CodeIgniter 2.0.2 and compatable libraries

[eluser]Unknown[/eluser]
Hi there,

I've just decided to start using CodeIgniter over CakePHP, but I'm running into some frustrating problems.

Namely which libraries/plugins etc are compatible with CodeIgniter 2.0.2

I've done some research and have tried to use DX auth as my authentication library... which isn't going to work without seriously modifying the code.

So I've now done more research but can't seem to find a way to tell which libraries are compatible and which aren't.

Should I just be using 1.7?

any guidance would be greatly appreciated
