Adds retain support for publishing messages #169

Closed Fapiko closed 1 year ago

Fapiko commented 4 years ago

This adds retains support to published messages. It should be backwards compatible with existing clients as it defaults to false if not supplied.

Solves #20 and #161

Is there any example how to call this function in the code? unfortunately I have no idea how can I use it.

Thank you

When will this be merged? Seems all tests have passed and it is backward compatible, so what is the holdup? The feature is sorely needed!

Please merge!

I made an up-to-date version of this which overloads the publish and publishPacket functions rather than using optional arguments:
