It seems I had only the master branch in my tree. A git fetch showed all the branches including 8.2.1.

Hi,

In the GHC git repo how do I figure out which commit belongs to release 8.2.1. I cannot find 8.2.1 in "git tag" output. I tried "git log" and searching for 8.2.1 but there seems to be no definitive comment marking 8.2.1.
