v1.12.0 (27th Sep 2013)
-----------------------

* #152: Add tentative support for ECDSA keys. *This adds the ecdsa
  module as a new dependency of Paramiko.* The module is available at
  [warner/python-ecdsa on Github](https://github.com/warner/python-ecdsa) and
  [ecdsa on PyPI](https://pypi.python.org/pypi/ecdsa).
    * Note that you might still run into problems with key negotiation --
      Paramiko picks the first key that the server offers, which might not be
      what you have in your known_hosts file.
    * Mega thanks to Ethan Glasser-Camp for the patch.
* #136: Add server-side support for the SSH protocol's 'env' command. Thanks to
  Benjamin Pollack for the patch.

v1.11.2 (27th Sep 2013)
-----------------------

* #156: Fix potential deadlock condition when using Channel objects as sockets
  (e.g. when using SSH gatewaying). Thanks to Steven Noonan and Frank Arnold
  for catch & patch.
* #179: Fix a missing variable causing errors when an ssh_config file has a
  non-default AddressFamily set. Thanks to Ed Marshall & Tomaz Muraus for catch
  & patch.
* #200: Fix an exception-causing typo in `demo_simple.py`. Thanks to Alex
  Buchanan for catch & Dave Foster for patch.
* #199: Typo fix in the license header cross-project. Thanks to Armin Ronacher
  for catch & patch.
