 # Upgrading Efs-utils Versions
 
 ### Upgrading efs-utils from v1 to v2
-Efs-utils v2.0.0 replaces stunnel, which provides TLS encryptions for mounts, with efs-proxy an AWS built component built. Efs-proxy is the primary the foundation for all new feature support for EFS. To receive the performance benefits of efs-proxy, you need to re-mount any existing mounts. Note: Efs-proxy is not compatible with OCSP or Mac clients. In these cases, efs-utils will automatically revert back to using stunnel. If you build efs-utils v2.0.0 from source Rust and Cargo are required for versions 1.70+.
