The latest release of the Chatterblock plugin v3.1 is now available. The plugin will now work with Register_Globals disabled and has been tested on MySQL 5.0 (non-strict mode). There have been a few changes to support GL v1.4.1 themes and support now for SPAMX filtering of public messages as well as private messages via the /tell command.
There are no database changes so all that should be required is to replace the changed files or complete directories. Existing sites running version 3.x need to replace all the plugin files and run the plugin upgrade which just needs to update the version number.
