I'm a bit confused by the versioning scheme. My model 3 (euro spec) is on 2019.5.25 - is this more recent than .15 or older? No sentry mode - really hoping this starts landing on this side of the sea soon :-(
As far as we can tell 2019.5.25 was a Europe only version. There has been some discussion on here on whether the camera recording for Sentry Mode complies with GDPR in Europe. It's very possible that GDPR compliance is delaying or preventing Sentry Mode (at least the camera recording portion) from coming to Europe.
