- * DEVELOPER PREVIEW DISCLAIMER
- *
- * MQTT5 support is currently in **developer preview**.  We encourage feedback at all times, but feedback during the
- * preview window is especially valuable in shaping the final product.  During the preview period we may make
- * backwards-incompatible changes to the public API, but in general, this is something we will try our best to avoid.
