* December 19, 2007
� The interpreter now allows library `case' functions.
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 now has a domain domain for representing the abstract
syntax tree of 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 support 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.
