On the 20th of December 2007, a patch release for old 1.2 stable series was released as 1.2.3. Those running 1.2 branch and have no time or interest to upgrade to 1.3 branch (first stable release in this branch was out on the 13th of December 2007 as 1.3.0) should upgrade to 1.2.3, as it provides higher grade of stability.
The config file is full-compatible with any previous version in 1.2 branch, so the upgrade from 1.2.2 to 1.2.3 shall go smooth.
