Interesting. I checked the website and there's no information on it. My Edge 130 is still on SW 3.70 and the Windows 10 application doesn't show an update available. You must be part of the earlier rollout.
I'm surprised, cause usually updates for Asian countries get later than for US & Europe. Or maybe there was a critical mistake in SW 3.60 and Garmin hurried to fix it (just like an Apple inc.) . Anyway the new update is expected soon.
