* 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 

18 

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 

57 
to cursor position. Option "editor_output_state" controls implicit proof 

58 
state output in the Output panel: suppressing this reduces resource 

59 
requirements of prover time and GUI space. 

61215  60 

61483  61 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
62 
emphasized text style; the effect is visible in document output, not in 

63 
the editor. 

64 

65 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

66 
instead of former C+e LEFT.

84

85 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  86 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
87 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  88 
standard Isabelle fonts provide glyphs to render important control 
89 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

61595  91 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
92 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

93 
standard LaTeX macros of the same names.

96 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  97 
text. Commandline tool "isabelle update_cartouches t" helps to update 
98 
old sources, by approximative patching of the content of string and 

99 
cartouche tokens seen in theory sources.

105

61471  107 
* HTML presentation uses the standard IsabelleText font and Unicode 
108 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  109 
print mode "HTML" loses its special meaning. 
61471  110 

61463  111 
* Commands 'paragraph' and 'subparagraph' provide additional section 
112 
headings. Thus there are 6 levels of standard headings, as in HTML. 

113 

114 
* Text is structured in paragraphs and nested lists, using notation that 

115 
is similar to Markdown. The control symbols for list items are as 

116 
follows: 

117 

118 
\<^item> itemize 

119 
\<^enum> enumerate 

120 
\<^descr> description 

121 

122 
* Command 'text_raw' has been clarified: input text is processed as in 

123 
'text' (with antiquotations and control symbols). The key difference is 

124 
the lack of the surrounding isabelle markup environment in output.

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

153 
<proof> 

154 

60449  155 
The local assumptions are bound to the name "that". The result is 
156 
exported from context of the statement as usual. The above roughly 

60414  157 
corresponds to a raw proof block like this: 
158 

159 
{ 

160 
fix x :: 'a and y :: 'a 

60449  161 
assume that: "A x" "B y"

168 

60595  169 
* The meaning of 'show' with Pure rule statements has changed: premises 
170 
are treated in the sense of 'assume', instead of 'presume'. This means, 

171 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

172 

173 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

174 

175 
or: 

176 

177 
show "C x" if "A x" "B x" for x 

178 

179 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

180 

181 
show "C x" when "A x" "B x" for x 

182 

60406  183 
* New command 'supply' supports fact definitions during goal refinement 
184 
('apply' scripts). 

185 

60459  186 
* New command 'consider' states rules for generalized elimination and 
187 
case splitting. This is like a toplevel statement "theorem obtains" used 

188 
within a proof body; or like a multibranch 'obtain' without activation 

189 
of the local context elements yet. 

190 

60455  191 
* Proof method "cases" allows to specify the rule as first entry of 
192 
chained facts. This is particularly useful with 'consider': 

193 

194 
consider (a) A  (b) B  (c) C <proof> 

195 
then have something 

196 
proof cases 

197 
case a 

198 
then show ?thesis <proof> 

199 
next 

200 
case b 

201 
then show ?thesis <proof> 

202 
next 

203 
case c 

204 
then show ?thesis <proof> 

205 
qed 

206 

60565  207 
* Command 'case' allows fact name and attribute specification like this: 
208 

209 
case a: (c xs) 

210 
case a [attributes]: (c xs) 

211 

212 
Facts that are introduced by invoking the case context are uniformly 

213 
qualified by "a"; the same name is used for the cumulative fact. The old 

214 
form "case (c xs) [attributes]" is no longer supported. Rare 

215 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

216 
and always put attributes in front.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  253 
is marked as legacy, and will be removed eventually. The proof method 
254 
"goals" achieves a similar effect within regular Isar; often it can be 

255 
done more adequately by other means (e.g. 'consider'). 

60581  256 

60551  257 
* Nesting of Isar goal structure has been clarified: the context after 
258 
the initial backwards refinement is retained for the whole proof, within 

259 
all its context sections (as indicated via 'next'). This is e.g. 

260 
relevant for 'using', 'including', 'supply': 

261

* Command 'experiment' opens an anonymous locale context with private

620 

59951  621 
* Command 'notepad' requires proper nesting of begin/end and its proof

structure in the body: 'oops' is no longer supported here. Minor 

623 
INCOMPATIBILITY, use 'sorry' instead. 

624 

625 
* Command 'named_theorems' declares a dynamic fact within the context, 

626 
together with an attribute to maintain the content incrementally. This 

627 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

628 
of semantics due to external visual order vs. internal reverse order.

*** Document preparation *** 
689 

690 
* Document markup commands 'chapter', 'section', 'subsection', 

691 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

692 
context, even before the initial 'theory' command. Obsolete proof 

693 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

694 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

695 
instead. The old 'header' command is still retained for some time, but 

696 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

697 
update_header"). Minor INCOMPATIBILITY. 

698 

60009  699 
* Official support for "tt" style variants, via \isatt{...} or 
700 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

701 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

702 
as argument to other macros (such as footnotes). 

703 

704 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

705 
style. 

706 

707 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

708 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

709 

59951  710 
* Diagnostic commands and document markup commands within a proof do not 
711 
affect the command tag for output. Thus commands like 'thm' are subject 

712 
to proof document structure, and no longer "stick out" accidentally. 

713 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

714 
tags. Potential INCOMPATIBILITY in exotic situations. 

715 

716 
* System option "pretty_margin" is superseded by "thy_output_margin", 

717 
which is also accessible via document antiquotation option "margin". 

718 
Only the margin for document output may be changed, but not the global 

719 
pretty printing: that is 76 for plain console output, and adapted 

720 
dynamically in GUI frontends. Implementations of document 

721 
antiquotations need to observe the margin explicitly according to 

722 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

59039  831 
* Nitpick: 
60010  832 
 Fixed soundness bug related to the strict and nonstrict subset 
59039  833 
operations. 
834 

57737  835 
* Sledgehammer: 
59511  836 
 CVC4 is now included with Isabelle instead of CVC3 and run by 
837 
default. 

59965  838 
 Z3 is now always enabled by default, now that it is fully open 
839 
source. The "z3_non_commercial" option is discontinued. 

57737  840 
 Minimization is now always enabled by default. 
60010  841

59967  843 
 Proof reconstruction, both oneliners and Isar, has been 
59039  844 
dramatically improved. 
845 
 Improved support for CVC4 and veriT. 

57737  846 

58062  847 
* Old and new SMT modules: 
58067  848 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  849 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
850 
until applications have been ported to use the new 'smt' method. For 

851 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

852 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

853 
point to it. 

58062  854 
INCOMPATIBILITY. 
58067  855 
 The 'smt2' method has been renamed 'smt'. 
58060  856 
INCOMPATIBILITY. 
59569  857 
 New option 'smt_reconstruction_step_timeout' to limit the 
858 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  859 
 New option 'smt_statistics' to display statistics of the new 'smt' 
860 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  861 

60261  862 
* Lifting: command 'lift_definition' allows to execute lifted constants 
863 
that have as a return type a datatype containing a subtype. This 

864 
overcomes longtime limitations in the area of code generation and 

865 
lifting, and avoids tedious workarounds. 

60258  866 

60009  867 
* Command and antiquotation "value" provide different evaluation slots 
868 
(again), where the previous strategy (NBE after ML) serves as default. 

869 
Minor INCOMPATIBILITY. 

870 

871 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

872 

873 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

874 
nontermination in case of distributing a division. With this change 

875 
field_simps is in some cases slightly less powerful, if it fails try to 

876 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

877 

878 
* Separate class no_zero_divisors has been given up in favour of fully 

879 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY. 

880 

881 
* Class linordered_semidom really requires no zero divisors. 

882 
INCOMPATIBILITY. 

883 

884 
* Classes division_ring, field and linordered_field always demand 

885 
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero, 

886 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY. 

887

889

* The functions "sin" and "cos" are now defined for any type of sort 
896 
"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

897 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be 

898 
needed. 

899 

900 
* New library of properties of the complex transcendental functions sin, 

901 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

902 

903 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

904 
that admits numeric types including nat, int, real and complex. 

905 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

906 
constraint, and the combination "real (fact k)" is likely to be 

907 
unsatisfactory. If a type conversion is still necessary, then use 

908 
"of_nat (fact k)" or "real_of_nat (fact k)". 

909 

910 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

911 
"nat o ceiling" instead. A few of the lemmas have been retained and 

912 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

913 
"nat_floor"/"nat_ceiling". 

914 

915 
* Qualified some duplicated fact names required for boostrapping the 

916 
type class hierarchy: 

917 
ab_add_uminus_conv_diff ~> diff_conv_add_uminus 

918 
field_inverse_zero ~> inverse_zero 

919 
field_divide_inverse ~> divide_inverse 

920

* Eliminated fact duplicates: 

924 
mult_less_imp_less_right ~> mult_right_less_imp_less 

925 
mult_less_imp_less_left ~> mult_left_less_imp_less 

926 
Minor INCOMPATIBILITY. 

927 

928 
* Fact consolidation: even_less_0_iff is subsumed by 

929 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

930 

931 
* Generalized and consolidated some theorems concerning divsibility: 

932 
dvd_reduce ~> dvd_add_triv_right_iff 

933 
dvd_plus_eq_right ~> dvd_add_right_iff 

934 
dvd_plus_eq_left ~> dvd_add_left_iff 

935

58066  1012 
*** ML *** 
1013 

60009  1014 
* Subtle change of name space policy: undeclared entries are now 
1015 
considered inaccessible, instead of accessible via the fullyqualified 

1016 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1017 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1018 
contemporary applications use the strict Name_Space.check (and 
60009  1019 
derivatives) instead, which is not affected by the change. Potential 
1020 
INCOMPATIBILITY in rare applications of Name_Space.intern. 

59951  1021 

60094  1022 
* Subtle change of error semantics of Toplevel.proof_of: regular user 
1023 
ERROR instead of internal Toplevel.UNDEF. 

1024 

59951  1025 
* Basic combinators map, fold, fold_map, split_list, apply are available 
1026

1029 
INCOMPATIBILITY. 

1030 

1031 
* Former combinators NAMED_CRITICAL and CRITICAL for central critical 

1032 
sections have been discontinued, in favour of the more elementary 

1033 
Multithreading.synchronized and its highlevel derivative 

1034 
Synchronized.var (which is usually sufficient in applications). Subtle 

1035 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

1036 
nested. 

1037 

60009  1038

1106 

57504  1107 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1108 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1109 
variable. Locale assumptions and chained facts containing "x" 

1110 
continue to be useful. The new method "hypsubst_thin" and the 

1111 
configuration option "hypsubst_thin" (within the attribute name space) 

1112 
restore the previous behavior. INCOMPATIBILITY, especially where 

1113 
induction is done after these methods or when the names of free and 

1114 
bound variables clash. As first approximation, old proofs may be 

1115 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1116 

56232  1117 
* More static checking of proof methods, which allows the system to 
1118 
form a closure over the concrete syntax. Method arguments should be 

1119 
processed in the original proof context as far as possible, before 

1120 
operating on the goal state. In any case, the standard discipline for 

1121 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1122 
number that is out of range produces an empty result sequence, not an 

1123 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1124 
proof tools. 

1125 

57452  1126 
* Lexical syntax (inner and outer) supports text cartouches with 
1127 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1128 
supports input via ` (backquote). 

1129 

1130 
* The outer syntax categories "text" (for formal comments and document 

1131 
markup commands) and "altstring" (for literal fact references) allow 

1132 
cartouches as well, in addition to the traditional mix of quotations. 

1133 

1134 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1135 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1136 
string token. General renovation of its syntax using text cartouches. 
57452  1137 
Minor INCOMPATIBILITY. 
1138 

1139 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1140 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1141 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1142 
INCOMPATIBILITY. 

1143 

1144 
* Document antiquotation @{url} produces markup for the given URL, 

1145 
which results in an active hyperlink within the text. 

1146 

1147 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1148 
not check existence within the filesystem. 

1149 

1150

1151 
isarref, jedit, system.

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1223 
been discontinued to avoid the danger of nontrivial axiomatization 

1224 
that is not immediately visible. INCOMPATIBILITY, use regular 

1225 
'instance' command with proof. The required OFCLASS(...) theorem 

1226 
might be postulated via 'axiomatization' beforehand, or the proof 

1227 
finished trivially if the underlying class definition is made vacuous 

1228 
(without any assumptions). See also Isabelle/ML operations 

1229 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1230 
Axclass.arity_axiomatization. 

1231 

56245  1232 
* Basic constants of Pure use more conventional names and are always 
1233 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1234 
consequences, notably for tools in Isabelle/ML. The following 

1235 
renaming needs to be applied: 

1236 

1237 
== ~> Pure.eq 

1238 
==> ~> Pure.imp 

1239 
all ~> Pure.all 

1240 
TYPE ~> Pure.type 

1241 
dummy_pattern ~> Pure.dummy_pattern 

1242 

1243 
Systematic porting works by using the following theory setup on a 

1244 
*previous* Isabelle version to introduce the new name accesses for the 

1245 
old constants: 

1246 

1247 
setup {* 

1248 
fn thy => thy 

1249 
> Sign.root_path 

1250 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1251 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1252 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1253 
> Sign.restore_naming thy 

1254 
*} 

1255 

1256 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1257 
Later the application is moved to the current Isabelle version, and 

1258 
the auxiliary aliases are deleted.

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

1266 
where instantiations with schematic variables are intended (for 

1267 
declaration commands like 'lemmas' or attributes like "of"). The 

1268 
following temporary definition may help to port old applications:
