+### Version 0.9 Features ###
+
+Version 0.9 adds a few new firmware features and accompanying AltosUI
+changes, along with new hardware support.
+
+ * Support for TeleMetrum v1.1 hardware. Sources for the flash memory
+   part used in v1.0 dried up, so v1.1 uses a different part which
+   required a new driver and support for explicit flight log erasing.
+
+ * Multiple flight log support. This stores more than one flight log
+   in the on-board flash memory. It also requires the user to
+   explicitly erase flights so that you won't lose flight logs just
+   because you fly the same board twice in one day.
+
+ * Telemetry support for devices with serial number >= 256. Previous
+   versions used a telemetry packet format that provided only 8 bits
+   for the device serial number. This change requires that both ends
+   of the telemetry link be running the 0.9 firmware or they will not
+   communicate.
