PlusWorkflow provides backward compatibility in the areas of:- PlusWorkflow API (Java API, JavaScript API, REST API)
- database schema (only adding new columns is allowed)
- old classes (you can't delete/modify the method or operation of any class coming from the old system - before version 3.1.0)
The system does not provide compatibility at the level of:- DOM structure of HTML pages (form and other pages)
- new classes outside the API (added in the system since version 3.1.0)
- direct use of external Java and JS libraries (ExtJS, jQuery, etc.)
