In this release, mbed TLS has been updated to v3.0.0. In that version, support for TLSv1.0 and TLSv1.1 has been dropped. Because HTTP Public Key Pinning (HPKP) is no longer supported by browsers for quite some time, I dropped support for that as well.
Let's hope mbed TLS v3.0.0 released will clear the road for TLSv1.3 support soon.
