Hi, We've been supporting jack sound server [1] for a long time. Currently, we're supporting jack1 as media-sound/jack-audio-connection-kit. However, jack2 has been out for quite some time.
As its name does not imply, jack2 is not really the successor of jack1 but rather another implementation of the same protocol [2]. As such, I don't think it is wise to add jack2 as an update to jack1 in media-sound/jack-audio-connection-kit but rather to add a new package (media-sound/jack2) along with a virtual that packages can depend onto. Proposed ebuild for the virtual is here: https://github.com/suhr/gentoo/commit/1aebd8e72ff4ff2665761fc3b07f796945aa0943 Best regards, Alexis.
