So, a bit of bad news on this update.

I have a V3 battery. It has been rock solid since I got the car. Very small deviations from 265 miles of range at 100% SOC. I just charged to 100% after I got home and I've lost almost 5 miles of range.

Unlikely that your battery has changed. More likely that the battery capacity algorithm or some other variable (there are hundreds) changed.

Have you figured out that there are hundreds of variables that can affect your displayed range on a single charge?
Well aware of that. Definitely going to continue to log. I'm also going to hook up my data logging cable and compare the battery cell values I captured before the update to afterwards. All I'm doing here is providing feedback so people with older vehicles can make educated decisions when applying new firmware. As time goes on, support and care for our vehicles is going to deteriorate. We need to know when it's time to cut the cord.

On the one hand you complain that support will be deteriorating over time but then you complain that you don't want to apply updates. You seem to assume that updates will damage the car.
I appreciate the updates even when they change a beloved "feature". Some people were upset that the Supercharge rate became more conservative. To me, this is Tesla looking out for out batteries. If a slower Supercharge rate will make the battery last longer, that's a good thing. I'll never stop accepting updates.

Updates have most certainly caused significant issues with my car as well as many other P90DL and P85DL owners. I will stop accepting updates at some point.

Browser is still borked but I think that's an emmc issue and not firmware related.

Fresh new 32 gig Swissbit in mine and browser still doesn't work, so without being an expert I would surmise it is a hardware issue. Don't care anyway, never used it really before but thought I would test it with the new eMMC.

Is this the first time you've charged over 90% for a while? There was that update after the mysterious fire in China where people saw their range drop. Mine didn't, but the first time I charged to 95% it dropped about 8 miles of range (last October). It's stayed there ever since. I had zero degradation before that.

On the same trip after the drop I had a 180 mile leg that was mostly flat, almost no wind, steady speed for most of it, and at the end of it the miles used plus estimated miles remaining was my old 90%. The Wh/Mi was right at 285 for that leg. I'd have to run the battery down to essentially zero in good driving conditions to know for sure.

I haven't been offered the new upgrade yet, but my concern is that perhaps Tesla will set aside more of the battery as a reserve. Thus making the battery last longer. I've got a couple years left on the warranty, and 200k miles on the battery. I'd kind of like it to fail before the end of the warranty! That might be a reason to not upgrade. But, I've taken every upgrade they've offered me. Probably do it again.
