Today at 12:30 server time (13:30 CEST) we will apply version 8.7.4 on Volans.
This version is needed to apply some backend fixes.
The other universes will be updated later, not today, to have the same version. The announcement for the other universes will be done as soon as we know the date.
We apologize for the short notice for Volans.
