There's a new release candidate of JACK1 now available. Because of the magnitude of a couple of the changes, some wider testing would be appreciated before 0.125.0 can be released.
(tagged in git as 0.125.0.rc1)
Changes since 0.124.1, in rough order of significance:
* use topological sort when ordering clients. Previous sorting implementation would
generate incorrect ordering of clients in some (unusual, but not uncommon) conditions.
* in the alsa_midi slave driver, fix hotpug device enumeration. JACK1 will now respond
to MIDI devices being connected and disconnected while running.
* increase maximum size of a single JACK MIDI event to 64 bytes
* in the alsa_midi slave driver, fix thread start/stop handling when freewheeling
* add support for jack_port_rename()
* drop support for CPU cycle counting clock, use kernel clocksource instead
* fix a double-fork that left zombie processes around
* improve the validity and usability of the return value of jack_frame_time()
* fix failing metadata look up by clearing UUID parsing buffer before use
* support unescaped double quotes in $HOME/.jackdrc
* fix memory leaks of metata key/value pairs
* fix crash caused by incorrect jack_error() format string
* remove option help from jackd and point user at documentation
* fix problems with garbage keys in metadata
* fix out-of-tree builds
* update
configure.ac to work with current-ish autotools with less errors
* use gcc atomics and CLOCK_REALTIME for generic CPU builds
* a handful of other minor bug fixes
