- Thursday, 2025-08-07: release

Developers, please:

   - Book time for automated and manual QA during office hours,
     from Wednesday 13:00 to Thursday 11:00 (Europe/Berlin).
     If you can't, please let the RM know.

   - During these 2 days, don't push any change to the branch
     used for the release.

For people that would like to test this, thanks in advance! more details
as to what to expect will come later.

bye,
