The fedora-release-notes package in F23 is still for F22:
"This document provides the release notes for Fedora 22..."
it is included in all live images except, I think, Workstation (because it's part of the @standard group, which is in fedora-live-base.ks). So the KDE, Xfce etc etc lives have a menu entry which shows you the Fedora 22 release notes.
This is a clear violation of "The final branded release notes must be present on release-blocking images and the appropriately versioned generic release notes must be available in the release repository.", which somehow no-one thought to check until now. Le sigh.
We have an update:
it just never got pulled into any composes.
That's +3, accepted for now. Will be considered further at Go/No-Go tomorrow; we will have RC7 with this change, and RC6 without, so we have choices.
Folks have said this looks good in RC9.
For the record, this was discussed at 2015-10-29 Go/No-Go meeting, acting as a blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-meeting-2/2015-10-29/f23-final-go_no_go-meeting_2.2015-10-29-16.00.html . The decision to accept it as a blocker was generally affirmed.
Looks good in RC10.
Update was included in RC10 and pushed stable.
