14 
theorems ~> lemmas 

15 
schematic_lemma ~> schematic_goal 

16 
schematic_theorem ~> schematic_goal

Commandline tool "isabelle update_theorems" updates theory sources 

20 
accordingly.

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

60986  31 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  32 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
33 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

34 
'SML_file_no_debug' control compilation of sources with debugging 

35 
information. The Debugger panel allows to set breakpoints (via context 

36 
menu), step through stopped threads, evaluate local ML expressions etc. 

37 
At least one Debugger view needs to be active to have any effect on the 

38 
running ML program. 

39 

61173  40 
* The main Isabelle executable is managed as singleinstance Desktop 
41 
application uniformly on all platforms: Linux, Windows, Mac OS X. 

61170  42 

61198  43 
* The text overview column (status of errors, warnings etc.) is updated 
44 
asynchronously, leading to much better editor reactivity. Moreover, the 

45 
full document node content is taken into account. 

46 

61218  47 
* The State panel manages explicit proof state output, with jEdit action 
48 
"isabelle.updatestate" (shortcut S+ENTER) to trigger update according 

49 
to cursor position. Option "editor_output_state" controls implicit proof 

50 
state output in the Output panel: suppressing this reduces resource 

51 
requirements of prover time and GUI space. 

61215  52 

61483  53 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
54 
emphasized text style; the effect is visible in document output, not in 

55 
the editor. 

56 

57 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

58 
instead of former C+e LEFT.

77 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61501  78 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. The 
79 
standard Isabelle fonts provide glyphs to render important control 

80 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

86 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  87 
text. Commandline tool "isabelle update_cartouches t" helps to update 
88 
old sources, by approximative patching of the content of string and 

89 
cartouche tokens seen in theory sources.

61471  97 
* HTML presentation uses the standard IsabelleText font and Unicode 
98 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  99 
print mode "HTML" loses its special meaning. 
61471  100 

61463  101 
* Commands 'paragraph' and 'subparagraph' provide additional section 
102 
headings. Thus there are 6 levels of standard headings, as in HTML. 

103 

104 
* Text is structured in paragraphs and nested lists, using notation that 

105 
is similar to Markdown. The control symbols for list items are as 

106 
follows: 

107 

108 
\<^item> itemize 

109 
\<^enum> enumerate 

110 
\<^descr> description 

111 

112 
* Text may contain control symbols for markup and formatting as follows: 

61405  113 

61437  114 
\<^noindent> \noindent 
61405  115 
\<^smallskip> \smallskip 
116 
\<^medskip> \medskip 

117 
\<^bigskip> \bigskip 

118 

61463  119 
* Command 'text_raw' has been clarified: input text is processed as in 
120 
'text' (with antiquotations and control symbols). The key difference is 

121 
the lack of the surrounding isabelle markup environment in output.

146 
for x :: 'a and y :: 'a 

147 
<proof> 

148 

60449  149 
The local assumptions are bound to the name "that". The result is 
150 
exported from context of the statement as usual. The above roughly 

60414  151 
corresponds to a raw proof block like this: 
152 

153 
{ 

154 
fix x :: 'a and y :: 'a 

60449  155 
assume that: "A x" "B y" 
60414  156

162 

60595  163 
* The meaning of 'show' with Pure rule statements has changed: premises 
164 
are treated in the sense of 'assume', instead of 'presume'. This means, 

165 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

166 

167 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

168 

169 
or: 

170 

171 
show "C x" if "A x" "B x" for x 

172 

173 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

174 

175 
show "C x" when "A x" "B x" for x 

176 

60406  177 
* New command 'supply' supports fact definitions during goal refinement 
178 
('apply' scripts). 

179 

60459  180 
* New command 'consider' states rules for generalized elimination and 
181 
case splitting. This is like a toplevel statement "theorem obtains" used 

182 
within a proof body; or like a multibranch 'obtain' without activation 

183 
of the local context elements yet. 

184 

60455  185 
* Proof method "cases" allows to specify the rule as first entry of 
186 
chained facts. This is particularly useful with 'consider': 

187 

188 
consider (a) A  (b) B  (c) C <proof> 

189 
then have something 

190 
proof cases 

191 
case a 

192 
then show ?thesis <proof> 

193 
next 

194 
case b 

195 
then show ?thesis <proof> 

196

197 
case c 

198 
then show ?thesis <proof> 

199 
qed 

200 

60565  201 
* Command 'case' allows fact name and attribute specification like this: 
202 

203 
case a: (c xs) 

204 
case a [attributes]: (c xs) 

205 

206 
Facts that are introduced by invoking the case context are uniformly 

207 
qualified by "a"; the same name is used for the cumulative fact. The old 

208 
form "case (c xs) [attributes]" is no longer supported. Rare 

209 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

210 
and always put attributes in front.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  247 
is marked as legacy, and will be removed eventually. The proof method 
248 
"goals" achieves a similar effect within regular Isar; often it can be 

249 
done more adequately by other means (e.g. 'consider').

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

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

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

* Command 'experiment' opens an anonymous locale context with private 
601 
naming policy. 

602 

59951  603 
* Command 'notepad' requires proper nesting of begin/end and its proof 
604 
structure in the body: 'oops' is no longer supported here. Minor 

605 
INCOMPATIBILITY, use 'sorry' instead. 

606 

607 
* Command 'named_theorems' declares a dynamic fact within the context, 

608 
together with an attribute to maintain the content incrementally. This 

609 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

610 
of semantics due to external visual order vs. internal reverse order. 

611 

612 
* 'find_theorems': search patterns which are abstractions are 

613 
schematically expanded before search. Search results match the naive 

614 
expectation more closely, particularly wrt. abbreviations.

*** Document preparation *** 
671 

672 
* Document markup commands 'chapter', 'section', 'subsection', 

673 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

674 
context, even before the initial 'theory' command. Obsolete proof 

675 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

676 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

677 
instead. The old 'header' command is still retained for some time, but 

678 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

679 
update_header"). Minor INCOMPATIBILITY. 

680 

60009  681 
* Official support for "tt" style variants, via \isatt{...} or 
682 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

683 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

684 
as argument to other macros (such as footnotes). 

685 

686 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

687 
style. 

688 

689 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

690 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

691 

59951  692 
* Diagnostic commands and document markup commands within a proof do not 
693 
affect the command tag for output. Thus commands like 'thm' are subject 

694 
to proof document structure, and no longer "stick out" accidentally. 

695 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

696 
tags. Potential INCOMPATIBILITY in exotic situations. 

697 

698 
* System option "pretty_margin" is superseded by "thy_output_margin", 

699 
which is also accessible via document antiquotation option "margin". 

700 
Only the margin for document output may be changed, but not the global 

701 
pretty printing: that is 76 for plain console output, and adapted 

702 
dynamically in GUI frontends. Implementations of document 

703 
antiquotations need to observe the margin explicitly according to 

704 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* Lifting: command 'lift_definition' allows to execute lifted constants 
845 
that have as a return type a datatype containing a subtype. This 

846

884 

885 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

886 
that admits numeric types including nat, int, real and complex. 

887 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

888

* Subtle change of name space policy: undeclared entries are now 
997 
considered inaccessible, instead of accessible via the fullyqualified

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

999 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1000 
contemporary applications use the strict Name_Space.check (and

* Standard tactics and proof methods such as "clarsimp", "auto" and 
1090 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1091 
variable. Locale assumptions and chained facts containing "x" 

1092 
continue to be useful. The new method "hypsubst_thin" and the 

1093 
configuration option "hypsubst_thin" (within the attribute name space) 

1094 
restore the previous behavior. INCOMPATIBILITY, especially where 

1095 
induction is done after these methods or when the names of free and 

1096 
bound variables clash. As first approximation, old proofs may be 

1097 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1098 

56232  1099 
* More static checking of proof methods, which allows the system to 
1100 
form a closure over the concrete syntax. Method arguments should be 

1101 
processed in the original proof context as far as possible, before 

1102 
operating on the goal state. In any case, the standard discipline for 

1103 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1104 
number that is out of range produces an empty result sequence, not an 

1105 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1106 
proof tools.

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1205 
been discontinued to avoid the danger of nontrivial axiomatization 

1206 
that is not immediately visible. INCOMPATIBILITY, use regular 

1207 
'instance' command with proof. The required OFCLASS(...) theorem 

1208 
might be postulated via 'axiomatization' beforehand, or the proof 

1209 
finished trivially if the underlying class definition is made vacuous 

1210 
(without any assumptions). See also Isabelle/ML operations 

1211 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1212 
Axclass.arity_axiomatization. 

1213 

56245  1214 
* Basic constants of Pure use more conventional names and are always 
1215 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1216 
consequences, notably for tools in Isabelle/ML. The following 

1217 
renaming needs to be applied: 

1218 

1219 
== ~> Pure.eq 

1220 
==> ~> Pure.imp 

1221 
all ~> Pure.all 

1222 
TYPE ~> Pure.type 

1223 
dummy_pattern ~> Pure.dummy_pattern 

1224 

1225 
Systematic porting works by using the following theory setup on a 

1226 
*previous* Isabelle version to introduce the new name accesses for the 

1227 
old constants: 

1228 

1229 
setup {* 

1230 
fn thy => thy 

1231 
> Sign.root_path 

1232 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1233 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1234 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1235 
> Sign.restore_naming thy 

1236 
*} 

1237 

1238 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1239 
Later the application is moved to the current Isabelle version, and 

1240 
the auxiliary aliases are deleted.

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

1248 
where instantiations with schematic variables are intended (for 

1249 
declaration commands like 'lemmas' or attributes like "of"). The 

1250 
following temporary definition may help to port old applications:

attribute_setup standard =

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