... and so on. Until further notice: tagging happens the first saturday of every month, and the public release is one week later.

The last 2 weeks before every tagging day are the string freeze, so translators can avoid working with a moving target.
There is no feature freeze, as long as the features are unittested and reviewed, and don't collide with the string freeze.
