We'd like to inform all Maemo developers that with the public release of PR1.2 for Maemo 5, the libqt4-maemo5-* packages have been officially deprecated in the extras-devel repository, and will be completely removed by June 30th at the latest. If you still have packages that depend on these Qt packages, please alter them or resubmit to extras-devel with either libqt4-* dependencies (for Qt4.6), or libqt4-experimental-* dependencies (for Qt4.7).
