OSSEC 2.7.1 has been released in November 2013 which contained mostly bug fixes.
Since then many new pull requests have been submitted and many developers are eager to contribute their talents. After considering many factors, it was decided that it's time to move the source code repository to GitHub. This is happening during the first quarter of 2014.
After the move, the future of OSSEC will be driven mainly by the community. There will be many opportunities for contributors/maintainers in the areas of source code, rule sets, and documentation.
Please check www.osse.net in the next few weeks for the latest development.
