In January 2026, delivered a critical dependency compatibility upgrade in oxc-resolver to align with downstream projects and tooling. By bumping pnp from 0.12.7 to 0.12.8 and updating the lockfile, downstream consumers like rolldown can consistently pick up the updated crate, reducing build issues and integration risk.

December 2025 summary for rolldown/rolldown focusing on HMR runtime stabilization improvements. Implemented a robust fix to correctly reference module identifiers for CommonJS modules with no exports during HMR registration, addressing a long-standing bug that could crash in environments lacking a Node-like module object (e.g., React Native). The change ensures each module gets a proper scope via __commonJSMin and registerModule, preventing cross-module export reference sharing. This work reduces runtime errors, improves cross-environment reliability, and enhances developer experience in hot module replacement workflows.

June 2025 monthly summary focused on stability and build reliability for the oxc-resolver crate. The standout achievement was a critical build fix to support Yarn Plug'n'Play (yarn_pnp) by including the pnp_manifest in ResolveOptions, preventing a build failure and smoothing integration with Yarn PnP workflows.

March 2025: Focused on strengthening React Fast Refresh support in swc-project/swc by enhancing typing for configuration options and addressing type safety gaps. Resulted in a safer, more flexible development experience and reduced risk of runtime errors in React refresh workflows.
