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 cases/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 (by Stefan Berghofer, Larry Paulson, Markus Wenzel). * HOL/Bali: large application concerning formal treatment of Java. (by David von Oheimb and Norbert Schirmer). * HOL/HoareParallel: large application concerning verification of parallel imperative programs (Owicki-Gries method, Rely-Guarantee method, examples of garbage collection, mutual exclusion) (by Leonor Prensa Nieto). * HOL/GroupTheory: group theory examples including Sylow's theorem (by Florian Kammueller). * HOL/IMP: several new proofs in Isar format (by Gerwin Klein). * HOL/MicroJava: exception handling on the bytecode level (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; support for MacOS X (Poly/ML and SML/NJ).
