It seems entirely appropriate that today's featured open source project should be Pinax.
I gave a talk on Pinax at OSCON this morning and at the end of the talk announced the availability of the first 0.9 alpha.
Pinax 0.5 was our first release. 0.7 represented a response to Pinax's first contact with actually building real sites and included fairly cutting-edge (at the time) use of virtualenv and pip.
The development work since then has come from a lot more experience building websites with Pinax. But while a lot of work has taken place, a lot of people didn't know about it because we went too long without a release.
Today that was rectified. Pinax 0.9a1 is now out and is available as easily as typing "pip install Pinax" (preferably inside a virtual environment)
Brian Rosner did a great write up on the mailing list about 0.9a1.
