- Removed method ``is_numeric()`` as it exists as a native PHP function and ``_execute()`` will find and use that (the **is_numeric** rule itself is deprecated since 1.6.1).
- Native PHP functions used as rules can now accept an additional parameter, other than the data itself.
- Updated method ``set_rules()`` to accept an array of rules as well as a string.
+ - Added support for ``in`` method that test if a given value is within a given list.
- Fields that have empty rules set no longer run through validation (and therefore are not considered erroneous).
- Added rule **differs** to check if the value of a field differs from the value of another field.
- Added rule **valid_url**.
