Subject Re: [DISCUSS] Migration to SCR
Date Mon, 03 Feb 2014 15:00:24 GMT

I would plan this for Karaf 4.0.0, even if it's internal.

It's an important jump internally in Karaf, and should be addressed in a 
major release.

We just release Karaf 3.0.0, and we have to let people and other 
projects to move smoothly (even if as you said, you should not have impact).
