The @w3c MathML Core specification, now at #CandidateRecommendation status, defines a core subset of the #MathML 3 specification designed for reliable, interoperable web browser support. It focuses on mathematical notation rendering, tightly integrating with #HTML, #CSS, and DOM standards to ensure consistency, testability, and minimal implementation complexity. #timetoimplement

@w3c has released "Pointer Events Level 3" as #CandidateRecommendation #timetoimplement
▶️ https://www.w3.org/TR/pointerevents3/

This specification aims to simplify development across diverse input devices like mouse, pen, and touchscreens. Along with expanded #CSS touch-action values, new features include altitudeAngle and azimuthAngle properties for detailed stylus input.

The @w3c Compute Pressure #API specification defines a set of pressure states (e.g. high CPU load) delivered to a #WebApp to signal when adaptation of the workload is appropriate to ensure consistent quality of service. #timetoimplement
▶️ https://www.w3.org/TR/compute-pressure/

The document defines 3 concepts: processing units (such as the CPU), supported sources (such as #GPU), sampling and reporting rates.

Key usage scenarios are described in this explainer: https://github.com/w3c/compute-pressure#readme

The @w3c Timed Text #WorkingGroup invites implementations of the "Dubbing and Audio Description Profiles of TTML2 (DAPT)" specification for exchanging timed text content in #dubbing and #audio description workflows #timetoimplement

▶️ https://www.w3.org/TR/dapt/

DAPT enables scripting, voicing, and mixing for dubbing and audio descriptions, supporting video #localization and #accessibility.

@w3c invites implementations of Controlled Identifiers (CIDs) v1.0

CIDs generalizes the mechanism used to prove control of an identifier in Decentralized Identifiers (#DID), making it also applicable to non-decentralized identifiers and systems (e.g. HTTPS URLs). They can be used with Verifiable Credentials, e.g. to authenticate the subject of such a credential

WebGPU Shading Language (WGSL), the shader language for WebGPU, also reached the @w3c #CandidateRecommendation status
▶️ https://www.w3.org/TR/WGSL/
#timetoimplement

Shaders are the most important when it comes to rendering in WebGPU. WebGPU Shading Language) lets #developers write shaders for draw commands in the render pipeline and dispatch commands in the compute pipeline exposed by #WebGPU.

Better, faster and easier to use!

The @w3c WebGPU #API lets developers use high-performance GPU computing and advanced rendering, offering faster operations and modern GPU support as #WebGL's successor #timetoimplement
▶️ https://www.w3.org/TR/webgpu/

WebGPU opens up new programming possibilities in #browsers.

The @w3c #WebAssembly Core Specification is now a #CandidateRecommendation
▶️ https://www.w3.org/TR/wasm-core-2/
#timetoimplement

This doc. outlines release 2.0 of the core WebAssembly standard, a secure, portable, low-level code format. The update improves #performance, including support for SIMD (Single Instruction Multiple Data) to enhance #parallel processing on compatible #CPUs.

The newly published @w3c #CandidateRecommendation "Device Posture API" allows #WebApps to request and be notified of changes of the posture of a device #timetoimplement
https://www.w3.org/TR/device-posture/

Device posture refers to its physical position, detected via sensors. With foldable devices, understanding posture is key for responsive design, especially when the device isn’t fully flat.

📣 Call for implementations for the W3C Baggage specification which defines a #HTTP header to propagate contextual information as part of a distributed request to enable better observability or better control of the system. #timetoimplement
▶️ https://www.w3.org/TR/2024/CR-baggage-20240530/

Baggage works independently of Trace Context and can be used without Distributed Tracing.
