I finally found time to release six 1.0.0. six is a Python 2 and 3 compatibility library. You can find the documentation and download it on PyPI.
There haven't been many changes since the beta: one bugfix and one new advanced feature. The bugfix is that unicode escapes are now properly decoded with the u() fake literal in both Python 2 and 3. The feature is that there is now an api for adding items to the "six.moves" interface. This was requested by ActiveState, which uses six in the ActivePython package manager.
