+Incompatibility with snapshot 20080629
+======================================
+
+When TLS support is not compiled in, the Postfix SMTP server no
+longer ignores the "smtpd_tls_auth_only = yes" parameter setting.
+Earlier Postfix SMTP server versions would announce SASL support,
+and would accept SASL login or sender information.
+
+Major changes with snapshot 20080629
+====================================
+
+The Postfix SMTP server's SASL authentication was re-structured.
+With "smtpd_tls_auth_only = yes", SASL support is now activated
+only after a successful TLS handshake. Earlier Postfix SMTP server
+versions could complain about unavailable SASL mechanisms during
+the plaintext phase of the SMTP protocol.
