Good morning. This is Next.js Daily for May 20th, 2026.
Niklas Mischkulnig merged a fix for Turbopack subpath imports pointing to external packages, resolving issues where the imports field wasn't properly handling external package mappings according to Node.js specifications.
Luke Sandberg improved error reporting when webpack loaders crash in Turbopack. The new implementation captures stdout and stderr from crashed processes, provides clearer error messages with loader names, and prevents cascading failures in the issue formatter.
Josh Story enabled rootParams by default, removing the experimental flag. The feature remains limited for route handlers and Server Actions, with expanded support planned for future releases.
Sandberg also optimized memory usage by stopping the pinning of compiled chunk sources on EcmascriptBuildNodeChunkVersion. This change reduces memory consumption by approximately 1.1 gigabytes in warm builds and eliminates unnecessary recomputations during warm restarts.
Niklas Mischkulnig added instrumentationClientInject to Next.js configuration, allowing client bootstrap code injection through next.config.js without modifying user source files.
