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
10 (mostly for HOL). Some highlights are:
12 * Support for nominal datatypes (binding structures) due to the
15 * General local theory infrastructure for specifications depending on
16 parameters and assumptions (e.g. from locales, classes).
18 * New basic specification elements 'definition', 'axiomatization',
19 'abbreviation', 'notation'.
21 * New version of 'inductive' package for inductive predicates;
22 separate variant 'inductive_set'.
24 * New 'function' package for general recursive function definitions.
26 * New 'class' package combination of axclass + locale interpretation.
28 * Built-in Metis prover, external linkup for automated provers, and
29 'sledgehammer' command for automated proof synthesis.
31 * Auto quickcheck: toplevel goals are tested for counterexamples
32 automatically when they are stated.
34 * Second generation code generator for a subset of HOL, targeting SML,
37 * Command 'normal_form' and method "normalization" for evaluating
38 terms with free variables.
40 * Full list comprehension syntax for HOL.
42 * Much improved algebraic capabilities, including Groebner bases.
44 * Embedding of ML code into theories with static references to the
45 logical context (via antiquotations).
47 * Parallel loading of theories based on native multicore support in
