======
- Fixed a misspelled TLS cipher. ``CDHE-ECDSA-AES128-GCM-SHA256`` should have
been written as ``ECDHE-ECDSA-AES128-GCM-SHA256``. This typo simply meant
that cipher was unavailable for use, the other nine strong ciphers were/are
still fully available.
- :ref:`configuration-options` document compiled.
- In-line comments in configuration files are now supported and the comment is
ignored.
.. code-block:: ini
listen = :25, :::25 IPv4 and IPv6
Will be read as.
.. code-block:: ini
listen = :25, :::25
- Large scale documentation updates. Pretty much everything should be fully
documented now, including all :py:exc:`SystemExit` calls including their
return codes.
- Added an option to disable :py:obj:`ssl.OP_SINGLE_DH_USE` and
:py:obj:`ssl.OP_SINGLE_ECDH_USE`. Reduces CPU overhead at the expense
of security. Disabled by default, warns if used. Slightly better for high
load environments. -- :ref:`command-line-options`
