The packaged release notes still refer to KDE 3.5.7 and even to KDE 3.5.6 in some translations just a week before release. fedora-release-notes-8.0.0-2 grep -r '3\.5\.7' /usr/share/doc/HTML/release-notes/*
Fixed in our source XML. There will be a zero-day update of the release notes that will include this fix, at least in the en_US version, and probably in many other locales as well. However, it is up to the translation teams to fix this in each language, so there may be some lag.
