The changelog pages back three days at a time
Scroll to the end of the changelog and a button hands you the three days before the ones you're reading. Authors who picked a lane on /dev/null now merge in that color, not one hashed from their login.
You open the changelog from the sidebar and it no longer stops after a couple of days. The three latest days with merges are all there, a 300-merge Tuesday included. Scroll to the bottom and Show older days adds the three days before, right where you are, with focus jumping to the first pull request of the new days. Once there's nothing older, the button goes away.
Credit goes to xHeaven, who taught the changelog to page back through GitHub's history. GitHub lists closed pull requests by when they were last touched, not by merge date, so the server reads 100 at a time, up to 10 pages, and stops once it has passed the start of the third day. It counts days in your own time zone, caches each page for 30 minutes, and finds you by GitHub account id, so the lane color you picked on /dev/null follows you through a rename.
One catch. The changelog lives in the sidebar, and the sidebar only appears on wide screens. Open /dev/null on a phone and there is no changelog to scroll at all.
