Subject: Announcing Isabelle2002
To: isabelle-users@cl.cam.ac.uk
Isabelle2002 is now available.
This release provides major improvements. The Isar language has
reached a mature state; the core engine is able to record full proof
terms; many aspects of the library have been reworked; several
substantial case studies have been added. Some changes may cause
incompatibility with earlier versions, but improve accessibility of
Isabelle for new users.
The most prominent highlights of Isabelle2002 are as follows (see the
NEWS of the distribution for more details).
* The Isabelle/HOL tutorial is to be published as LNCS 2283;
Isabelle2002 is the official version to go along with that book
(by Tobias Nipkow, Larry Paulson, Markus Wenzel).
* Pure: explicit proof terms for all internal inferences:
object-logics, proof tools etc. will benefit automatically
(by Stefan Berghofer).
* Pure/Isar: proper integration of the locale package for modular
theory development; additional support for rename/merge
operations, and type-inference for structured specifications
(by Markus Wenzel).
* Pure/Isar: streamlined induction proof patterns
(by Markus Wenzel).
* Pure/HOL: infrastructure for generating functional and relational
code, using the ML run-time environment (by Stefan Berghofer).
* HOL/library: numerals on all number types; several
improvements of tuple and record types; new definite description
operator; keep Hilbert's epsilon (Axiom of Choice) out of basic theories.
* HOL/Bali: large application concerning formal treatment of Java.
(by David von Oheimb and Norbert Schirmer).
* HOL/Hoare_Parallel: large application concerning verification of
parallel imperative programs (Owicki-Gries method etc.)
(by Leonor Prensa Nieto).
* HOL/GroupTheory: group theory examples including Sylow's theorem
(by Florian Kammüller).
* HOL/IMP: new proofs in Isar format
(by Gerwin Klein).
* ZF/UNITY: typeless version of Chandy and Misra's formalism
(by Sidi O Ehmety).
* System: improvements and simplifications of document preparation
(by Markus Wenzel).
* System: support for Poly/ML 4.1.1 and PolyML/4.1.2, admitting
larger heap size of applications.
* System: support for MacOS X (for Poly/ML and SML/NJ).
