I don't think this is actually a significant difference between GPLv2 and v3. At the bottom of the quoted list of requirements, v2 says: > These requirements apply to the modified work as a whole. It is possible that v3's wording was cleaned up to make it clearer that individual file-level changes were not required. I have no doubt that git history would be considered sufficient metadata provided it was included in a release. We probably will never see a court test the attribution requirement in enough detail to settle this (in other words, it probably doesn't matter)
