+ * Don't require USB OTG support. This kept the latest
+ AltosDroid from being offered on devices without USB device
+ support, although it can work without that just fine using
+ BlueTooth.
+
+ * Don't require bluetooth to be enabled. This allows the
+ application to operate with USB devices or just show old
+ data without turning on the bluetooth radio.
+
+ * Recover old tracker positions when restarting
+ application. This finally allows you to safely stop and
+ restart the application without losing the last known
+ location of any tracker.
