 Releases 
 ########
 
+v0.7.0
+======
+
+* Fixed BLE data format when sensor is not available. When data is invalid send 0xffff in the ble payload to indicate that.
+* Updated dependencies to latest versions.
+* Fixed battery reading setup
+* Added meta data to mDNS broadcast (app, version, id), used by GravityMon Gateway to map device id towards name when using BLE. 
+* Updated code to use NAN instead of -273 as invalid temperature
+* Split hardware view into hardware and sensor view for better clarity.
+* Updated file view to improve display of device files
+* Added 3d model for a case that fits my PCB.
