Norbert Schirmer: record improvements;
     1 Subject: Announcing Isabelle2007

     4 Isabelle2007 is finally available.
     5 
     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).
    11 
    12 The main highlights are:
    13 
    14 * New 'function' package for general recursive function definitions.
    15 
    16 * New version of 'inductive' package for inductive predicates;
    17 separate variant 'inductive_set'.
    18 
    19 * New basic specification elements 'definition', 'axiomatization',
    20 'abbreviation', 'notation'.
    21 
    22 * New 'class' package combination of axclass + locale interpretation.
    23 
    24 * Fully featured support for nominal datatypes (binding structures)
    25 due to the HOL-Nominal logic.
    26 
    27 * Various improvements in locale infrastructure (interpretation etc.)
    28 
    29 * Various improvements of Isar language elements and related proof
    30 tools.
    31 
    32 * Built-in Metis prover, external linkup for automated provers, and
    33 'sledghammer' command for automated proof synthesis.
    34 
    35 * General local theory infrastructure for specifications depending on
    36 parameters and assumptions (e.g. from locales, classes).
    37 
    38 * Second generation code-generator for a subset of HOL, targeting SML,
    39 Haskell, and OCaml.
    40 
    41 * Improved support for arbitrary ML operations depending on the
    42 logical context.
    43 
    44 * Parallel loading of theories based on native multicore support in
    45 Poly/ML 5.1.
