Going a little further than just JPEG-XR - definitely do performance tests for new releases. We had a bug that affected one page in our app. It made people cringe using the feature set that invoked it, but essentially something in angular was firing, and the thing it did caused a re-fire. It just kept looping when on these very specific pages in the app. I finally found it and killed it. But definitely don't go to production with a client CPU murdering bug. It can't be measured the same as network latency, etc... so you really need to use your apps. I was surprised to see a post from Trivago - I might have to book my next hotel through them.
