What 'active' issues go in the next stable release?

We aim to have at least two stable releases a year with major improvements of the Flickr module. This parent issue holds all of the active issues that we would like to see solved in a next stable release. It gives an idea of when a new stable release can be expected and what will be solved in it. Also take in consideration the date of the current stable release. If it is older than six months it should be time for a new stable version.

New sites (not upgrading) should consider to use the dev version that contains the latest features. It is tested and safe to use.

Nota bene:
Obviously all other commits go in a new stable version as well.
