The Qt5 (meta-)port and all its dependent ports have been updated to Qt 5.5.1 in FreeBSD. Special thanks to Yuri Victorovich, who did an independent Qt 5.5.1 port and whose work has been gratefully incorporated into this update. Thanks also to Ralf Nolden for pushing for better upgrade-paths and co-installability.
Users of Qt5 on FreeBSD are advised to consult the UPDATING file, as some ports have been split. Users of Qt4 are unaffected by this change; Qt4 and Qt5 can be co-installed on FreeBSD.
This update opens the doors to (finally!) getting KDE Frameworks and KDE Plasma Desktop ports into the official ports tree.
There is no Qt5 option in the nethack 3.6 port, nor is there one planned.
