
* The outer syntax categories "text" (for formal comments and document 

1298 
markup commands) and "altstring" (for literal fact references) allow 

1299 
cartouches as well, in addition to the traditional mix of quotations. 

1300 

1301 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1302 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1303 
string token. General renovation of its syntax using text cartouches. 
57452  1304 
Minor INCOMPATIBILITY. 
1305 

1306 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1307 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1308 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1309 
INCOMPATIBILITY. 

1310 

1311 
* Document antiquotation @{url} produces markup for the given URL, 

1312 
which results in an active hyperlink within the text. 

1313 

1314 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1315 
not check existence within the filesystem. 

1316 

1317 
* Updated and extended manuals: codegen, datatypes, implementation, 

1318 
isarref, jedit, system.

* Improved Document panel: simplified interaction where every single 
57452  1324 
mouse click (re)opens document via desktop environment or as jEdit 
1325 
buffer. 

1326 

1327 
* Support for Navigator plugin (with toolbar buttons), with connection 

1328 
to PIDE hyperlinks. 

1329 

1330 
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE. 

1331 
Open text buffers take precedence over copies within the filesystem. 

1332 

1333 
* Improved support for Isabelle/ML, with jEdit mode "isabelleml" for 

1334 
auxiliary ML files.
