     1.9 +Isabelle2007 is finally available.

    1.11 -This release provides substantial advances over Isabelle2004, see the

    1.14 +This release introduces fundamental changes over Isabelle2005, see the
    1.15 +NEWS file in the distribution for more details.  Numerous existing
    1.16 +concepts have been generalized and re-implemented based on novel
    1.17 +system architecture.  New theories and proof tools have been added
    1.18 +(mostly for HOL).
    1.19  
    1.20 -* Interpretation of locale expressions in theories, locales, and proof
    1.21 -contexts.
    1.22 +The main highlights are:
    1.23  
    1.24 -* Substantial library improvements (HOL, HOL-Complex, HOLCF).
    1.25 +* New 'function' package for general recursive function definitions.
    1.26  
    1.27 -* Proof tools for transitivity reasoning.
    1.28 +* New version of 'inductive' package for inductive predicates;
    1.29 +separate variant 'inductive_set'.
    1.30  
    1.31 -* General 'find_theorems' command (by term patterns, as
    1.32 -intro/elim/simp rules etc.).
    1.33 +* New basic specification elements 'definition', 'axiomatization',
    1.34 +'abbreviation', 'notation'.
    1.35  
    1.36 -* Commands for generating ad-hoc draft documents.
    1.37 +* New 'class' package combination of axclass + locale interpretation.
    1.38  
    1.39 -* Support for Unicode proof documents (UTF-8).
    1.40 +* Fully featured support for nominal datatypes (binding structures)
    1.41 +due to the HOL-Nominal logic.
    1.42  
    1.43 -* Major internal reorganizations and performance improvements.
    1.44 +* Various improvements in locale infrastructure (interpretation etc.)
    1.45  
    1.46 +* Various improvements of Isar language elements and related proof
    1.47 +tools.
    1.48  
    1.49 -You may get Isabelle2005 from the following mirror sites:
    1.50 +* Built-in Metis prover, external linkup for automated provers, and
    1.51 +'sledghammer' command for automated proof synthesis.
    1.52 +
    1.53 +* General local theory infrastructure for specifications depending on
    1.54 +parameters and assumptions (e.g. from locales, classes).
    1.55 +
    1.56 +* Second generation code-generator for a subset of HOL, targeting SML,
    1.57 +Haskell, and OCaml.
    1.58 +
    1.59 +* Improved support for arbitrary ML operations depending on the
    1.60 +logical context.
    1.61 +
    1.62 +* Parallel loading of theories based on native multicore support in
    1.63 +Poly/ML 5.1.
