Backward Compatibility
All Quadra releases from 4.0.0 guarantee backward compatibility.
Backward compatibility means that any application code (or command lines), developed for release 4.0.0 and onwards, will work with any other subsequent releases (for example 4.4.0). Any firmware from 4.0.0 and onwards will work with any software component from 4.0.0 and onwards, and vice versa.
Parameters are deprecated as opposed to being removed to ensure that each release maintains this backward compatibility for all users. Therefore all deprecated parameters will always continue to work, with any future releases. No deprecated parameters ever break backward compatibility.
