+= Release Notes for Version 1.4
+:toc!:
+: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.
