Tested on Version 5.0.0-rc3 (Build 2010051201) .
1. Yep, it works. (Now I see following: Thu, 13 May 2010,

2. But it would be nice if there is a way weekday and month name translated to russian as well (according to language tag or php timezone).
3. Much of other text that shows nice in 4.3.1 is crumbled in the same way in this version. Screenshot attached.
