Here is the relevant thread on fedora-devel-list:

Anjuta 2.26.x has already seen more than one release and the changes from 2.26.0.1 and 2.26.1.0 are not very intrusive. So although the user would not lose much if this was issued as a zero day update, it is unlikely to cause significant breakages if it is included in dist-f11.
