The ZNC bouncer project has released another version in their stable tree and is now available as version 0.080.
Despite the still low version number, ZNC sports a huge amount of useful features of which most are dynamically loadable (or unloadable) due to its modular structure.
Full SSL support, buffer playback, Twitter integration and even a Webinterface that provides full control over the bouncer are just a few of the features it comes with.
The new version has loads of minor and major bugfixes and also a few feature additions which can be found in the changelog here.
The download can be grabbed from their SourceForge project page here.
