- Version 1.0.1 is a major release, adding support for the TeleMini
- device and lots of new AltosUI features

- Add TeleMini v1.0 support. Firmware images for TeleMini are
- included in AltOS releases.

- Change telemetry to be encoded in multiple 32-byte packets. This
- enables support for TeleMini and other devices without requiring
- further updates to the TeleDongle firmware.
- </para>

-<para>
- Support operation of TeleMetrum with the antenna pointing
- aft. Previous firmware versions required the antenna to be
- pointing upwards, now there is a configuration option allowing
- the antenna to point aft, to aid installation in some airframes.

-<para>
- Ability to disable telemetry. For airframes where an antenna
- just isn't possible, or where radio transmissions might cause
- trouble with other electronics, there's a configuration option
- to disable all telemetry. Note that the board will still
- enable the radio link in idle mode.

- Arbitrary frequency selection. The radios in Altus Metrum
- devices can be programmed to a wide range of frequencies, so
- instead of limiting devices to 10 pre-selected 'channels', the
- new firmware allows the user to choose any frequency in the
- 70cm band. Note that the RF matching circuit on the boards is
- tuned for around 435MHz, so frequencies far from that may
- reduce the available range.

-<para>
- Kalman-filter based flight-tracking. The model based sensor
- fusion approach of a Kalman filter means that AltOS now
- computes apogee much more accurately than before, generally
- within a fraction of a second. In addition, this approach
- allows the baro-only TeleMini device to correctly identify
- Mach transitions, avoiding the error-prone selection of a Mach
- delay.

- <listitem>
-<para>
- Wait for altimeter when using packet mode. Instead of quicly
- timing out when trying to initialize a packet mode
- configuration connection, AltosUI now waits indefinitely for
- the remote device to appear, providing a cancel button should
- the user get bored. This is necessary as the TeleMini can only
- be placed in "Idle" mode if AltosUI is polling it.
- </para>
-</listitem>
- <listitem>
-<para>
- Add main/apogee voltage graphs to the data plot. This provides
- a visual indication if the igniters fail before being fired.
- </para>
-</listitem>
- <listitem>
-<para>
- Scan for altimeter devices by watching the defined telemetry
- frequencies. This avoids the problem of remembering what
- frequency a device was configured to use, which is especially
- important with TeleMini which does not include a USB connection.
- </para>
-</listitem>
- <listitem>
-<para>
- Monitor altimeter state in "Idle" mode. This provides much of
- the information presented in the "Pad" dialog from the Monitor
- Flight command, monitoring the igniters, battery and GPS
- status withing requiring the flight computer to be armed and
- ready for flight.

- Pre-load map images from home. For those launch sites which
- don't provide free Wi-Fi, this allows you to download the
- necessary satellite images given the location of the launch
- site. A list of known launch sites is maintained at
- altusmetrum.org which AltosUI downloads to populate a menu; if
- you've got a launch site not on that list, please send the
- name of it, latitude and longitude along with a link to the
- web site of the controlling club to the altusmetrum mailing list.

- Flight statistics are now displayed in the Graph data
- window. These include max height/speed/accel, average descent
- rates and a few other bits of information. The Graph Data
- window can now be reached from the 'Landed' tab in the Monitor
- Flight window so you can immediately see the results of a
- flight.
