cp2k release goals

[Axel]

happy new year everybody!

since the beginning of a new year is also a time for
making plans and resolutions, i'd like to revive a subject
that has been discussed quite a bit, but is important to
many cp2k _users_: a cp2k release.

IMO cp2k has gained significant maturity over the last
year(s) and despite plenty of new and exciting developments,
many cp2k users simply need a point of reference version that
(super)computing center staff can support for them and where
one can write pre-and post-processing tools for without having
to change the code every other day or so.

in order set the bar not too high, i'd like to simply start
a discussion on what features are ready to be used for
production or which features people would (realistically!!)
like to see in a release and which needs most urgent fixing.

once this is settled, the next step would be to gang up and
collect and run proper release tests on as many different
platforms as possible and finally find people that are willing
to maintain a release branch (i.e. carry over bugfixes from
the development, maintain backward compatibility).

what do you all think?

cheers,
    axel.
