The Web Animations API now supports a number of new features. First, animation.ready and animation.finished. Second, the browser can now clean up and remove outdated animations which save memory and improves performance.

Wake lock is a much-requested feature that prevents a screen from dimming and locking. The feature was previously in developer preview and is now graduating from the origin trial in Chrome 84. This could be a simple feature that has a huge impact. Betty Crocker saw a 300% increase in purchase intent after implementing the feature.
The Content Indexing API allows users to find content that is available offline. Previous indexing features rely on a network connection, which isn’t helpful for content available offline. The offline indexing feature works using metadata. The Content Indexing API is another graduate of origin trial in Chrome 84. Google also announced two new origin trials for Chrome 84 (idle detection and Web Assembly SIMD). Check out the original trial details here.
