As a manager of an ArcGIS deployment, you play a crucial role in keeping your installed software up-to-date with the latest patches. Depending on the size of your GIS or organization, this task may be challenging, but it's essential for the smooth operation of your system.
The easiest way to stay informed is through the Esri Support app - support.esri.com/en-us/app. In this app, you can use the Patches tab to see the latest releases.
If you want to be notified of new patches, be sure to enable notifications from the Esri Support app on your mobile device so you stay updated with the information for your ArcGIS deployment.
