13 
 support for userdefined Isar commands within the running session 
47158  14 
 improved support for Unicode outside original 16bit range 
15 
e.g. glyph for \<A> (thanks to jEdit 4.5.1) 

45614  16 

46485  17 
* Updated and extended reference manuals ("isarref" and 
18 
"implementation"); reduced remaining material in old "ref" manual. 

19 

45593  20 
* Rule attributes in local theory declarations (e.g. locale or class) 
21 
are now statically evaluated: the resulting theorem is stored instead 

22 
of the original expression. INCOMPATIBILITY in rare situations, where 

23 
the historic accident of dynamic reevaluation in interpretations 

24 
etc. was exploited.

37

"num_position" etc. are mainly used instead (which also include

*** HOL *** 
131 

47495  132 
* New tutorial "Programming and Proving in Isabelle/HOL" ("progprove"). 
47494  133 
It completely supercedes "A Tutorial Introduction to Structured Isar Proofs", 
134 
which has been removed. It supercedes "Isabelle/HOL, A Proof Assistant 

135 
for HigherOrder Logic" as the recommended beginners tutorial 

136 
but does not cover all of the material of that old tutorial. 

47464  137 

138 
* Discontinued old Tutorial on Isar ("isaroverview"); 

139 

140 
* Type 'a set is now a proper type constructor (just as before 

141 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

142 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

143 
sets separate, it is often sufficient to rephrase sets S accidentally 

144 
used as predicates by "%x. x : S" and predicates P accidentally used 

145 
as sets by "{x. P x}". Corresponding proofs in a first step should be 

146 
pruned from any tinkering with former theorems mem_def and Collect_def 

147 
as far as possible. 

148 

149 
For developments which deliberately mixed predicates and sets, a 

150 
planning step is necessary to determine what should become a predicate 

151 
and what a set. It can be helpful to carry out that step in 

152 
Isabelle20111 before jumping right into the current release. 

153 

154 
* The representation of numerals has changed. Datatype "num" 

155 
represents strictly positive binary numerals, along with functions 

156 
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent 

157 
positive and negated numeric literals, respectively. (See definitions 

158 
in ~~/src/HOL/Num.thy.) Potential INCOMPATIBILITY, some user theories 

159 
may require adaptations as follows:

46591  601 

45759  602 
* Quickcheck: 
47464  603 

45759  604 
 Quickcheck returns variable assignments as counterexamples, which 
605 
allows to reveal the underspecification of functions under test. 

606 
For example, refuting "hd xs = x", it presents the variable 

607 
assignment xs = [] and x = a1 as a counterexample, assuming that 

608 
any property is false whenever "hd []" occurs in it. 

47464  609 

45759  610 
These counterexample are marked as potentially spurious, as 
611 
Quickcheck also returns "xs = []" as a counterexample to the 

612 
obvious theorem "hd xs = hd xs". 

47464  613 

45759  614 
After finding a potentially spurious counterexample, Quickcheck 
615 
continues searching for genuine ones. 

47464  616 

45759  617 
By default, Quickcheck shows potentially spurious and genuine 
47464  618 
counterexamples. The option "genuine_only" sets quickcheck to only 
619 
show genuine counterexamples. 

45941  620 

621 
 The command 'quickcheck_generator' creates random and exhaustive 

622 
value generators for a given type and operations. 

47464  623 

45941  624 
It generates values by using the operations as if they were 
47463  625 
constructors of that type.

* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as 
44968  740 
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line. 
44760  741 

44777  742 
 Management of multiple theory files directly from the editor 
44760  743 
buffer store  bypassing the filesystem (no requirement to save 
744 
files for checking). 

745 

44777  746 
 Markup of formal entities within the text buffer, with semantic 
44760  747 
highlighting, tooltips and hyperlinks to jump to defining source 
748 
positions. 

749 

44777  750 
 Improved text rendering, with sub/superscripts in the source 
751 
buffer (including support for copy/paste wrt. output panel, HTML 

752 
theory output and other nonIsabelle text boxes). 

753 

754 
 Refined scheduling of proof checking and printing of results, 

44760  755 
based on interactive editor view. (Note: jEdit folding and 
756 
narrowing allows to restrict buffer perspectives explicitly.) 

757 

44777  758 
 Reduced CPU performance requirements, usable on machines with few 
44760  759 
cores. 
760 

44777  761 
 Reduced memory requirements due to pruning of unused document 
44760  762 
versions (garbage collection).

See also ~~/src/Tools/jEdit/README.html for further information, 

765 
including some remaining limitations.

768 
directory of each theory node (where the .thy file itself resides).

The global load path (such as src/HOL/Library) has been discontinued. 

770 
Note that the path element ~~ may be used to reference theories in the 

771 
Isabelle home folder  for instance, "~~/src/HOL/Library/FuncSet".

* Theory Complex_Main: The definition of infinite series was 
992 
generalized. Now it is defined on the type class {topological_space, 

993 
comm_monoid_add}. Hence it is useable also for extended real numbers. 

42484  994 

44908  995 
* Theory Complex_Main: The complex exponential function "expi" is now 
996 
a typeconstrained abbreviation for "exp :: complex => complex"; thus 

997 
several polymorphic lemmas about "exp" are now applicable to "expi". 

998 

44968  999 
* Code generation: 
1000 

1001 
 Theory Library/Code_Char_ord provides native ordering of 

1002 
characters in the target language. 

1003 

1004 
 Commands code_module and code_library are legacy, use export_code 

1005 
instead. 

1006 

1007 
 Method "evaluation" is legacy, use method "eval" instead. 

1008 

1009 
 Legacy evaluator "SML" is deactivated by default. May be 

1010 
reactivated by the following theory command: 

1011 

1012 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

1013 

1014 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

1015 

45088  1016 
* New proof method "induction" that gives induction hypotheses the 
1017 
name "IH", thus distinguishing them from further hypotheses that come 

1018 
from rule induction. The latter are still called "hyps". Method 

1019 
"induction" is a thin wrapper around "induct" and follows the same 

1020 
syntax. 

1021 

44968  1022 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
1023 
still available as a legacy feature for some time. 

1024 

1025 
* Nitpick: 

1026 
 Added "need" and "total_consts" options. 

1027 
 Reintroduced "show_skolems" option by popular demand. 

1028 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

1029 
INCOMPATIBILITY. 

1030 

1031 
* Sledgehammer: 

1032

1052 
 Introduced 'try' that not only runs 'try_methods' but also 

1053 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

1054 

1055 
* Quickcheck: 

1056 
 Added "eval" option to evaluate terms for the found counterexample 

1057 
(currently only supported by the default (exhaustive) tester). 

1058 
 Added postprocessing of terms to obtain readable counterexamples 

1059 
(currently only supported by the default (exhaustive) tester). 

1060 
 New counterexample generator quickcheck[narrowing] enables 

1061 
narrowingbased testing. Requires the Glasgow Haskell compiler 

1062 
with its installation location defined in the Isabelle settings 

1063 
environment as ISABELLE_GHC. 

1064 
 Removed quickcheck tester "SML" based on the SML code generator 

1065

1072 
Multivariate_Analysis/Extended_Real_Limits. 

1073

* Theory Library/Product_Lattice defines a pointwise ordering for the 

1085 
product type 'a * 'b, and provides instance proofs for various order 

1086 
and lattice type classes. 

1087 

1088 
* Theory Library/Countable now provides the "countable_datatype" proof 

1089 
method for proving "countable" class instances for datatypes. 

1090 

1091 
* Theory Library/Cset_Monad allows do notation for computable sets 

1092 
(cset) via the generic monad adhoc overloading facility. 

1093 

1094

1097 

1098 
 RBT is split into RBT and RBT_Mapping. 

1099 
 AssocList is split and renamed into AList and AList_Mapping.

1106 

1107 
type inat ~> type enat 

1108 
Fin ~> enat 

1109 
Infty ~> infinity (overloaded)

1114 
been renamed accordingly. INCOMPATIBILITY. 

1115 

1116 
* Session Multivariate_Analysis: The euclidean_space type class now 

1117 
fixes a constant "Basis :: 'a set" consisting of the standard 

1118 
orthonormal basis for the type. Users now have the option of 

1119 
quantifying over this set instead of using the "basis" function, e.g. 

1120 
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)". 

1121 

1122 
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed 

1123 
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants 

1124 
"Cart_nth" and "Cart_lambda" have been respectively renamed to 

1125 
"vec_nth" and "vec_lambda"; theorems mentioning those names have 

1126 
changed to match. Definition theorems for overloaded constants now use 

1127 
the standard "foo_vec_def" naming scheme. A few other theorems have 

1128 
been renamed as follows (INCOMPATIBILITY): 

1129 

1130 
Cart_eq ~> vec_eq_iff

* Discontinued support for Poly/ML 5.2, which was the last version 
1315 
without proper multithreading and TimeLimit implementation. 

1316 

1317 
* Discontinued old lib/scripts/polymlplatform, which has been 

1318 
obsolete since Isabelle20092. 

1319 

44967  1320 
* Various optional external tools are referenced more robustly and 
1321 
uniformly by explicit Isabelle settings as follows: 

1322 

1323 
ISABELLE_CSDP (formerly CSDP_EXE) 

1324 
ISABELLE_GHC (formerly EXEC_GHC or GHC_PATH) 

1325 
ISABELLE_OCAML (formerly EXEC_OCAML) 

1326 
ISABELLE_SWIPL (formerly EXEC_SWIPL) 

1327 
ISABELLE_YAP (formerly EXEC_YAP) 

1328 

1329 
Note that automated detection from the filesystem or search path has 

1330 
been discontinued. INCOMPATIBILITY.

* Scala layer provides JVM method invocation service for static 
44800  1333 
methods of type (String)String, see Invoke_Scala.method in ML. For 
1334 
example: 

43752  1335 

1336 
Invoke_Scala.method "java.lang.System.getProperty" "java.home" 

1337 

44967  1338 
Together with YXML.string_of_body/parse_body and XML.Encode/Decode 
1339 
this allows to pass structured values between ML and Scala. 

44800  1340 

44803  1341 
* The IsabelleText fonts includes some further glyphs to support the 
1342 
Prover IDE. Potential INCOMPATIBILITY: users who happen to have 

1343 
installed a local copy (which is normally *not* required) need to 

1344 
delete or update it from ~~/lib/fonts/.

* Experimental Prover IDE based on Isabelle/Scala and jEdit (see 
41612  1354 
src/Tools/jEdit). This also serves as IDE for Isabelle/ML, with 
1355 
useful tooltips and hyperlinks produced from its static analysis. The 

1356 
bundled component provides an executable Isabelle tool that can be run 

1357 
like this:

* Significantly improved Isabelle/Isar implementation manual. 
1362 

41594  1363 
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER 
41595  1364 
(and thus refers to something like $HOME/.isabelle/Isabelle2011), 
41594  1365 
while the default heap location within that directory lacks that extra 
1366 
suffix. This isolates multiple Isabelle installations from each 

1367 
other, avoiding problems with old settings in new versions.

The global load path is still partially available as legacy feature.
