I'll leave a few additional smaller ones here because I haven't gotten around to file bug reports:
- The audio for Jaheira's greeting doesn't play anymore after saving Minsc. I haven't yet checked if this is related to freeing him or hinges on approval.
- The bust that controls the trap door to Helsik's secret basement has become doubled. There now is a free to use and a prohibited one. If you enter the shop via the trap door, the free-to-use one gets turned. (I noticed this in a save in which we had already entered the Lower City map before patch 8)
- If you skill out of Bard and had previously learned "Improved Bardic Inspiration" you get to keep and use it after switching classes.
- Tara does not sell the "Hat of the Sharp Caster" any longer, so she doesn't change places. The only way I found to make her switch to Cora's house was to grab the hat from the roof of Sorcerous Sundries, donate it to Tara and then buy it back. This might not sound like a big deal, but in order for Tara to show up in your story finale for Avatar-Gale you have to have met her twice in the Lower City, so this is a tad annoying when playing the origin.
