# Versioning and compatibility

Since Sidecar SDK v3.0.0, the TLS connection method has been deprecated in favor of non-TLS connections. You should use Sidecar image version 2.494.0 or later. Note that TLS self-signed certificates expire on January 26, 2026, so upgrading is strongly recommended to avoid service interruptions.
