This major version includes many new features (phrasing, accentuation, ornamentation...). The language syntax has been simplified as much as possible. A more complete management of midi exports allows to pilot all your synthetizer parameters, while preserving the natural approach of the language.
The online reference documentation has been updated to reflect this changes. See http://www.compo-music.net/en/reference.php
