Changes from previous releases are listed at http://www.open-axiom.org/1.4/ × They include significant improvements to the OpenAxiom algebra, the library compiler, and the script interpreter.

Changes from previous release, please see http://www.open-axiom.org/1.3/ * January 29, 2009. OpenAxiom 1.2.1 has been released. Changes from previous release, please see http://www.open-axiom.org/1.2/ * August 22, 2008 OpenAxiom-1.2.0 has been released. Changes from previous release, please see http://www.open-axiom.org/1.2/ * February 14, 2008 OpenAxiom-1.1.0 has been released. Changes from previous release: × OpenAxiom now supports batch processing, either for scripting or for compiling Spad libraries. × Many bugs fixes in both algebra and interpreter/compiler components. × The interpreter now allows `case' functions defined in libraries. Consequently, `case' no longer requires values of Union types, as long as the arguments are of appropriate types, e.g. ones for which a `case' operator has been defined. × OpenAxiom developers: depsys is no longer built. All files in src/interp/ are now compiled with bootsys. × OpenAxiom has a new abstract syntax tree domain for representing Spad libraries, Spad scripts, and Boot programs. Furthermore, parsers for Spad libraries and Spad scripts are now part of the standard algebra. × OpenAxiom now supports aggregates/collections of domains. More generally, it is now possible define and call functions with arguments that are of domain type. × OpenAxiom no longer uses global setting of the environment variable AXIOM. Now, OpenAxiom's AXIOMsys can be invoked with optional command line argument specifying the system root directory and the system alegbra directory. × OpenAxiom now supports versioning, meaning that installing newer versions will not overwrite previous OpenAxiom version runtimes. * September 21, 2007 OpenAxiom-1.0.1 has been released. Changes from previous release: × Now OpenAxiom ignores system-installed GCL versions that are too old. × Problem with HyperDoc not restarting fixed. × Build failure on Windows XP or Vista fixed. × Build with the dependency tarball open-axiom-1.0.x-dep.tar.bz2 has been improved. Many problems fixed. * August 24, 2007 OpenAxiom-1.0.0 has been released. * August 13, 2007 OpenAxiom has been created.
