September in Servo: <progress>, rounded rectangles, and more! - Servo aims to empower developers with a lightweight, high-performance alternative for embedding web technologies in applications.

Servo released version 0.7.0 in September, encompassing 527 commits that add web platform features including the `<progress>` element, the `:checked` pseudoclass, the `user-select` property, CSS typed arithmetic, and the `roundRect()` canvas API. The browser engine, positioned as a lightweight, high-performance alternative for embedding web technologies, also upgraded to SpiderMonkey v153.3 and mozangle v0.7, both carrying upstream security fixes, and expanded its WebCrypto support with the MLKEM768-X25519 algorithm. Compatibility gains include a working egui.rs demo and a playable Candy Crush game, while work-in-progress efforts target accessibility tree geometry reporting, WebGL2 conformance, contenteditable-based editors, and video closed captioning. The release matters as a signal of Servo's steady progress toward practical embeddability, with developers invited to report site successes and failures via Zulip and GitHub. Next to watch: completion of the accessibility, WebGL2, and captioning work streams, plus broader real-world compatibility feedback from the developer community.
