- In TeleMini recovery mode (when booted with the outer two
- debug pins connected together), the radio parameters are also
- set back to defaults (434.550MHz, N0CALL, factory radio cal).
- </listitem>
- <listitem>
- Add support for reflashing the SkyTraq GPS chips. This
- requires special host-side code which currently only exists
- for Linux.

- Correct Kalman filter model error covariance matrix. The
- values used previously assumed continuous measurements instead
- of discrete measurements.

- Fix some bugs in the USB driver for TeleMetrum and TeleDongle
- that affected Windows users.

- AltosUI Changes
- <itemizedlist>
- <listitem>
- Handle missing GPS lock in 'Descent' tab. Previously, if the
- GPS position of the pad was unknown, an exception would be
- raised, breaking the Descent tab contents.
- </listitem>
- <listitem>
- Improve the graph, adding tool-tips to show values near the
- cursor and making the displayed set of values configurable,
- adding all of the flight data as options while leaving the
- default settings alone so that the graph starts by showing
- height, speed and acceleration.
- </listitem>
- <listitem>
- Make the initial position of the AltosUI top level window
- configurable. Along with this change, the other windows will
- pop up at 'sensible' places now, instead of on top of one
- another.
- </listitem>
- <listitem>
- Add callsign to Monitor idle window and connecting
- dialogs. This makes it clear which callsign is being used so
- that the operator will be aware that it must match the flight
- computer value or no communication will work.
- </listitem>
- <listitem>
- When downloading flight data, display the block number so that
- the user has some sense of progress. Unfortunately, we don't
- know how many blocks will need to be downloaded, but at least
- it isn't just sitting there doing nothing for a long time.
- </listitem>
- <listitem>
- Add GPS data and a map to the graph window. This lets you see
- a complete summary of the flight without needing to 'replay'
- the whole thing.
