When will this happen: 
Hotpatching is generally available.  
 
How this will affect your organization: 
Hotpatch updates save time by installing in the background without interruption or restarts. They drive business continuity by ensuring that users remain secure and productive, without disruption.  
 
What you need to do to prepare: 
  • Check if your organization is ready for hotpatch updates.  
  • Confirm devices at your organization meet prerequisites for hotpatching. 
  • Ensure devices are on the latest baseline release version to qualify for hotpatch updates.
