On October 5, 2023, Microsoft announced the general availability of the new Teams 2.1 client. Based on a new architecture and promising better performance and lower system resource usage, Teams 2.1 is available for Windows and macOS desktops and browsers. The signs are good as the client has been in public preview since March, but we'll only really know how successful the client is after several months of use.
