* Toplevel theorem statements have been simplified as follows:

14 
theorems ~> lemmas 

15 
schematic_lemma ~> schematic_goal 

16 
schematic_theorem ~> schematic_goal

Commandline tool "isabelle update_theorems" updates theory sources 

20 
accordingly. 

21 

61338  22 
* 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.

72 
* There is a new short form for antiquotations with a single argument

wenzelm

73 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61501  74 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. The 
75 
standard Isabelle fonts provide glyphs to render important control 

76 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

79 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  80 
text. Commandline tool "isabelle update_cartouches t" helps to update 
81 
old sources, by approximative patching of the content of string and 

82 
cartouche tokens seen in theory sources.

88 
or terminal spaces are ignored.

61471  90 
* HTML presentation uses the standard IsabelleText font and Unicode 
91 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  92 
print mode "HTML" loses its special meaning. 
61471  93 

61463  94 
* Commands 'paragraph' and 'subparagraph' provide additional section 
95 
headings. Thus there are 6 levels of standard headings, as in HTML. 

96 

97 
* Text is structured in paragraphs and nested lists, using notation that 

98 
is similar to Markdown. The control symbols for list items are as 

99 
follows: 

100 

101 
\<^item> itemize 

102 
\<^enum> enumerate 

103 
\<^descr> description 

104 

105 
* Text may contain control symbols for markup and formatting as follows: 

61405  106 

61437  107 
\<^noindent> \noindent 
61405  108 
\<^smallskip> \smallskip 
109 
\<^medskip> \medskip 

110 
\<^bigskip> \bigskip 

111 

61463  112 
* Command 'text_raw' has been clarified: input text is processed as in 
113 
'text' (with antiquotations and control symbols). The key difference is 

114 
the lack of the surrounding isabelle markup environment in output.

140 
<proof> 

141 

60449  142 
The local assumptions are bound to the name "that". The result is 
143 
exported from context of the statement as usual. The above roughly 

60414  144 
corresponds to a raw proof block like this: 
145 

146 
{ 

147 
fix x :: 'a and y :: 'a 

60449  148 
assume that: "A x" "B y"

155 

60595  156 
* The meaning of 'show' with Pure rule statements has changed: premises 
157 
are treated in the sense of 'assume', instead of 'presume'. This means, 

158 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

159 

160 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

161 

162 
or: 

163 

164 
show "C x" if "A x" "B x" for x 

165 

166 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

167 

168 
show "C x" when "A x" "B x" for x 

169 

60406  170 
* New command 'supply' supports fact definitions during goal refinement 
171 
('apply' scripts). 

172 

60459  173 
* New command 'consider' states rules for generalized elimination and 
174 
case splitting. This is like a toplevel statement "theorem obtains" used 

175 
within a proof body; or like a multibranch 'obtain' without activation 

176 
of the local context elements yet. 

177 

60455  178 
* Proof method "cases" allows to specify the rule as first entry of 
179 
chained facts. This is particularly useful with 'consider': 

180 

181 
consider (a) A  (b) B  (c) C <proof> 

182 
then have something 

183 
proof cases 

184 
case a 

185 
then show ?thesis <proof> 

186 
next 

187 
case b 

188 
then show ?thesis <proof> 

189 
next 

190 
case c 

191 
then show ?thesis <proof> 

192 
qed 

193 

60565  194 
* Command 'case' allows fact name and attribute specification like this: 
195 

196 
case a: (c xs) 

197 
case a [attributes]: (c xs) 

198 

199 
Facts that are introduced by invoking the case context are uniformly 

200 
qualified by "a"; the same name is used for the cumulative fact. The old 

201 
form "case (c xs) [attributes]" is no longer supported. Rare 

202 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

203 
and always put attributes in front.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  240 
is marked as legacy, and will be removed eventually. The proof method 
241 
"goals" achieves a similar effect within regular Isar; often it can be 

242 
done more adequately by other means (e.g. 'consider'). 

60581  243 

60551  244 
* Nesting of Isar goal structure has been clarified: the context after 
245 
the initial backwards refinement is retained for the whole proof, within 

246 
all its context sections (as indicated via 'next'). This is e.g. 

247 
relevant for 'using', 'including', 'supply': 

248 

249

250 
supply [simp] = a

258 
occasionally useful for demonstration and testing purposes.

267

* Qualification of various formal entities in the libraries is done more 
342 
uniformly via "context begin qualified definition ... end" instead of 

343 
oldstyle "hide_const (open) ...". Consequently, both the defined

363 
and Preorder.equiv ("(_/ ~~ _)" [51, 51] 50) 

364 

61143  365 
* The alternative notation "\<Colon>" for type and sort constraints has been 
366 
removed: in LaTeX document output it looks the same as "::". 

367

*** Document preparation *** 
657 

658 
* Document markup commands 'chapter', 'section', 'subsection', 

659 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

660 
context, even before the initial 'theory' command. Obsolete proof 

661 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

662 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

663 
instead. The old 'header' command is still retained for some time, but 

664 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

665 
update_header"). Minor INCOMPATIBILITY. 

666 

60009  667 
* Official support for "tt" style variants, via \isatt{...} or 
668 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

669 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

670 
as argument to other macros (such as footnotes). 

671 

672 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

673 
style. 

674 

675 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

676 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

677 

59951  678 
* Diagnostic commands and document markup commands within a proof do not 
679 
affect the command tag for output. Thus commands like 'thm' are subject 

680 
to proof document structure, and no longer "stick out" accidentally. 

681 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

682 
tags. Potential INCOMPATIBILITY in exotic situations. 

683 

684 
* System option "pretty_margin" is superseded by "thy_output_margin", 

685 
which is also accessible via document antiquotation option "margin". 

686 
Only the margin for document output may be changed, but not the global 

687 
pretty printing: that is 76 for plain console output, and adapted 

688 
dynamically in GUI frontends. Implementations of document 

689 
antiquotations need to observe the margin explicitly according to 

690 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* The functions "sin" and "cos" are now defined for any type of sort 
864 
"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

865 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be 

866 
needed. 

867 

868 
* New library of properties of the complex transcendental functions sin, 

869 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

870 

871 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

872 
that admits numeric types including nat, int, real and complex. 

873 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

874 
constraint, and the combination "real (fact k)" is likely to be 

875 
unsatisfactory. If a type conversion is still necessary, then use 

876 
"of_nat (fact k)" or "real_of_nat (fact k)". 

877 

878 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

879 
"nat o ceiling" instead. A few of the lemmas have been retained and 

880 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

881 
"nat_floor"/"nat_ceiling". 

882 

883

893 
mult_less_imp_less_left ~> mult_left_less_imp_less 

894 
Minor INCOMPATIBILITY. 

895

897 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).

902

* Subtle change of name space policy: undeclared entries are now 
983 
considered inaccessible, instead of accessible via the fullyqualified 

984 
internal name. This mainly affects Name_Space.intern (and derivatives), 

985 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  986 
contemporary applications use the strict Name_Space.check (and 
60009  987

INCOMPATIBILITY.

Multithreading.synchronized and its highlevel derivative 

1002 
Synchronized.var (which is usually sufficient in applications). Subtle

Command 'SML_file' reads and evaluates the given Standard ML file. 

1068 
Toplevel bindings are stored within the theory context; the initial 

1069 
environment is restricted to the Standard ML implementation of 

1070 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1071

1072

1074 

57504  1075 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1076 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1077 
variable. Locale assumptions and chained facts containing "x" 

1078 
continue to be useful. The new method "hypsubst_thin" and the 

1079 
configuration option "hypsubst_thin" (within the attribute name space) 

1080 
restore the previous behavior. INCOMPATIBILITY, especially where 

1081 
induction is done after these methods or when the names of free and 

1082 
bound variables clash. As first approximation, old proofs may be 

1083 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1084 

56232  1085 
* More static checking of proof methods, which allows the system to 
1086 
form a closure over the concrete syntax. Method arguments should be 

1087 
processed in the original proof context as far as possible, before 

1088 
operating on the goal state. In any case, the standard discipline for 

1089 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1090 
number that is out of range produces an empty result sequence, not an 

1091 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1092 
proof tools. 

1093 

57452  1094 
* Lexical syntax (inner and outer) supports text cartouches with 
1095 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1096 
supports input via ` (backquote). 

1097 

1098 
* The outer syntax categories "text" (for formal comments and document 

1099 
markup commands) and "altstring" (for literal fact references) allow 

1100 
cartouches as well, in addition to the traditional mix of quotations. 

1101 

1102 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1103 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1104 
string token. General renovation of its syntax using text cartouches. 
57452  1105 
Minor INCOMPATIBILITY. 
1106 

1107 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1108 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1109 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1110 
INCOMPATIBILITY. 

1111 

1112 
* Document antiquotation @{url} produces markup for the given URL, 

1113 
which results in an active hyperlink within the text.

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1191 
been discontinued to avoid the danger of nontrivial axiomatization 

1192 
that is not immediately visible. INCOMPATIBILITY, use regular 

1193 
'instance' command with proof. The required OFCLASS(...) theorem 

1194 
might be postulated via 'axiomatization' beforehand, or the proof 

1195 
finished trivially if the underlying class definition is made vacuous 

1196 
(without any assumptions). See also Isabelle/ML operations 

1197 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1198 
Axclass.arity_axiomatization. 

1199 

56245  1200 
* Basic constants of Pure use more conventional names and are always 
1201 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1202 
consequences, notably for tools in Isabelle/ML. The following 

1203 
renaming needs to be applied: 

1204 

1205 
== ~> Pure.eq 

1206 
==> ~> Pure.imp 

1207 
all ~> Pure.all 

1208 
TYPE ~> Pure.type 

1209 
dummy_pattern ~> Pure.dummy_pattern 

1210 

1211 
Systematic porting works by using the following theory setup on a 

1212 
*previous* Isabelle version to introduce the new name accesses for the 

1213 
old constants: 

1214 

1215 
setup {* 

1216 
fn thy => thy 

1217 
> Sign.root_path 

1218 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1219 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1220 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1221 
> Sign.restore_naming thy 

1222 
*} 

1223 

1224 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1225 
Later the application is moved to the current Isabelle version, and 

1226 
the auxiliary aliases are deleted.

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

1234 
where instantiations with schematic variables are intended (for 

1235 
declaration commands like 'lemmas' or attributes like "of"). The 

1236 
following temporary definition may help to port old applications: 

1237 

1238 
attribute_setup standard = 

1239 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
