 * The methode "cloture" on contract were renamed into "closeAll".
+* The method "is_erasable" of invoice return a value <= 0 if not erasable (value is meaning) instead of always 0.

   __PROPALREF__, ...)
 * The substition key __SIGNATURE__ was renamed into __USER_SIGNATURE__ to follow naming conventions.
