virtualenvwrapper is a set of extensions to virtualenv for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies.
New features include pre and post operation hooks for operations involving virtualenvs (so you can do things like install your favorite common packages every time you make a new virtualenv), navigation functions for working inside the environment, and a host of fixes and optimizations. Check the release log on PyPI for a complete history of the updates.
In the ~2 weeks since I’ve uploaded virtualenvwrapper to bitbucket, I’ve received more patches than in all the previous time I maintained the script. Score 1 for DVCS!
