Major Changes

• TBD

Upgrade Guide

• COM_ARM_TRAFF has been replaced by COM_TRAFF_AVOID. The old value 3 ("enforce for mission modes only") is migrated to COM_TRAFF_AVOID=2, which blocks arming in all modes, not just mission modes. If you relied on being able to arm manually with traffic detected, set COM_TRAFF_AVOID=1 (warning only) instead.

Other changes

• Fast mission Return modes (RTL_TYPE = 2 and 4) now skip DO_JUMP commands (loops) while following the mission path. (PX4-Autopilot#26993: fix(navigator): goToNextPositionItem skip loops when required)
