Hello Zodiak, those are great news, thank you very much!

Russian is the second most-spoken language among Steam users so I am sure your addition will please a lot of people.
Regarding v30, so far I didn't add or modify any text key. By the way, you probably noticed a "changes.txt" file in the Localization folder. I use it to keep track of the new features and bugfixes, and also of the text keys added or modified that have not been translated in every language yet. Or you can use a program such as WinDiff instead: keep a copy of the old en_us.xml, then compare it with the new version, WinDiff will emphasize the differences.
PS: Kisses and viruses, you know how to make a splendid entry on CivFanatics.
