At the risk of putting words in his mouth, I'm sure 452 will be quite happy at the return of plain-text emails. =) I'm excited to get an aggregate diff link back again, too; while I hope it isn't coming at the expense of either the single-diff or history link, strictly speaking all three aren't necessary, so having them all would only be a matter of convenience.

Can you say whether the button will be changed to a styled link, as is used in new blog enotifs, or will I have to wait for the tech update/the new enotifs to start rolling out to find out? =)
