Note! The erts-10.2.1 application can *not* be applied independently of other applications on an arbitrary OTP 21 installation. On a full OTP 21 installation, also the following runtime dependencies have to be satisfied: -- kernel-6.1 (first satisfied in OTP 21.1) -- sasl-3.3 (first satisfied in OTP 21.2)

Fixed renegotiation bug. Client did not handle server initiated renegotiation correctly after rewrite to two connection processes, due to ERL-622 commit d87ac1c55188f5ba5cdf72384125d94d42118c18. This could manifest it self as a " bad_record_mac" alert.

Also included are some optimizations

Full runtime dependencies of ssl-9.1.1: crypto-4.2, erts-10.0, inets-5.10.7, kernel-6.0, public_key-1.5, stdlib-3.5
