Updated to 17.26.76 and it took about 45 minutes. Nothing different on highways or local streets from what I could tell.
Ok. Will stay and not update.
To be honest, after using autopilot for 1500km road trip, it seems self driving is SO far from being a reality. All it really is fancy cruise control. Self driving implies much more intelligence. There are so many situations where I needed to take over. And when I show it off to people, I always need to answer their questions by admitting that the system cannot read traffic lights, stop signs, avoid pedestrians or cyclists etc. All it does is stay within the lines.
It totally depends on whether or not your driving is predominantly open highway or stop and go / city.
If you do mostly highway driving at highway-ish speeds (e.g. 50 to 90mph), the 17.26 update is TONS better than 17.17, particularly after 100 training miles or so. It's much more capable of following curves and making smooth adjustments.
If you do mostly local driving or dense urban freeway crawling (e.g. 0 to 20mph), and 17.17 works for you under such situations, you might want to hold off, because 17.26's aggressiveness tends to exacerbate bad decisions at low speeds.
For me, it's a bit of a toss up. For my road trips, 17.26 was a net win. A big win. Easiest Tahoe trip ever, including AP1 experiences. But now that I'm back home and driving 7 freeway miles in 45 minutes (glorious silicon valley commutes), I'm less happy with 17.26 compared to 17.17, as previously when the car was crawling at a few mph you can basically leave it unsupervised. Now, it makes all sorts of erratic mistakes at slow speeds.

It's true, and that's why in this case terminology is significant. Autopilot behaves very much like real autopilot on an airplane. The pilot is always responsible to fly the airplane and execute changes.
When I show people AP but they were expecting a robot chauffeur, I like to point out that ATC can't tell any airplane to make a turn, it tells the pilot. The same goes for Tesla AP and stops--for now!
Full autonomy will come, but we need to remind ourselves it isn't here yet. Over hyping AP is bad for PR and for safety.
The lane changing on AP2 definitely got worse for me, it's now a more abrupt neck-snapping turn. My passenger asked me to do future lane changes manually and I was had argument. 17.17.17 took forever to change lanes (6-7 ticks of the turn indicator - and don't even think about letting up after 3 or you're returning to the original lane!); .76 takes about the same total time but with a longer initial lag.
All in all a worse experience. Shame as the routine stay-in-lane driving is excellent.

The following is based on an 18 mile round trip from rural farm into small town 9 miles away. There was virtually no traffic. The roads were relatively flat, no large hills, overcast, early evening.
The update was done with the car's cell connection, 1 pip on the cell connection indication. It went quickly, much quicker than the initial update screen indicated.
A change (from 17.18.50) is that on secondary roads the display used to say autosteering was unavailable. Now it tells you it is restricted to 45 mph. This was on a 2 lane road with a 55 mph speed limit.
It is squirrelly at low speed crossing RR tracks at 35 mph in town, abruptly attempted left turn. It was quickly caught.
It makes abrupt inappropriate turns at slow speeds in town.
These are not gentle, they are fairly aggressive. I held the steering wheel and caught things early, I've got no idea what would have happened had I allowed the car to complete the maneuver.
The car seems quicker. This is purely subjective. It might be wishful. It is an S75D, mfg date May 2017. I do not know the motor codes.
Autosteer works well on a non interstate divided highway, ~5 miles each way, 55-65 mph.
Speed limits seem more accurately represented. The speed limit generally seems to change right at the sign, one was slightly after the sign, one was missed. I don't think it is reading signs although it might be. It is much more accurate than previously.
I'd do the update, just be cautious of the low speed sudden moves. I would not use autosteering in town if there is traffic.
I did attempt to use the windshield washer. It turned out the reservoir was bone dry so wasn't filled at delivery. New owners might want to check for washer fluid before needing to use it. The resevoir doesn't take much fluid. It worked once filled.

Clearly, there must be a new database being used. As I noted yesterday, here in Naples, a few local 45mph (divided, 3 lane) roads that previously were 5+mph restricted are now unrestricted.
HW1 X....
It seems quite unable to handle roads with sharp turns. Why would it knowingly cross over the center line on a one lane (each way) road? This is while doing just 8mph ...
My car did this a lot when I took delivery. The service center realigned the steering and the camera, and it's never done it since.
Looks like the car ahead of you did the same thing. But it's not blue, so the Tesla shouldn't have been using it for tracking.It seems quite unable to handle roads with sharp turns. Why would it knowingly cross over the center line on a one lane (each way) road? This is while doing just 8mph ...

Wellllllll, although I generally agree with all your points, I am MUCH MORE comfortable with AP in a plane than on my MX. I can depend on the plane to make various mid-course way-point changes without worrying about running into another plane 3 feet off my wing-tip
I wait for the day when EV AP will be as safe as for planes...... and it eventually will as you say.

Hmmm, I am more curious as to why you would be taking a photo of the dash during this situation?

I have seen a few more people also reporting this, I strongly suggest you document with some photo's video (safely of course) and send to Tesla. There is something not right here.
At 8MPH it is likely tracking the car in front, at least that is what my AP1 would do.
The issue is that it's not highlighting the car in blue.

Ha, figured out what is wrong with the Xmas Easter egg. Between updates, I had disabled autodoors (got tired of the doors popping open when I would walk through the garage with my keys in my pocket). It will works fine when I re-enabled autodoors.
