No, let's not forget about the other awful one.
Yeah, I skimmed the notes. I was pretty much bedridden all of yesterday so I didn't have much time to sit at my desk and read patch notes, and subject death spirals didn't cross my mind as something to check for, even though it's incredibly important it gets fixed.
Show me that subject nations finally work (IE they core and convert religion consistently, rather than doing nothing for 30 years or more) alongside rebels being less derpy and I'll still peg this as arguably the best patch to date in spite of the annoyances, unless they're dumping hidden changes on us again. Serious messing with subject nations and liberty desire absent a fix to a longstanding, frustrating, and game-altering bug would come off as pretty sour. All in all most of the changes look good otherwise.
This I agree with. Aside from the obvious ones, I can't really see any major repercussions that pop out as a result of these changes, so this patch does look pretty good aside from the obvious omissions.
