Auto Update of Unity Hub
The Unity Hub features two channels for receiving updates. The default channel is Production, which will alert you to stable updates of the Hub.
The other channel is the Beta channel, which will update you with the newest features before they are officially released. You can test these new features and will be alerted to all updates of the Hub.
When there is an update to the Hub, a banner will appear at the top:
To continue to use the outdated version of the Hub, select Dismiss. To update to the newest version in your channel, select Restart. This will restart the Hub application so that the updates can take effect.
To access the webpage where you can submit feedback regarding the Hub to the team, select Send feedback.
For more details on updates to the Hub, see the Release Notes.
