News, Reviews & Betas which includes large community peer support Google Chrome 99 will be rolling out generally too. It packs improved support for Progressive Web Apps (PWAs), gaming, and a JavaScript specification change that has been debated since 2018.
Chrome 98 landed a month ago and since the Stable release channel shifted to a four-week release cadence recently, it is now time for Chrome 99 to ship. There aren’t a whole bunch of new features present in this build, but that makes sense given that Google is very close to the Chrome 100 milestone. For starters, Chrome 99 will change the implementation of the JavaScript (JS) adoptedStyleSheets specification. This previously used the FrozenArray backing array but will now leverage ObservableArray. The new methods will make it easier to mutate JS arrays. While this is all quite technical, the arguably interesting thing for our readers would be that changes to this specification have been debated between Microsoft, Mozilla, Apple, and Google since 2018. As it currently stands, Google will go ahead and implement this in Chrome 99. It is supported by both Mozilla and Microsoft. On the other hand, we have Apple’s WebKit team which is refusing to support the change in implementation, noting that there’s no worthwhile benefit to it.
