Builds of OM 6.10 beta 3 are available at the usual places.
I’m currently having issues with 32bit libjack on newer fedora (fc22, fc23), and suspect bugs in the maintained packages (other 32bit apps show same behavior). Things work as expected in fc21.
All feedback vs. the behavior of OM with jack in newer OS are very wanted. Please send reports of OS, jack version (build info) etc. Thanks!
Thanks: Karim Haddad for testing .debs, Hans Wilmers for double checking 32bit jack clients on 64bit servers.
