  • Late support for UTF-8 encoded client/port names.
  • Allow only one single patchbay connection to or from an exclusive socket (mitigating bug #2859119).
  • Automatic crash-dump reports, debugger stack-traces (gdb), back-traces, whatever, are being introduced as a brand new configure option (--enable-stacktrace) and default enabled on debug build targets (--enable-debug).
  • Probable fix on the audio connections with regard to client/port (re)name changes (an ancient bug reported by Fons Adriaensen).
  • Portaudio device selector is now available (after a patch handed by Torben Hohn and Stephane Letz).
  • A couple of primitive D-Bus interface slots have been introduced, giving the option to start/stop the jackd server from the system bus eg. via dbus-send --system / org.rncbc.qjackctl.start (.stop), (a nice addition supplied by Robin Gareus, thanks).
  • New command line option (-a, --active-patchbay=path) to specify and activate a given patchbay definition file (a simple patch sent by John Schneiderman, thanks).
  • Added one significant digit to DSP Load percentage status display.
  • Tentative support for netjack (slave) by adding the "net" driver to the existing backend driver options on the Setup/Settings section.
  • Converted obsolete QMessageBox forms to standard buttons.
  • New patchbay snapshot now raises the dirty flag and allows for the immediate salvage of patchbay definition profile.
  • Conditional build for JACK port aliases support (JACK >= 0.109.2).
  • Alternate icon sizes other than default 16x16, are now effective to the Connections widget (Setup/Dislay/Connections Window/Icon size).
