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

* **BACKWARDS INCOMPATIBLE** Switched to using wheels for the bundled copies of
setuptools and pip. Using sdists is no longer supported - users supplying
their own versions of pip/setuptools will need to provide wheels.
* **BACKWARDS INCOMPATIBLE** Modified the handling of ``--extra-search-dirs``.
This option now works like pip's ``--find-links`` option, in that it adds
extra directories to search for compatible wheels for pip and setuptools.
The actual wheel selected is chosen based on version and compatibility, using
the same algorithm as ``pip install setuptools``.
* Fixed 495, --always-copy was failing (PR 511)
* Upgraded pip to v1.5
* Upgraded setuptools to v1.4

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

* **New Signing Key** Release 1.10.1 is using a different key than normal with
fingerprint: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
* Upgraded pip to v1.4.1
* Upgraded setuptools to v0.9.8

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

* **BACKWARDS INCOMPATIBLE** Dropped support for Python 2.5. The minimum
supported Python version is now Python 2.6.

* **BACKWARDS INCOMPATIBLE** Using ``virtualenv.py`` as an isolated script
(i.e. without an associated ``virtualenv_support`` directory) is no longer
supported for security reasons and will fail with an error.

Along with this, ``--never-download`` is now always pinned to ``True``, and
is only being maintained in the short term for backward compatibility
(Pull 412).

* **IMPORTANT** Switched to the new setuptools (v0.9.7) which has been merged
with Distribute_ again and works for Python 2 and 3 with one codebase.
The ``--distribute`` and ``--setuptools`` options are now no-op.

* Updated to pip 1.4.

* Added support for PyPy3k

* Added the option to use a version number with the ``-p`` option to get the
system copy of that Python version (Windows only)

* Removed embedded ``ez_setup.py``, ``distribute_setup.py`` and
``distribute_from_egg.py`` files as part of switching to merged setuptools.

* Fixed ``--relocatable`` to work better on Windows.

* Fixed issue with readline on Windows.

.. _Distribute: https://pypi.python.org/pypi/distribute

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

* Updated to pip 1.3.1 that fixed a major backward incompatible change of
parsing URLs to externally hosted packages that got accidentily included
in pip 1.3.

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

* Unset VIRTUAL_ENV environment variable in deactivate.bat (Pull 364)
* Upgraded distribute to 0.6.34.
* Added ``--no-setuptools`` and ``--no-pip`` options (Pull 336).
* Fixed Issue 373. virtualenv-1.8.4 was failing in cygwin (Pull 382).
* Fixed Issue 378. virtualenv is now "multiarch" aware on debian/ubuntu (Pull 379).
* Fixed issue with readline module path on pypy and OSX (Pull 374).
* Made 64bit detection compatible with Python 2.5 (Pull 393).

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

* Updated distribute to 0.6.31. This fixes 359 (numpy install regression) on
UTF-8 platforms, and provides a workaround on other platforms:
``PYTHONIOENCODING=utf8 pip install numpy``.

* When installing virtualenv via curl, don't forget to filter out arguments
the distribute setup script won't understand. Fixes 358.

* Added some more integration tests.

* Removed the unsupported embedded setuptools egg for Python 2.4 to reduce
file size.
