 *  New: Support the `QUERY` HTTP method. You will need to set the `Request.cacheUrlOverride`
    property to cache calls made with this method. The `RequestBody.sha256()` may be helpful here;
    use it to compose a cache URL from the query body.

 *  New: Publish events when calls must wait to execute. `EventListener.dispatcherQueueStart()`
