#MQTT V5.0 Committee Specification 02 approved & published

OASIS is pleased to announce that Committee Specification 02 of MQTT Version 5.0 from the OASIS Message Queuing Telemetry Transport (MQTT) TC [1] has been approved as an OASIS Committee Specification.

MQTT is a Client Server publish/subscribe messaging transport protocol. It is light weight, open, simple, and designed to be easy to implement. These characteristics make it ideal for use in many situations, including constrained environments such as for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts where a small code footprint is required and/or network bandwidth is at a premium.

The protocol runs over TCP/IP, or over other network protocols that provide ordered, lossless, bi-directional connections.

The changes from CS01 were non-material. A red-lined PDF highlighting the changes is also included in this package [2].

This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.
