Video conferencing service Zoom is urging users to update to the latest version – 5.0 – as it plans to enable GCM (Galois/Counter Mode) encryption, and after May 30, users on older versions will be required to upgrade before being allowed to join meetings.

The company claimed that GCM encryption will offer "increased protection" for meetings.
