* 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 

61218  55 
* The State panel manages explicit proof state output, with jEdit action 
56 
"isabelle.updatestate" (shortcut S+ENTER) to trigger update according 

61604  57 
to cursor position. 
58 

59 
* The Output panel no longer shows proof state output by default. This 

60 
reduces resource requirements of prover time and GUI space. 

61 
INCOMPATIBILITY, use the State panel instead or enable option 

62 
"editor_output_state". 

61215  63 

61483  64 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
65 
emphasized text style; the effect is visible in document output, not in 

66 
the editor. 

67 

68 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

69 
instead of former C+e LEFT.

that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  89 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
90 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  91 
standard Isabelle fonts provide glyphs to render important control 
92 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

61595  94 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
95 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

96 
standard LaTeX macros of the same names.

99 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  100 
text. Commandline tool "isabelle update_cartouches t" helps to update 
101 
old sources, by approximative patching of the content of string and 

102 
cartouche tokens seen in theory sources.

61471  110 
* HTML presentation uses the standard IsabelleText font and Unicode 
111 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  112 
print mode "HTML" loses its special meaning. 
61471  113 

61463  114 
* Commands 'paragraph' and 'subparagraph' provide additional section 
115 
headings. Thus there are 6 levels of standard headings, as in HTML. 

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 

124 

125 
* Command 'text_raw' has been clarified: input text is processed as in 

126 
'text' (with antiquotations and control symbols). The key difference is 

127 
the lack of the surrounding isabelle markup environment in output.

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

156 
<proof> 

157 

60449  158 
The local assumptions are bound to the name "that". The result is 
159 
exported from context of the statement as usual. The above roughly 

60414  160 
corresponds to a raw proof block like this: 
161 

162 
{ 

163 
fix x :: 'a and y :: 'a 

60449  164 
assume that: "A x" "B y"

171 

60595  172 
* The meaning of 'show' with Pure rule statements has changed: premises 
173 
are treated in the sense of 'assume', instead of 'presume'. This means, 

174 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

175 

176 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

177 

178 
or: 

179 

180 
show "C x" if "A x" "B x" for x 

181 

182 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

183 

184 
show "C x" when "A x" "B x" for x 

185 

60406  186 
* New command 'supply' supports fact definitions during goal refinement 
187 
('apply' scripts). 

188 

60459  189 
* New command 'consider' states rules for generalized elimination and 
190 
case splitting. This is like a toplevel statement "theorem obtains" used 

191 
within a proof body; or like a multibranch 'obtain' without activation 

192 
of the local context elements yet. 

193 

60455  194 
* Proof method "cases" allows to specify the rule as first entry of 
195 
chained facts. This is particularly useful with 'consider': 

196 

197 
consider (a) A  (b) B  (c) C <proof> 

198 
then have something 

199 
proof cases 

200 
case a 

201 
then show ?thesis <proof> 

202 
next 

203 
case b 

204 
then show ?thesis <proof> 

205 
next 

206 
case c 

207 
then show ?thesis <proof> 

208 
qed 

209 

60565  210 
* Command 'case' allows fact name and attribute specification like this: 
211 

212 
case a: (c xs) 

213 
case a [attributes]: (c xs) 

214 

215 
Facts that are introduced by invoking the case context are uniformly 

216 
qualified by "a"; the same name is used for the cumulative fact. The old 

217 
form "case (c xs) [attributes]" is no longer supported. Rare 

218 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

219 
and always put attributes in front.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  256 
is marked as legacy, and will be removed eventually. The proof method 
257 
"goals" achieves a similar effect within regular Isar; often it can be 

258 
done more adequately by other means (e.g. 'consider').

* Nesting of Isar goal structure has been clarified: the context after 
261 
the initial backwards refinement is retained for the whole proof, within 

262 
all its context sections (as indicated via 'next'). This is e.g. 

263 
relevant for 'using', 'including', 'supply':

629 

59951  630 
* Command 'notepad' requires proper nesting of begin/end and its proof

INCOMPATIBILITY, use 'sorry' instead. 

633 

634 
* Command 'named_theorems' declares a dynamic fact within the context, 

635 
together with an attribute to maintain the content incrementally. This 

636 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

637 
of semantics due to external visual order vs. internal reverse order.

*** Document preparation *** 
698 

699 
* Document markup commands 'chapter', 'section', 'subsection', 

700 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

701 
context, even before the initial 'theory' command. Obsolete proof 

702 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

703 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

704 
instead. The old 'header' command is still retained for some time, but 

705 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

706 
update_header"). Minor INCOMPATIBILITY. 

707 

60009  708 
* Official support for "tt" style variants, via \isatt{...} or 
709 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

710 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

711 
as argument to other macros (such as footnotes). 

712 

713 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

714 
style. 

715 

716 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

717 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

718 

59951  719 
* Diagnostic commands and document markup commands within a proof do not 
720 
affect the command tag for output. Thus commands like 'thm' are subject 

721 
to proof document structure, and no longer "stick out" accidentally. 

722 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

723 
tags. Potential INCOMPATIBILITY in exotic situations. 

724 

725 
* System option "pretty_margin" is superseded by "thy_output_margin", 

726 
which is also accessible via document antiquotation option "margin". 

727 
Only the margin for document output may be changed, but not the global 

728 
pretty printing: that is 76 for plain console output, and adapted 

729 
dynamically in GUI frontends. Implementations of document 

730 
antiquotations need to observe the margin explicitly according to 

731 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

58067  857 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  858 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
859 
until applications have been ported to use the new 'smt' method. For 

860 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

861 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

862 
point to it. 

58062  863

869 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  870

* Lifting: command 'lift_definition' allows to execute lifted constants 
872 
that have as a return type a datatype containing a subtype. This 

873 
overcomes longtime limitations in the area of code generation and 

874 
lifting, and avoids tedious workarounds. 

60258  875 

60009  876

877

879 

880 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

881 

882 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

883 
nontermination in case of distributing a division. With this change 

884 
field_simps is in some cases slightly less powerful, if it fails try to 

885 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

886

888

910 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

911 

912 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

913 
that admits numeric types including nat, int, real and complex. 

914 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

915 
constraint, and the combination "real (fact k)" is likely to be 

916 
unsatisfactory. If a type conversion is still necessary, then use 

917 
"of_nat (fact k)" or "real_of_nat (fact k)".

920 
"nat o ceiling" instead. A few of the lemmas have been retained and 

921

922 
"nat_floor"/"nat_ceiling".

934 
mult_less_imp_less_left ~> mult_left_less_imp_less 

935

936 

937 
* Fact consolidation: even_less_0_iff is subsumed by 

938 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

939 

940 
* Generalized and consolidated some theorems concerning divsibility:

60009  1023 
* Subtle change of name space policy: undeclared entries are now 
1024 
considered inaccessible, instead of accessible via the fullyqualified 

1025 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1026 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1027 
contemporary applications use the strict Name_Space.check (and 
60009  1028 
derivatives) instead, which is not affected by the change. Potential 
1029 
INCOMPATIBILITY in rare applications of Name_Space.intern.

Multithreading.synchronized and its highlevel derivative

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

* Support for official Standard ML within the Isabelle context. 
1108 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1109 
Toplevel bindings are stored within the theory context; the initial 

1110 
environment is restricted to the Standard ML implementation of 

1111 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1112 
and 'SML_export' allow to exchange toplevel bindings between the two 

1113 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1114 
some examples.

1115 

57504  1116 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1117 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1118 
variable. Locale assumptions and chained facts containing "x" 

1119 
continue to be useful. The new method "hypsubst_thin" and the 

1120 
configuration option "hypsubst_thin" (within the attribute name space) 

1121 
restore the previous behavior. INCOMPATIBILITY, especially where 

1122 
induction is done after these methods or when the names of free and 

1123 
bound variables clash. As first approximation, old proofs may be 

1124 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1125 

56232  1126 
* More static checking of proof methods, which allows the system to 
1127 
form a closure over the concrete syntax. Method arguments should be 

1128 
processed in the original proof context as far as possible, before 

1129 
operating on the goal state. In any case, the standard discipline for 

1130 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1131 
number that is out of range produces an empty result sequence, not an 

1132 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1133 
proof tools. 

1134 

57452  1135 
* Lexical syntax (inner and outer) supports text cartouches with 
1136 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1137 
supports input via ` (backquote). 

1138 

1139 
* The outer syntax categories "text" (for formal comments and document 

1140 
markup commands) and "altstring" (for literal fact references) allow 

1141 
cartouches as well, in addition to the traditional mix of quotations. 

1142 

1143 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1144 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1145 
string token. General renovation of its syntax using text cartouches. 
57452  1146 
Minor INCOMPATIBILITY. 
1147 

1148 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1149 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1150 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1151 
INCOMPATIBILITY. 

1152 

1153 
* Document antiquotation @{url} produces markup for the given URL, 

1154 
which results in an active hyperlink within the text. 

1155 

1156 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1157 
not check existence within the filesystem. 

1158 

1159 
* Updated and extended manuals: codegen, datatypes, implementation, 

1160 
isarref, jedit, system.

57504  1231 
* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1232 
been discontinued to avoid the danger of nontrivial axiomatization 

1233 
that is not immediately visible. INCOMPATIBILITY, use regular 

1234 
'instance' command with proof. The required OFCLASS(...) theorem 

1235 
might be postulated via 'axiomatization' beforehand, or the proof 

1236 
finished trivially if the underlying class definition is made vacuous 

1237 
(without any assumptions). See also Isabelle/ML operations 

1238 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1239 
Axclass.arity_axiomatization. 

1240 

56245  1241 
* Basic constants of Pure use more conventional names and are always 
1242 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1243 
consequences, notably for tools in Isabelle/ML. The following 

1244 
renaming needs to be applied: 

1245 

1246 
== ~> Pure.eq 

1247 
==> ~> Pure.imp 

1248 
all ~> Pure.all 

1249 
TYPE ~> Pure.type 

1250 
dummy_pattern ~> Pure.dummy_pattern 

1251 

1252 
Systematic porting works by using the following theory setup on a 

1253 
*previous* Isabelle version to introduce the new name accesses for the 

1254 
old constants: 

1255 

1256 
setup {* 

1257 
fn thy => thy 

1258 
> Sign.root_path 

1259 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1260 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1261 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1262 
> Sign.restore_naming thy 

1263 
*} 

1264 

1265 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1266 
Later the application is moved to the current Isabelle version, and 

1267 
the auxiliary aliases are deleted.

55152  1273 
* Obsolete attribute "standard" has been discontinued (legacy since

1275 
where instantiations with schematic variables are intended (for 

1276 
declaration commands like 'lemmas' or attributes like "of"). The 

1277 
following temporary definition may help to port old applications: 

1278 

1279 
attribute_setup standard = 

1280 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

1281

* More thorough check of proof context for goal statements and 
55006  1283
