Got the update last night. This morning my charge port cover didn't auto close. I didn't notice until I got to work. I then pressed the close button and it still didn't close. I pressed it again and it did work. I've never experienced this before, so hopefully it's not a new hardware issue.
edit: now that I think of it, it might have been user error.
I did swipe one of the cards to turn off the energy usage card and I wanted to check something in my rear view camera (check within parking lines)! I must have clicked the port!
I installed 32.6 yesterday morning from 32.2. Regen feels the same to me. It seemed weaker when I was in the week 28 series, but I thought it felt back to normal in week 32. It's probably been the same the whole time, and I'm just susceptible to inception.
My observation so far has been that regen has been very consistent for the same slope, but there is a huge difference between regen on a downslope and regen on the flat: on the flat, you can break pretty hard with regen (uphill, you can throw yourself at the windshield...), but on a reasonable downwards grade, lifting your foot off completely initiates a very gradual deceleration, not something I would call braking -- you need the brake pedal unless you are planning well in advance or were already at very low speeds.
That's on 21.9 and 32.2, with limited experience in-between on 28.3 -- I have not found any difference between the three in terms of regen strength and certainly hope that upcoming releases will not weaken it!
