CodeIgniter.com: New User Guide in Development
The CodeIgniter development team is happy to announce work that's been done on the framework's user guide to help make it even better and easier to find the information you're looking for (now based on the Sphinx documentation generation engine).
There's also been a style redesign in the latest release (here on github) on the development branch of the framework. They warn of a few "bumps" that you might come across in using it, but they're working hard to take care of those quickly. If you'd like to see the new version, check out the nightly build results.
