Got my update too yesterday. Funny thing is my watch now has Android 6.01 with the May security update but my Moto X Pure phone is still at Android 6.0 with the Feb security update. Maybe phones will be updated soon too?
I'm on android wear version 1.4.0.2576000, android 6.01. I did check for updates and it says it is up to date. It does not show me security patch level, is that new to android wear 1.5? My google play services is same version as above screen shot. I'm a bit worried about an upgrade, my notifications work well, I don't want some bug screwing it up.
I got updated last night. I will have to try theater mode before charging tonight. I have no need for the display to be on all night. How does one do a screenshot on the watch anyway?
Another bug fix: when you charge with the screen off, the backlight turns off completely now, making the face pitch black. It used to remain on, ever so dimly.
