CodeIgniter 3.0.6 Released

CodeIgniter 3.0.6 was released today, with some bug fixes and a minor feature.

Most importantly - it fixes a critical bug where a manually-crafted input could bypass Form Validation rules, so if you're using the Form Validation library, please update your application ASAP!

This is recommended for all users of version 3. Download v3.0.6 now, and we encourage you to read the changelog, and to check the directions for upgrading from a previous version.

Bug fixes address the Form Validation, Session and Migration libraries.
The minor feature is an enhancement to the Cache library.

What will be the alternative to prep_for_form? htmltoentities?
