This bug accidentally eluded the release notes because it was in the wrong state for quite a long time.
Manually edited the 6.3 release notes to include the release note I added in BZ#1069591.
Topic updated: Changes in this release [30483, revision 690511]
Release notes including BZ#1069591 are now ready for review (Revision 6.3.0-21):
Looks good, thanks.
