[mqtt5 0.43.1] - 2026-09-27

Fixed

  • A clean-start reconnect no longer receives a message routed to the session it replaced. A publish routed to a client just before that client reconnected with clean_start=1 could land in the new session's queue after the queue had been cleared, delivering a message for a subscription the new session never made (#150). Each client queue now counts its full clears, and a message routed before the latest one is dropped. A resumed session still receives it.
  • The file backend no longer writes a queued message to disk after it was delivered or cleared. A message delivered or cleared at the same moment it was queued could have its delete reach the storage writer before its write, leaving the file on disk; after a restart it was loaded again and redelivered. Writes are now handed to the storage writer before the entry becomes visible to delivery or clearing.

Added

  • ClientQueue::epoch and ClientQueue::push_in_epoch.
