Apache Karaf 2.2.x branch is currently in the works - this patch has been made a priority due to the discovery of a regression that appears in Karaf 2.2.6 (ConfigAdmin update are not flushed into the configuration file).
To prepare I've selected a bottle of Santa Rite Reserva Carmenere 2009 to decant while listening to some Bryan Adams albums.
As this release's purpose to repair a recent regression few other changes are expected to be included. As mentioned in a prior post, the new Apache Karaf 2.3.x branch has been created to collect improvements to the Karaf 2.x line - the 2.2.x should from now on only contain bug fixes.
The wine will of course only be sampled after being gave proper time to breath in its container, after the first release candidate has be up loaded for voting (see our release guide for more details on our process).
Unfortunately I can't share the wine with you, but I can share a few links to some Bryan Adams videos.
I'm looking forward to starting the 2.2.7 release process soon. I'll be posting updates to our Twitter stream (#karaf) and on our IRC channel (irc.codehaus.org #karaf).
