All of Act 6, with minor edits to cut out redundant walking around and such.
To explain the title, the latest update to the game slightly adjusted the Two Hats secret scene at 0:53:26 for clarity. Also, while the dagger is no longer usable in Act 6, it does add an extra line at 0:57:18.
I tried to be thorough in looking at everything, but let me know if there's anything I missed. On that note, I'll add anything notable I missed to the pinned comment, so be sure to check that too!
