Does anyone know when openssl 1.1.1 with tls 1.3 support will be available for SUSE 12 SP3 or later?

We want to get our NGINX web servers and Load balancers using TLS 1.3 as soon as possible. We know the browsers are still playing catch up but we want to be ready when they do.

NGINX TLS1.3 requirements: The TLSv1.3 parameter (1.13.0) works only when OpenSSL 1.1.1 built with TLSv1.3 support is used.

Current openssl version available on SP3 is 1.0.2j-60.24.1
