Microsoft has pressed the button. Silently and secretly. I’ve been waiting two days, but until today Microsoft has not published a change log. I have received isolated messages after the update of Next Generation Sync Client (NGSC). After the update and the first start, the NGSC has crashed. For me the NGSC has automatically raised on three different devices to version 17.3.6798.0207 and I have no problems with Windows 8.1 and Windows 10.

For those, who do not know: You, or your admin do not have to do anything. The NGSC will be automated updated, if Microsoft press the Button. If Microsoft has done some changes on OneDrive for Business, OneDrive or SharePoint Online AND they also need changes on the client, the can initiate the update. No Admin required. But You may update your machine  to another version, doing it manually

For those people Microsoft has published a change log, but I have written above, there is no change log to this version, only for the old versions.*)

But I do have my own change log over all versions

OneDrive for Business | Next Generation Sync Client (all Versions)

and here you will have also the possibility to download **) the different versions. (I do not own a Mac, therefore this time no MAC Download)

Somehow the worm is in Microsoft. First no security updates, then a new NGSC version, but no publication. Let’s hope it gets better.

 

*)[Update 02/18/17]

Microsoft has published  a new entry in the change log. There are so many versions between 6743 and 6798, but the only statement from Microsoft is: “Fixed the top issues related to sync reliability and application stability.”

**)There are 3 locations, where you are able to download the NGSC Client from Microsoft and install it manually, but that’s not the latest version

Location	Version
New OneDrive sync client release notes	17.3.6743.1212
Enable users to sync SharePoint Files with the new OneDrive sync client	17.3.6743.1212
OneDrive for Windows	17.3.6743.1212

[Update 02/22/17]

Several people told me, that you now do not have to insert the TeamSiteSyncPrevie Key in the registry to sync data from Team sites, with the version 17.3.6798.0207 this is obsolete.
