What is new

• Possible BC - Parsing call was moved from ExpressionDescriptor.get_description to ExpressionDescriptor.__init__ that means parsing exceptions are thrown when calling ExpressionDescriptor constructor and not when calling ExpressionDescriptor.get_description modify your exception handling accordingly...
• Possible BC - Option throw_exception_on_parse_error (boolean) was removed, code now works as if throw_exception_on_parse_error=True (default - always throw exceptions). Remove throw_exception_on_parse_error option from your code if you were using it.
