+    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.

+      <listitem>
+	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.

+    AltosUI Changes

+      <listitem>
+	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.
+      </listitem>
+      <listitem>
+	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>
+      <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.
