Steven, I was able to confirm with development that our current implementation of SignalR CAN be upgraded to the newest release (which includes JQuery 3) and so we're going to add a feature request now to have this addressed in the future. Unfortunately though it may be some time before this gets looked at as it may require significant research and testing for proper implementation as there are some components no longer available in the latest SignalR releases that we may leverage in SmarterTrack. So this may not happen quickly, but it is on the list! Hope this helps Steven. Have a great rest of your week!
