Apache Karaf 2.3.x branch will be soon entering the planning phase, as such I'm preparing for the release management role.
To prepare I've selected a bottle of La Cour Pavillon Bordeaux Merlot - Cabernet Sauvignon 2009 to decant while listening to some Esthero albums.
Current high lights of this new branch include an upgrade to Felix Framework 4.0.1, Eclipse Equinox 3.7.1, OSGi Compendium 4.3.0, and a multitude of other supporting libraries. All of the updates seen in this kit would have broke compatibility if applied to the Karaf 2.2.x line, hence this new branch (command syntax remains the same however, so its part of the 2.x family - see Karaf 3.x for major changes). The release notes for 2.3.0 have not been drafted at this time, so many more new features, bug fixes, and innovations will make appearances in this RC.
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 Esthero videos. I'm looking forward to starting the 2.3.0 release process soon.
I'll be posting updates to our Twitter stream (#karaf) and on our IRC channel (irc.codehaus.org #karaf).
