kses 0.2.1 out now

kses is an HTML/XHTML filter written in PHP. It removes all unwanted HTML elements and attributes, and it also does several checks on attribute values. kses can be used to avoid Cross-Site Scripting (XSS), Buffer Overflows and Denial of Service attacks.

The 0.2.1 release adds a new object-oriented version of kses, three new attribute value checks (minlen, minval and valueless), a work-around for an Opera "feature" that treats chr(173) as whitespace, and some other minor changes.
