I agree with this and like the change in 5.8. This feels much more natural to me...
All those guys complaining about regen being set differently, can you check before griping? It is an easy thing to do. Drive fast, let up quickly on the accelerator while you look at the power meter - does it go right to 60 kW regen or does it ramp to it? I'd recommend doing this test in an isolated area 
FWIW, I didn't notice regen change, but I haven't done my experiment above either yet.

Yeah, that's a good one!
Obviously there isn't enough experience yet to draw final conclusions, but it appears that it all depends on where you are in the 12V recharge cycle when reaching your destination. At least on my car, the 12V recharge cycle takes anywhere from 2 to 3 hours to complete. It further appears that the 12V battery is not always charged when the car is being driven, so when reaching a destination, 12V charging could be done, or it could take anywhere from 0 to 3 hours before it is done.
Looking at yesterday's and today's data, it appears that sleep mode only engages at least one hour after 12V charging is complete.
So, you will lose range while the 12V is charging. Then, once the car goes to sleep, you will not lose much if any range until it needs to charge the 12V again, which will now be much later / less often than before sleep mode was available.

That sounds like a good theory...
Except that the 5 miles I lost in 22 hours were while the car was plugged in. I use scheduled charging, and the car charged Sat night. On 4.5, and likely in 5.x, top-offs only happen every other night -- so it did not charge Sunday night. So if your theory is correct, why didn't it pull from shore power to run the DC-DC converter and top off the 12V?
Also, the 12V doesn't hold all that much (I don't know the Ah rating offhand...) -- while a trickle charge makes sense, that alone should barely register against the main pack. The rest would be from the car not sleeping -- which was ~7-8 miles of range per day. 0-3 hours would equate to perhaps a loss of 1 mile of range, not 5...
Edit: My car lost 5 miles of range while parked for ~9 hours at work. That's a much faster rate than I've previously seen -- it was usually 3 under 4.5. Screens appeared to wake from sleep. I rebooted both screens and will see if that helps. If not, I'll be calling Service...

Asked the same question over in the 5.6 thread a couple of days ago (before I knew there was a 5.8 thread!). It's clearly less aggressive at first--question is whether it is just a different profile and it eventually makes it up. I'm not sure it does. Personally I like the old way better.

My car is new and came with 5.6. Got the update last night to 5.8. It listed a whole bunch of "new" features that I already had in 5.6. The only thing that looks "new" to me is the TPMS and the Wiper thing. Is there anything else that's different? I was hoping it might solve my GPS issue (my car's position is not reflected correctly when in Nav mode).
Personally I also prefer the "old" regen profile, I found it more useful in city stop & go traffic.
Now, with the gradual onset, I have to use my brakes more, as others have noted.
(Partial cross-post): Another thing I noted today (correct me if this already occurred in 4.5), is that when the car is locked and charging, pressing on the charge handle button interrupts the charge. I seem to remember the button doing nothing on a locked car in 4.5.
In my limited experimentation, if the car is charging but delayed charging is set to on, the charging will not resume when the handle button is released (will defer to the delay programmed hour). This may be a problem if someone plugs in to charge at a public station without turning their usual delayed charging off, and having someone fiddle with their charging cable when they are away.

I had doors opening by themselves. The SC upgraded my early door handles to new ones. But I'm vin 2201. Maybe yours is newer.

But the delayed charging is location sensitive so unless you set delayed charging at a public station it won't matter.
Only initially. After a second or two it gradually kicks into the full regen (unless it's cold outside and it still warming things up).
They don't make money by having us replace brake pads. Besides, nobody says we have to go to them for brake pads anyway. (fyi brake pads are included in service plan anyway so they are free).
Agreed; there's less of a jerk when you drop cruise control. It's not a huge difference, but it is clearly there.
Also I think the regen changes are helping me lower Wh/mile and increase range because it's not so heavy a pull back initially. Lots of times I don't need the full regen and I end up doing more stop and go so these changes seem to increase efficiency (lower wh/mi) effectively extended range and the life of the battery since i am using it less.
OK, I'm noticing a bunch of changes with 5.8. Regen is clearly "softer" at first - it does ramp up to max regen as before but more slowly. I'm having to change my driving style as I'm using a lot more brake now.
I think the same concept has now been applied to acceleration too - the early acceleration is definitely "softer" although max seems the same. It's as though you have to push the pedal further to get the same level of acceleration, just like you have to lift off the accelerator more to get the same level of regen as before. Better modulated for your passengers perhaps but I kinda miss the jerkiness of the pre-5.8 regen/accel combo.
Finally, I think the "Sport" steering mode has been softened up as well, now closer to the standard mode, particularly at slow speeds. Easier to one-finger steer at low speeds, but I miss the "connectedness" of the firmer pre-5.8 sport steering.
Weird how your car can "change" overnight.
Edit: I upgraded from 5.0 -> 5.8
