Changelog

[0.6.0] - 2026-04-30

Added

• SESSION_SYNC_REQUEST / SESSION_SYNC_REPLY (PP:RequestSessionSync, PP:HandleSessionSyncRequest, PP:HandleSessionSyncReply): leader-only, narrow alternative to SYNC_REQUEST / SYNC_FULL. Reply carries the active guild's roster, the active session record, in-flight pendingLoot, and _completedLootKeys. Broadcast-only with a 5 s cooldown so concurrent requesters from the same burst are coalesced into a single broadcast. SESSION_SYNC_REPLY ships at BULK priority.
• PP:_ensureSessionRecord(guildKey, sessionID, sessionData): installs a minimal session shell when the local record is missing. Used by HandleSessionCreate, HandleLootPost, HandleLootAward, and the new HandleSessionSyncReply.
• LOOT_POST and LOOT_AWARD payloads now carry a minimal session field ({ name, startTime, leader, guildKey }) so receivers who missed SESSION_CREATE can install a record before showing the response popup or recording an award.

Changed

• All internal RequestSync callers swapped to RequestSessionSync (_ScheduleJoinSync, CompletePendingSessionEnd, OnGuildRosterUpdate, OnPlayerEnteringWorld ungrouped path, HandleSessionCreate fresh-roster trigger, and the LOOT_AWARD version-gap recovery in HandleLootAward). The Settings-tab "Request Sync" button still calls RequestSync / SYNC_FULL as the manual escape hatch for a multi-guild dump.
• HandleLootPost gates the response popup behind _ensureSessionRecord. If the receiver missed SESSION_CREATE and the sender did not carry the session field (old client), the post is dropped and a RequestSessionSync is issued; the leader's reply repopulates pendingLoot.
• HandleLootAward invokes _ensureSessionRecord before RecordItemAward. If installation fails, the score change still applies (roster is independent) but the item is not recorded into a phantom session and a RequestSessionSync is issued.

Removed

• ComputeRosterHash and the PP.ComputeRosterHash export. Roster broadcasts ship the full table on every mutation alongside a strictly-monotonic rosterVersion; equal versions imply equal state.
• hash field on ROSTER_UPDATE and SYNC_REQUEST payloads, rosterHash on LOOT_AWARD and GROUP_SCORE.
• _groupScoreHashes cache and the GROUP_SCORE_ACK round-trip (PP.MSG.GROUP_SCORE_ACK, HandleGroupScoreAck). GROUP_SCORE itself stays — only the per-receiver acknowledgement dies. Wire-breaking: clients on older versions still send GROUP_SCORE_ACK, which new clients silently ignore (no dispatch branch).
• Hash-mismatch recovery branches in HandleRosterUpdate and HandleLootAward. Version-gap detection on LOOT_AWARD is retained and now triggers RequestSessionSync.
• "Roster hash:" line from the /pp Settings status panel.

[0.5.1] - 2026-04-28

Added

• Roster snapshots: end-of-session standings frozen per session. Captured locally by every client on PP.Session:End() (skipped for RESET and SYNC_DELETE); shipped inline on SESSION_CLOSE; backfilled on demand via SNAPSHOT_REQUEST / SNAPSHOT_REPLY (BULK priority). sessionSnapshots table added to guilds[guildKey] schema (auto-backfilled by EnsureData). Arbitration by rosterVersion — newest wins.
• New PP.Repo.Roster methods: GetSessionSnapshot, SetSessionSnapshot, BuildRosterSnapshot, GetAllSnapshotVersions.
• Roster snapshot UI: "View Roster Snapshot" button on ended-session detail view; popup window lists frozen standings sorted by score. "Fetch Session Snapshots" button in the Settings tab triggers a group-wide backfill (5 s cooldown).
• LOOT_CLEAR message type: raid leader broadcasts after 60 s of an empty queue. Receivers wipe their loot display and mark the cleared keys as completed so late LOOT_POST messages cannot re-pop them. Idle timer cancels on new posts and on session end/create.
• PP:LocalClearLoot() and /pp loot clear (/pp l clear): wipes pending loot for this client only, no broadcast. Settings tab gains a "Clear My Loot Display" button.
• PARTY_LEADER_CHANGED handler (OnPartyLeaderChanged): hands off the idle-clear timer when leadership transfers.
• Bounded post-join sync retry (_ScheduleJoinSync): up to 3 attempts (3 s, then 9 s, then 15 s) issuing RequestSync; stops once an active session is adopted, the group is left, or no other PP users are present.
• _completedLootKeys runtime table tracks cleared/awarded/cancelled loot keys to suppress late re-posts.

Changed

• Reliable broadcast simplified: per-member whisper retry loop removed. BroadcastCritical now broadcasts once and relies on the ACK hash check to detect divergence — any mismatch schedules a single SendFullSync. _criticalAckSnapshots entries auto-expire after 30 s.
• Message priority dropped from ALERT to NORMAL for loot/session/sync traffic. LOOT_STATE_QUERY, RAID_SETTINGS, and the new SNAPSHOT_* messages remain at BULK.
• LOOT_AWARD payload now carries rosterVersion and rosterHash — receivers update score, advance rosterVersion, and verify the hash from a single message. Separate ROSTER_DELTA on award removed; gap detection requests a full sync.
• ROSTER_DELTA requires sequential version application; any gap (incoming != local + 1) triggers RequestSync.
• LOOT_CANCEL payload now includes guildKey so the ACK hash compares against the same roster on every client.
• BroadcastSessionCreate payload reduced to {name, startTime} — recipients reconstruct the session shell locally.
• HandleSyncRequest responds using the responder's own active guild key (no longer filters by requester guild match) so a joining player with a stale _activeGuildKey is not ignored by every officer.
• SendFullSync(guildKey, target): targeted whispers bypass the broadcast cooldown.
• HandleSyncFull only auto-creates foreign guild records when the message is a whispered reply received within 15 s of our own RequestSync and the sender is currently in our group.
• HandleSyncFull ends a local stale session when the sender authoritatively cleared theirs at a newer activeSessionVersion.
• PP.Session:RecordItemAward accepts an optional guildKey parameter; HandleLootAward passes the payload's guildKey so receivers with a stale _activeGuildKey still write into the correct session.
• Default session names: when multiple sessions are created on the same day they auto-increment as Session YYYY-MM-DD #2, #3, …
• HandleSessionCreate rebuilds the session shell from the trimmed payload and routes via PP.Repo.Roster:SetActiveSessionID.

Fixed

• Whisper-only SYNC_FULL and SNAPSHOT_REPLY no longer accepted from non-group senders or outside their request trust window — prevents arbitrary guild-key injection and snapshot-poisoning via unsolicited whispers.
• LOOT_CLEAR validated as raid-leader-only; pending keys are marked completed before the local wipe so a delayed LOOT_POST cannot re-introduce a cleared item.
• Snapshot pop-up window released on SESSION_DELETE so it cannot reference a deleted session.

[0.5.0] - 2026-04-22

Added

• Reliable broadcast (BroadcastCritical): initial RAID/PARTY broadcast + per-member whisper retry for critical messages (LOOT_POST, LOOT_AWARD, LOOT_CANCEL, SESSION_CREATE, SESSION_CLOSE, SESSION_DELETE, ROSTER_DELTA, GROUP_SCORE). Retries 3× with 4s delay before giving up.
• ACK message type: receivers echo back a roster hash so the sender can detect divergence and trigger a delta or full sync.
• Roster delta sync (ROSTER_DELTA / BroadcastRosterDelta): sends only changed/removed entries instead of the full roster on every update.
• Group score sync (GROUP_SCORE / GROUP_SCORE_ACK): dedicated round-trip for boss-kill point awards with per-member acknowledgement.
• Message priority system: LOOT, SESSION, and SYNC messages sent at ALERT priority; bulk sync at BULK priority.
• Handshake on group join: automatically requests a version check from all online members.
• Full sync throttle: additional full syncs are suppressed within a 10-second cooldown.
• ComputeRosterHash: deterministic roster hash used to detect drift without exchanging the full payload.
• /pp debug command: toggles sync debug output to chat (replaces /pp bagdebug).
• /pp minimap command: toggles minimap icon visibility.
• Minimap visibility checkbox in the Settings tab.
• ShowMinimapIcon() / HideMinimapIcon() methods with persistence across reloads.
• Default session names auto-increment within a day (Session YYYY-MM-DD, Session YYYY-MM-DD #2, …).
• _ppUsers runtime table: tracks which group members have the addon loaded.

Changed

• All slash-command handlers consolidated into Commands/Commands.lua (was split across DevCommands.lua, RosterCommands.lua, SessionCommands.lua).
• SendFullSync no longer accepts a target parameter — full syncs always broadcast to the group.
• Loot key format changed to itemLink:timestamp:index for stable chronological sort across reloads.
• Loot master window width increased to 850.
• Tooltip overlay frames reused instead of recreated on each draw.

Fixed

• Loot master window sort order: entries now sort chronologically by timestamp, with index as tiebreaker within the same second.
• Whisper reflection attack vector: the addon no longer echoes whisper-delivered messages back to the sender.
• Potential duplicate ACK keys replaced with a time-based GUID.

[0.4.0] - 2026-03-22

Added

• Minimap icon with LibDBIcon-1.0: left-click toggles main window, right-click opens loot master window
• Pending loot bars UI: visual progress bars for active loot postings

Fixed

• Leader change stale raid: session now correctly reactivates on rejoin after leader swap
• Sync gating to prevent unintentional guild entry creation

[0.3.2] - 2026-03-21

Changed

• Clarified GetData vs EnsureData API in PP.Repo.Roster: EnsureData auto-creates the guild entry if missing; GetData returns nil for absent entries

Fixed

• Added nil-guards after GetData() calls in Sync.lua, LootService, SessionService, and main.lua to prevent crashes when guild data is absent

• Refactored business logic into Service layer (PP.Session, PP.Roster, PP.Loot)
• Session teardown consolidated into single PP.Session:End() path
• Pending trades now persist across UI reloads

Fixed

• Spurious client-side session ends on disconnect/reconnect (disconnect recovery window)
• LEADER_LEFT session end now deferred 5 seconds to survive leader promotion windows
• CheckActiveRaid moved to fire after world load so IsInGroup() is accurate on reload
• Auto-pass epic+ setting now included in full sync payload (resilient to race with loot rolls)
• Cancel and Award loot actions now gated by CanPostLoot() permission check
