Automatic client update can be enabled by installing the "Advanced Configuration Editor" extension, then going to Admin -> Advanced -> Web Configuration -> Settings -> "Automatically Update Agent Version"

Also having problems with many duplicate access clients. When computer are reimaged and the client is reinstalled, it creates a duplicate with the same name instead of merging or replacing the old one.

It's possible to get email notifications for new versions by subscribing to the Control Output Stream from your profile here in the UserEcho system.

Also, I found a great script for automatically updating connectwise control server Auto-Update ConnectWiseControl : ConnectWiseControl (reddit.com)

Thanks for the info. Would the ability to subscribe to stable release notifications be better as a separate feature request since this one is closed?  Perhaps a better feature request would be for improving the update process for on-premise installations? (We use on-premise connectwise control) I can open a new feature request with ideas for that function if it makes sense to do so.
