 more robust Sledgehammer integration (as before the sledgehammer 
12 
command line needs to be typed into the source buffer)

15 
 support for userdefined Isar commands within the running session 
47158  16 
 improved support for Unicode outside original 16bit range 
17 
e.g. glyph for \<A> (thanks to jEdit 4.5.1) 

45614  18 

46485  19 
* Updated and extended reference manuals ("isarref" and 
20 
"implementation"); reduced remaining material in old "ref" manual. 

21 

45593  22 
* Rule attributes in local theory declarations (e.g. locale or class) 
23 
are now statically evaluated: the resulting theorem is stored instead 

24 
of the original expression. INCOMPATIBILITY in rare situations, where 

25 
the historic accident of dynamic reevaluation in interpretations 

26 
etc. was exploited.

38 
xstr ~> str_token 

39

41 
"num_position" etc. are mainly used instead (which also include

* Bundled declarations associate attributed fact expressions with a

given name in the context. These may be later included in other

contexts. This allows to manage context extensions casually, without

*** HOL *** 
133 

47495  134 
* New tutorial "Programming and Proving in Isabelle/HOL" ("progprove"). 
47494  135 
It completely supercedes "A Tutorial Introduction to Structured Isar Proofs", 
136 
which has been removed. It supercedes "Isabelle/HOL, A Proof Assistant 

137 
for HigherOrder Logic" as the recommended beginners tutorial 

138 
but does not cover all of the material of that old tutorial. 

47464  139 

140 
* Discontinued old Tutorial on Isar ("isaroverview"); 

141 

142 
* Type 'a set is now a proper type constructor (just as before 

143 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

144 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

145 
sets separate, it is often sufficient to rephrase sets S accidentally 

146 
used as predicates by "%x. x : S" and predicates P accidentally used 

147 
as sets by "{x. P x}". Corresponding proofs in a first step should be 

148 
pruned from any tinkering with former theorems mem_def and Collect_def 

149 
as far as possible. 

150 

151 
For developments which deliberately mixed predicates and sets, a 

152 
planning step is necessary to determine what should become a predicate 

153 
and what a set. It can be helpful to carry out that step in 

154 
Isabelle20111 before jumping right into the current release. 

155 

156 
* The representation of numerals has changed. Datatype "num" 

157 
represents strictly positive binary numerals, along with functions 

158 
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent 

159 
positive and negated numeric literals, respectively. (See definitions 

160 
in ~~/src/HOL/Num.thy.) Potential INCOMPATIBILITY, some user theories 

161 
may require adaptations as follows:

* Session HOLProbability: Introduced the type "'a measure" to represent 

653 
measures, this replaces the records 'a algebra and 'a measure_space. The 

654 
locales based on subset_class now have two localeparameters the space 

655 
\<Omega> and the set of measurables sets M. The product of probability spaces 

656 
uses now the same constant as the finite product of sigmafinite measure 

657 
spaces "PiM :: ('i => 'a) measure". Most constants are defined now 

658 
outside of locales and gain an additional parameter, like null_sets, 

659 
almost_eventually or \<mu>'. Measure space constructions for distributions 

660 
and densities now got their own constants distr and density. Instead of 

661 
using locales to describe measure spaces with a finite space, the

measure count_space and point_measure is introduced. INCOMPATIBILITY.

* New "case_product" attribute to generate a case rule doing multiple 
825 
case distinctions at the same time. E.g. 

826 

827 
list.exhaust [case_product nat.exhaust] 

828 

829 
produces a rule which can be used to perform case distinction on both 

830 
a list and a nat. 

831 

47655  832 
* New Transfer package: 
833 

834 
 transfer_rule attribute: Maintains a collection of transfer rules, 

835 
which relate constants at two different types. Transfer rules may 

836 
relate different type instances of the same polymorphic constant, 

837 
or they may relate an operation on a raw type to a corresponding 

838 
operation on an abstract type (quotient or subtype). For example: 

839 

840 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

841 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

842 

843 
 transfer method: Replaces a subgoal on abstract types with an 

844 
equivalent subgoal on the corresponding raw types. Constants are 

845 
replaced with corresponding ones according to the transfer rules. 

846 
Goals are generalized over all free variables by default; this is 

847 
necessary for variables whose types changes, but can be overridden 

848 
for specific variables with e.g. 'transfer fixing: x y z'. 

47659  849 
The variant transfer' method allows replacing a subgoal with 
850 
one that is logically stronger (rather than equivalent). 

47655  851 

852 
 relator_eq attribute: Collects identity laws for relators of 

853 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

854 
transfer method uses these lemmas to infer transfer rules for 

855 
nonpolymorphic constants on the fly. 

856 

857 
 transfer_prover method: Assists with proving a transfer rule for a 

858 
new constant, provided the constant is defined in terms of other 

859 
constants that already have transfer rules. It should be applied 

860 
after unfolding the constant definitions. 

861 

862 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

863 
from type nat to type int. 

864 

865 
* New Lifting package: 

866 

867 
 lift_definition command: Defines operations on an abstract type in 

868 
terms of a corresponding operation on a representation type. Example 

869 
syntax: 

870 

871 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

872 
is List.insert 

873 

874 
Users must discharge a respectfulness proof obligation when each 

875 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

876 
the proof is discharged automatically.) The obligation is 

877 
presented in a userfriendly, readable form; a respectfulness 

878 
theorem in the standard format and a transfer rule are generated 

879 
by the package. 

880 

881 
 Integration with code_abstype: For typedefs (e.g. subtypes 

882 
corresponding to a datatype invariant, such as dlist), 

883 
lift_definition generates a code certificate theorem and sets up 

884 
code generation for each constant. 

885 

886 
 setup_lifting command: Sets up the Lifting package to work with 

887 
a userdefined type. The user must provide either a quotient 

888 
theorem or a type_definition theorem. The package configures 

889 
transfer rules for equality and quantifiers on the type, and sets 

890 
up the lift_definition command to work with the type. 

891 

892 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

893 
Quotient_Examples/Lift_RBT.thy, Word/Word.thy and 

894 
Library/Float.thy. 

895 

896 
* Quotient package: 

897 

898 
 The 'quotient_type' command now supports a 'morphisms' option with 

899 
rep and abs functions, similar to typedef. 

900 

901 
 'quotient_type' sets up new types to work with the Lifting and 

902 
Transfer packages, as with 'setup_lifting'. 

903 

904 
 The 'quotient_definition' command now requires the user to prove a 

905 
respectfulness property at the point where the constant is 

47659  906 
defined, similar to lift_definition; INCOMPATIBILITY. 
47655  907 

908 
 Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems 

909 
accordingly, INCOMPATIBILITY. 

910 

47464  911 
* New diagnostic command 'find_unused_assms' to find potentially 
912 
superfluous assumptions in theorems using Quickcheck. 

46591  913 

45759  914 
* Quickcheck: 
47464  915 

45759  916 
 Quickcheck returns variable assignments as counterexamples, which 
917 
allows to reveal the underspecification of functions under test. 

918 
For example, refuting "hd xs = x", it presents the variable 

919 
assignment xs = [] and x = a1 as a counterexample, assuming that 

920 
any property is false whenever "hd []" occurs in it. 

47464  921 

45759  922 
These counterexample are marked as potentially spurious, as 
923 
Quickcheck also returns "xs = []" as a counterexample to the 

924 
obvious theorem "hd xs = hd xs". 

47464  925 

45759  926 
After finding a potentially spurious counterexample, Quickcheck 
927 
continues searching for genuine ones. 

47464  928 

45759  929 
By default, Quickcheck shows potentially spurious and genuine 
47464  930 
counterexamples. The option "genuine_only" sets quickcheck to only 
931 
show genuine counterexamples. 

45941  932 

933 
 The command 'quickcheck_generator' creates random and exhaustive 

934 
value generators for a given type and operations. 

47464  935 

45941  936 
It generates values by using the operations as if they were 
47463  937 
constructors of that type. 
46170  938 

939 
 Support for multisets.

* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as

"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.

 Management of multiple theory files directly from the editor

44777  1072 
 Markup of formal entities within the text buffer, with semantic 
44760  1073 
highlighting, tooltips and hyperlinks to jump to defining source 
1074 
positions. 

1075 

44777  1076 
 Improved text rendering, with sub/superscripts in the source 
1077 
buffer (including support for copy/paste wrt. output panel, HTML 

1078 
theory output and other nonIsabelle text boxes). 

1079 

1080 
 Refined scheduling of proof checking and printing of results, 

44760  1081 
based on interactive editor view. (Note: jEdit folding and 
1082 
narrowing allows to restrict buffer perspectives explicitly.) 

1083 

44777  1084 
 Reduced CPU performance requirements, usable on machines with few 
44760  1085 
cores. 
1086 

44777  1087 
 Reduced memory requirements due to pruning of unused document 
44760  1088

1094

1095 
The global load path (such as src/HOL/Library) has been discontinued. 

1096 
Note that the path element ~~ may be used to reference theories in the 

1097 
Isabelle home folder  for instance, "~~/src/HOL/Library/FuncSet".

* Theory Complex_Main: The definition of infinite series was 
1318 
generalized. Now it is defined on the type class {topological_space, 

1319 
comm_monoid_add}. Hence it is useable also for extended real numbers. 

42484  1320 

44908  1321 
* Theory Complex_Main: The complex exponential function "expi" is now 
1322 
a typeconstrained abbreviation for "exp :: complex => complex"; thus 

1323 
several polymorphic lemmas about "exp" are now applicable to "expi". 

1324 

44968  1325 
* Code generation: 
1326 

1327 
 Theory Library/Code_Char_ord provides native ordering of 

1328 
characters in the target language. 

1329 

1330 
 Commands code_module and code_library are legacy, use export_code 

1331 
instead. 

1332 

1333 
 Method "evaluation" is legacy, use method "eval" instead. 

1334 

1335 
 Legacy evaluator "SML" is deactivated by default. May be 

1336 
reactivated by the following theory command: 

1337 

1338 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

1339 

1340 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

1341 

45088  1342 
* New proof method "induction" that gives induction hypotheses the 
1343 
name "IH", thus distinguishing them from further hypotheses that come 

1344 
from rule induction. The latter are still called "hyps". Method 

1345 
"induction" is a thin wrapper around "induct" and follows the same 

1346 
syntax. 

1347 

44968  1348 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
1349 
still available as a legacy feature for some time. 

1350 

1351 
* Nitpick: 

1352 
 Added "need" and "total_consts" options. 

1353 
 Reintroduced "show_skolems" option by popular demand. 

1354 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

1355 
INCOMPATIBILITY. 

1356 

1357 
* Sledgehammer: 

1358 
 Use quasisound (and efficient) translations by default. 

1359 
 Added support for the following provers: EToFoF, LEOII, 

1360 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

1361 
 Automatically preplay and minimize proofs before showing them if 

1362 
this can be done within reasonable time. 

1363 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

1364 
INCOMPATIBILITY. 

1365 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

1366 
"max_mono_iters", and "max_new_mono_instances" options. 

1367 
 Removed "explicit_apply" and "full_types" options as well as "Full 

1368 
Types" Proof General menu item. INCOMPATIBILITY. 

1369 

1370 
* Metis: 

1371 
 Removed "metisF"  use "metis" instead. INCOMPATIBILITY. 

1372 
 Obsoleted "metisFT"  use "metis (full_types)" instead. 

1373 
INCOMPATIBILITY. 

1374 

1375 
* Command 'try': 

1376 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

1377 
"elim:" options. INCOMPATIBILITY. 

1378 
 Introduced 'try' that not only runs 'try_methods' but also 

1379 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

1380 

1381 
* Quickcheck: 

1382 
 Added "eval" option to evaluate terms for the found counterexample 

1383 
(currently only supported by the default (exhaustive) tester). 

1384 
 Added postprocessing of terms to obtain readable counterexamples 

1385 
(currently only supported by the default (exhaustive) tester). 

1386 
 New counterexample generator quickcheck[narrowing] enables 

1387 
narrowingbased testing. Requires the Glasgow Haskell compiler 

1388 
with its installation location defined in the Isabelle settings 

1389 
environment as ISABELLE_GHC. 

1390 
 Removed quickcheck tester "SML" based on the SML code generator 

1391 
(formly in HOL/Library). 

1392 

1393 
* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

1394 
use 'partial_function' instead. 

1395 

1396 
* Theory Library/Extended_Reals replaces now the positive extended 

1397 
reals found in probability theory. This file is extended by 

1398 
Multivariate_Analysis/Extended_Real_Limits. 

1399 

44974  1400 
* Theory Library/Old_Recdef: old 'recdef' package has been moved here, 
1401 
from where it must be imported explicitly if it is really required. 

1402 
INCOMPATIBILITY. 

44968  1403 

1404 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has 

1405 
been moved here. INCOMPATIBILITY. 

1406 

1407 
* Theory Library/Saturated provides type of numbers with saturated 

1408 
arithmetic. 

1409 

1410 
* Theory Library/Product_Lattice defines a pointwise ordering for the 

1411 
product type 'a * 'b, and provides instance proofs for various order
