*** 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.

94 
already running Isabelle/jEdit process. This achieves the effect of 

95 
singleinstance applications seen on common GUI desktops.

*** Document preparation *** 
109 

62017  110 
* Commands 'paragraph' and 'subparagraph' provide additional section 
111 
headings. Thus there are 6 levels of standard headings, as in HTML. 

112 

113 
* Command 'text_raw' has been clarified: input text is processed as in 

114 
'text' (with antiquotations and control symbols). The key difference is 

115 
the lack of the surrounding isabelle markup environment in output. 

116 

117 
* Text is structured in paragraphs and nested lists, using notation that 

118 
is similar to Markdown. The control symbols for list items are as 

119 
follows: 

120 

121 
\<^item> itemize 

122 
\<^enum> enumerate 

123 
\<^descr> description

126 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  127 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
128 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  129 
standard Isabelle fonts provide glyphs to render important control 
130 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

131 

61595  132 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
133 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

134 
standard LaTeX macros of the same names.

137 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  138 
text. Commandline tool "isabelle update_cartouches t" helps to update 
139 
old sources, by approximative patching of the content of string and 

140 
cartouche tokens seen in theory sources.

surrounding quotes etc. Subtle INCOMPATIBILITY, put quotes into the 
61494  145 
argument where they are really intended, e.g. @{text \<open>"foo"\<close>}. Initial 
146 
or terminal spaces are ignored.

147 

62017  148 
* Antiquotations @{emph} and @{bold} output LaTeX source recursively, 
149 
adding appropriate text style markup. These may be used in the short 

150 
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>. 

151 

152 
* Document antiquotation @{footnote} outputs LaTeX source recursively, 

153 
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>. 

154 

155 
* Antiquotation @{verbatim [display]} supports option "indent". 

156 

157 
* Antiquotation @{theory_text} prints uninterpreted theory source text 

158 
(outer syntax with command keywords etc.). This may be used in the short 

159 
form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent". 

160 

161 
* Antiquotation @{doc ENTRY} provides a reference to the given 

162 
documentation, with a hyperlink in the Prover IDE. 

163 

164 
* Antiquotations @{command}, @{method}, @{attribute} print checked 

165 
entities of the Isar language. 

166 

61471  167 
* HTML presentation uses the standard IsabelleText font and Unicode 
168 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  169 
print mode "HTML" loses its special meaning.

*** Isar ***

60414  174 
* Local goals ('have', 'show', 'hence', 'thus') allow structured 
61733  175 
rule statements like fixes/assumes/shows in theorem specifications, but 
176 
the notation is postfix with keywords 'if' (or 'when') and 'for'. For 

60555

have result: "C x y"

181 
for x :: 'a and y :: 'a 

182 
<proof> 

183 

60449  184 
The local assumptions are bound to the name "that". The result is 
185 
exported from context of the statement as usual. The above roughly 

60414  186 
corresponds to a raw proof block like this: 
187 

188 
{ 

189 
fix x :: 'a and y :: 'a 

60449  190 
assume that: "A x" "B y" 
60414  191 
have "C x y" <proof> 
192 
} 

193

197 

61733  198 
* Assumptions ('assume', 'presume') allow structured rule statements 
199 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  200 

201 
assume result: "C x y" 

202 
if "A x" and "B y" 

203 
for x :: 'a and y :: 'a 

204 

205 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

206 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

207 

208 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

209 
only effects propositions according to actual use of variables. For 

210 
example: 

211 

212 
assume "A x" and "B y" for x and y 

213 

214 
is equivalent to: 

215 

216 
assume "\<And>x. A x" and "\<And>y. B y" 

217 

60595  218 
* The meaning of 'show' with Pure rule statements has changed: premises 
219 
are treated in the sense of 'assume', instead of 'presume'. This means, 

220 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

221 

222 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

223 

224 
or: 

225 

226 
show "C x" if "A x" "B x" for x 

227 

228 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

229 

230 
show "C x" when "A x" "B x" for x 

231 

60459  232 
* New command 'consider' states rules for generalized elimination and 
233 
case splitting. This is like a toplevel statement "theorem obtains" used 

234 
within a proof body; or like a multibranch 'obtain' without activation 

235 
of the local context elements yet. 

236 

60455  237 
* Proof method "cases" allows to specify the rule as first entry of 
238 
chained facts. This is particularly useful with 'consider': 

239 

240 
consider (a) A  (b) B  (c) C <proof> 

241 
then have something 

242 
proof cases 

243 
case a 

244 
then show ?thesis <proof> 

245 
next 

246 
case b 

247 
then show ?thesis <proof> 

248 
next 

249 
case c 

250 
then show ?thesis <proof> 

251 
qed 

252 

60565  253 
* Command 'case' allows fact name and attribute specification like this: 
254 

255 
case a: (c xs) 

256 
case a [attributes]: (c xs) 

257 

258 
Facts that are introduced by invoking the case context are uniformly 

259 
qualified by "a"; the same name is used for the cumulative fact. The old 

260 
form "case (c xs) [attributes]" is no longer supported. Rare 

261 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

262 
and always put attributes in front.

62017  269 
* Nesting of Isar goal structure has been clarified: the context after 
270 
the initial backwards refinement is retained for the whole proof, within 

271 
all its context sections (as indicated via 'next'). This is e.g. 

272 
relevant for 'using', 'including', 'supply': 

273 

274 
have "A \<and> A" if a: A for A 

275

282 
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the 

283 
proof body as well, abstracted over relevant parameters. 

284 

285 
* Improved typeinference for theorem statement 'obtains': separate 

286 
parameter scope for of each clause. 

287 

288 
* Term abbreviations via 'is' patterns also work for schematic 

289 
statements: result is abstracted over unknowns. 

290 

60631  291 
* Command 'subgoal' allows to impose some structure on backward 
292 
refinements, to avoid proof scripts degenerating into long of 'apply' 

293 
sequences. Further explanations and examples are given in the isarref 

294 
manual. 

295 

62017  296 
* Command 'supply' supports fact definitions during goal refinement

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  324 
is marked as legacy, and will be removed eventually. The proof method 
325 
"goals" achieves a similar effect within regular Isar; often it can be

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

parameters, and only 'notation' is suppressed. This can be of great help 
350 
when working with complex locale hierarchies, because proof states are

* The 'typedef' command has been upgraded from a partially checked 
393 
"axiomatization", to a full definitional specification that takes the 

394 
global collection of overloaded constant / type definitions into 

395 
account. Type definitions with open dependencies on overloaded 

396 
definitions need to be specified as "typedef (overloaded)". This 

397 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

398 

399 
* Qualification of various formal entities in the libraries is done more 

400 
uniformly via "context begin qualified definition ... end" instead of 

401 
oldstyle "hide_const (open) ...". Consequently, both the defined 

402 
constant and its defining fact become qualified, e.g. Option.is_none and 

403 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

404 

405 
* Some old and rarely used ASCII replacement syntax has been removed. 

406 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

407 
The subsequent commands help to reproduce the old forms, e.g. to 

408 
simplify porting old theories:

433 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

434 

435 
* The alternative notation "\<Colon>" for type and sort constraints has been 

436 
removed: in LaTeX document output it looks the same as "::". 

437 
INCOMPATIBILITY, use plain "::" instead. 

438 

439 
* Commands 'inductive' and 'inductive_set' work better when names for 

440 
intro rules are omitted: the "cases" and "induct" rules no longer 

441 
declare empty case_names, but no case_names at all. This allows to use 

442 
numbered cases in proofs, without requiring method "goal_cases". 

443 

444 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

445 
lowlevel facts of the internal construction only if the option 

62093  446 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  447 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
448 

449 
* Recursive function definitions ('fun', 'function', 'partial_function') 

450 
expose lowlevel facts of the internal construction only if the option 

62093  451 
"function_internals" is enabled. Rare INCOMPATIBILITY. 
452 

453 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

454 
of the internal construction only if the option "bnf_internals" is 

455 
enabled. This supersedes the former option "bnf_note_all". Rare 

456 
INCOMPATIBILITY. 

62017  457 

458 
* Combinator to represent case distinction on products is named 

459 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

460 
theorem aliasses have been retained.

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

508 
'real' is no longer overloaded, but has type 'nat => real' and 

509 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

510 
abbreviates of_int for that type. Other overloaded instances of 'real' 

511 
have been replaced by 'real_of_ereal' and 'real_of_float'.

* Command 'experiment' opens an anonymous locale context with private 
829 
naming policy. 

830 

59951  831 
* Command 'notepad' requires proper nesting of begin/end and its proof

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

833 
INCOMPATIBILITY, use 'sorry' instead. 

834 

835 
* Command 'named_theorems' declares a dynamic fact within the context, 

836 
together with an attribute to maintain the content incrementally. This 

837 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

838 
of semantics due to external visual order vs. internal reverse order.

*** Document preparation *** 
899 

900 
* Document markup commands 'chapter', 'section', 'subsection', 

901 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

902 
context, even before the initial 'theory' command. Obsolete proof 

903 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

904 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

905 
instead. The old 'header' command is still retained for some time, but 

906 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

907 
update_header"). Minor INCOMPATIBILITY. 

908 

60009  909 
* Official support for "tt" style variants, via \isatt{...} or 
910 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

911 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

912 
as argument to other macros (such as footnotes). 

913 

914 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

915 
style. 

916 

917 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

918 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

919 

59951  920 
* Diagnostic commands and document markup commands within a proof do not 
921 
affect the command tag for output. Thus commands like 'thm' are subject 

922 
to proof document structure, and no longer "stick out" accidentally. 

923 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

924 
tags. Potential INCOMPATIBILITY in exotic situations. 

925 

926 
* System option "pretty_margin" is superseded by "thy_output_margin", 

927 
which is also accessible via document antiquotation option "margin". 

928 
Only the margin for document output may be changed, but not the global 

929 
pretty printing: that is 76 for plain console output, and adapted 

930 
dynamically in GUI frontends. Implementations of document 

931 
antiquotations need to observe the margin explicitly according to 

932 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* New (co)datatype package: 
58373  973 
 The 'datatype_new' command has been renamed 'datatype'. The old 
974 
command of that name is now called 'old_datatype' and is provided 

975 
by "~~/src/HOL/Library/Old_Datatype.thy". See

INCOMPATIBILITY. 
58192  993 
 The "no_code" option to "free_constructors", "datatype_new", and 
994 
"codatatype" has been renamed "plugins del: code". 

995 
INCOMPATIBILITY. 

58044  996 
 The rules "set_empty" have been removed. They are easy 
997 
consequences of other set rules "by auto". 

998 
INCOMPATIBILITY. 

999 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  1000 
attribute. This can influence the behavior of the "cases" proof 
1001 
method when more than one case rule is applicable (e.g., an 

1002 
assumption is of the form "w : set ws" and the method "cases w" 

1003 
is invoked). The solution is to specify the case rule explicitly 

1004 
(e.g. "cases w rule: widget.exhaust"). 

1005 
INCOMPATIBILITY.

INCOMPATIBILITY. 

60114  1014 
 Lifting and Transfer setup for basic HOL types sum and prod (also 
1015 
option) is now performed by the BNF package. Theories Lifting_Sum, 

1016 
Lifting_Product and Lifting_Option from Main became obsolete and 

1017 
were removed. Changed definitions of the relators rel_prod and 

1018 
rel_sum (using inductive). 

60111  1019 
INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead 
60114  1020 
of rel_prod_def and rel_sum_def. 
1021 
Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names 

1022 
changed (e.g. map_prod_transfer ~> prod.map_transfer). 

60261  1023 
 Parametricity theorems for map functions, relators, set functions, 
1024 
constructors, case combinators, discriminators, selectors and 

1025 
(co)recursors are automatically proved and registered as transfer 

1026 
rules.

* Nitpick: 
60010  1042 
 Fixed soundness bug related to the strict and nonstrict subset 
59039  1043 
operations. 
1044 

57737  1045

59511  1046 
 CVC4 is now included with Isabelle instead of CVC3 and run by 
1047 
default. 

59965  1048 
 Z3 is now always enabled by default, now that it is fully open 
1049 
source. The "z3_non_commercial" option is discontinued. 

57737  1050 
 Minimization is now always enabled by default. 
60010  1051 
Removed subcommand: 
57737  1052

59967  1053 
 Proof reconstruction, both oneliners and Isar, has been 
59039  1054 
dramatically improved. 
1055 
 Improved support for CVC4 and veriT. 

57737  1056 

58062  1057 
* Old and new SMT modules: 
58067  1058 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  1059 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1060 
until applications have been ported to use the new 'smt' method. For 

1061 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1062 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1063 
point to it. 

58062  1064 
INCOMPATIBILITY. 
58067  1065 
 The 'smt2' method has been renamed 'smt'. 
58060  1066 
INCOMPATIBILITY. 
59569  1067 
 New option 'smt_reconstruction_step_timeout' to limit the 
1068 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  1069 
 New option 'smt_statistics' to display statistics of the new 'smt' 
1070 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  1071 

60261  1072 
* Lifting: command 'lift_definition' allows to execute lifted constants 
1073 
that have as a return type a datatype containing a subtype. This 

1074 
overcomes longtime limitations in the area of code generation and 

1075 
lifting, and avoids tedious workarounds. 

60258  1076 

60009  1077 
* Command and antiquotation "value" provide different evaluation slots 
1078 
(again), where the previous strategy (NBE after ML) serves as default. 

1079 
Minor INCOMPATIBILITY. 

1080 

1081 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

1082 

1083 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

1084 
nontermination in case of distributing a division. With this change 

1085 
field_simps is in some cases slightly less powerful, if it fails try to 

1086 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

1087 

1088 
* Separate class no_zero_divisors has been given up in favour of fully 

1089 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY. 

1090 

1091 
* Class linordered_semidom really requires no zero divisors. 

1092 
INCOMPATIBILITY. 

1093 

1094 
* Classes division_ring, field and linordered_field always demand 

1095 
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero, 

1096 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY. 

1097

"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

1107 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be

needed. 

1109 

1110

1111 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

1112 

1113 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1114 
that admits numeric types including nat, int, real and complex. 

1115 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1116 
constraint, and the combination "real (fact k)" is likely to be 

1117 
unsatisfactory. If a type conversion is still necessary, then use 

1118 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1119 

1120 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1121 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1122 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1123 
"nat_floor"/"nat_ceiling". 

1124 

1125 
* Qualified some duplicated fact names required for boostrapping the 

1126 
type class hierarchy: 

1127 
ab_add_uminus_conv_diff ~> diff_conv_add_uminus 

1128 
field_inverse_zero ~> inverse_zero 

1129 
field_divide_inverse ~> divide_inverse 

1130 
field_inverse ~> left_inverse 

1131 
Minor INCOMPATIBILITY. 

1132 

1133

1134 
mult_less_imp_less_right ~> mult_right_less_imp_less 

1135 
mult_less_imp_less_left ~> mult_left_less_imp_less 

1136 
Minor INCOMPATIBILITY. 

1137 

1138 
* Fact consolidation: even_less_0_iff is subsumed by 

1139 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

1140 

1141 
* Generalized and consolidated some theorems concerning divsibility: 

1142 
dvd_reduce ~> dvd_add_triv_right_iff 

1143 
dvd_plus_eq_right ~> dvd_add_right_iff 

1144 
dvd_plus_eq_left ~> dvd_add_left_iff 

1145 
Minor INCOMPATIBILITY. 

1146

1148

1158 
INCOMPATIBILITY.

60009  1224 
* Subtle change of name space policy: undeclared entries are now 
1225 
considered inaccessible, instead of accessible via the fullyqualified 

1226 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1227 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1228 
contemporary applications use the strict Name_Space.check (and 
60009  1229

1230 
INCOMPATIBILITY in rare applications of Name_Space.intern.

Toplevel bindings are stored within the theory context; the initial 

1311 
environment is restricted to the Standard ML implementation of 

1312 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1313

1316 

57504  1317 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1318 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1319 
variable. Locale assumptions and chained facts containing "x" 

1320 
continue to be useful. The new method "hypsubst_thin" and the 

1321 
configuration option "hypsubst_thin" (within the attribute name space) 

1322 
restore the previous behavior. INCOMPATIBILITY, especially where 

1323 
induction is done after these methods or when the names of free and 

1324 
bound variables clash. As first approximation, old proofs may be 

1325 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1326 

56232  1327 
* More static checking of proof methods, which allows the system to 
1328 
form a closure over the concrete syntax. Method arguments should be 

1329 
processed in the original proof context as far as possible, before 

1330 
operating on the goal state. In any case, the standard discipline for 

1331 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1332 
number that is out of range produces an empty result sequence, not an 

1333 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1334 
proof tools. 

1335 

57452  1336 
* Lexical syntax (inner and outer) supports text cartouches with 
1337 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1338 
supports input via ` (backquote). 

1339 

1340 
* The outer syntax categories "text" (for formal comments and document 

1341 
markup commands) and "altstring" (for literal fact references) allow 

1342 
cartouches as well, in addition to the traditional mix of quotations. 

1343 

1344 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1345 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1346 
string token. General renovation of its syntax using text cartouches. 
57452  1347 
Minor INCOMPATIBILITY. 
1348 

1349 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1350 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1351 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1352 
INCOMPATIBILITY. 

1353 

1354 
* Document antiquotation @{url} produces markup for the given URL, 

1355 
which results in an active hyperlink within the text. 

1356 

1357 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1358 
not check existence within the filesystem. 

1359 

1360

1361 
isarref, jedit, system.
