-If you need to debug code on an Altus Metrum product, you may want our special
-version of SDCC containing a highly modified sdcdb with support for the cc1111
-debugging interface, which you can find on [git.gag.com](http://git.gag.com)
-in the project [fw/sdcc](http://git.gag.com/?p=fw/sdcc;a=summary). This is
-not necessary if you just want to rebuild AltOS and use it.

-### Version 0.8 Features ###
-
-Version 0.8 offers a major upgrade in the AltosUI
-interface. Significant new features include:
-
-* Post-flight graphing tool. This lets you explore the behaviour of
- your rocket after flight with a scroll-able and zoom-able chart
- showing the altitude, speed and acceleration of the airframe along
- with events recorded by the flight computer. You can export graphs
- to PNG files, or print them directly.
-
-* Real-time moving map which overlays the in-progress flight on
- satellite imagery fetched from
- [Google Maps](http://maps.google.com). This lets you see in pictures
- where your rocket has landed, allowing you to plan recovery
- activities more accurately.
-
-* Wireless recovery system testing. Prep your rocket for flight and test
- fire the deployment charges to make sure things work as
- expected. All without threading wires through holes in your
- airframe.
-
-* Optimized flight status displays. Each flight state now has it's own
- custom 'tab' in the flight monitoring window so you can focus on the
- most important details. Pre-flight, the system shows a set of
- red/green status indicators for battery voltage, apogee/main igniter
- continutity and GPS reception. Wait until they're all green and your
- rocket is ready for flight. There are also tabs for ascent, descent
- and landing along with the original tabular view of the data.
-
-* Monitor multiple flights simultaneously. If you have more than one
- TeleDongle, you can monitor a flight with each one on the same
- computer.
-
-* Automatic flight monitoring at startup. Plug TeleDongle into the
- machine before starting AltosUI and it will automatically connect to
- it and prepare to monitor a flight.
-
-* Exports Google Earth flight tracks. Using the Keyhole Markup
- Language (.kml) file format, this provides a 3D view of your rocket
- flight through the Google Earth program.
-
-### Version 0.7.1 Features ###
-
-Version 0.7.1 is the first release containing our new cross-platform Java-based user interface. AltosUI can:
-
-* Receive and log telemetry from a connected TeleDongle device. All data
- received is saved to log files named with the current date and the connected
- rocket serial and flight numbers. There is no mode in which telemetry data
- will not be saved.
-
-* Download logged data from TeleMetrum devices, either through a direct USB
- connection or over the air through a TeleDongle device.
-
-* Configure a TeleMetrum device, setting the radio channel, callsign, apogee
- delay and main deploy height. This can be done through either a USB
- connection or over a radio link via a TeleDongle device.
-
-* Replay a flight in real-time. This takes a saved telemetry log or eeprom
- download and replays it through the user interface so you can relive your
- favorite rocket flights.
-
-* Reprogram Altus Metrum devices. Using an Altus Metrum device connected via
- USB, another Altus Metrum device can be reprogrammed using the supplied
- programming cable between the two devices.
-
-* Export Flight data to a comma-separated-values file. This takes either
- telemetry or on-board flight data and generates data suitable for use in
- external applications. All data is exported using standard units so that no
- device-specific knowledge is needed to handle the data.
-
-* Speak to you during the flight. Instead of spending the flight hunched over
- your laptop looking at the screen, enjoy the view while the computer tells
- you what’s going on up there. During ascent, you hear the current flight
- state and altitude information. During descent, you get azimuth, elevation
- and range information to try and help you find your rocket in the air. Once
- on the ground, the direction and distance are reported.
-
-AltosUI provides all of these features on the three target operating systems,
-Linux, Mac OS X (version 10.5 or newer) and Windows (XP, Vista or 7). The bulk
-of the software is written in Java and is built once and tested and delivered
-on all three target platforms. A tiny ‘shim’ library is built on each system
-to provide access to the Altus Metrum devices connected over the USB link.
