RT 4.0.15 is now available.
This release fixes an important regression in the ugprade scripts
included in 4.0.14. If you attempted to upgrade from 3.8 with the RT
FAQ Manager tables (FM_*) in your database, one of the upgrade scripts
would error out.
If you were planning to upgrade from 3.8 using 4.0.14, please use 4.0.15
instead. If you have already upgraded to 4.0.14, there is no
functional change in 4.0.15.
A permanent changelog is available.
