2.2.0
-----

- fix issue265 and add LD_LIBRARY_PATH to passenv on linux by default
  because otherwise the python interpreter might not start up in
  certain configurations (redhat software collections).  Thanks David Riddle.

- fix issue246: fix regression in config parsing by reordering 
  such that {envbindir} can be used again in tox.ini. Thanks Olli Walsh.

- fix issue99: the {env:...} substitution now properly uses environment
  settings from the ``setenv`` section. Thanks Itxaka Serrano.

- fix issue281: make --force-deps work when urls are present in
  dependency configs.  Thanks Glyph Lefkowitz for reporting.

- fix issue174: add new ``ignore_outcome`` testenv attribute which
  can be set to True in which case it will produce a warning instead
  of an error on a failed testenv command outcome.  
  Thanks Rebecka Gulliksson for the PR.

- fix issue280: properly skip missing interpreter if
  {envsitepackagesdir} is present in commands. Thanks BB:ceridwenv
