• JACK MIDI support is now being introduced. Connections window now has a brand new MIDI tab, the older being renamed to ALSA, as for the ALSA/MIDI sequencer conveniency. The server settings now include the MIDI driver setup option (ALSA backend only).
  • Application icon is now installed to ${prefix}/share/pixmaps; application desktop entry file is now included in installation; spec file (RPM) is now a bit more openSUSE compliant; initial debianization.
  • Invalidation of the JACK client handle is now forced right on jack_shutdown notification, preventing a most probable fatal crash due to jack_deactivate and/or jack_client_close being called after the jack_watchdog kicks in.
  • Default font option names were adjusted to "Sans Serif" and "Monospace", wherever available.
  • The "keep child windows always on top" option is not set as default anymore, because window focus behavior gets tricky on some desktop environments (eg. Mac OS X, Gnome).
  • Autoconf (configure) scripting gets an update.
