🚀 Feature Request

Relevant Package [REQUIRED]

MQTT Client

Description [REQUIRED]

Current github.com/eclipse/paho.mqtt.golang module doesn't support MQTT 5

Describe the solution you'd like

The https://github.com/eclipse/paho.golang does and should also support MQTT 3.1

Describe alternatives you've considered

Have you considered any alternative solutions or workarounds?

@cloudxxx8 , @jumpingliu, I looked at https://github.com/eclipse/paho.golang and it is not plug and play with the 3.x Client. This will require more refactoring of the MQTT implementation than we want to do in the Napa release. Suggest this be moved to the ice box.

[cloudxxx8]

@lenny-intel thanks for looking into it. I agree with you, moving to icebox.

waiting for the library to be mature

[cloudxxx8]

it's currently v0.12, and it contains some breaking changes against v0.11
we want to wait for v1.0, a stable release

Left this in Icebox, as https://github.com/eclipse/paho.golang is only 0.22 and the effort is really huge.

is this mature enough for v5?

This library hasn't been updated for 2 years, and the latest version is 0.5.0
