The Servo open-source browser engine is out with their September 2025 development highlights. This Rust-based browser engine originally started by Mozilla continues making steady progress as well as to the "servoshell" demo/example browser implementation.

Servoshell added a new "experimental mode" button to turn on experimental engine features. This button is an alternative to using the "--enable-experimental-web-platform-features" command line argument. All engine features including incomplete and experimental features are then enabled.

Servoshell has also landed improvements to its single-process mode and other performance work over the course of September.

Meanwhile Servo's Trusted Types API is now considered stable, Servo now supports Zstd content encoding (Content-Encoding: zstd), DOM exceptions can now have error messages, and more.

Servo has also advanced its embedding support for those wanting to embed Servo into other applications as an alternative to the Chromium CEF.

In case you missed it from a few days ago, [2]Servo 0.0.1 was released too as another advancement past September for this open-source browser engine.
