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.
