406 
automatically derive instantiated and simplified equations for 

407 
inductive predicates, similar to 'inductive_cases'. 

408 

41571  409

410 
functorial structure of types. 

39771  411

* Improved infrastructure for term evaluation using code generator 
413 
techniques, in particular static evaluation conversions. 

414 

41594  415 
* Code generator: Scala (2.8 or higher) has been added to the target 
416 
languages. 

417

40948  432 
types. Warning: records are not covered by ancient SML code 
433 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

434

rep_datatype foo_ext ...

441 
'_type' suffix any longer (obsolete due to authentic syntax).

41398  444 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  445 
testing. Random testing can be invoked by "quickcheck [random]", 
446 
exhaustive testing by "quickcheck [exhaustive]". 

41398  447 

448 
* Quickcheck instantiates polymorphic types with small finite 

449 
datatypes by default. This enables a simple execution mechanism to 

450 
handle quantifiers and function equality over the finite datatypes. 

451 

41571  452 
* Quickcheck random generator has been renamed from "code" to 
453 
"random". INCOMPATIBILITY. 

41398  454 

455 
* Quickcheck now has a configurable time limit which is set to 30 

456 
seconds by default. This can be changed by adding [timeout = n] to the 

457 
quickcheck command. The time limit for Auto Quickcheck is still set 

458

642 

643 
Various operations from the Haskell prelude are used for generating 

644 
Haskell code. 

645 

41571  646 
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV". Term 
647 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

648 
bij_def and surj_def are unchanged. INCOMPATIBILITY. 

41398  649 

650 
* Abolished some nonalphabetic type names: "prod" and "sum" replace 

651

41571  654 
"Sum_Type.Plus" instead. 
41398  655 

656 
* Constant "split" has been merged with constant "prod_case"; names of 

657 
ML functions, facts etc. involving split have been retained so far, 

658 
though. INCOMPATIBILITY. 

659 

660 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

661 
instead. INCOMPATIBILITY. 

662 

41571  663 
* Removed lemma "Option.is_none_none" which duplicates "is_none_def". 
41398  664 
INCOMPATIBILITY. 
665 

41594  666 
* Former theory Library/Enum is now part of the HOLMain image.

676 
INCOMPATIBILITY. 

677 

678 
* Theory Library/SetsAndFunctions has been split into 

679 
Library/Function_Algebras and Library/Set_Algebras; canonical names 

680 
for instance definitions for functions; various improvements. 

681 
INCOMPATIBILITY. 

682 

683 
* Theory Library/Multiset provides stable quicksort implementation of 

684 
sort_key. 

685 

686 
* Theory Library/Multiset: renamed empty_idemp ~> empty_neutral. 

687 
INCOMPATIBILITY. 

688 

689 
* Session Multivariate_Analysis: introduced a type class for euclidean 

690 
space. Most theorems are now stated in terms of euclidean spaces 

691 
instead of finite cartesian products. 

692 

693 
types 

694 
real ^ 'n ~> 'a::real_vector 

695 
~> 'a::euclidean_space 

696

697 
(depends on your needs)

700 
_ $ _ ~> _ $$ _ 

701 
\<chi> x. _ ~> \<chi>\<chi> x. _ 

702 
CARD('n) ~> DIM('a) 

703 

704 
Also note that the indices are now natural numbers and not from some 

705 
finite type. Finite cartesian products of euclidean spaces, products 

706 
of euclidean spaces the real and complex numbers are instantiated to 

707 
be euclidean_spaces. INCOMPATIBILITY. 

708 

709 
* Session Probability: introduced pextreal as positive extended real 

710 
numbers. Use pextreal as value for measures. Introduce the 

711 
RadonNikodym derivative, product spaces and Fubini's theorem for 

712 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

713 
the integral in Multivariate Analysis. INCOMPATIBILITY. 

714 

715 
* Session Imperative_HOL: revamped, corrected dozens of inadequacies. 

716 
INCOMPATIBILITY. 

717 

718 
* Session SPARK (with image HOLSPARK) provides commands to load and 

719 
prove verification conditions generated by the SPARK Ada program 

720 
verifier. See also src/HOL/SPARK and src/HOL/SPARK/Examples.

737 
* The domain package now runs in definitional mode by default: The 

41571  738 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  739 
package in its original axiomatic mode, use 'domain (unsafe)'. 
740 
INCOMPATIBILITY. 

741 

41571  742 
* The new class "domain" is now the default sort. Class "predomain" 
743 
is an unpointed version of "domain". Theories can be updated by 

744 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  745 

746 
'a::type ~> 'a::countable 

747 
'a::cpo ~> 'a::predomain 

748 
'a::pcpo ~> 'a::domain 

749 

41571  750 
* The old type class "rep" has been superseded by class "domain". 
40621  751 
Accordingly, users of the definitional package must remove any 
41571  752 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  753 

41401  754 
* The domain package (definitional mode) now supports unpointed 
755 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  756 
arguments must be in class "domain".) For example, the following 
41401  757 
domain definition now works: 
758 

759 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

760 

761 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  762 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
763 
'a option, and 'a list. Additionally, it configures fixrec and the 

764 
domain package to work with these types. For example: 

41401  765 

766 
fixrec isInl :: "('a + 'b) u > tr" 

767 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

768 

769 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

770 

41571  771 
* The "(permissive)" option of fixrec has been replaced with a 
772 
perequation "(unchecked)" option. See 

773 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

774 

775 
* The "bifinite" class no longer fixes a constant "approx"; the class 

776 
now just asserts that such a function exists. INCOMPATIBILITY. 

777 

778 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

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

41401  790 
INCOMPATIBILITY. 
791 

792 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  793 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
794 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  795 

796 
* The infix syntax for binary union on each powerdomain has changed

41571  827 

828 
 Definitions of "bisim" constants no longer mention definedness. 

829 
 With mutual recursion, "bisim" predicate is now curried. 

40621  830 
 With mutual recursion, each type gets a separate coind theorem. 
831 
 Variable names in bisim_def and coinduct rules have changed.

*** General ***

35436  989 
* Authentic syntax for *all* logical entities (type classes, type 
990 
constructors, term constants): provides simple and robust 

991 
correspondence between formal entities and concrete syntax. Within 

992 
the parse tree / AST representations, "constants" are decorated by 

993 
their category (class, type, const) and spelled out explicitly with 

994 
their full internal name. 

995 

996 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

997 
and translations (translation rules and translation functions in ML). 

998 
Some hints on upgrading: 

35260  999 

1000 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  1001 
by more modern 'type_notation', 'notation' and 'abbreviation', 
1002 
which are independent of this issue. 

35260  1003 

1004 
 'translations' require markup within the AST; the term syntax 

1005 
provides the following special forms: 

1006 

1007 
CONST c  produces syntax version of constant c from context 

35261  1008 
XCONST c  literally c, checked as constant from context 
1009 
c  literally c, if declared by 'syntax' 

1010 

1011 
Plain identifiers are treated as AST variables  occasionally the 

1012 
system indicates accidental variables via the error "rhs contains 

1013 
extra variables". 

35260  1014 

35436  1015 
Type classes and type constructors are marked according to their 
1016 
concrete syntax. Some old translations rules need to be written 

1017 
for the "type" category, using type constructor application 

1018 
instead of pseudoterm application of the default category 

1019 
"logic". 

1020 

35260  1021 
 'parse_translation' etc. in ML may use the following 
1022 
antiquotations: 

1023 

35436  1024 
@{class_syntax c}  type class c within parse tree / AST 
1025 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  1026 
@{const_syntax c}  ML version of "CONST c" above 
1027 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

1028 

35436  1029 
 Literal types within 'typed_print_translations', i.e. those *not* 
1030 
represented as pseudoterms are represented verbatim. Use @{class 

1031 
c} or @{type_name c} here instead of the above syntax 

1032 
antiquotations. 

1033 

35260  1034 
Note that old nonauthentic syntax was based on unqualified base 
35436  1035 
names, so all of the above "constant" names would coincide. Recall 
1036 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

1037 
diagnose syntax problems.

* Command 'typedef' now works within a local theory context  without 
1134 
introducing dependencies on parameters or assumptions, which is not

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

contain multiple interpretations of local typedefs (with different

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

1140 
'quotient_definition' may be used for defining types and constants by 

1141 
quotient constructions. An example is the type of integers created by 

1142 
quotienting pairs of natural numbers: 

37380  1143 

37351  1144 
fun 
37380  1145 
intrel :: "(nat * nat) => (nat * nat) => bool" 
37351  1146 
where 
1147 
"intrel (x, y) (u, v) = (x + v = u + y)" 

1148 

37380  1149 
quotient_type int = "nat * nat" / intrel 
37351  1150

37380  1151 

37351  1152 
quotient_definition 
1153 
"0::int" is "(0::nat, 0::nat)" 

1154 

1155 
The method "lifting" can be used to lift of theorems from the 

1156 
underlying "raw" type to the quotient type. The example 

1157 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

1158 
construction and provides a reasoning infrastructure for finite sets. 

1159 

1160 
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid 

1161 
clash with new theory Quotient in Main HOL. 

1162 

1163 
* Moved the SMT binding into the main HOL session, eliminating 

1164
