Jan 1, 2026January 2026 monthly summary for firedancer (firedancer-io/firedancer). Delivered two key features that improve performance, reliability, and compile-time optimization in the network data path. XDP Ring Buffer Management Enhancements introduced helper functions for XDP transmit/fill ring management, improving empty/full state checks and overall packet processing efficiency. Compile-Time FD_ULONG_IS_POW2 Macro added to allow compile-time evaluation of power-of-two checks, enabling potential optimizations and safer code paths. These changes were driven by a bug report from @colinlyguo and are reflected in targeted commits that improve stability under high load.
