The (beta) v5 API has been updated with major changes including:

If an attribute or relationship doesn't exist (ie., is null), that element will no longer be returned in the result. This will result in smaller results transfer sizes and make it easier to read and understand result data.
Compression (gzip) has been enabled on the API server.
All entity meta properties are now returned as entity attributes. Meta is only provided at the top-level of the response data.
The top-level meta data now includes more information about the request and results, including a transactionId that can be used when requesting assistance from RescueGroups.org.
