"ISOGG is committed to a tree with the minimum of confusion for users, so naturally, with the publication of the new tree in Karafet (2008), ISOGG will be changing several haplogroup names to conform to the choices made by Karafet ... Meanwhile, new SNPs are being announced or published almost every month. ISOGG’s role will be to maintain a tree that is as up-to-date as possible, allowing us to see where each new SNP fits in."
