41571  386 
"eq") carry proper names and are treated as default code equations.

389 
automatically derive instantiated and simplified equations for 

390 
inductive predicates, similar to 'inductive_cases'. 

391 

41571  392

393 
functorial structure of types. 

39771  394 

39644  395 
* Improved infrastructure for term evaluation using code generator 
396 
techniques, in particular static evaluation conversions. 

397 

41594  398

399 
languages. 

400 

41398  401

402

406

409

* Code generator for records: more idiomatic representation of record 
40948  415 
types. Warning: records are not covered by ancient SML code 
416 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

417 
rep_datatype declaration helps to succeed then: 

38537  418 

419 
record 'a foo = ... 

420 
... 

421 
rep_datatype foo_ext ... 

38535  422

* Records: logical foundation type for records does not carry a 
424 
'_type' suffix any longer (obsolete due to authentic syntax).

INCOMPATIBILITY. 

426 

41398  427 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  428 
testing. Random testing can be invoked by "quickcheck [random]", 
429 
exhaustive testing by "quickcheck [exhaustive]". 

41398  430 

431 
* Quickcheck instantiates polymorphic types with small finite 

432 
datatypes by default. This enables a simple execution mechanism to 

433 
handle quantifiers and function equality over the finite datatypes. 

434 

41571  435 
* Quickcheck random generator has been renamed from "code" to 
436 
"random". INCOMPATIBILITY. 

41398  437 

438 
* Quickcheck now has a configurable time limit which is set to 30 

439 
seconds by default. This can be changed by adding [timeout = n] to the 

440 
quickcheck command. The time limit for Auto Quickcheck is still set 

441 
independently. 

38461  442

444

625 

626 
Various operations from the Haskell prelude are used for generating 

627 
Haskell code. 

628 

41571  629 
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV". Term 
630 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

631 
bij_def and surj_def are unchanged. INCOMPATIBILITY. 

41398  632 

633 
* Abolished some nonalphabetic type names: "prod" and "sum" replace 

634 
"*" and "+" respectively. INCOMPATIBILITY. 

635 

636 
* Name "Plus" of disjoint sum operator "<+>" is now hidden. Write 

41571  637 
"Sum_Type.Plus" instead. 
41398  638 

639 
* Constant "split" has been merged with constant "prod_case"; names of 

640 
ML functions, facts etc. involving split have been retained so far, 

641 
though. INCOMPATIBILITY. 

642 

643 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

644 
instead. INCOMPATIBILITY. 

645 

41571  646 
* Removed lemma "Option.is_none_none" which duplicates "is_none_def". 
41398  647 
INCOMPATIBILITY. 
648 

41594  649 
* Former theory Library/Enum is now part of the HOLMain image.

659 
INCOMPATIBILITY. 

660 

661 
* Theory Library/SetsAndFunctions has been split into 

662 
Library/Function_Algebras and Library/Set_Algebras; canonical names 

663 
for instance definitions for functions; various improvements. 

664 
INCOMPATIBILITY. 

665 

666 
* Theory Library/Multiset provides stable quicksort implementation of 

667 
sort_key. 

668 

669 
* Theory Library/Multiset: renamed empty_idemp ~> empty_neutral. 

670 
INCOMPATIBILITY. 

671 

672 
* Session Multivariate_Analysis: introduced a type class for euclidean 

673 
space. Most theorems are now stated in terms of euclidean spaces 

674 
instead of finite cartesian products. 

675 

676 
types 

677 
real ^ 'n ~> 'a::real_vector 

678

_ $ _ ~> _ $$ _ 

684 
\<chi> x. _ ~> \<chi>\<chi> x. _ 

685 
CARD('n) ~> DIM('a) 

686 

687 
Also note that the indices are now natural numbers and not from some 

688 
finite type. Finite cartesian products of euclidean spaces, products 

689 
of euclidean spaces the real and complex numbers are instantiated to 

690 
be euclidean_spaces. INCOMPATIBILITY. 

691 

692 
* Session Probability: introduced pextreal as positive extended real 

693 
numbers. Use pextreal as value for measures. Introduce the 

694 
RadonNikodym derivative, product spaces and Fubini's theorem for 

695 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

696 
the integral in Multivariate Analysis. INCOMPATIBILITY. 

697 

698 
* Session Imperative_HOL: revamped, corrected dozens of inadequacies. 

699 
INCOMPATIBILITY.

702 
prove verification conditions generated by the SPARK Ada program 

703 
verifier. See also src/HOL/SPARK and src/HOL/SPARK/Examples.

720 
* The domain package now runs in definitional mode by default: The 

41571  721 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  722 
package in its original axiomatic mode, use 'domain (unsafe)'. 
723 
INCOMPATIBILITY. 

724 

41571  725 
* The new class "domain" is now the default sort. Class "predomain" 
726 
is an unpointed version of "domain". Theories can be updated by 

727 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  728 

729 
'a::type ~> 'a::countable

'a::cpo ~> 'a::predomain 

731 
'a::pcpo ~> 'a::domain 

732 

41571  733 
* The old type class "rep" has been superseded by class "domain". 
40621  734 
Accordingly, users of the definitional package must remove any 
41571  735 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  736 

41401  737 
* The domain package (definitional mode) now supports unpointed 
738 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  739 
arguments must be in class "domain".) For example, the following 
41401  740 
domain definition now works: 
741 

742 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

743 

744 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  745 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
746 
'a option, and 'a list. Additionally, it configures fixrec and the 

747 
domain package to work with these types. For example: 

41401  748 

749 
fixrec isInl :: "('a + 'b) u > tr" 

750 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

751 

752 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

753 

41571  754 
* The "(permissive)" option of fixrec has been replaced with a 
755 
perequation "(unchecked)" option. See 

756 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

757 

758 
* The "bifinite" class no longer fixes a constant "approx"; the class 

759

* The function "cprod_map" has been renamed to "prod_map". 

41401  773 
INCOMPATIBILITY. 
774 

775 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  776 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
777 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  778 

779 
* The infix syntax for binary union on each powerdomain has changed

41571  810 

811 
 Definitions of "bisim" constants no longer mention definedness. 

812 
 With mutual recursion, "bisim" predicate is now curried.

*** General *** 
971 

35436  972 
* Authentic syntax for *all* logical entities (type classes, type 
973 
constructors, term constants): provides simple and robust 

974 
correspondence between formal entities and concrete syntax. Within 

975 
the parse tree / AST representations, "constants" are decorated by 

976 
their category (class, type, const) and spelled out explicitly with 

977 
their full internal name. 

978 

979 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

980 
and translations (translation rules and translation functions in ML). 

981 
Some hints on upgrading: 

35260  982 

983 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  984 
by more modern 'type_notation', 'notation' and 'abbreviation', 
985 
which are independent of this issue. 

35260  986 

987 
 'translations' require markup within the AST; the term syntax 

988 
provides the following special forms: 

989 

990 
CONST c  produces syntax version of constant c from context 

35261  991 
XCONST c  literally c, checked as constant from context 
992 
c  literally c, if declared by 'syntax' 

993 

994 
Plain identifiers are treated as AST variables  occasionally the 

995 
system indicates accidental variables via the error "rhs contains 

996 
extra variables". 

35260  997 

35436  998 
Type classes and type constructors are marked according to their 
999 
concrete syntax. Some old translations rules need to be written 

1000 
for the "type" category, using type constructor application 

1001 
instead of pseudoterm application of the default category 

1002 
"logic". 

1003 

35260  1004 
 'parse_translation' etc. in ML may use the following 
1005 
antiquotations: 

1006 

35436  1007 
@{class_syntax c}  type class c within parse tree / AST 
1008 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  1009 
@{const_syntax c}  ML version of "CONST c" above 
1010 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

1011 

35436  1012 
 Literal types within 'typed_print_translations', i.e. those *not* 
1013 
represented as pseudoterms are represented verbatim. Use @{class 

1014 
c} or @{type_name c} here instead of the above syntax 

1015 
antiquotations. 

1016 

35260  1017 
Note that old nonauthentic syntax was based on unqualified base 
35436  1018 
names, so all of the above "constant" names would coincide. Recall 
1019 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

1020 
diagnose syntax problems.

* Command 'typedef' now works within a local theory context  without 
1117 
introducing dependencies on parameters or assumptions, which is not 

1118 
possible in Isabelle/Pure/HOL. Note that the logical environment may 

1119 
contain multiple interpretations of local typedefs (with different

nonemptiness proofs), even in a global theory context.

1122 
* New package for quotient types. Commands 'quotient_type' and 

1123 
'quotient_definition' may be used for defining types and constants by 

1124 
quotient constructions. An example is the type of integers created by 

1125 
quotienting pairs of natural numbers: 

37380  1126 

37351  1127 
fun 
37380  1128 
intrel :: "(nat * nat) => (nat * nat) => bool" 
37351  1129 
where 
1130 
"intrel (x, y) (u, v) = (x + v = u + y)" 

1131 

37380  1132 
quotient_type int = "nat * nat" / intrel 
37351  1133 
by (auto simp add: equivp_def expand_fun_eq) 
37380  1134 

37351  1135 
quotient_definition 
1136 
"0::int" is "(0::nat, 0::nat)" 

1137 

1138 
The method "lifting" can be used to lift of theorems from the 

1139 
underlying "raw" type to the quotient type. The example 

1140 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

1141 
construction and provides a reasoning infrastructure for finite sets. 

1142 

1143 
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid 

1144 
clash with new theory Quotient in Main HOL. 

1145 

1146 
* Moved the SMT binding into the main HOL session, eliminating 

1147 
separate HOLSMT session.

 Added user's manual ("isabelle doc sledgehammer"). 

1400 
 Added option syntax and "sledgehammer_params" to customize 

1401 
Sledgehammer's behavior. See the manual for details. 

1402 
 Modified the Isar proof reconstruction code so that it produces 

1403 
direct proofs rather than proofs by contradiction. (This feature 

1404 
is still experimental.)
