Our previous trees showed a branch called I-V2860, it contained two men with the same surname, they have ancestry from Poland. Our previous trees showed 17 SNPs as equivalent to V2860, one of these SNPs is named Y100616.
But this update shows a new Big Y result for another man with Polish ancestry. This result split the I-V2860 haplogroup. Now there is an upstream branch called I-Y100616 which contains all three men, and a redefined I-V2860 branch which contains only the two men with the same surname.
This update shows another branch called I-A21222 (also known as I-BY42258), it contains three men with the same German surname (one of these men is not a member of the I-P37 project). It's part of the upstream branch called I-BY42257. Previously BY42257, A21222, BY42258 and many other SNPs were considered to be equivalent. Thanks to a recent Big Y for a Russian man, we know that BY42257 is the oldest and most widespread of these SNPs. (this paragraph was edited on 2019-10-31)
