🎉 What's New?

workbox-build

• When using the generateSW option to build your service worker, a message listener is now added to the service worker output, which allows you to invoke skipWaiting() from the window via postMessage() [#1929].

🐛 What's Fixed?

workbox-window

• When calling messageSW() after an updated service worker is found, it would send the message to the service worker currently controlling the page. This has been fixed [#1941].

workbox-precaching

• Plugins implementing the cacheDidUpdate method were not properly bound, and would fail in some cases. This has been fixed [#1678].

workbox-background-sync

• If requests were added to a backgroundSync.Queue queue due to server error rather than network error, those requests would be retried immediately, which could lead to an infinite loop. This has been fixed [#1943]

• The backgroundSync.Queue class used to store Request bodies as Blob objects in IndexedDB, but this does not work in Safari. All request bodies are now stored as ArrayBuffer objects [#1932].

workbox-broadcast-update

• If the the BroadcastCacheUpdate instance is passed an install event (which happens when using it as a precache plugin) rather than a fetch event, it would error. This has been fixed [#1938].
