As the next major version of RT for Incident Response (RTIR) is in final testing before release, we wanted to document our plans for the current RTIR release series.
RTIR 3.0 will join RT 4.0 as our stable series and will receive regular bugfix releases. All new development will be centered on RTIR 3.2 which will be compatible with RT 4.2 (the current RT development series).
Once RT 4.2 and RTIR 3.2 are released, we expect that RTIR 2.4 and 2.6 will follow the same end-of-life schedule as RT 3.8 and the RT FAQ Manager announced here.
At this time, RTIR 2.4 and 2.6 are only receiving security or critical bugfixes, such as these patches.
If you would like to help test the next RTIR release, the third release candidate is available.
