The changes are impressive, many players said it looks like a whole new game :)
This update is the biggest update ever, and very challanging for us, because we made some changes in the player format, so this means that we will have to actually convert all the users from the old format to the new format.
With this occasion, we are also pruning some users (those with low skills that didn't log in 6 months or more).
The update is supposed to take 2 hours, right now we are in the second phase, where we archived the old users and now we are converint them to the new format. Then we will backup up the users in the new format, just in case, then start again.
Hopefully, everything will be OK..
[edit]
Well, there were quite a few problems, not quite unexpected though. Then there are some problems with some map definition files, like exiting from some buildings in the wrong place, etc.
There was a bug in the players convertor, so we had to have a minor rollback and reconvert all the files...
