MQTT 5 is the most recent version of the MQTT specification. It includes many new features that are very useful for implementing specific IoT use cases. For example, Vehicle to Anything (V2X), Connected Cars, Smart Toll Booth, etc.

In this webinar, Florian Raschbichler, Head of Support at HiveMQ, covered some of the main features of MQTT 5, such as:

• Topic Aliases
• Shared Subscriptions
• Request / Response Pattern
• User Properties
• Session and Message Expiry
• Payload Type Descriptors
• Enhanced Authentication

Florian also illustrated some of the real-life IoT use cases that can be solved using these MQTT 5 features.
