If more than one annotated tag points at the same commit, use the tag whose tagger field has a more recent date stamp. This resolves non-deterministic cases where the maintainer has done: $ git tag -a -m "2.1-rc1" v2.1-rc1 deadbeef $ git tag -a -m "2.1" v2.1 deadbeef If the tag is an older-style annotated tag with no tagger date, we assume a date stamp at the UNIX epoch. This will cause us to prefer an annotated tag that has a valid date. We could also try to consider the tag object chain, favoring a tag that "includes" another one: $ git tag -a -m "2.1-rc0" v2.1-rc1 deadbeef $ git tag -a -m "2.1" v2.1 v2.1-rc1 However traversing the tag's object chain looking for inclusion is much more complicated. Its already very likely that even in these cases the v2.1 tag will have a more recent tagger date than v2.1-rc1, so with this change describe should still resolve this by selecting the more recent v2.1.
