+  - Dbus command `LedWriteBytes` renamed to `SetKeyBacklight`
+  - Dbus command `SetKeyBacklight` will now take a JSON string instead of an array of bytes
+    + Example:
+      ```
+      {
+      "Breathe": {
+        "help": false,
+          "colour": [
+            254,
+            5,
+            171
+          ],
+          "colour2": [
+            0,
+            156,
+            156
+          ],
+          "speed": "High"
+        }
+      }
+      ```
+      note that `help` is unused but required as a side-effect of using `gumdrop`
+      for CLI.
+  - Dbus signal `LedCancelEffect` renamed to `KeyBacklightChanged`
+  - Config file is now in JSON format, and will store only the LED modes that a laptop
+    supports rather than the whole set
