10.5.2 Update Fixes Russian-PC, Latvian, and Chinese Keyboards?

According to its release notes, the 10.5.2 update for OS X fixes the problems mentioned in this blog with the Russian PC and Latvian keyboard layouts that came with 10.5.0. But I still don't see any ё in the Russian-PC ANSI layout on my machine. Apparently it is only present on an ISO/European keyboard. On the other hand, although not mentioned, it looks like they may have fixed the bug in HaninYiTian.
