As previously announced, the 3.8 series of RT has now reachedend-of-life, and is no longer supported by Best Practical. This also ends support for RTFM, as well as RTIR 2.4 and 2.6, as those products depended on RT 3.8.
Best Practical continues to support the RT 4.0 (maintenance) series, as well as RT 4.2 (stable). RTFM was integrated into RT 4.0 as Articles, and is thus forward-compatible. RTIR 3.0 is available for RT 4.0, and we expect release candidates for RTIR 3.2 (compatible with RT 4.2) to be available shortly.
If you are currently still running RT 3.8 (or earlier!) and would like help with your upgrade, you can get in touch with us at firstname.lastname@example.org for professional assistance.
