I'm talking about the change on the 17th of October, only a couple of days ago, not the one from a month ago which I know (and mentioned) is the new pass manager. The change doesn't show up in all of the graphs, but for the cases where it does show, it's a similar size improvement to the new pass manager. Maybe it was enabling PGO rather than any code change, I've heard it mentioned that happened recently.
