Dec 1, 2024

December 2024 was a lean but impactful month across gofiber/fiber and armbian/build. Key focus areas centered on future-proofing, performance, and broader hardware support. In gofiber/fiber, we upgraded the codebase to Go 1.23 minimum, introduced iterator-based accessors for client-side resources, and refactored parsing to improve efficiency, with accompanying documentation and tests. We also expanded parsing capabilities with external XML decoders and more robust multipart binding, fixing known issues around EnableSplittingOnParsers and square-bracket notation. In armbian/build, we extended hardware coverage with AP6275P WiFi on Orange Pi 5B, USB3 support for NanoPi R6, and HDMI1 output on Orange Pi 5 Plus, backed by kernel/DT patches to improve stability and interoperability. These changes reduce maintenance burden, accelerate feature delivery, and enable customers to deploy newer Go-powered services and edge devices with greater reliability.
