0.3:
API CHANGE Changed MultiFormStep::$next_steps to public, and MultiFormStep::$is_final_step to public
API CHANGE MultiForm::$start_step is now declared as public, not protected, due to changes in Object::get_static()
ENHANCEMENT Custom text for back/next and submit buttons on a per-step basis
BUGFIX Checking $this->Data exists before trying to unserialize it
BUGFIX #4480 MultiForm::next() and MultiForm::prev() now save the form data before checking the next or previous step
API CHANGE Added currentSessionHash property to MultiForm which stores the currently opened session by the user
API CHANGE Renamed MultiForm::getSessionRecord() to getCurrentSession() and removed the parameter, since this wasn't done in a very OOP manner
ENHANCEMENT: enabled MultiForm to use customised action (actions_exempt_from_validation).
Changed has been done in the constructor to read the static variables (incl. overwritten variables).
BUGFIX: MultiFormStep::saveInto() needs the current Controller as the new $form Controller to work
ENHANCEMENT Added language files
BUGFIX If the step doesn't exist, don't attempt to delete it
BUGFIX Ensure that any relations to MultiFormStep are destroyed before calling delete()
ENHANCEMENT Removed hack of specific action to bypass validation and allow specifying actions to be exempt through a public static variable
0.2:
- ENHANCEMENT Updated entities and added german translation for multiform
- ENHANCEMENT Making multiform module translatable
- ENHANCEMENT Added MultiFormStep->saveInto() to simulate Form->saveInto()
