41571  517 
"eq") carry proper names and are treated as default code equations. 
518 

41594  519 
* Inductive package: now offers command 'inductive_simps' to 
520 
automatically derive instantiated and simplified equations for 

521 
inductive predicates, similar to 'inductive_cases'. 

522 

41571  523

524 
functorial structure of types. 

39771  525

* Improved infrastructure for term evaluation using code generator 
527 
techniques, in particular static evaluation conversions. 

528 

41594  529

530 
languages. 

531

540 
combinators any longer.

* Code generator for records: more idiomatic representation of record 
40948  546 
types. Warning: records are not covered by ancient SML code 
547 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

548 
rep_datatype declaration helps to succeed then: 

38537  549 

550 
record 'a foo = ... 

551 
... 

552 
rep_datatype foo_ext ... 

38535  553 

41594  554 
* Records: logical foundation type for records does not carry a 
555 
'_type' suffix any longer (obsolete due to authentic syntax). 

556 
INCOMPATIBILITY. 

557 

41398  558 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  559 
testing. Random testing can be invoked by "quickcheck [random]", 
560 
exhaustive testing by "quickcheck [exhaustive]". 

41398  561 

562 
* Quickcheck instantiates polymorphic types with small finite 

563 
datatypes by default. This enables a simple execution mechanism to 

564 
handle quantifiers and function equality over the finite datatypes. 

565 

41571  566 
* Quickcheck random generator has been renamed from "code" to 
567 
"random". INCOMPATIBILITY. 

41398  568 

569 
* Quickcheck now has a configurable time limit which is set to 30 

570 
seconds by default. This can be changed by adding [timeout = n] to the 

571 
quickcheck command. The time limit for Auto Quickcheck is still set 

572 
independently. 

38461  573

756 

757 
Various operations from the Haskell prelude are used for generating 

758 
Haskell code. 

759 

41571  760 
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV". Term 
761 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

762 
bij_def and surj_def are unchanged. INCOMPATIBILITY. 

41398  763 

764 
* Abolished some nonalphabetic type names: "prod" and "sum" replace 

765 
"*" and "+" respectively. INCOMPATIBILITY. 

766 

767 
* Name "Plus" of disjoint sum operator "<+>" is now hidden. Write 

41571  768 
"Sum_Type.Plus" instead. 
41398  769 

770 
* Constant "split" has been merged with constant "prod_case"; names of 

771 
ML functions, facts etc. involving split have been retained so far, 

772 
though. INCOMPATIBILITY. 

773 

774 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

775 
instead. INCOMPATIBILITY. 

776 

41571  777

41398  778 
INCOMPATIBILITY. 
779 

41594  780 
* Former theory Library/Enum is now part of the HOLMain image.

790 
INCOMPATIBILITY. 

791 

792 
* Theory Library/SetsAndFunctions has been split into 

793 
Library/Function_Algebras and Library/Set_Algebras; canonical names 

794 
for instance definitions for functions; various improvements. 

795 
INCOMPATIBILITY. 

796 

797 
* Theory Library/Multiset provides stable quicksort implementation of 

798 
sort_key. 

799 

800 
* Theory Library/Multiset: renamed empty_idemp ~> empty_neutral. 

801 
INCOMPATIBILITY. 

802 

803 
* Session Multivariate_Analysis: introduced a type class for euclidean 

804 
space. Most theorems are now stated in terms of euclidean spaces 

805 
instead of finite cartesian products. 

806 

807 
types 

808 
real ^ 'n ~> 'a::real_vector 

809 
~> 'a::euclidean_space 

810

814 
_ $ _ ~> _ $$ _ 

815 
\<chi> x. _ ~> \<chi>\<chi> x. _ 

816 
CARD('n) ~> DIM('a) 

817 

818 
Also note that the indices are now natural numbers and not from some 

819 
finite type. Finite cartesian products of euclidean spaces, products 

820 
of euclidean spaces the real and complex numbers are instantiated to 

821 
be euclidean_spaces. INCOMPATIBILITY. 

822 

823 
* Session Probability: introduced pextreal as positive extended real 

824 
numbers. Use pextreal as value for measures. Introduce the 

825 
RadonNikodym derivative, product spaces and Fubini's theorem for 

826 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

827 
the integral in Multivariate Analysis. INCOMPATIBILITY. 

828 

829 
* Session Imperative_HOL: revamped, corrected dozens of inadequacies. 

830 
INCOMPATIBILITY. 

831 

832 
* Session SPARK (with image HOLSPARK) provides commands to load and 

833 
prove verification conditions generated by the SPARK Ada program 

834 
verifier. See also src/HOL/SPARK and src/HOL/SPARK/Examples.

851 
* The domain package now runs in definitional mode by default: The 

41571  852 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  853 
package in its original axiomatic mode, use 'domain (unsafe)'. 
854 
INCOMPATIBILITY. 

855 

41571  856 
* The new class "domain" is now the default sort. Class "predomain" 
857 
is an unpointed version of "domain". Theories can be updated by 

858 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  859 

860 
'a::type ~> 'a::countable 

861 
'a::cpo ~> 'a::predomain 

862 
'a::pcpo ~> 'a::domain 

863 

41571  864 
* The old type class "rep" has been superseded by class "domain". 
40621  865 
Accordingly, users of the definitional package must remove any 
41571  866 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  867 

41401  868 
* The domain package (definitional mode) now supports unpointed 
869 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  870 
arguments must be in class "domain".) For example, the following 
41401  871 
domain definition now works: 
872 

873 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

874 

875 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  876 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
877 
'a option, and 'a list. Additionally, it configures fixrec and the 

878 
domain package to work with these types. For example: 

41401  879 

880 
fixrec isInl :: "('a + 'b) u > tr" 

881 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

882 

883 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

884 

41571  885 
* The "(permissive)" option of fixrec has been replaced with a 
886 
perequation "(unchecked)" option. See 

887 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

888 

889 
* The "bifinite" class no longer fixes a constant "approx"; the class 

890 
now just asserts that such a function exists. INCOMPATIBILITY. 

891 

892 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

903 
* The function "cprod_map" has been renamed to "prod_map". 

41401  904 
INCOMPATIBILITY. 
905 

906 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  907 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
908 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  909 

910 
* The infix syntax for binary union on each powerdomain has changed

from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set

41571  941 

942 
 Definitions of "bisim" constants no longer mention definedness. 

943 
 With mutual recursion, "bisim" predicate is now curried. 

40621  944 
 With mutual recursion, each type gets a separate coind theorem. 
945 
 Variable names in bisim_def and coinduct rules have changed.

*** General *** 
1102 

35436  1103 
* Authentic syntax for *all* logical entities (type classes, type 
1104 
constructors, term constants): provides simple and robust 

1105 
correspondence between formal entities and concrete syntax. Within 

1106 
the parse tree / AST representations, "constants" are decorated by 

1107 
their category (class, type, const) and spelled out explicitly with 

1108 
their full internal name. 

1109 

1110 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

1111 
and translations (translation rules and translation functions in ML). 

1112 
Some hints on upgrading: 

35260  1113 

1114 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  1115 
by more modern 'type_notation', 'notation' and 'abbreviation', 
1116 
which are independent of this issue. 

35260  1117 

1118 
 'translations' require markup within the AST; the term syntax 

1119 
provides the following special forms: 

1120 

1121 
CONST c  produces syntax version of constant c from context 

35261  1122 
XCONST c  literally c, checked as constant from context 
1123 
c  literally c, if declared by 'syntax' 

1124 

1125 
Plain identifiers are treated as AST variables  occasionally the 

1126 
system indicates accidental variables via the error "rhs contains 

1127 
extra variables". 

35260  1128 

35436  1129 
Type classes and type constructors are marked according to their 
1130 
concrete syntax. Some old translations rules need to be written 

1131 
for the "type" category, using type constructor application 

1132 
instead of pseudoterm application of the default category 

1133 
"logic". 

1134 

35260  1135 
 'parse_translation' etc. in ML may use the following 
1136 
antiquotations: 

1137 

35436  1138 
@{class_syntax c}  type class c within parse tree / AST 
1139 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  1140 
@{const_syntax c}  ML version of "CONST c" above 
1141 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

1142 

35436  1143 
 Literal types within 'typed_print_translations', i.e. those *not* 
1144 
represented as pseudoterms are represented verbatim. Use @{class 

1145 
c} or @{type_name c} here instead of the above syntax 

1146 
antiquotations. 

1147 

35260  1148 
Note that old nonauthentic syntax was based on unqualified base 
35436  1149 
names, so all of the above "constant" names would coincide. Recall 
1150 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

1151 
diagnose syntax problems.

* Command 'typedef' now works within a local theory context  without 
1248 
introducing dependencies on parameters or assumptions, which is not 

1249 
possible in Isabelle/Pure/HOL. Note that the logical environment may 

1250 
contain multiple interpretations of local typedefs (with different 

1251 
nonemptiness proofs), even in a global theory context. 

1252 

1253 
* New package for quotient types. Commands 'quotient_type' and 

1254 
'quotient_definition' may be used for defining types and constants by 

1255 
quotient constructions. An example is the type of integers created by 

1256 
quotienting pairs of natural numbers: 

37380  1257 

37351  1258 
fun 
37380  1259 
intrel :: "(nat * nat) => (nat * nat) => bool" 
37351  1260 
where 
1261 
"intrel (x, y) (u, v) = (x + v = u + y)" 

1262 

37380  1263 
quotient_type int = "nat * nat" / intrel 
37351  1264 
by (auto simp add: equivp_def expand_fun_eq) 
37380  1265 

37351  1266 
quotient_definition 
1267 
"0::int" is "(0::nat, 0::nat)" 

1268 

1269 
The method "lifting" can be used to lift of theorems from the 

1270 
underlying "raw" type to the quotient type. The example 

1271 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

1272 
construction and provides a reasoning infrastructure for finite sets. 

1273 

1274 
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid 

1275 
clash with new theory Quotient in Main HOL. 

1276 

1277 
* Moved the SMT binding into the main HOL session, eliminating 

1278 
separate HOLSMT session.
