Subject: Announcing Isabelle2005
To: [e-mail]

Isabelle2005 is now available.

This release provides substantial advances over Isabelle2004, see the
first 1000 lines of NEWS in the distribution for more details.  Some
highlights are:

* Interpretation of locale expressions in theories, locales, and proof
contexts.

* Substantial library improvements (HOL, HOL-Complex, HOLCF).

* Proof tools for transitivity reasoning.

* General 'find_theorems' command (by term patterns, as
intro/elim/simp rules etc.).

* Commands for generating ad-hoc draft documents.

* Support for Unicode proof documents (UTF-8).

* Major internal reorganizations and performance improvements.
