RFC 8996 says: > This document formally deprecates Transport Layer Security (TLS) > versions 1.0 (RFC 2246) and 1.1 (RFC 4346). Accordingly, those > documents have been moved to Historic status. These versions lack > support for current and recommended cryptographic algorithms and > mechanisms, and various government and industry profiles of > applications using TLS now mandate avoiding these old TLS versions. > TLS version 1.2 became the recommended version for IETF protocols in > 2008 (subsequently being obsoleted by TLS version 1.3 in 2018), > providing sufficient time to transition away from older versions. > Removing support for older versions from implementations reduces the > attack surface, reduces opportunity for misconfiguration, and > streamlines library and product maintenance. This code probably only talks to our own receiver which uses libmicrohttpd. That in turn delegates to GnuTLS, which supports 1.2, 1.3, 3.0, etc.
