No, you didnt missed anything. It all about what you see in changelog. And several trivial things at the link i mention above, just quoted some of them :

-All core class names are prefixed with "CI_". Be careful what you extend.

-All core classes now use the __construct convention. Update your constructor calls!

-CI_Base has been removed, the super object now starts at CI_Controller.

-The compat file and compatibility helper have been removed. PHP 5.1.6 supports all the functions they provided.
