• 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.

  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.

• 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.

• 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.

• 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.

• Make deactivate work on ksh

• 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.

• 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 (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).

• 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.
• 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

• Preserve $PYTHONPATH when calling subprocesses.

0.9.2

• 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.

Fixed packaging of the library.
