codeigniter 2.0 documentation?

ajsie: CodeIgniter 2.0 is still in development, therefore it is not finished or ready for proper use.

The documentation for packages and drivers can be seen linked to from the Changelog but these features are still open to change.

There are new upgrade changes made weekly that will affect how your application runs in CodeIgniter 2.0 making it a tricky environment to work with. For example the other day they ripped out the Validation class. Soon they might rename Controller to CI_Controller, etc.

Use 1.7.2 for now, much easier.
