Version 0.7.0:
- Support for DSN (Delivery Status Notifications) was added via
  the new commands 'dsn_notify' and 'dsn_return'.
- The 'tls_nocertcheck' command was added. It disables all server 
  certificate checks. Use it if you get certificate check errors but
  still want to use the SMTP server with TLS/SSL.
- The 'nostarttls' command is now called 'tls_nostarttls'. 
  Please update your configuration file.

Version 0.6.5:
- License clarification:
  msmtp is released under the GPL with the additional exemption that
  compiling, linking, and/or using OpenSSL is allowed.
