WebCodecs
Existing media APIs (
HTMLMediaElement,
Media Source Extensions,
WebAudio,
MediaRecorder, and
WebRTC) are high-level and narrowly-focused.
The WebCodecs API eliminates these deficiencies by giving programmers a way to use media components that are already present in the browser. Specifically:
- Video and audio decoders
- Video and audio encoders
- Raw video frames
- Image decoders
WebGPU
The WebGPU API is the successor to the WebGL and WebGL2 graphics APIs for the Web. It provides modern features such as "GPU compute" as well as lower overhead access to GPU hardware and better, more predictable performance. WebGPU exposes modern computer graphics capabilities, specifically Direct3D 12, Metal, and Vulkan, for performing rendering and computation operations on a graphics processing unit (GPU).

Align transform-style: preserve-3d and perspective Property with the Spec
The preserve-3d property allows child elements to participate in the parent's 3D scene, and the perspective property applies a perspective transform to child elements.
Deprecate and Remove WebSQL in Third-Party Contexts
WebSQL in third-party contexts is now deprecated. Removal is expected in Chrome 97. The Web SQL Database standard was first proposed in April 2009 and abandoned in November 2010. Gecko never implemented this feature, and WebKit deprecated it in 2019. The W3C encourages
Web Storage and
Indexed Database for those needing alternatives.
Restrict Private Network Requests for Subresources to Secure Contexts
This is a first step towards fully implementing Private Network Access. Servers running inside local networks, or on a user's device, expose powerful capabilities to the web in ways that can be quite dangerous. Private Network Access proposes a set of changes to limit the impact of requests to these servers by ensuring that the servers are opting-into any communication with external entities.
