@wlbragg @dany93 @Juanvvc Anything that should be added to the list?

[geoffmcl]

@onox could add -

• Added tooltips to all KAP140 autopilot buttons.
• Removed tooltips from all 'not changeable' items, except magnetic compass.
• Added 'expert' mode for a full manual start. ie no autostart settings done...

or some such wording...

I have already written "Small improvements to instruments in radio stack".

[onox]

Added the release notes to version/3.6.0.

Need to add skis now.

[onox]

Ski's will be added to release notes of 2016.1.

Oh, OK. Not paying attention on my part.
