  Thanks to Jason R. Coombs for the patch.
* :bug:`154` (`Fabric #876 <https://github.com/fabric/fabric/issues/876>`_)
  Forwarded SSH agent connections left stale local pipes lying around, which
  could cause local (and sometimes remote or network) resource starvation when
  running many agent-using remote commands. Thanks to Kevin Tegtmeier for catch
  & patch.
* :release:`1.10.0 <2013-03-01>`
* :feature:`66` Batch SFTP writes to help speed up file transfers. Thanks to
  Olle Lundberg for the patch.
* :bug:`133 major` Fix handling of window-change events to be on-spec and not
  attempt to wait for a response from the remote sshd; this fixes problems with
  less common targets such as some Cisco devices. Thanks to Phillip Heller for
  catch & patch.
* :feature:`93` Overhaul SSH config parsing to be in line with ``man
  ssh_config`` (& the behavior of ``ssh`` itself), including addition of parameter
  expansion within config values. Thanks to Olle Lundberg for the patch.

  local host's FQDN. Thanks to John Hensley for the patch.

  files.  Thanks to Parantapa Bhattacharya for catch & patch.
* :bug:`102 major` Forego random padding for packets when running under
  ``*-ctr`` ciphers.  This corrects some slowdowns on platforms where random
  byte generation is inefficient (e.g. Windows). Thanks to  ``@warthog618`` for
  catch & patch, and Michael van der Kolff for code/technique review.
* :feature:`127` Turn ``SFTPFile`` into a context manager. Thanks to Michael
  Williamson for the patch.
* :feature:`116` Limit ``Message.get_bytes`` to an upper bound of 1MB to protect
  against potential DoS vectors. Thanks to ``@mvschaik`` for catch & patch.
* :feature:`115` Add convenience ``get_pty`` kwarg to ``Client.exec_command`` so
  users not manually controlling a channel object can still toggle PTY
  creation. Thanks to Michael van der Kolff for the patch.
* :feature:`71` Add ``SFTPClient.putfo`` and ``.getfo`` methods to allow direct
  uploading/downloading of file-like objects. Thanks to Eric Buehl for the
  patch.
* :feature:`113` Add ``timeout`` parameter to ``SSHClient.exec_command`` for
  easier setting of the command's internal channel object's timeout. Thanks to
  Cernov Vladimir for the patch.
* :support:`94` Remove duplication of SSH port constant. Thanks to Olle
  Lundberg for the catch.
* :feature:`80` Expose the internal "is closed" property of the file transfer
  class ``BufferedFile`` as ``.closed``, better conforming to Python's file
  interface.  Thanks to ``@smunaut`` and James Hiscock for catch & patch.
