+ Version 1.1.1 is a bug-fix release. It fixes a couple of bugs in
+ AltosUI and one firmware bug that affects TeleMetrum version 1.0
+ boards. Thanks to Bob Brown for help diagnosing the Google Earth
+ file export issue, and for suggesting the addition of the Ground
+ Distance value in the Descent tab.

+ TeleMetrum v1.0 boards use the AT45DB081D flash memory part to
+ store flight data, which is different from later TeleMetrum
+ boards. The AltOS v1.1 driver for this chip couldn't erase
+ memory, leaving it impossible to delete flight data or update
+ configuration values. This bug doesn't affect newer TeleMetrum
+ boards, and it doesn't affect the safety of rockets flying
+ version 1.1 firmware.

+ Creating a Google Earth file (KML) from on-board flight data
+ (EEPROM) would generate an empty file. The code responsible
+ for reading the EEPROM file wasn't ever setting the GPS valid
+ bits, and so the KML export code thought there was no GPS data
+ in the file.

+ The “Landed” tab was displaying all values in metric units,
+ even when AltosUI was configured to display imperial
+ units. Somehow I just missed this tab when doing the units stuff.
+ </listitem>
+ <listitem>
+ The “Descent” tab displays the range to the rocket, which is a
+ combination of the over-the-ground distance to the rockets
+ current latitude/longitude and the height of the rocket. As
+ such, it's useful for knowing how far away the rocket is, but
+ difficult to use when estimating where the rocket might
+ eventually land. A new “Ground Distance” field has been added
+ which displays the distance to a spot right underneath the
+ rocket.

+ <listitem>
+ Sensor data wasn't being displayed for TeleMini flight
+ computers in Monitor Idle mode, including things like battery
+ voltage. The code that picked which kinds of data to fetch
+ from the flight computer was missing a check for TeleMini when
+ deciding whether to fetch the analog sensor data.
