July 2026 — Delivered Helium browser support on the Rsbuild server by extending configuration to recognize Helium as a Chromium-based browser, and updated the internal supported browsers list along with English and Chinese documentation. The work is tracked under the core feature: feat(core): support Helium browser (#8034) with commit 5f7a80d6fb21b4672bea0d83009efc3a1e1bdb24.

In April 2026, delivered targeted improvements to source map handling across two core repos (rsbuild and rspack), enhancing debugging, traceability, and build reliability for developer teams. Implementations focused on flexible extraction schemas and robust source map generation, with an emphasis on business value and maintainable tooling.

March 2026 for web-infra-dev/rsbuild focused on enhancing debugging capabilities through Source Map Extraction Enhancement. Delivered an extraction option to pull source maps from matched JavaScript files, enabling inclusion of maps from packages that already provide them. This reduces troubleshooting time and speeds development cycles by making debug information consistently available in built artifacts.

Month: 2026-01 — Stylelint/stylelint: focus on stabilizing GlobbyOptions path handling by implementing a URL-to-filepath conversion utility to fix TypeScript errors and improve configuration reliability. This work reduces misconfigurations and TS compile issues, enabling smoother developer experience and more robust builds.

December 2025 (Month 2025-12) — rsbuild on web-infra-dev delivered three core capabilities and a focused bug fix, enhancing observability, configurability, and developer productivity: 1) Real-time error and warning notifications to clients via asynchronous warnings to the socket server (commit 1c170904cdfcd393f59ea8b33c1dc8c021584363); 2) Rsbuild client log level configurability (dev.client.logLevel) with tests (commit 7f96112e9963968b1882c42da72a8701b519cc79); 3) Gzip size report noise reduction to filter tiny diffs for clearer build reports (commit fb9a3090d138c1531b31f11eb8c3c77f4a427cce).
