+= Release Notes for Version 1.3.1
+:toc!:
+:doctype: article
+
+ Version 1.3.1 is a minor release. It improves support for
+ TeleMega, TeleMetrum v2.0, TeleMini v2.0 and EasyMini.
+
+ == AltOS
+
+ AltOS new features:
+
+ * 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.
+
+ AltOS fixes:
+
+ * 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.
+
+ * 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.
+
+ == AltosUI Application
+
+ AltosUI new features:
+
+ * 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.
+
+ AltosUI fixes:
+
+ * Limit data rate when downloading satellite images
+ from Google to make sure we stay within their limits
+ so that all of the map tiles download successfully.
