Which version of Karaf should we choose
Hello,
My question is in the title : for a new project, which version of karaf
should we choose ?
When I read the blog post from Christian (
http://www.liquid-reality.de/display/liquid/2013/12/28/10+reasons+to+switch+to+Apache+Karaf+3).
I should use the version 3.
But on the official web site, in the release schedule section :
http://karaf.apache.org/index/community/releases-schedule.html
I see that karaf 3 has only a partial support for OSGi 5 and karaf 2.4.x
has full support.
I don't get why previous version of karaf have a better support of latest
OSGi version.
Could someone enlighten me on ?
Thanks,
Arnaud Deprez

Hi,
I second Achim there.
Again, the Karaf 2.4.x purpose is for migration: it's for the user that
wants to easily move from 2.3 to 3.0.
For a new project, from scratch, I would advice 3.x for GA.
Regards
JB

Hi,
actually version 3 is "older" compared to version 2.4.
2.4 is there to have an easier transition phase between 2.3. and 3.0 since
we changed APIs in those versions.
So right now I'd go for 3.0.3 which has a good support.
OSGi 5 is only because the 3.0.3 line uses Felix 4.2.1, cause at that time
4.4. hasn't been released. [1]
While 2.4. (which has been released later) uses Felix 4.4.1. An upgrade to
it would be a major change and therefore requires a major version bump.
The next version to come is 4.0 which also has Felix 4.4.1 as dependency,
so if you're are starting with a new Project you
might want to work with the soon to come 4.0.0.M2 as 4.0.0 will be our next
focused version.
Regards, Achim
