     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:
    11 
    12 * Support for nominal datatypes (binding structures) due to the
    13 HOL-Nominal logic.
    14 
    15 * General local theory infrastructure for specifications depending on
    16 parameters and assumptions (e.g. from locales, classes).
    17 
    18 * New basic specification elements 'definition', 'axiomatization',
    19 'abbreviation', 'notation'.
    20 
    21 * New version of 'inductive' package for inductive predicates;
    22 separate variant 'inductive_set'.
    23 
    24 * New 'function' package for general recursive function definitions.
    25 
    26 * New 'class' package combination of axclass + locale interpretation.
    27 
    28 * Built-in Metis prover, external linkup for automated provers, and
    29 'sledgehammer' command for automated proof synthesis.
    30 
    31 * Auto quickcheck: toplevel goals are tested for counterexamples
    32 automatically when they are stated.
    33 
    34 * Second generation code generator for a subset of HOL, targeting SML,
    35 Haskell, and OCaml.
    36 
    37 * Command 'normal_form' and method "normalization" for evaluating
    38 terms with free variables.
    39 
    40 * Full list comprehension syntax for HOL.
    41 
    42 * Much improved algebraic capabilities, including Groebner bases.
    43 
    44 * Embedding of ML code into theories with static references to the
    45 logical context (via antiquotations).
    46 
    47 * Parallel loading of theories based on native multicore support in
    48 Poly/ML 5.1.
