 markup for bound variables 

12 
 markup for types of term variables (e.g. displayed as tooltips) 

13 

45593  14 
* Rule attributes in local theory declarations (e.g. locale or class) 
15 
are now statically evaluated: the resulting theorem is stored instead 

16 
of the original expression. INCOMPATIBILITY in rare situations, where 

17 
the historic accident of dynamic reevaluation in interpretations 

18 
etc. was exploited.

*** HOL *** 
63 

46160  64 
* Type 'a set is now a proper type constructor (just as before 
65 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

66 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

67 
sets separate, it is often sufficient to rephrase sets S accidentally 

68 
used as predicates by "%x. x : S" and predicates P accidentally used 

69 
as sets by "{x. P x}". Corresponding proofs in a first step should be 

70 
pruned from any tinkering with former theorems mem_def and 

71 
Collect_def. For developments which deliberately mixed predicates and 

72 
sets, a planning step is necessary to determine what should become a 

73 
predicate and what a set. It can be helpful to carry out that step in 

74 
Isabelle20111 before jumping right into the current release.

241 

242

* Improved code generation of multisets.

* Quickcheck: 
250 
 Quickcheck returns variable assignments as counterexamples, which 

251 
allows to reveal the underspecification of functions under test. 

252 
For example, refuting "hd xs = x", it presents the variable 

253 
assignment xs = [] and x = a1 as a counterexample, assuming that 

254 
any property is false whenever "hd []" occurs in it. 

255 
These counterexample are marked as potentially spurious, as 

256 
Quickcheck also returns "xs = []" as a counterexample to the 

257 
obvious theorem "hd xs = hd xs". 

258 
After finding a potentially spurious counterexample, Quickcheck 

259 
continues searching for genuine ones. 

260 
By default, Quickcheck shows potentially spurious and genuine 

261 
counterexamples. The option "genuine_only" sets quickcheck to 

262 
only show genuine counterexamples. 

45941  263 

264 
 The command 'quickcheck_generator' creates random and exhaustive 

265 
value generators for a given type and operations. 

266 
It generates values by using the operations as if they were 

267 
constructors of that type.

 Improved text rendering, with sub/superscripts in the source 
336 
buffer (including support for copy/paste wrt. output panel, HTML 

337 
theory output and other nonIsabelle text boxes). 

338 

339 
 Refined scheduling of proof checking and printing of results, 

44760  340 
based on interactive editor view. (Note: jEdit folding and 
341 
narrowing allows to restrict buffer perspectives explicitly.) 

342 

44777  343 
 Reduced CPU performance requirements, usable on machines with few 
44760  344 
cores. 
345 

44777  346 
 Reduced memory requirements due to pruning of unused document

44967  576 
* Theory Complex_Main: The definition of infinite series was 
577 
generalized. Now it is defined on the type class {topological_space, 

578 
comm_monoid_add}. Hence it is useable also for extended real numbers. 

42484  579 

44908  580 
* Theory Complex_Main: The complex exponential function "expi" is now 
581 
a typeconstrained abbreviation for "exp :: complex => complex"; thus 

582 
several polymorphic lemmas about "exp" are now applicable to "expi". 

583 

44968  584 
* Code generation: 
585 

586 
 Theory Library/Code_Char_ord provides native ordering of 

587 
characters in the target language. 

588 

589 
 Commands code_module and code_library are legacy, use export_code 

590 
instead. 

591 

592 
 Method "evaluation" is legacy, use method "eval" instead. 

593 

594 
 Legacy evaluator "SML" is deactivated by default. May be 

595 
reactivated by the following theory command: 

596 

597 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

598 

599 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

600 

45088  601 
* New proof method "induction" that gives induction hypotheses the 
602 
name "IH", thus distinguishing them from further hypotheses that come 

603 
from rule induction. The latter are still called "hyps". Method 

604 
"induction" is a thin wrapper around "induct" and follows the same 

605 
syntax. 

606 

44968  607 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
608 
still available as a legacy feature for some time. 

609 

610 
* Nitpick: 

611 
 Added "need" and "total_consts" options. 

612 
 Reintroduced "show_skolems" option by popular demand. 

613 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

614 
INCOMPATIBILITY. 

615 

616 
* Sledgehammer: 

617 
 Use quasisound (and efficient) translations by default. 

618 
 Added support for the following provers: EToFoF, LEOII, 

619 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

620 
 Automatically preplay and minimize proofs before showing them if 

621 
this can be done within reasonable time. 

622 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

623 
INCOMPATIBILITY. 

624 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

625 
"max_mono_iters", and "max_new_mono_instances" options. 

626 
 Removed "explicit_apply" and "full_types" options as well as "Full 

627 
Types" Proof General menu item. INCOMPATIBILITY. 

628 

629 
* Metis: 

630 
 Removed "metisF"  use "metis" instead. INCOMPATIBILITY. 

631 
 Obsoleted "metisFT"  use "metis (full_types)" instead. 

632 
INCOMPATIBILITY. 

633 

634 
* Command 'try': 

635 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

636 
"elim:" options. INCOMPATIBILITY. 

637 
 Introduced 'try' that not only runs 'try_methods' but also 

638 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

639 

640 
* Quickcheck: 

641 
 Added "eval" option to evaluate terms for the found counterexample 

642 
(currently only supported by the default (exhaustive) tester). 

643 
 Added postprocessing of terms to obtain readable counterexamples 

644 
(currently only supported by the default (exhaustive) tester). 

645 
 New counterexample generator quickcheck[narrowing] enables 

646 
narrowingbased testing. Requires the Glasgow Haskell compiler 

647 
with its installation location defined in the Isabelle settings 

648 
environment as ISABELLE_GHC. 

649 
 Removed quickcheck tester "SML" based on the SML code generator 

650 
(formly in HOL/Library). 

651 

652 
* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

653 
use 'partial_function' instead. 

654 

655 
* Theory Library/Extended_Reals replaces now the positive extended 

656 
reals found in probability theory. This file is extended by 

657 
Multivariate_Analysis/Extended_Real_Limits. 

658 

44974  659 
* Theory Library/Old_Recdef: old 'recdef' package has been moved here, 
660 
from where it must be imported explicitly if it is really required. 

661 
INCOMPATIBILITY. 

44968  662 

663 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has 

664 
been moved here. INCOMPATIBILITY. 

665 

666 
* Theory Library/Saturated provides type of numbers with saturated 

667 
arithmetic. 

668 

669 
* Theory Library/Product_Lattice defines a pointwise ordering for the 

670 
product type 'a * 'b, and provides instance proofs for various order 

671 
and lattice type classes. 

672 

673 
* Theory Library/Countable now provides the "countable_datatype" proof 

674 
method for proving "countable" class instances for datatypes. 

675 

676 
* Theory Library/Cset_Monad allows do notation for computable sets 

677 
(cset) via the generic monad adhoc overloading facility. 

678 

679 
* Library: Theories of common data structures are split into theories 

680 
for implementation, an invariantensuring type, and connection to an 

681 
abstract type. INCOMPATIBILITY. 

682 

683 
 RBT is split into RBT and RBT_Mapping. 

684 
 AssocList is split and renamed into AList and AList_Mapping. 

685 
 DList is split into DList_Impl, DList, and DList_Cset. 

686 
 Cset is split into Cset and List_Cset. 

687 

688 
* Theory Library/Nat_Infinity has been renamed to 

689 
Library/Extended_Nat, with name changes of the following types and 

690 
constants: 

691 

692 
type inat ~> type enat 

693 
Fin ~> enat 

694 
Infty ~> infinity (overloaded) 

695 
iSuc ~> eSuc 

696 
the_Fin ~> the_enat 

697 

698 
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has 

699 
been renamed accordingly. INCOMPATIBILITY. 

700 

701 
* Session Multivariate_Analysis: The euclidean_space type class now 

702 
fixes a constant "Basis :: 'a set" consisting of the standard 

703 
orthonormal basis for the type. Users now have the option of 

704 
quantifying over this set instead of using the "basis" function, e.g. 

705 
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)". 

706 

707 
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed 

708 
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants 

709 
"Cart_nth" and "Cart_lambda" have been respectively renamed to 

710 
"vec_nth" and "vec_lambda"; theorems mentioning those names have 

711 
changed to match. Definition theorems for overloaded constants now use 

712 
the standard "foo_vec_def" naming scheme. A few other theorems have 

713 
been renamed as follows (INCOMPATIBILITY): 

714 

715 
Cart_eq ~> vec_eq_iff 

716 
dist_nth_le_cart ~> dist_vec_nth_le 

717 
tendsto_vector ~> vec_tendstoI 

718 
Cauchy_vector ~> vec_CauchyI 

719 

720 
* Session Multivariate_Analysis: Several duplicate theorems have been 

721

inductive predicates, similar to 'inductive_cases'.

* Code generator for records: more idiomatic representation of record 
40948  1142 
types. Warning: records are not covered by ancient SML code 
1143 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable

1148 
rep_datatype foo_ext ...

1151 
'_type' suffix any longer (obsolete due to authentic syntax).

* Quickcheck now by default uses exhaustive testing instead of random 
41571  1155 
testing. Random testing can be invoked by "quickcheck [random]", 
1156 
exhaustive testing by "quickcheck [exhaustive]". 

41398  1157 

1158 
* Quickcheck instantiates polymorphic types with small finite 

1159 
datatypes by default. This enables a simple execution mechanism to 

1160 
handle quantifiers and function equality over the finite datatypes. 

1161 

41571  1162 
* Quickcheck random generator has been renamed from "code" to 
1163 
"random". INCOMPATIBILITY. 

41398  1164 

1165 
* Quickcheck now has a configurable time limit which is set to 30 

1166 
seconds by default. This can be changed by adding [timeout = n] to the 

1167 
quickcheck command. The time limit for Auto Quickcheck is still set 

1168

comprehensions applied to List.set to set comprehensions. Occasional 

1249 
INCOMPATIBILITY, may be deactivated like this: 

1250 

1251 
declare [[simproc del: list_to_set_comprehension]]

* Removed old version of primrec package. INCOMPATIBILITY. 
41398  1254 

1255 
* Removed simplifier congruence rule of "prod_case", as has for long 

1256 
been the case with "split". INCOMPATIBILITY.

41398  1265 

1266

1281 
* Abandoned locales equiv, congruent and congruent2 for equivalence 

1282 
relations. INCOMPATIBILITY: use equivI rather than equiv_intro (same 

1283 
for congruent(2)). 

1284 

1285 
* Some previously unqualified names have been qualified:

1349 
INCOMPATIBILITY. Note that these were not supposed to be used 

1350 
regularly unless for striking reasons; their main purpose was code 

1351 
generation. 

1352 

1353 
Various operations from the Haskell prelude are used for generating 

1354 
Haskell code. 

1355 

41571  1356 
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV". Term 
1357 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

1358 
bij_def and surj_def are unchanged. INCOMPATIBILITY. 

41398  1359 

1360 
* Abolished some nonalphabetic type names: "prod" and "sum" replace 

1361 
"*" and "+" respectively. INCOMPATIBILITY. 

1362 

1363 
* Name "Plus" of disjoint sum operator "<+>" is now hidden. Write 

41571  1364 
"Sum_Type.Plus" instead. 
41398  1365 

1366 
* Constant "split" has been merged with constant "prod_case"; names of 

1367 
ML functions, facts etc. involving split have been retained so far, 

1368 
though. INCOMPATIBILITY. 

1369 

1370 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

1371 
instead. INCOMPATIBILITY. 

1372 

41571  1373 
* Removed lemma "Option.is_none_none" which duplicates "is_none_def". 
41398  1374 
INCOMPATIBILITY. 
1375 

41594  1376 
* Former theory Library/Enum is now part of the HOLMain image. 
1377 
INCOMPATIBILITY: all constants of the Enum theory now have to be 

1378 
referred to by its qualified name. 

1379 

1380 
enum ~> Enum.enum 

1381 
nlists ~> Enum.nlists 

1382 
product ~> Enum.product 

1383 

1384 
* Theory Library/Monad_Syntax provides dosyntax for monad types. 

1385 
Syntax in Library/State_Monad has been changed to avoid ambiguities. 

1386 
INCOMPATIBILITY. 

1387 

1388 
* Theory Library/SetsAndFunctions has been split into 

1389 
Library/Function_Algebras and Library/Set_Algebras; canonical names 

1390 
for instance definitions for functions; various improvements. 

1391 
INCOMPATIBILITY. 

1392 

1393 
* Theory Library/Multiset provides stable quicksort implementation of 

1394 
sort_key. 

1395 

1396 
* Theory Library/Multiset: renamed empty_idemp ~> empty_neutral. 

1397 
INCOMPATIBILITY. 

1398 

1399 
* Session Multivariate_Analysis: introduced a type class for euclidean 

1400 
space. Most theorems are now stated in terms of euclidean spaces 

1401 
instead of finite cartesian products. 

1402 

1403 
types 

1404 
real ^ 'n ~> 'a::real_vector 

1405
