     * Removed `alert_type` from alert data. Contest, DXpedition and Satellite alerts now give those values in `sig` instead, alongside the existing outdoor activity programmes. Teeeeechnically a breaking change but AlertType is so new I doubt anyone is using it yet, so slipped this one in anyway. Sorry :)
     * Added QRP, RaDAR Rally, /AM and /MM activities
     * Added `has_refs` and `alerts_possible` to Activity data
+    * Added `dx_grid`, `dx_latitude` and `dx_longitude` to alert data
