Release Notes: All debug support was dropped, since there were no known developers using it and the removal makes the sources readable again. A few bugs were fixed, including a block replacement bug, the warnings which occurred if error_reporting = E_ALL, the failure when including files from upper directories, and some other minor bugs. Several error handlers were added. A configurable warning level mechanism was added. Yapter now outputs clear error/warning/notice messages when setting a variable was forgotten, instead of presenting the warning provided by PHP.
