4 Isabelle2007 is finally available.
6 This release introduces fundamental changes over Isabelle2005, see the
7 NEWS file in the distribution for more details. Numerous existing
8 concepts have been generalized and re-implemented based on novel
9 system architecture. New theories and proof tools have been added
12 The main highlights are:
14 * Support for nominal datatypes (binding structures) due to the
17 * General local theory infrastructure for specifications depending on
18 parameters and assumptions (e.g. from locales, classes).
20 * New basic specification elements 'definition', 'axiomatization',
21 'abbreviation', 'notation'.
23 * New version of 'inductive' package for inductive predicates;
24 separate variant 'inductive_set'.
26 * New 'function' package for general recursive function definitions.
28 * New 'class' package combination of axclass + locale interpretation.
30 * Various improvements in locale infrastructure (interpretation etc.)
32 * Various improvements of Isar language elements and related proof
35 * Built-in Metis prover, external linkup for automated provers, and
36 'sledghammer' command for automated proof synthesis.
38 * Second generation code-generator for a subset of HOL, targeting SML,
41 * Improved support for arbitrary ML operations depending on the
44 * Parallel loading of theories based on native multicore support in
47 * Improved algebraic capabilities by means of semiring normalization,
48 Groebner bases and Ferrante/Rackoff algorithm.
