I am happy that you opened this topic, though the title already says everything: There is a new release candidate and a changelog in the usual place.
Well, as you showed the courtesy to open the topic and to read what someone writes about stuff, about which everything has been written, I might tell some more.

So, what happened since RC1? Some guys did marvelous testing, and created some nice and good bug reports. (Sometimes I think the latter part is more difficult)
That way some well hidden desyncs could be fixed. Even more impressive: Most of them have been present since 0.5.0. The devs had also some fun, as one of those desyncs kept at least two of them busy for a whole day (8 am to 7 pm). Especially as two independent bugs coincidented [1]

Finally I would like to remind you, that there is still some tedious "RC" in the version of the new release. I hope you know what to do
