I haven't found a good answer yet for whether BMW fixed the CCV or if the new one is exactly the same as the old. It seems to be a super common issue so I hope BMW has updated it. But, if it's just one of those things I'm gonna have to replace every 60-100k then so be it.
Also, the cold weather and non cold weather versions are interchangeable, right? That's my understanding at least. I don't know why I have but I will get the cold weather part.

Can't tell what state you're located in, but from studying other posts it looks like anyone living north of I-70 can count on more frequent maintenance requirements on the CCV. It's really important to get your engine oil up to temp for 20-30 minutes at least once a month to help keep your CCV plumbing clear.
Here's a summary of my maintenance history over 311,250 miles:
On a regular basis:
> Rotate tires, inspect pads & Rotors, CV boots, general lookover every 5000 miles
> Oil / Filter change every 8000 miles
> Brake fluid flush every 30,000 miles
> Replace belts and clean CCV every 100,000 miles
> Replace differential and transfer case fluid every 100,000 miles
> Replace sparkplugs every 120,000 miles
> Replace expansion tank, coolant and hoses every 150,000 miles
> Replace bake pads every 163,000 miles (Akebono ceramics)
> Replace rotors??? (243,000 miles on current Brembos)
My unplanned repairs have included:
> Front axles at 60,000 miles (Prior owner didn't maintain CV boots)
> FSR at 78,000 miles
> Two sparkplug coils and accessory belt tensioner at 124,000 miles
> Alternator at 126,000 miles
> Front driveshaft at 136,000 (used a salvage transfer case for cost savings)
> FSR (again) at 159,000 miles
> Thermostat at 176,000 miles
> Rear differential seal at 200,000 miles
> Secondary air pump at 224,000 miles
> Rear suspension bushings and upper control arms at 242,000 miles
> Thermostat (again) at 245,000 miles - at least it was warranty this time
> Steering column double U-Joint shaft at 245,000 miles
> Valve cover gasket at 245,000 miles
> Both fuel tank sending units, fuel pump and canister at 245,000 miles
> Aux fan when the harness got chewed up in the mechanical fan and shorted out at 259,000 miles
> Pre-cat O2 sensors at 260,400 miles
> Water pump at 262,800 miles
> DISA Valve and MAF at 263,800 miles
> Thermostat (again) at 299,00 miles (don’t know what’s going on with these)
> Driver door handle carrier replaced a second time at 310,600 miles (thought they had these fixed finally)
> Intermediate accessory belt pulley at 310,600 miles
The "Expected" replacements have been:
> All four window regulators
> Driver door handle carrier
> Front axle outer CV boots (each side one time)
> Front tension struts
All in all, except for the front driveshaft job that cost $4200, I have really been happy with the vehicle. It doesn't get babied, but I do monitor and maintain it. I think a lot of my good fortune is due to four things: I live in Texas with short winters so I don't have a lot of the CCV condensation problems, my daily commute is 60 miles so the engine oil always reaches full operating temperature, I run the "M" series viscosity engine oil from May through September when I my driving includes 3000 miles of towing a 1400 pound Waverunner and trailer, and I stick with Shell gasoline.
Additionally, I don't change the transmission fluid! I'm a firm believer in leaving it alone and simply installing a full re-manufactured transmission if it ever becomes necessary.
