+* New syntax for domain package: selector names are now optional.
 Parentheses should be omitted unless argument is lazy, for example:
 
   domain 'a stream = cons "'a" (lazy "'a stream")
 
-* HOLCF: new command "fixrec" for defining recursive functions with pattern
-matching; defining multiple functions with mutual recursion is also supported.
-Patterns may include the constants cpair, spair, up, sinl, sinr, or any data
-constructor defined by the domain package. The given equations are proven as
-rewrite rules. See HOLCF/ex/Fixrec_ex.thy for syntax and examples.

-* HOLCF: new commands "cpodef" and "pcpodef" for defining predicate subtypes
-of cpo and pcpo types. Syntax is exactly like the "typedef" command, but the
-proof obligation additionally includes an admissibility requirement. The
-packages generate instances of class cpo or pcpo, with continuity and
-strictness theorems for Rep and Abs.
