+ 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 New Features +

+ Add support for TeleGPS boards. +
+ 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. +
+ 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 +

+ 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 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. +
+ Increase the width of data lines in the graphs to make them + easier to read. +
+ 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. +
+ 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 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. +
