Zoom© Forces Upgrade For Users of Older Versions of Software

5.0 is Here! 
On May 30th, 2020, Zoom will enable GCM encryption across the entire Zoom platform, providing increased protection for meeting data.

After May 30, 2020, all Zoom clients on older versions will receive a forced upgrade when trying to join meetings as GCM encryption will be fully enabled across the Zoom platform; you cannot join meetings after May 30 without an updated client. Please begin updating all your clients to Zoom 5.0 now.
