This is stated to fix the errors introduced by wind smoothing processing in 3.51 in breaking out the headwind and crosswind components. It affected perhaps some reports, A/P nav and FMC component reports and A/P control, etc. It would affect flight planning programs that take winds in to effect for headings and groundspeed/fuel management calculations such as FSBuild 2.x which reads directly from Active Sky 2004.5 and up.
