On the topic of supported OpenSSL versions.

REL_14-REL_16 supports 1.0.1 (eol 9 years ago), REL_17 bumps that to 1.0.2 (eol
6 years ago) and starting with REL_18 we require 1.1.1 (eol ~2.5 years ago).
By the time we ship REL_19, 3.4 has a few weeks left in support and before 19.1
ships, 3.5 will be the oldest non-EOL version of OpenSSL.
