Colossus receive an unannounced patch (unknown whether bug or intentional buff)

Nakajin: "So, it has gone under the radar (at least mine), but Colossus received a buff where the Extended thermal range now upgrades the range to +10 rather than +9.

Apparently there's some confusion as if it's a bug or an intended feature, but in any case, quite a meaningful buff to protoss for now."
