Looking at the diff, I think there are missing changelog entries:

ignition-gazebo4_4.9.1...ign-gazebo4

Also, we should have bumped the dependency requirements in ign-gazebo4-release, see the changes in CMakeLists:

ignition-gazebo4_4.9.1...ign-gazebo4#diff-1e7de1ae2d059d21e1dd75d5812d5a34b0222cef273b7c3a2af62eb747f9d20a
