Currently, 66.2% of Android devices are running version 7.1 or above. The remaining 33.8% of Android devices will eventually start getting certificate errors when users visit sites that have a Let’s Encrypt certificate. In our communications with large integrators, we have found that this represents around 1-5% of traffic to their sites. Hopefully these numbers will be lower by the time DST Root X3 expires next year, but the change may not be very significant.
Can we get another cross-signature? We’ve explored this option and it seems unlikely. It’s a big risk for a CA to cross-sign another CA’s certificate, since they become responsible for everything that CA does.
This release was bumped to 2.0, not because of the magnitude of features (which is actually smaller than past releases), but because of a few changes that are backward incompatible.
