2026-04 monthly summary focusing on delivering reliability and correctness in HTTP range handling within urbit/urbit. The primary delivery this month addressed a subtle edge-case in range requests, ensuring accurate content delivery by preserving trailing zeroes in the length calculation for HTTP range requests. This improves content streaming accuracy and reduces edge-case failures in partial content responses, contributing to a more robust HTTP serving path and better end-user experience.
