+= Release Notes for Version 1.0.1
+:toc!:
+:doctype: article
+
+ Version 1.0.1 is a major release, adding support for the
+ TeleMini device and lots of new AltosUI features
+
+ == AltOS
+
+ AltOS New Features
+
+ * Add TeleMini v1.0 support.
+
+ * 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.
+
+ * 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.
+
+
+ AltOS Fixes
+
+ * 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.
+
+ * 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.
+
+
+ == AltosUI Application
+
+ AltosUI New Features
+
+ * Add main/apogee voltage graphs to the data
+ plot. This provides a visual indication if the
+ igniters fail before being fired.
+
+ * 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.
+
+ * 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.
+
+ AltosUI Changes
+
+ * 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.
