Chargers on I-10 updated.
Saw 145 kW at Junction, 136 at Ozona, 137 at Fort Stockton.
Previous best was 118 kW at any of these three.
So: why is the Fort Stockton display different than the other two?
Does the newly installed 2019.20.4.1 have anything to do with this?

I'm surprised to see 145kW at all, but (and maybe this all goes without saying) there are a number of factors that go into charging power, including battery temperature, state of charge and losses in the cables, and obviously the power the charging station is capable of delivering. Longer or narrower (lower gauge) cables are going to create more resistance and thus more power loss to heat.
Assuming everything else being equal which is pretty unlikely, a 480V, 300A supercharger will deliver 144kW without any heat loss. Assuming 2/0 gauge copper cable probably in use has 0.0980 ohms of resistance per 1000 ft, which doesn't sound like a lot, but at 300A that's around 1 Watt heat loss per foot of cable.
Now the firmware change absolutely could have a significant effect on the charging curve, since the car and not the charger (I believe) determines the charging curve. That said, I'd expect that with all else being equal the charge curve would be the same and there wouldn't be any reason for one supercharger location to be handled differently in software than another.

Isn't this just the difference in having the display set to Energy rather than Distance? Or did I entirely miss the point?

Dr J: yep, don't know how I missed that.
Wouldn't it be nice if both the % and the distance were displayed?
Tesla Remote app shows both - why not show both on the dash display?

Because it is Tesla. They used to show volts and amps if energy were selected. Now just kW if dialed into energy instead of distance.
No one, repeat, no one has ever been able to figure out Tesla logic. Best we just accept what we get and be happy driving our cars!
I'm wondering this too since I'm driving right now. If not, then I'll really have to conserve as much energy in order to make it from Van Horn to Ozona.

I was there last night around 9pm. 3A and 3B are dead, but the other six chargers work, including 2A. The latter has not lit up at night since (at least) Feb. 2019, but otherwise has always worked fine.

On-board nav shows "Temporarily Closed" due to a pedestal damaged back on 01/08.
Despite what the nav shows, at least four pedestals were working yesterday afternoon.
Alternative is the VW penance station at Walmart, but you'll need an adapter.
I notified Tesla, told them it made us look bad. We'll see if they respond as quickly as they did at VanHorn.

Did Van Horn actually get fixed?
Also, it's annoying how the Nav often says "Temporary Closure" when many pedestals are still working. I've seen this happen at many other superchargers as well. In this case, it should say "Reduced Service," preferably with some type of description. I.e. "all pedestals working at reduced rate" or "only 4 pedestals working, but at full power," etc.

Um, guess my sarcasm re Van Horn wasn't communicated very well. Sorry

Y’all please keep checking-in to PlugShare. It is a useful resource if updated.
(I didn’t “get” the Van Horn reference either, but whatever)

The reference to Van Horn pertains to 4A and 4B that have been dead since, at least, June 2018. That's 20 (or more) months out of the 35 months that this Supercharger has been opened.
