Next Js Daily: Error Responses Get Honest
A cluster of fixes from one contributor corrects Next.js error handling so malformed requests, cache misses, and header conflicts return the right status codes instead of masking them as server errors. Meanwhile, Turbopack's HMR and task-storage internals saw substantial reliability and performance work.

A malformed Server Action body used to return a 500 with a JSON parsing error logged — now it correctly responds 400, per PR…
Second theme: Turbopack reliability and performance is getting serious attention. Will Binns-Smith's PR 97966 fixes HMR losing sync after a dropped connection, now comparing hashes and forcing a reload when stale. His companion PR 96566 makes server HMR demand-driven instead of eager, reducing wasted compilation.…
Third: image optimization stability. Eps1lon's backports (97954, 97949) re-enable AVIF optimization behind a runtime libheif version guard, protecting older Node versions from a known sharp vulnerability path, while styfle's PR 98060 quietly cleans up now-dead fallback code in the same optimizer.
