I have updated on my Windows Tablet/Laptop and Windows 10 Mobile (Lumia 950). Both running the latest creators production release (Lumia just updated today).
I started receiving notifications as soon as it installed, not confident it will last but time will tell.
I had a sync failure with 3.17 that fixed itself yesterday. Now with the new update sync is failing again. I may try to uninstall and delete the pairing and reconnect everything (on 3.17 that fixed it for about one sync then broke again).
No change log in the Store.
