spam 5.x-3.0-beta1

The third complete rewrite of the spam module has finally entered beta status. This suggests that it is mostly feature complete, and the the underlying database schema's have stabilized. While minor features may still be added between now and the first 1.0 release, no major features should be allowed. The goal between no and the 1.0 release is to improve stability, solving any remaining bugs.

This release includes a number of new features and bug fixes since the last release.

New features:

• Custom filters: It's now possible to define custom spam filter rules, a missing feature restored from the old 5.x-1.x version of the module. Custom filter rules previously defined for the 5.x-1.x spam module will be automatically upgraded.
• Users can now automatically upgrade from the 5.x-1.x spam module by replacing their old code with the new code then running update.php.

There was an effort to better support PostgreSQL as well, though this effort is not yet complete.
