you can disable coloring from the prefererences

the version shown on version tracker is 2.1.0


as this is R for OS X binaries.

On top of R there is R.app, the GUI, whose development  varies at 
different speed (we have daily building thanks to Simon)

If you mean the version tracker utils: it could probably be due to the 
fact that they take versioning information from the R.app signature.

I'll try to understand what's happening as I physically do the update 
every time
