New version of the Arduino IDE was released a couple of days ago.
I've already had several customers complain because they tried to use it to run sample code written when 0022 was the newest.
I've now updated my product support site with new versions of Ken Shirriff's "IR remote" library and the timer 5 version of it "IR remote5" that RobotFreak modified.
I've compiled several sketches using various libraries, no problems. It's only a minor, bug fix update so I don't expect it to break libraries.
