5.1 changed my life when I downloaded it on my series 3. So many new features.

On my series 4 as well. Night and day difference. If I look closely into the bright Apple logo, I can almost make out the time.
 
did they release 5.1 after all? my s3 shows that 512MB is taken up on the watch by a software update, and if i go to the software update page in my watch app, the software update to 5.1 offer appears (and stays - previously it would flash the upgrade screen monentariy and then just report up-to-date on 5.0.1)
