+Changes & News
+--------------
+.. warning::
+Python bugfix releases 2.6.8, 2.7.3, 3.1.5 and 3.2.3 include a change that
+will cause "import random" to fail with "cannot import name urandom" on any
+virtualenv created on a Unix host with an earlier release of Python
+2.6/2.7/3.1/3.2, if the underlying system Python is upgraded. This is due to
+the fact that a virtualenv uses the system Python's standard library but
+contains its own copy of the Python interpreter, so an upgrade to the system
+Python results in a mismatch between the version of the Python interpreter
+and the version of the standard library. It can be fixed by removing
+``$ENV/bin/python`` and re-running virtualenv on the same target directory
+with the upgraded Python.
+1.11.4 (2014-02-21)
+~~~~~~~~~~~~~~~~~~~
+* Updated pip to 1.5.4
+1.11.3 (2014-02-20)
+~~~~~~~~~~~~~~~~~~~
+* Updated setuptools to 2.2
+* Updated pip to 1.5.3
+1.11.2 (2014-01-26)
+~~~~~~~~~~~~~~~~~~~
+* Fixed easy_install installed virtualenvs by updated pip to 1.5.2
+1.11.1 (2014-01-20)
+~~~~~~~~~~~~~~~~~~~
+* Fixed an issue where pip and setuptools were not getting installed when using
+the ``--system-site-packages`` flag.
+* Updated setuptools to fix an issue when installed with easy_install
+* Fixed an issue with Python 3.4 and sys.stdout encoding being set to ascii
+* Upgraded pip to v1.5.1
+* Upgraded setuptools to v2.1
+1.11 (2014-01-02)
+~~~~~~~~~~~~~~~~~
+* **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
+1.10.1 (2013-08-07)
+~~~~~~~~~~~~~~~~~~~
+* **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
+1.10 (2013-07-23)
+~~~~~~~~~~~~~~~~~
+* **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
+1.9.1 (2013-03-08)
+~~~~~~~~~~~~~~~~~~
+* 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.
+1.9 (2013-03-07)
+~~~~~~~~~~~~~~~~
+* 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).
+1.8.4 (2012-11-25)
+~~~~~~~~~~~~~~~~~~
+* 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.
+1.8.3 (2012-11-21)
+~~~~~~~~~~~~~~~~~~
+* Fixed readline on OS X. Thanks minrk
+* Updated distribute to 0.6.30 (improves our error reporting, plus new
+distribute features and fixes). Thanks Gabriel (g2p)
+* Added compatibility with multiarch Python (Python 3.3 for example). Added an
+integration test. Thanks Gabriel (g2p)
+* Added ability to install distribute from a user-provided egg, rather than the
+bundled sdist, for better speed. Thanks Paul Moore.
+* Make the creation of lib64 symlink smarter about already-existing symlink,
+and more explicit about full paths. Fixes #334 and #330. Thanks Jeremy Orem.
+* Give lib64 site-dir preference over lib on 64-bit systems, to avoid wrong
+32-bit compiles in the venv. Fixes #328. Thanks Damien Nozay.
+* Fix a bug with prompt-handling in ``activate.csh`` in non-interactive csh
+shells. Fixes #332. Thanks Benjamin Root for report and patch.
+* Make it possible to create a virtualenv from within a Python
+3.3. pyvenv. Thanks Chris McDonough for the report.
+* Add optional --setuptools option to be able to switch to it in case
+distribute is the default (like in Debian).
+1.8.2 (2012-09-06)
+~~~~~~~~~~~~~~~~~~
+* Updated the included pip version to 1.2.1 to fix regressions introduced
+there in 1.2.
+1.8.1 (2012-09-03)
+~~~~~~~~~~~~~~~~~~
+* Fixed distribute version used with `--never-download`. Thanks michr for
+report and patch.
+* Fix creating Python 3.3 based virtualenvs by unsetting the
+``__PYVENV_LAUNCHER__`` environment variable in subprocesses.

+Sajip, Ian Clelland, and Stefan Holek for the report.
+* Fix ``--relocatable`` when a script uses ``__future__`` imports. Thanks
+Branden Rolston.
+* Fix a bug in the config option parser that prevented setting negative
+options with environemnt variables. Thanks Ralf Schmitt.
+* Allow setting ``--no-site-packages`` from the config file.
+* Use ``/usr/bin/multiarch-platform`` if available to figure out the include
+directory. Thanks for the patch, Mika Laitio.
+* Fix ``install_name_tool`` replacement to work on Python 3.X.
+* Handle paths of users' site-packages on Mac OS X correctly when changing
+the prefix.
+* Updated the embedded version of distribute to 0.6.28 and pip to 1.2.
+1.7.2 (2012-06-22)
+~~~~~~~~~~~~~~~~~~
+* Updated to distribute 0.6.27.
+* Fix activate.fish on OS X. Fixes #8. Thanks David Schoonover.
+* Create a virtualenv-x.x script with the Python version when installing, so
+virtualenv for multiple Python versions can be installed to the same
+script location. Thanks Miki Tebeka.
+* Restored ability to create a virtualenv with a path longer than 78
+characters, without breaking creation of virtualenvs with non-ASCII paths.
+Thanks, Bradley Ayers.
+* Added ability to create virtualenvs without having installed Apple's
+developers tools (using an own implementation of ``install_name_tool``).
+Thanks Mike Hommey.
+* Fixed PyPy and Jython support on Windows. Thanks Konstantin Zemlyak.
+* Added pydoc script to ease use. Thanks Marc Abramowitz. Fixes #149.
+* Fixed creating a bootstrap script on Python 3. Thanks Raul Leal. Fixes #280.
+* Fixed inconsistency when having set the ``PYTHONDONTWRITEBYTECODE`` env var
+with the --distribute option or the ``VIRTUALENV_USE_DISTRIBUTE`` env var.
+``VIRTUALENV_USE_DISTRIBUTE`` is now considered again as a legacy alias.
+1.7.1.2 (2012-02-17)
+~~~~~~~~~~~~~~~~~~~~
+* Fixed minor issue in `--relocatable`. Thanks, Cap Petschulat.
+1.7.1.1 (2012-02-16)

+* 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.
+1.7 (2011-11-30)
+~~~~~~~~~~~~~~~~
+* 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.

+* Updated embedded pip release to 1.0.2.
+* Fixed #141 - Be smarter about finding pkg_resources when using the
+non-default Python intepreter (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``).
+1.6.1 (2011-04-30)
+~~~~~~~~~~~~~~~~~~
+* Start to use git-flow.
+* Added support for PyPy 1.5
+* Fixed #121 -- added sanity-checking of the -p argument. Thanks Paul Nasrat.

+* Add fish and csh activate scripts.
+1.4.9
+~~~~~
+* Include pip 0.7.2
+1.4.8
+~~~~~
+* Fix for Mac OS X Framework builds that use
+``--universal-archs=intel``
+* Fix ``activate_this.py`` on Windows.
+* Allow ``$PYTHONHOME`` to be set, so long as you use ``source
+bin/activate`` it will get unset; if you leave it set and do not
+activate the environment it will still break the environment.
+* Include pip 0.7.1
+1.4.7
+~~~~~
+* Include pip 0.7
+1.4.6

+installed
+* Fix problem with ``virtualenv --relocate`` when ``bin/`` has
+subdirectories (e.g., ``bin/.svn/``); from Alan Franzoni.
+* If you set ``$VIRTUALENV_DISTRIBUTE`` then virtualenv will use
+Distribute by default (so you don't have to remember to use
+``--distribute``).
+1.4.3
+~~~~~
+* Include pip 0.6.1
+1.4.2
+~~~~~
+* Fix pip installation on Windows
+* Fix use of stand-alone ``virtualenv.py`` (and boot scripts)
+* Exclude ~/.local (user site-packages) from environments when using
+``--no-site-packages``
+1.4.1
+~~~~~
+* Include pip 0.6
+1.4
+~~~
+* Updated setuptools to 0.6c11
+* Added the --distribute option
+* Fixed packaging problem of support-files
+1.3.4
+~~~~~
+* Virtualenv now copies the actual embedded Python binary on
+Mac OS X to fix a hang on Snow Leopard (10.6).
+* Fail more gracefully on Windows when ``win32api`` is not installed.
+* Fix site-packages taking precedent over Jython's ``__classpath__``
+and also specially handle the new ``__pyclasspath__`` entry in
+``sys.path``.
+* Now copies Jython's ``registry`` file to the virtualenv if it exists.
+* Better find libraries when compiling extensions on Windows.
+* Create ``Scripts\pythonw.exe`` on Windows.
+* Added support for the Debian/Ubuntu
+``/usr/lib/pythonX.Y/dist-packages`` directory.
+* Set ``distutils.sysconfig.get_config_vars()['LIBDIR']`` (based on
+``sys.real_prefix``) which is reported to help building on Windows.
+* Make ``deactivate`` work on ksh
+* Fixes for ``--python``: make it work with ``--relocatable`` and the
+symlink created to the exact Python version.
+1.3.3
+~~~~~
+* Use Windows newlines in ``activate.bat``, which has been reported to help
+when using non-ASCII directory names.
+* Fixed compatibility with Jython 2.5b1.
+* Added a function ``virtualenv.install_python`` for more fine-grained
+access to what ``virtualenv.create_environment`` does.
+* Fix `a problem <https://bugs.launchpad.net/virtualenv/+bug/241581>`_
+with Windows and paths that contain spaces.
+* If ``/path/to/env/.pydistutils.cfg`` exists (or
+``/path/to/env/pydistutils.cfg`` on Windows systems) then ignore
+``~/.pydistutils.cfg`` and use that other file instead.
+* Fix ` a problem
+<https://bugs.launchpad.net/virtualenv/+bug/340050>`_ picking up
+some ``.so`` libraries in ``/usr/local``.
+1.3.2
+~~~~~
+* Remove the ``[install] prefix = ...`` setting from the virtualenv
+``distutils.cfg`` -- this has been causing problems for a lot of
+people, in rather obscure ways.
+* If you use a boot script it will attempt to import ``virtualenv``
+and find a pre-downloaded Setuptools egg using that.
+* Added platform-specific paths, like ``/usr/lib/pythonX.Y/plat-linux2``
+1.3.1
+~~~~~
+* Real Python 2.6 compatibility.  Backported the Python 2.6 updates to
+``site.py``, including `user directories
+<http://docs.python.org/dev/whatsnew/2.6.html#pep-370-per-user-site-packages-directory>`_
+(this means older versions of Python will support user directories,
+whether intended or not).
+* Always set ``[install] prefix`` in ``distutils.cfg`` -- previously
+on some platforms where a system-wide ``distutils.cfg`` was present
+with a ``prefix`` setting, packages would be installed globally
+(usually in ``/usr/local/lib/pythonX.Y/site-packages``).
+* Sometimes Cygwin seems to leave ``.exe`` off ``sys.executable``; a
+workaround is added.
+* Fix ``--python`` option.
+* Fixed handling of Jython environments that use a
+jython-complete.jar.
+1.3
+~~~
+* Update to Setuptools 0.6c9
+* Added an option ``virtualenv --relocatable EXISTING_ENV``, which
+will make an existing environment "relocatable" -- the paths will
+not be absolute in scripts, ``.egg-info`` and ``.pth`` files.  This
+may assist in building environments that can be moved and copied.
+You have to run this *after* any new packages installed.
+* Added ``bin/activate_this.py``, a file you can use like
+``execfile("path_to/activate_this.py",
+dict(__file__="path_to/activate_this.py"))`` -- this will activate
+the environment in place, similar to what `the mod_wsgi example
+does <http://code.google.com/p/modwsgi/wiki/VirtualEnvironments>`_.
+* For Mac framework builds of Python, the site-packages directory
+``/Library/Python/X.Y/site-packages`` is added to ``sys.path``, from
+Andrea Rech.
+* Some platform-specific modules in Macs are added to the path now
+(``plat-darwin/``, ``plat-mac/``, ``plat-mac/lib-scriptpackages``),
+from Andrea Rech.
+* Fixed a small Bashism in the ``bin/activate`` shell script.
+* Added ``__future__`` to the list of required modules, for Python
+2.3.  You'll still need to backport your own ``subprocess`` module.
+* Fixed the ``__classpath__`` entry in Jython's ``sys.path`` taking
+precedent over virtualenv's libs.
+1.2
+~~~
+* Added a ``--python`` option to select the Python interpreter.
+* Add ``warnings`` to the modules copied over, for Python 2.6 support.
+* Add ``sets`` to the module copied over for Python 2.3 (though Python
+2.3 still probably doesn't work).
+1.1.1
+~~~~~
+* Added support for Jython 2.5.
+1.1
+~~~
+* Added support for Python 2.6.
+* Fix a problem with missing ``DLLs/zlib.pyd`` on Windows.  Create
+* ``bin/python`` (or ``bin/python.exe``) even when you run virtualenv
+with an interpreter named, e.g., ``python2.4``
+* Fix MacPorts Python
+* Added --unzip-setuptools option
+* Update to Setuptools 0.6c8
+* If the current directory is not writable, run ez_setup.py in ``/tmp``
+* Copy or symlink over the ``include`` directory so that packages will
+more consistently compile.
+1.0
+~~~
+* Fix build on systems that use ``/usr/lib64``, distinct from
+``/usr/lib`` (specifically CentOS x64).
+* Fixed bug in ``--clear``.
+* Fixed typos in ``deactivate.bat``.
+* Preserve ``$PYTHONPATH`` when calling subprocesses.
+0.9.2
+~~~~~
+* Fix include dir copying on Windows (makes compiling possible).
+* Include the main ``lib-tk`` in the path.
+* Patch ``distutils.sysconfig``: ``get_python_inc`` and
+``get_python_lib`` to point to the global locations.
+* Install ``distutils.cfg`` before Setuptools, so that system
+customizations of ``distutils.cfg`` won't effect the installation.
+* Add ``bin/pythonX.Y`` to the virtualenv (in addition to
+``bin/python``).
+* Fixed an issue with Mac Framework Python builds, and absolute paths
+(from Ronald Oussoren).
+0.9.1
+~~~~~
+* Improve ability to create a virtualenv from inside a virtualenv.
+* Fix a little bug in ``bin/activate``.
+* Actually get ``distutils.cfg`` to work reliably.
+0.9
+~~~
+* Added ``lib-dynload`` and ``config`` to things that need to be
+copied over in an environment.
+* Copy over or symlink the ``include`` directory, so that you can
+build packages that need the C headers.
+* Include a ``distutils`` package, so you can locally update
+``distutils.cfg`` (in ``lib/pythonX.Y/distutils/distutils.cfg``).
+* Better avoid downloading Setuptools, and hitting PyPI on environment
+creation.
+* Fix a problem creating a ``lib64/`` directory.
+* Should work on MacOSX Framework builds (the default Python
+installations on Mac).  Thanks to Ronald Oussoren.
+0.8.4
+~~~~~
+* Windows installs would sometimes give errors about ``sys.prefix`` that
+were inaccurate.
+* Slightly prettier output.
+0.8.3
+~~~~~
+* Added support for Windows.
+0.8.2
+~~~~~
+* Give a better warning if you are on an unsupported platform (Mac
+Framework Pythons, and Windows).
+* Give error about running while inside a workingenv.
+* Give better error message about Python 2.3.
+0.8.1
+~~~~~
+Fixed packaging of the library.
+0.8
+~~~
+Initial release.  Everything is changed and new!
