You may want to hold off upgrading your esc's with this latest official release, it's giving me a bunch of trouble with certain esc's. Once the new rev is loaded they can no longer be seen with BLH configurator and cannot be reflashed with BLH Suite either. What is worse is that if you try to reflash with the BLH Suite they may erase but not program (write failure) which leaves you with a dead esc. My E-Max Bullets work fine with 16.7 but the Eachine 20A esc's are pretty much toast now. There are a number of people reporting the same thing on the Github pages about other esc brands too.
