The Russian Callsign system underwent a major revision in 2010. The changes were effective from 2010-01-21.

Here is the announcement letter from the Russian licensing authority (note  the date), kindly provided by UA1AKE:





The new system is documented in several places. Here are two useful sites:

New Russian Callsign Prefix System  
Russian call sign system 2010


Club Log Prefix Mapping from 2010-01-21


The following table lists all the Russian prefix mappings from 2010-01-10. 

Longer prefixes take precedence over shorter prefixes. Thus, although the R prefix definition is specified as mapping to European Russia, R8 calls, having a longer prefix definition, map to Asiatic Russia, etc. Note that many of these mappings also apply prior to 2010-01-21.

Ukraine Legacy callsigns

Although Ukraine callsigns are not covered by the new system,
some legacy Ukraine calls still exist with the U5 prefix, which is now used for European Russia.
However, as of late January, 2012, RA3AUU advises that no U5 callsigns had yet been issued for Russian stations.
Known Ukrainian U5 legacy callsigns are listed below. This may not be a complete list. Until the first Russian U5 callsign is issued, Club Log maps these calls to Ukraine by the U5 prefix, although, strictly speaking, that has been a Russian prefix since 2010-01-21.
