Belongs on GAE has always been supported. The cited code in version 2.7.4 is
def BELONGS(self,first,second=None):
if not isinstance(second,(list, tuple)):
raise SyntaxError("Not supported")
...
So perhaps you are passing something to belongs which is not a list or
tuple. It is possible that in the past we did not check.
