Hello operatives!
There is a small patch coming this thursday (v1.091) and since it won't be retrocompatible with the current client the server will be briefly unavailable from 17UTC for at most 2 hours.
There will be some minor balance changes, client/server improvements (hopefully removing forever the 'please wait' issue some of you have been experiencing) and maybe some little new content (badges and/or avatars) depending on various factors.
The deployment and maintenance should take 1h or less but possibly extending to 2h.
