Sauce Connect has received two significant updates to improve its performance and functionality. The new version of Sauce Connect tunnels enables faster startup times, with a notable reduction in the time it takes for connections to establish. Additionally, the updated tunnels now support the WebSocket protocol, allowing for more efficient communication between clients and servers in tested applications. As part of this update, Sauce Labs is gradually migrating all Sauce Connect tunnels to the new architecture, with the goal of providing improved performance and reliability over time.
