* 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'.

60986  34 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  35 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
36 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

37 
'SML_file_no_debug' control compilation of sources with debugging 

38 
information. The Debugger panel allows to set breakpoints (via context 

39 
menu), step through stopped threads, evaluate local ML expressions etc. 

40 
At least one Debugger view needs to be active to have any effect on the 

41 
running ML program. 

42 

61173  43 
* The main Isabelle executable is managed as singleinstance Desktop 
44 
application uniformly on all platforms: Linux, Windows, Mac OS X. 

61170  45 

61198  46 
* The text overview column (status of errors, warnings etc.) is updated 
47 
asynchronously, leading to much better editor reactivity. Moreover, the 

48 
full document node content is taken into account. 

49 

61218  50 
* The State panel manages explicit proof state output, with jEdit action 
51 
"isabelle.updatestate" (shortcut S+ENTER) to trigger update according 

52 
to cursor position. Option "editor_output_state" controls implicit proof 

53 
state output in the Output panel: suppressing this reduces resource 

54 
requirements of prover time and GUI space. 

61215  55 

61483  56 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
57 
emphasized text style; the effect is visible in document output, not in 

58 
the editor. 

59 

60 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

61 
instead of former C+e LEFT.

*** Document preparation *** 
65 

61471  66 
* HTML presentation uses the standard IsabelleText font and Unicode 
67 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

68 
print mode "HTML" looses its special meaning. 

69 

61463  70 
* Commands 'paragraph' and 'subparagraph' provide additional section 
71 
headings. Thus there are 6 levels of standard headings, as in HTML. 

72 

73 
* Text is structured in paragraphs and nested lists, using notation that 

74 
is similar to Markdown. The control symbols for list items are as 

75 
follows: 

76 

77 
\<^item> itemize 

78 
\<^enum> enumerate 

79 
\<^descr> description 

80 

81 
* Text may contain control symbols for markup and formatting as follows: 

61405  82 

61437  83 
\<^noindent> \noindent 
61405  84 
\<^smallskip> \smallskip 
85 
\<^medskip> \medskip 

86 
\<^bigskip> \bigskip 

87 

61463  88 
* Command 'text_raw' has been clarified: input text is processed as in 
89 
'text' (with antiquotations and control symbols). The key difference is 

90 
the lack of the surrounding isabelle markup environment in output.

109

60555

have result: "C x y"

115 
for x :: 'a and y :: 'a 

116 
<proof> 

117 

60449  118 
The local assumptions are bound to the name "that". The result is 
119 
exported from context of the statement as usual. The above roughly 

60414  120 
corresponds to a raw proof block like this: 
121 

122 
{ 

123 
fix x :: 'a and y :: 'a 

60449  124 
assume that: "A x" "B y" 
60414  125 
have "C x y" <proof> 
126 
}

131 

60595  132 
* The meaning of 'show' with Pure rule statements has changed: premises 
133 
are treated in the sense of 'assume', instead of 'presume'. This means, 

134 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

135 

136 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

137 

138 
or: 

139 

140 
show "C x" if "A x" "B x" for x 

141 

142 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

143 

144 
show "C x" when "A x" "B x" for x 

145 

60406  146 
* New command 'supply' supports fact definitions during goal refinement 
147 
('apply' scripts). 

148 

60459  149 
* New command 'consider' states rules for generalized elimination and 
150 
case splitting. This is like a toplevel statement "theorem obtains" used 

151 
within a proof body; or like a multibranch 'obtain' without activation 

152 
of the local context elements yet. 

153 

60455  154 
* Proof method "cases" allows to specify the rule as first entry of 
155 
chained facts. This is particularly useful with 'consider': 

156 

157 
consider (a) A  (b) B  (c) C <proof> 

158 
then have something 

159 
proof cases 

160 
case a 

161 
then show ?thesis <proof> 

162 
next 

163 
case b 

164 
then show ?thesis <proof> 

165 
next 

166 
case c 

167 
then show ?thesis <proof> 

168 
qed 

169 

60565  170 
* Command 'case' allows fact name and attribute specification like this: 
171 

172 
case a: (c xs) 

173 
case a [attributes]: (c xs) 

174 

175 
Facts that are introduced by invoking the case context are uniformly 

176 
qualified by "a"; the same name is used for the cumulative fact. The old 

177 
form "case (c xs) [attributes]" is no longer supported. Rare 

178 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

179 
and always put attributes in front.

* Command 'subgoal' allows to impose some structure on backward

188 
sequences. Further explanations and examples are given in the isarref 

189 
manual.

60581  215 
* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  216 
is marked as legacy, and will be removed eventually. The proof method 
217 
"goals" achieves a similar effect within regular Isar; often it can be 

218 
done more adequately by other means (e.g. 'consider'). 

60581  219 

60551  220 
* Nesting of Isar goal structure has been clarified: the context after 
221 
the initial backwards refinement is retained for the whole proof, within 

222 
all its context sections (as indicated via 'next'). This is e.g. 

223 
relevant for 'using', 'including', 'supply': 

224 

225 
have "A \<and> A" if a: A for A 

226 
supply [simp] = a

* Method "sleep" succeeds after a realtime delay (in seconds). This is 
234 
occasionally useful for demonstration and testing purposes.

* Command 'print_definitions' prints dependencies of definitional 
240 
specifications. This functionality used to be part of 'print_theory'. 

241 

60489  242 
* The vacuous fact "TERM x" may be established "by fact" or as `TERM x` 
243 
as well, not just "by this" or "." as before. 

244 

60331  245 
* Configuration option rule_insts_schematic has been discontinued 
246 
(intermediate legacy feature in Isabelle2015). INCOMPATIBILITY. 

247 

60347  248 
* Abbreviations in type classes now carry proper sort constraint. 
249 
Rare INCOMPATIBILITY in situations where the previous misbehaviour 

61228  250 
has been exploited. 
60347  251 

252 
* Refinement of userspace type system in type classes: pseudolocal 

253 
operations behave more similar to abbreviations. Potential 

254 
INCOMPATIBILITY in exotic situations.

* Qualification of various formal entities in the libraries is done more 
318 
uniformly via "context begin qualified definition ... end" instead of 

319 
oldstyle "hide_const (open) ...". Consequently, both the defined 

320 
constant and its defining fact become qualified, e.g. Option.is_none and 

321 
Option.is_none_def. Occasional INCOMPATIBILITY in applications.

339

61143  341 
* The alternative notation "\<Colon>" for type and sort constraints has been 
342 
removed: in LaTeX document output it looks the same as "::".

*** Document preparation *** 
637 

638 
* Document markup commands 'chapter', 'section', 'subsection', 

639 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

640 
context, even before the initial 'theory' command. Obsolete proof 

641 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

642 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

643 
instead. The old 'header' command is still retained for some time, but 

644 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

645 
update_header"). Minor INCOMPATIBILITY. 

646 

60009  647 
* Official support for "tt" style variants, via \isatt{...} or 
648 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

649 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

650 
as argument to other macros (such as footnotes). 

651 

652 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

653 
style. 

654 

655 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

656 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

657 

59951  658 
* Diagnostic commands and document markup commands within a proof do not 
659 
affect the command tag for output. Thus commands like 'thm' are subject 

660 
to proof document structure, and no longer "stick out" accidentally. 

661 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

662 
tags. Potential INCOMPATIBILITY in exotic situations. 

663 

664 
* System option "pretty_margin" is superseded by "thy_output_margin", 

665 
which is also accessible via document antiquotation option "margin". 

666 
Only the margin for document output may be changed, but not the global 

667 
pretty printing: that is 76 for plain console output, and adapted 

668 
dynamically in GUI frontends. Implementations of document 

669 
antiquotations need to observe the margin explicitly according to 

670 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

60009  962 
* Subtle change of name space policy: undeclared entries are now 
963 
considered inaccessible, instead of accessible via the fullyqualified 

964 
internal name. This mainly affects Name_Space.intern (and derivatives), 

965 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  966 
contemporary applications use the strict Name_Space.check (and 
60009  967

INCOMPATIBILITY in rare applications of Name_Space.intern.

977 
INCOMPATIBILITY. 

978 

979 
* Former combinators NAMED_CRITICAL and CRITICAL for central critical 

980

981 
Multithreading.synchronized and its highlevel derivative 

982 
Synchronized.var (which is usually sufficient in applications). Subtle 

983 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

984 
nested. 

985 

60009  986

* Support for official Standard ML within the Isabelle context. 
1047 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1048 
Toplevel bindings are stored within the theory context; the initial 

1049 
environment is restricted to the Standard ML implementation of 

1050 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1051 
and 'SML_export' allow to exchange toplevel bindings between the two 

1052 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1053

wenzelm

1054 

57504  1055 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1056 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1057 
variable. Locale assumptions and chained facts containing "x" 

1058 
continue to be useful. The new method "hypsubst_thin" and the 

1059 
configuration option "hypsubst_thin" (within the attribute name space) 

1060 
restore the previous behavior. INCOMPATIBILITY, especially where 

1061 
induction is done after these methods or when the names of free and 

1062 
bound variables clash. As first approximation, old proofs may be 

1063 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1064 

56232  1065 
* More static checking of proof methods, which allows the system to 
1066 
form a closure over the concrete syntax. Method arguments should be 

1067 
processed in the original proof context as far as possible, before 

1068 
operating on the goal state. In any case, the standard discipline for 

1069 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1070 
number that is out of range produces an empty result sequence, not an 

1071 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1072 
proof tools. 

1073 

57452  1074 
* Lexical syntax (inner and outer) supports text cartouches with 
1075 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1076 
supports input via ` (backquote). 

1077 

1078 
* The outer syntax categories "text" (for formal comments and document 

1079 
markup commands) and "altstring" (for literal fact references) allow 

1080 
cartouches as well, in addition to the traditional mix of quotations. 

1081 

1082 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1083 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1084 
string token. General renovation of its syntax using text cartouches. 
57452  1085 
Minor INCOMPATIBILITY. 
1086 

1087 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1088 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1089 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1090 
INCOMPATIBILITY. 

1091 

1092 
* Document antiquotation @{url} produces markup for the given URL, 

1093 
which results in an active hyperlink within the text. 

1094 

1095 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1096 
not check existence within the filesystem.

networking operations instead of jEdit virtual filesystems. 

1150

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1171 
been discontinued to avoid the danger of nontrivial axiomatization 

1172 
that is not immediately visible. INCOMPATIBILITY, use regular 

1173 
'instance' command with proof. The required OFCLASS(...) theorem 

1174 
might be postulated via 'axiomatization' beforehand, or the proof 

1175 
finished trivially if the underlying class definition is made vacuous 

1176 
(without any assumptions). See also Isabelle/ML operations 

1177 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1178 
Axclass.arity_axiomatization. 

1179 

56245  1180 
* Basic constants of Pure use more conventional names and are always 
1181 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1182 
consequences, notably for tools in Isabelle/ML. The following 

1183 
renaming needs to be applied: 

1184 

1185 
== ~> Pure.eq 

1186 
==> ~> Pure.imp 

1187 
all ~> Pure.all 

1188 
TYPE ~> Pure.type 

1189 
dummy_pattern ~> Pure.dummy_pattern 

1190 

1191 
Systematic porting works by using the following theory setup on a 

1192 
*previous* Isabelle version to introduce the new name accesses for the 

1193 
old constants: 

1194 

1195 
setup {* 

1196 
fn thy => thy 

1197 
> Sign.root_path 

1198 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1199 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1200 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1201 
> Sign.restore_naming thy 

1202 
*} 

1203 

1204 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1205 
Later the application is moved to the current Isabelle version, and 

1206 
the auxiliary aliases are deleted.

* Obsolete attribute "standard" has been discontinued (legacy since 
1213 
Isabelle2012). Potential INCOMPATIBILITY, use explicit 'for' context 

1214 
where instantiations with schematic variables are intended (for 

1215 
declaration commands like 'lemmas' or attributes like "of"). The 

1216 
following temporary definition may help to port old applications: 

1217 

1218

1219 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"

* More thorough check of proof context for goal statements and
