Although one can disable TLS 1.0 and 1.1 locally today, it’s unlikely people will do that. It is no longer a sensible default to keep TLS 1.0 and 1.1 enabled by default.
Other vendor announced that they will be disabling client support for TLS 1.0 and 1.1 in spring 2020. I would like to align with them, and set compiled in default to TLS v1.2 in all the libraries. The API/ABI will be preserved and one would be able to turn TLS 1.0/1.1 back on, using config files or API calls as needed.
Are you ready for TLS v1.2?
