Quick update

Release 0.4 is coming along nicely, a ton of work has been done, loads of features have been added and just a few tickets are open.

Here's a list of new features that have already been completed:

• Programmable mixes (input to input and output to output); master slave mix with separate rates on positive and negative master input, master offset and offset mix.
• Offsets; aka conditional trims
• Hovering adjustments; Trim curves at low, center and high
• Governor; three rates (switch selectable) and throttle hold supported
• AIPin calibration
• Multi engine support; rudder to throttle mixing, throttle cut, throttle idle level
• Trainer port; teacher student mixing, full processing or copy directly to output, per channel settings
• Gimbal classes, supports mode 1, 2, 3 and 4
• Input system for switches, supports 2 and 3 position switches
• Debugging features; asserts, warnings, debug logging using stdio
• UART implementation of stdio; use any stdio function over serial
• Input/output system for channels, PPMIn/Out and ServoIn/Out refactored
• Programmable flight timer; 1 second to 5 hours, count up or down, audible alerts, supports Buzzer and Speaker
• Servo speed (configurable from 0.1 to 10 seconds)

And my todo list:

• Snap roll support
• PCM Transmitter Receiver implementation using nRF24L01+
• Esky compatible Transmitter Receiver implementation using nRF24L01+
• Persistency; save and load settings to/from EEPROM
• Rotary encoder support
• Panning camera
• Switch dead band

Plenty to do, much more done :D
