-To align with Zoom’s [recent announcement](https://blog.zoom.us/wordpress/2020/04/22/zoom-hits-milestone-on-90-day-security-plan-releases-zoom-5-0/) pertaining to our security initiative, Zoom Client SDKs have added **AES 256-bit GCM encryption** support, which provides more protection for meeting data and greater resistance to tampering. **The system-wide account enablement of AES 256-bit GCM encryption will take place on June 01, 2020.** You are **strongly recommended** to start the required upgrade to this latest version 4.6.21666.0428 at your earliest convenience. Please note that any Client SDK versions below 4.6.21666.0428 will **no longer be operational** from June 01.
 
-> If you would like to test the latest SDK with AES 256-bit GCM encryption meeting before 05/30, you may:
-> 1. Download the latest version of Zoom client: https://zoom.us/download
-> 2. Visit https://zoom.us/testgcm and launch a GCM enabled meeting with your Zoom client, you will see a Green Shield icon that indicates the GCM encryption is enabled
-> 3. Use SDK to join this meeting
