Here are the release notes:
--------------------------------------------------------------------------------
fetchmail-6.6.0 (not yet released):

## FEATURE:
* SMTP TLS and STARTTLS support. By default, this works opportunistically,
  attempting to set up a TLS connection to the smtphost if it understands EHLO
  and offers STARTTLS, but will not enforce peer certificate validity for
  compatibility, esp. because "localhost" (the default SMTP host) usually
  isn't listed in the X.509 certificates.
    Behavior can be tweaked by adding /notls (cleartext connection), /tls
  (TLS-wrapped connection, negotiating TLS before conversing otherwise),
  or /starttls (requiring EHLO to offer STARTTLS, requesting the latter and
  requiring the server certificate to validate) to the SMTP host's name.
    Also, you can add /tlsproto=... where ... accepts the same parameters
  as the --sslproto option, which see.
  Ports, if not specified, default to 25 for opportunistic and /notls modes,
  465 for /tls and 587 for /starttls, but can be overridden either by giving,
  say /25 or /smtp for /starttls.

## TRANSLATIONS:
These will be requested only after fetchmail 6.5.7 will have been released.
