I have suffered unrecoverable filesystem failure in the server that is managing multitude tasks for U++. I am now reinstalling and recovering things from backups, which might take some time. Meanwhile, some automated tasks might be broken - e.g. nightbuilds and git mirror might not work for a while (while == days).
As of now, I believe everything is restored. Unfortunately, I had arcane problems restoring git mirror operations correctly, after a week of trying, I have just used forced push and rewrote the history; I apologize for any problems this might cause.... (I have learned from the mistake and added those critical parts to backup).
