+= Release Notes for Version 1.4
+include::release-head.adoc[]
+:doctype: article
+
+	Version 1.4 is a major release. It includes support for our new
+	TeleGPS product, new features and bug fixes in in the flight
+	software for all our boards and the AltosUI ground station
+
+	== AltOS
+
+		AltOS new features:
+
+		* Add support for TeleGPS boards.
+
+		* Make the beeper tone configurable, making it
+		  possible to distinguish between two Altus Metrum
+		  products in the same ebay.
+
+		* Make the firing time for extra pyro channels
+		  configurable, allowing longer (or shorter) than the
+		  default 50ms.  Only relevant for TeleMega at this
+		  time.
+
+		AltOS fixes:
+
+		* Replace the 'dit dit dit' tones at startup with the
+		  current battery voltage, measured in tenths of a
+		  volt. This lets you check the battery voltage
+		  without needing telemetry, which is especially
+		  useful on EasyMini.
+
+		* Change state beeping to "Farnsworth spacing", which
+		  means they're quite a bit faster than before, and so
+		  they take less time to send.
+
+		* Fix bug preventing the selection of the 'Flight
+		  State After' mode in pyro configuration.
+
+		* Fix bug where erasing flights would reset the flight
+		  number to 2 on TeleMega and TeleMetrum v2.
+
+		* Fix u-Blox GPS driver to mark course and speed data
+		  as being present.
+
+	== AltosUI Application
+
+		AltosUI new features:
+
+		* Add zooming and new content types (terrain and road
+		  maps) to map view. Change map storage format from
+		  PNG to Jpeg, which saves a huge amount of disk
+		  space. You will need to re-download all of your
+		  pre-loaded map images.
+
+		* Add a distance measuring device to the maps
+		  view. Select this by using any button other than the
+		  left one, or by pressing shift or control on the
+		  keyboard while using the left button.
+
+		* Add new 'Ignitor' tab to the flight monitor display
+		  for TeleMega's extra ignitors.
+
+		* Add additional ignitor firing marks and voltages to
+		  the graph so you can see when the ignitors fired,
+		  along with the ignitor voltages.
+
+		* Add GPS course, ground speed and climb rate as
+		  optional graph elements.
+
+		AltosUI fixes:
+
+		* When flashing new firmware, re-try opening the
+		  device as sometimes it takes a while for the
+		  underlying operating system to recognize that the
+		  device has rebooted in preparation for the flashing
+		  operation.
+
+		* Hide Tilt Angle in ascent tab for devices that don't
+                  have a gyro.
+
+		* Increase the width of data lines in the graphs to
+		  make them easier to read.
+
+		* Filter out speed and acceleration spikes caused by
+		  ejection charge firing when computing the maximum
+		  values. This provides a more accurate reading of
+		  those maximums.
+
+		* Fix EasyMini voltage displays. Early EasyMini
+		  prototypes used a 3.0V regulator, and AltosUI still
+		  used that value as the basis of the
+		  computation. Production EasyMini boards have always
+		  shipped with a 3.3V regulator. Also, purple EasyMini
+		  boards sensed the battery voltage past the blocking
+		  diode, resulting in a drop of about 150mV from the
+		  true battery voltage. Compensate for that when
+		  displaying the value.
+
+		* Display error message when trying to configure
+		  maximum flight log size while the flight computer
+		  still has flight data stored.
+
+		* Handle TeleMetrum and TeleMini eeprom files
+		  generated with pre-1.0 firmware. Those ancient
+		  versions didn't report the log format, so just use
+		  the product name instead.
+
+	== TeleGPS Application
+
+		* New application designed for use with TeleGPS boards.
+
+		* Shares code with AltosUI, mostly just trimmed down
+		  to focus on TeleGPS-related functions.
+
+	== Documentation
+
+		Documentation changes:
+
+		* Re-create the drill template images; they should
+		  print correctly from Firefox at least. Ship these as
+		  individual PDF files so they're easy to print.
+
+		* Add a description of the 'Apogee Lockout' setting,
+		  which prevents the apogee charge from firing for a
+		  configurable amount of time after boost.
