4.6.0.5 is now live, which supports the recent (28 Feb 2017) changes to Raceroom's shared memory. This update adds new time sounds (less robotic), a simple Help page, revised controller handling (the app only scans for controllers when you press the 'scan' button, and remembers them for the next session), improved start up time, and a huge update to RFactor2 functionality (yellow flags, caution periods, many other improvements).
There are a ton of changes 'under the hood' so there's always a risk that something's been broken - give me a kick and I'll give you a fix
