--------------------

* Bumped the version string in ``virtualenv.py`` up, too.

* Fixed rST rendering bug of long description.

------------------

* Update embedded pip to version 1.1.

* Fix `--relocatable` under Python 3. Thanks Doug Hellmann.

* Added environ PATH modification to activate_this.py. Thanks Doug
Napoleone. Fixes 14.

* Support creating virtualenvs directly from a Python build directory on
Windows. Thanks CBWhiz. Fixes 139.

* Use non-recursive symlinks to fix things up for posix_local install
scheme. Thanks michr.

* Made activate script available for use with msys and cygwin on Windows.
Thanks Greg Haskins, Cliff Xuan, Jonathan Griffin and Doug Napoleone.
Fixes 176.

* Fixed creation of virtualenvs on Windows when Python is not installed for
all users. Thanks Anatoly Techtonik for report and patch and Doug
Napoleone for testing and confirmation. Fixes 87.

* Fixed creation of virtualenvs using -p in installs where some modules
that ought to be in the standard library (e.g. `readline`) are actually
installed in `site-packages` next to `virtualenv.py`. Thanks Greg Haskins
for report and fix. Fixes 167.

* Added activation script for Powershell (signed by Jannis Leidel). Many
thanks to Jason R. Coombs.

----------------

* Gave user-provided ``--extra-search-dir`` priority over default dirs for
finding setuptools/distribute (it already had priority for finding pip).
Thanks Ethan Jucovy.

* Updated embedded Distribute release to 0.6.24. Thanks Alex Gronholm.

* Made ``--no-site-packages`` behavior the default behavior. The
``--no-site-packages`` flag is still permitted, but displays a warning when
used. Thanks Chris McDonough.

* New flag: ``--system-site-packages``; this flag should be passed to get the
previous default global-site-package-including behavior back.

* Added ability to set command options as environment variables and options
in a ``virtualenv.ini`` file.

* Fixed various encoding related issues with paths. Thanks Gunnlaugur Thor Briem.

* Made ``virtualenv.py`` script executable.

------------------

* Restored ability to run on Python 2.4, too.

------------------

* Restored ability to run on Python < 2.7.

------------------

* Updated embedded distribute release to 0.6.19.

* Updated embedded pip release to 1.0.2.

* Fixed 141 - Be smarter about finding pkg_resources when using the
non-default Python interpreter (by using the ``-p`` option).

* Fixed 112 - Fixed path in docs.

* Fixed 109 - Corrected doctests of a Logger method.

* Fixed 118 - Fixed creating virtualenvs on platforms that use the
"posix_local" install scheme, such as Ubuntu with Python 2.7.

* Add missing library to Python 3 virtualenvs (``_dummy_thread``).
