0.6.4 has been released.
- A Django Scanner,
- a new theme based on GitHub's syntax highlighting,
- you can now use border-radius on the Luminous div element, and it should look okay,
- a whole bunch of bug fixes in web language scanners, and some missing keywords added for Python
Everyone should definitely upgrade as the fixed bugs in the web languages were potentially fatal, although I'm not sure they were reachable.
