This is huge for the progress of WASM
> Added support for growable SharedArrayBuffer.
Not a headliner feature, but a pretty important one for JS/WASM interactions.
> Added support for AVIF on macOS Monterey and macOS Big Sur.
> Added support for the AV1 codec in the MediaCapabilities API.
> Added WebRTC support for hardware AV1 decoding on supported device configurations.
Could this be the first indication of Apple warming to AV1?
> Added support for the Notification API in dedicated workers.
> Added support for Service Workers and Shared Workers to the Permissions API.
> Added support for the termination of nested workers.
Nice to see web workers finally getting some love

A great feature and should help with performance from not having to do constant number->string->number
