Once this change takes effect, we will handle boolean query parameters in a more explicit way.  For query parameters that are defined as a boolean type in our documentation, the case-insensitive strings true and 1 will be handled as a true value, and the case-insensitive strings false and 0 will be handled as the false value.  Other values will be defaulted to false, if provided.

We didn’t have a clear statement on what the accepted values for boolean query parameters were.
