OpenACS 5.9.0 Beta 2 available for testing

OpenACS 5.9.0 Beta 2 is available for testing. This release contains many changes including database changes (better performance, less space consumption), improved security (several potential XSS attacks removed) and processing speed, improved theming support, code quality, Russian localization and much more (see OpenACS 5.9 Agenda).

The tar-file release contains the OpenACS core packages. The application packages for this release can be either obtained via "install from repository" from the OpenACS site wide admin package, or from CVS on the oacs-5-9 branch. The recommended upgrade steps are described in the wiki.

OpenACS 5.9.0 should be released in about two weeks.

OpenACS 5.8.1 final released

We are proud to announce the release of OpenACS 5.8.1.
The new release differs from OpenACS 5.8.1 in the following points:
  • Compatibility of OpenACS core and 78 application packages with PostgreSQL 9.1+:
    The new version installs without any need for special parameter settings in all recent PostgreSQL versions.
  • Major cleanup: removal of calls to deprecated code, using recent Tcl byte compiled instructions rather than legacy constructs, following more closer to Postgres recommendations.
  • Functional improvements in core and application packages
  • Various performance and scalability improvements
  • Various bug fixes
  • The packages can be installed online from the OpenACS repository. The list of network-installable packages contains also DotLRN (for the full list of packages, see the full announcement).
  • Altogether, OpenACS 5.8.1 differs from OpenACS 5.7.1 in about 100,000 modifications (6145 commits) contributed by 5 committers.
Many thanks to all who helped in this effort via direct contributions, bug-reports or testing!
