This release adds support for the authentication mechanism SCRAM-SHA-1 via GNU SASL. The new command tls_fingerprint allows one to trust one particular TLS certificate, in case tls_trust_file cannot be used for some reason. The new script msmtp-gnome-tool.py manages Gnome Keyring passwords for msmtp.
This release contains a security fix: When using OpenSSL, NUL characters in the Common Name or Subject Alternative Name fields of certificates are now handled properly.
