Tomorrow night at 2359 UTC the wiki beats, where we collect the release notes for F8, will be “frozen” for the final release. From there, we produce DocBook XML sources which go to the L10N folks for translation for the F8 general release. I am hoping there is not too much more to change on the wiki, since each change we make means extra work for the L10N project contributors, but if you have something that needs to make the final release notes, now’s the time to get it in if you haven’t already.
If you miss the deadline, no worries — we will produce a later zero-day update for the release notes that will live on the web until we produce a fedora-release-notes package update.
