(I sent this to fedora-devel-announce earlier this morning, but didn't see any copy land in fedora-devel, so here ya go). Now that the KDE 4.0 RC1 is available (and development churn has slowed), the KDE SIG will be working towards incorporating as much of kde-4.0 (rc1) into rawhide the week of Dec 1-7. The gory outline of making all of this work are detailed on http://fedoraproject.org/wiki/Releases/FeatureKDE4 The challenge will be replacing the current kde3-based desktop with a kde4-based one, while at the same time still providing a kde3 development platform (ie, so one can still build/run kde3 applications). This announcement serves two primary purposes: 1. Serve notice to expect kde-related borkage the week of Dec 1-7. 2. Inform kde(3)-based package maintainers that spec-files that currently include constructs like: BuildRequires: kdelibs-devel BuildRequires: kdebase-devel will need to be updated to BuildRequires: kdelibs3-devel BuildRequires: kdebase3-devel instead. These kde*3 virtual Provides are in place now (in all F7+ branches, and without Epoch's too, btw), so there's no need to wait to make this change. Likewise, kde4-based applications can/should include constructs like BuildRequires: kdelibs4-devel (avoiding references to just kdelibs-devel which can be ambiguous). -- Rex
