Description Conrad Kostecki gentoo-dev 2021-02-17 20:20:00 UTC
This release also fixes a security issue, where channel binding, which connects the authentication layer (i.e. SASL) with the security layer (i.e. TLS) to detect man-in-the-middle attacks, could be used on connections encrypted with TLS 1.3, despite the holy texts declaring this undefined.
