According to TeslaFi, firmware 2019.20.2.1 5659e07 just starting rolling out 15 minutes ago...in a big way. It's currently showing Model 3's updating at 3-5 cars per minute. That works out to about 6-10% of the fleet per hour, which is fast. This is a lower revision than 2019.20.2.5 which is a limited release, EAP-only rev first sent out on Saturday. It looks like 18.104.22.168 is only going to Model 3's in North America and appears to be updating from all previous revs. Who's going to be the first to post the release notes??
