+    Version 1.3.1 is a minor release. It improves support for TeleMega,
+    TeleMetrum v2.0, TeleMini v2.0 and EasyMini.

+	  Improve sensor boot code. If sensors fail to self-test, the
+	  device will still boot up and check for pad/idle modes. If
+	  in idle mode, the device will warn the user with a distinct
+	  beep, if in Pad mode, the unit will operate as best it
+	  can. Also, the Z-axis accelerometer now uses the factory
+	  calibration values instead of re-calibrating on the pad each
+	  time. This avoids accidental boost detect when moving the
+	  device around while in Pad mode.
+	</p></li><li class="listitem"><p>
+	  Fix antenna-down mode accelerometer configuration. Antenna
+	  down mode wasn't working because the accelerometer
+	  calibration values were getting re-computed incorrectly in
+	  inverted mode.
+	</p></li><li class="listitem"><p>
+	  Improved APRS mode. Now uses compressed position format for
+	  smaller data size, improved precision and to include
+	  altitude data as well as latitude and longitude. Also added
+	  battery and pyro voltage reports in the APRS comment field
+	  so you can confirm that the unit is ready for launch.

+	  Display additional TeleMega sensor values in real
+	  units. Make all of these values available for
+	  plotting. Display TeleMega orientation value in the Ascent
+	  and Table tabs.

+	  Support additional TeleMega pyro channels in the Fire
+	  Igniter dialog. This lets you do remote testing of all of
+	  the channels, rather than just Apogee and Main.

+	  Limit data rate when downloading satellite images from
+	  Google to make sure we stay within their limits so that all
