Release Notes: This release includes the largest cleanup of tag class and method names in the history of the APF. The APF parser is now able to resolve nested structures of tags with the same prefix and name within one document or a file. This new release includes full support for PHP's APF extension, which can accelerate applications by a factor of 4-5. The Logger has been redesigned from the scratch. The state model of APF form controls has been given a visibility indicator to hide form fields and their dependent controls programmatically.
