PWA / Web App Update Methods?

I have been working on a HTML app recently and noticed that for every version I export (HTML) I have to force my browser to reload a fresh version (not a cached version) (by adding a version parameter to the requested URL, or put it in a new directory etc).

As annoying as it is, for dev this was OK. The issue is, this is a targeted mobile PWA and is therefore "added to home screens", so neither of the above can be done. When I update the project the PWA loaded form the home screen does not update.

Is there any methods built in to C3 to force this?

I thought that the project version number would be saved inside sw.js so every time its up revved the sw.js changes and therefore I believe will force a reload, but it does not store it inside sw.js (or anywhere in an HTML export from what I can see)?

EDIT: Just found this, will do some further testing...

So it appears these update functions in the browser object no longer exsist?

The Browser object has two conditions to detect this happening: On update found and On update ready.

I cannot find either of these above?
