One of the community members on the Alliedmods forums has created a new ‘fork’ of the Sourcebans package. This forked version of SourceBans 1.5 is a modified / updated version of the original SourceBans Public Release Version 1.4.11. It adds cool features and corrects many bugs that have come up in SourceBans 1.4.11 with SourceMod and Valve game changes since 1.4.11 was released.

For more details, the download and upgrade procedure please checkout this topic on the forums.
