ChangeLog.d/tls13-server-version-negotiation.txt

Features
   * Add support for server-side TLS version negotiation. If both TLS 1.2 and
     TLS 1.3 protocols are enabled, the TLS server now selects TLS 1.2 or
     TLS 1.3 depending on the capabilities and preferences of TLS clients.
     Fixes #6867.
