Mythic+ Party Shuffle

v0.16.5 (2026-06-20)

Full Changelog Previous Releases

• feat(comm): coalesced resync broadcast + cross-faction resync fixes
  Answer late-joiner ROSTER_REQ by the medium it ARRIVED on instead of a
  per-requester unicast whisper:
  • GUILD/CHANNEL arrivals are coalesced into ONE broadcast per ~2s window,
    cutting host outbound from O(requesters x pages) to ~O(pages) on a join
    storm (e.g. 40 guildmates at raid start). WHISPER arrivals keep the
    unicast answer.
  • Route by arrival medium, not _transportTo: a same-realm non-guild joiner
    bootstraps over whisper and only upgrades to the channel after this
    answer, so a channel broadcast would never reach it.
  • Trust GUILD arrivals (_guildSeen): a freshly-joined cross-faction
    guildmate not yet in the cached guild set is still answered over the
    GUILD broadcast leg, not a community-dependent whisper. Refresh the local
    guild roster on JoinEvent.
  • Spoke resync resilience: quick early retries {5,10,15}s and a bounded
    keep-alive that no longer gives up on first silence, so a cross-faction
    spoke whose first whisper was dropped during community warm-up converges
    without a relog. The host per-src answer coalesce absorbs the retries.
    266 lua tests pass; check-lua clean. Archives change
    coalesce-resync-broadcast (comm-protocol spec updated). Resets DEV_BUILD
    to 0 for the v0.16.5 release.
