Thanks for this request! One question - are you using the setVersion functionality in Raygun4JS to set the version?
One of the reasons we haven't pushed hard on versions outside of iOS/Android is because there's no standard version in JS that we could pick up (i.e. on mobile you can query the version number, but you can't do that in JS). However, customers extending the integration to manage this themselves, using the setVersion function, would absolutely benefit from this capability.
I'm just wanting to check that you are already doing this too?
Appreciate the extra insights here.
