     1.6  
     1.7 -* FIXME
     1.8 +* Explicit proof terms for type class reasoning.
     1.9  
    1.10 +* Authentic syntax for *all* logical entities (type classes, type
    1.11 +constructors, term constants): provides simple and robust
    1.12 +correspondence between formal entities and concrete syntax.
    1.13 +
    1.14 +* HOL: Package for constructing quotient types.
    1.15 +
    1.16 +* HOL: Code generation now with simple concept for abstract
    1.17 +datatypes obeying invariants;  applications for typical data structures
    1.18 +(e.g. search trees) can be found in the library.
    1.19 +
    1.20 +* HOL: New development of the Reals using Cauchy Sequences.
    1.21 +
    1.22 +* HOL: Reorganization of abstract algebra type class hierarchy.
    1.23 +
    1.24 +* Commands 'types', 'typedecl' and 'typedef' now work within a local theory
    1.25 +context -- without introducing dependencies on parameters or
    1.26 +assumptions.
