This Month in Ladybird – March 2026 (ladybird.org)

Ladybird’s March 2026 update reports major progress across the project, including a rewritten Rust regex engine, performance gains to the JavaScript engine, and persistent bookmarks. The team also implemented parts of Media Source Extensions (VP9/WebM and Opus/audio), added new CSS parsing/support features, and parallelized HTML script parsing. In infrastructure work, it removed the legacy LibJS compiler pipeline and overhauled macOS IPC to use Mach ports, while noting continued improvements to Web Platform Tests.
