+ Version 0.9 adds a few new firmware features and accompanying
+ AltosUI changes, along with new hardware support.

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