[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

     [ https://issues.oasis-open.org/browse/MQTT-592?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Davide Lenzarini updated MQTT-592:
----------------------------------
    Proposal: Duplicate the PUBLISH packet definition and have distinct versions for QoS -1 & 0 and QoS 1 & 2. The former will have no mention of PacketId  (was: Duplicate the CONNECT packet definition and have distinct versions for QoS -1 & 0 and QoS 1 & 2. The former will have no mention of PacketId)

> The presense of PacketID in the CONNECT is not required when publishing QoS -1 or QoS 0 messages. Omitting it as an optimisation in these cases would save 2 bytes per flight.
