Fractal string freeze and next release

[Alexandre Franke <afranke gnome org>]

Hi,

We’re gonna release 4.2.1 on September 21st to get all the newly
committed translations out to our users. No string change should
happen until then, so it would be awesome if you could take this
opportunity to increase coverage.

Thank you all for your work, it is very much appreciated.
