* 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

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.

* 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>".

102

103 

61595  104 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
105 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

106 
standard LaTeX macros of the same names.

109 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  110

111 
old sources, by approximative patching of the content of string and 

112 
cartouche tokens seen in theory sources.

61471  120 
* HTML presentation uses the standard IsabelleText font and Unicode 
121 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  122 
print mode "HTML" loses its special meaning. 
61471  123 

61463  124 
* Commands 'paragraph' and 'subparagraph' provide additional section 
125 
headings. Thus there are 6 levels of standard headings, as in HTML. 

126 

127 
* Text is structured in paragraphs and nested lists, using notation that 

128 
is similar to Markdown. The control symbols for list items are as 

129 
follows: 

130 

131 
\<^item> itemize 

132 
\<^enum> enumerate 

133 
\<^descr> description 

134 

135 
* Command 'text_raw' has been clarified: input text is processed as in 

136 
'text' (with antiquotations and control symbols). The key difference is 

137 
the lack of the surrounding isabelle markup environment in output.

165 
for x :: 'a and y :: 'a 

166 
<proof> 

167 

60449  168 
The local assumptions are bound to the name "that". The result is 
169 
exported from context of the statement as usual. The above roughly 

60414  170 
corresponds to a raw proof block like this: 
171 

172 
{ 

173 
fix x :: 'a and y :: 'a 

60449  174 
assume that: "A x" "B y" 
60414  175

181 

61658  182 
* Assumptions ('assume', 'presume') allow structured statements using 
183 
'if' and 'for', similar to 'have' etc. above. For example: 

184 

185 
assume result: "C x y" 

186 
if "A x" and "B y" 

187 
for x :: 'a and y :: 'a 

188 

189 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

190 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

191 

192 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

193 
only effects propositions according to actual use of variables. For 

194 
example: 

195 

196 
assume "A x" and "B y" for x and y 

197 

198 
is equivalent to: 

199 

200 
assume "\<And>x. A x" and "\<And>y. B y" 

201 

60595  202 
* The meaning of 'show' with Pure rule statements has changed: premises 
203 
are treated in the sense of 'assume', instead of 'presume'. This means, 

204 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

205 

206 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

207 

208 
or: 

209 

210 
show "C x" if "A x" "B x" for x 

211 

212 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

213 

214 
show "C x" when "A x" "B x" for x 

215 

60406  216 
* New command 'supply' supports fact definitions during goal refinement 
217 
('apply' scripts). 

218 

60459  219 
* New command 'consider' states rules for generalized elimination and 
220 
case splitting. This is like a toplevel statement "theorem obtains" used 

221 
within a proof body; or like a multibranch 'obtain' without activation 

222 
of the local context elements yet. 

223 

60455  224 
* Proof method "cases" allows to specify the rule as first entry of 
225 
chained facts. This is particularly useful with 'consider': 

226 

227 
consider (a) A  (b) B  (c) C <proof> 

228 
then have something 

229 
proof cases 

230 
case a 

231 
then show ?thesis <proof> 

232 
next 

233 
case b 

234 
then show ?thesis <proof> 

235 
next 

236 
case c 

237 
then show ?thesis <proof> 

238 
qed 

239 

60565  240 
* Command 'case' allows fact name and attribute specification like this: 
241 

242 
case a: (c xs) 

243 
case a [attributes]: (c xs) 

244 

245 
Facts that are introduced by invoking the case context are uniformly 

246 
qualified by "a"; the same name is used for the cumulative fact. The old 

247 
form "case (c xs) [attributes]" is no longer supported. Rare 

248 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

249 
and always put attributes in front.

* Command 'subgoal' allows to impose some structure on backward 
257 
refinements, to avoid proof scripts degenerating into long of 'apply' 

258

* The undocumented feature of implicit cases goal1, goal2, goal3, etc.

is marked as legacy, and will be removed eventually. The proof method 
287 
"goals" achieves a similar effect within regular Isar; often it can be

* Nesting of Isar goal structure has been clarified: the context after 
291 
the initial backwards refinement is retained for the whole proof, within 

292 
all its context sections (as indicated via 'next'). This is e.g. 

293 
relevant for 'using', 'including', 'supply':

* Command 'experiment' opens an anonymous locale context with private 
665 
naming policy. 

666 

59951  667 
* Command 'notepad' requires proper nesting of begin/end and its proof 
668 
structure in the body: 'oops' is no longer supported here. Minor 

669 
INCOMPATIBILITY, use 'sorry' instead. 

670 

671 
* Command 'named_theorems' declares a dynamic fact within the context, 

672 
together with an attribute to maintain the content incrementally. This 

673 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

674 
of semantics due to external visual order vs. internal reverse order. 

675 

676 
* 'find_theorems': search patterns which are abstractions are 

677 
schematically expanded before search. Search results match the naive 

678 
expectation more closely, particularly wrt. abbreviations.

*** Document preparation *** 
735 

736 
* Document markup commands 'chapter', 'section', 'subsection', 

737 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

738 
context, even before the initial 'theory' command. Obsolete proof 

739 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

740 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

741 
instead. The old 'header' command is still retained for some time, but 

742 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

743 
update_header"). Minor INCOMPATIBILITY. 

744 

60009  745 
* Official support for "tt" style variants, via \isatt{...} or 
746 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

747 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

748 
as argument to other macros (such as footnotes). 

749 

750 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

751 
style. 

752 

753 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

754 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

755 

59951  756 
* Diagnostic commands and document markup commands within a proof do not 
757 
affect the command tag for output. Thus commands like 'thm' are subject 

758 
to proof document structure, and no longer "stick out" accidentally. 

759 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

760 
tags. Potential INCOMPATIBILITY in exotic situations. 

761 

762 
* System option "pretty_margin" is superseded by "thy_output_margin", 

763 
which is also accessible via document antiquotation option "margin". 

764 
Only the margin for document output may be changed, but not the global 

765 
pretty printing: that is 76 for plain console output, and adapted 

766 
dynamically in GUI frontends. Implementations of document 

767 
antiquotations need to observe the margin explicitly according to 

768 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

INCOMPATIBILITY. 
58192  829 
 The "no_code" option to "free_constructors", "datatype_new", and 
830 
"codatatype" has been renamed "plugins del: code". 

831 
INCOMPATIBILITY. 

58044  832 
 The rules "set_empty" have been removed. They are easy 
833 
consequences of other set rules "by auto". 

834 
INCOMPATIBILITY. 

835 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  836 
attribute. This can influence the behavior of the "cases" proof 
837 
method when more than one case rule is applicable (e.g., an 

838 
assumption is of the form "w : set ws" and the method "cases w" 

839 
is invoked). The solution is to specify the case rule explicitly 

840 
(e.g. "cases w rule: widget.exhaust"). 

841

 Lifting and Transfer setup for basic HOL types sum and prod (also 
851 
option) is now performed by the BNF package. Theories Lifting_Sum, 

852 
Lifting_Product and Lifting_Option from Main became obsolete and 

853 
were removed. Changed definitions of the relators rel_prod and 

854 
rel_sum (using inductive). 

60111  855 
INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead 
60114  856 
of rel_prod_def and rel_sum_def. 
857 
Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names 

858

59511  882 
 CVC4 is now included with Isabelle instead of CVC3 and run by 
883

59965  884 
 Z3 is now always enabled by default, now that it is fully open

* Old and new SMT modules: 
58067  894 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  895 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
896 
until applications have been ported to use the new 'smt' method. For 

897 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

898 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

899 
point to it. 

58062  900 
INCOMPATIBILITY. 
58067  901 
 The 'smt2' method has been renamed 'smt'. 
58060  902

59569  903 
 New option 'smt_reconstruction_step_timeout' to limit the 
904 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  905 
 New option 'smt_statistics' to display statistics of the new 'smt' 
906 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  907 

60261  908 
* Lifting: command 'lift_definition' allows to execute lifted constants 
909 
that have as a return type a datatype containing a subtype. This 

910 
overcomes longtime limitations in the area of code generation and 

911 
lifting, and avoids tedious workarounds. 

60258  912 

60009  913 
* Command and antiquotation "value" provide different evaluation slots 
914 
(again), where the previous strategy (NBE after ML) serves as default. 

915 
Minor INCOMPATIBILITY. 

916 

917 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

918 

919 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

920 
nontermination in case of distributing a division. With this change 

921 
field_simps is in some cases slightly less powerful, if it fails try to 

922 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

923 

924 
* Separate class no_zero_divisors has been given up in favour of fully 

925 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY. 

926 

927 
* Class linordered_semidom really requires no zero divisors. 

928 
INCOMPATIBILITY. 

929 

930

931 
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero, 

932 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.

943 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be

947 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

948 

949 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

950 
that admits numeric types including nat, int, real and complex. 

951 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

952 
constraint, and the combination "real (fact k)" is likely to be 

953 
unsatisfactory. If a type conversion is still necessary, then use 

954 
"of_nat (fact k)" or "real_of_nat (fact k)". 

955 

956 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

957 
"nat o ceiling" instead. A few of the lemmas have been retained and 

958 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

959 
"nat_floor"/"nat_ceiling". 

960 

961

962 
type class hierarchy:

mult_less_imp_less_right ~> mult_right_less_imp_less 

971 
mult_less_imp_less_left ~> mult_left_less_imp_less 

972 
Minor INCOMPATIBILITY. 

973 

974 
* Fact consolidation: even_less_0_iff is subsumed by 

975 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

976 

977 
* Generalized and consolidated some theorems concerning divsibility: 

978 
dvd_reduce ~> dvd_add_triv_right_iff 

979 
dvd_plus_eq_right ~> dvd_add_right_iff 

980 
dvd_plus_eq_left ~> dvd_add_left_iff

* Subtle change of name space policy: undeclared entries are now 
1061 
considered inaccessible, instead of accessible via the fullyqualified 

1062 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1063 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1064 
contemporary applications use the strict Name_Space.check (and 
60009  1065 
derivatives) instead, which is not affected by the change. Potential 
1066 
INCOMPATIBILITY in rare applications of Name_Space.intern.

1146 
Toplevel bindings are stored within the theory context; the initial 

1147 
environment is restricted to the Standard ML implementation of 

1148 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1149

1150

1152 

57504  1153 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1154 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1155 
variable. Locale assumptions and chained facts containing "x" 

1156 
continue to be useful. The new method "hypsubst_thin" and the 

1157 
configuration option "hypsubst_thin" (within the attribute name space) 

1158 
restore the previous behavior. INCOMPATIBILITY, especially where 

1159 
induction is done after these methods or when the names of free and 

1160 
bound variables clash. As first approximation, old proofs may be 

1161 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1162 

56232  1163 
* More static checking of proof methods, which allows the system to 
1164 
form a closure over the concrete syntax. Method arguments should be 

1165 
processed in the original proof context as far as possible, before 

1166 
operating on the goal state. In any case, the standard discipline for 

1167 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1168 
number that is out of range produces an empty result sequence, not an 

1169 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1170 
proof tools. 

1171 

57452  1172 
* Lexical syntax (inner and outer) supports text cartouches with 
1173 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1174 
supports input via ` (backquote). 

1175 

1176 
* The outer syntax categories "text" (for formal comments and document 

1177 
markup commands) and "altstring" (for literal fact references) allow 

1178 
cartouches as well, in addition to the traditional mix of quotations. 

1179 

1180 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1181 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1182 
string token. General renovation of its syntax using text cartouches. 
57452  1183 
Minor INCOMPATIBILITY. 
1184 

1185 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1186 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1187 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1188 
INCOMPATIBILITY. 

1189 

1190 
* Document antiquotation @{url} produces markup for the given URL, 

1191 
which results in an active hyperlink within the text. 

1192 

1193 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1194 
not check existence within the filesystem.

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1269 
been discontinued to avoid the danger of nontrivial axiomatization 

1270 
that is not immediately visible. INCOMPATIBILITY, use regular 

1271 
'instance' command with proof. The required OFCLASS(...) theorem 

1272 
might be postulated via 'axiomatization' beforehand, or the proof 

1273 
finished trivially if the underlying class definition is made vacuous 

1274 
(without any assumptions). See also Isabelle/ML operations 

1275 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1276 
Axclass.arity_axiomatization. 

1277 

56245  1278 
* Basic constants of Pure use more conventional names and are always 
1279 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1280 
consequences, notably for tools in Isabelle/ML. The following 

1281 
renaming needs to be applied: 

1282 

1283 
== ~> Pure.eq 

1284 
==> ~> Pure.imp 

1285 
all ~> Pure.all 

1286 
TYPE ~> Pure.type 

1287 
dummy_pattern ~> Pure.dummy_pattern 

1288 

1289 
Systematic porting works by using the following theory setup on a 

1290 
*previous* Isabelle version to introduce the new name accesses for the 

1291 
old constants: 

1292 

1293 
setup {* 

1294 
fn thy => thy 

1295 
> Sign.root_path 

1296 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1297 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1298 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1299 
> Sign.restore_naming thy 

1300 
*} 

1301 

1302 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1303 
Later the application is moved to the current Isabelle version, and 

1304 
the auxiliary aliases are deleted.

1312 
where instantiations with schematic variables are intended (for
