Backport: Ruby 2.5.X to support OpenSSL 1.1.1 and TLS 1.3
I would be happy that the coming Ruby 2.5.2 would support OpenSSL 1.1.1 and TLS 1.3 .
To do that, it seems at least below patch has to be backported to Ruby 2.5.
net/http, net/ftp: fix session resumption with TLS 1.3
And new ruby/openssl 2.2.2 has to be bundled in the Ruby 2.5.2.
 OpenSSL 1.1.1 release note: https://www.openssl.org/blog/blog/2018/09/11/release111/
