A round up of the deprecations and removals in Chrome 78 to help you plan.

Fresher service workers, by default

HTTP requests that check for updates to the service worker script will no longer be fulfilled by the HTTP cache by default. This works around a common developer pain point, in which setting an inadvertent Cache-Control: header on your service worker script could lead to delayed updates. Also, updates to imported scripts can trigger the service worker update flow.
