Change of Y-DNA haplogroup names by FTDNA

Last year Family Tree DNA (FTDNA) changed their naming system for the Y-DNA haplogroups.  This has been a work in progress over the past year and there is still more work to be done by FTDNA.  The new naming convention replaces the well-known group names like R1b1a2 with the SNP shorthand version of the same haplogroup name, R-M269.  From this time forward, the haplogroups will be known by their SNP names and the longhand version is obsolete, although you will always see it in older documents, articles and papers.

A good explanation of the change can be found in this article:
