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