A proper discussion would be more proper in the documentation rather
in the release notes.
A quick note might say that gnutls implements the TLS safe
renegotiation counter-measures as described in RFC5746, against a
plaintext injection attack that affects TLS as is currently used by
HTTP(S) protocol. More information about the vulnerability at
Unfortunately fully deployment of the solution requires breaking
backwards compatibility with older servers and clients. For that
reason gnutls enables it but does not enforce its security features
unless the peer also supports safe renegotiation, to maintain
compatibility with existing software. This decision will be
reconsidered once the majority of internet servers/clients that use
TLS have adopted safe renegotiation.
