1.3

• Changed the visibility of isValidPath() . Also, added a phpdoc to warn about subclassing and overriding this method. To re-iterate, the .zip file is untrusted input. We check for absolute path (i.e., leading slash), possible directory traversal attack (i.e., '..'), and use of PHP wrappers (i.e., ':').
• Added an optional $continueOnError parameter to the extract() method. For backward compatibility, it defaults to false.
