Thanks to the people who found a few small quirks w/ 0.2.4. These issues have been resolved, and I've issued a new release, 0.2.5. Only three files have been changed:
includes/qcodo/qform_objects/_enumerations.inc (to add QCalendarType back in)
includes/qcodo/qform_objects/QFormBase.inc (to add back in support for reading un-enabled controls on an AJAX call) -- incidentally, this fixes the issues with Editable Listbox example
includes/qcodo/qcodo.inc (to update the version to 0.2.5)
Other than these three small chnages, everything else is the same.
