**************
2.2.6 (unreleased)
==================
Unreleased
==========
- Undo breakage on Windows machines where ``sys.prefix`` can also be a
``site-packages`` directory: don't remove it from ``sys.path``. See
https://github.com/buildout/buildout/issues/217
- Remove assumption that ``pkg_resources`` is a module (untrue since
release of `setuptools 8.3``). See
https://github.com/buildout/buildout/issues/227
- Fix for #212. For certain kinds of conflict errors you'd get an UnpackError
when rendering the error message. Instead of a nicely formatted version
conflict message.
[reinout]
2.3.1 (2014-12-16)
==================
- Fixed: Buildout merged single-version requirements with
version-range requirements in a way that caused it to think there
wasn't a single-version requirement. IOW, buildout throught that
versions were being picked when they weren't.
- Suppress spurios (and possibly non-spurious) version-parsing warnings.
2.3.0 (2014-12-14)
==================
- Buildout is now compatible with (and requires) setuptools 8.
2.2.5 (2014-11-04)
==================
