It seems I often see garbage in the release notes from the previous release notes. From my explanation on irc:

10:01:18 PM) LetoTo: anyone else has seen mangling of notes?
(10:01:20 PM) LetoTo: Notes: Remove cronjob, enable zonefiles-write: in nsd.conf, don't delete
(10:01:20 PM) LetoTo: : xfrd.state ---- Improved integration for systemd,
(10:01:20 PM) LetoTo: : use PrivateTmp
(10:01:34 PM) LetoTo: everything after the ---- is from the previous update
(10:02:27 PM) LetoTo: double checking fedora update for 22 now. submitting with:
(10:02:29 PM) LetoTo: notes=Remove cronjob, enable zonefiles-write: in nsd.conf, don't delete \
(10:02:29 PM) LetoTo: xfrd.state
(10:02:48 PM) LetoTo: Notes: Remove cronjob, enable zonefiles-write: in nsd.conf, don't delete \
(10:02:48 PM) LetoTo: : xfrd.state ---- Improved integration for systemd,
(10:02:48 PM) LetoTo: : use PrivateTmp
(10:02:57 PM) LetoTo: yeah. it's not me :P

This happened again with my latest nsd package updates.
