ChangeLog: DeSync

All notable changes to this project will be documented in this file.

[1.0.9] - 2026-06-24

Added

• Sequence- and session-aware heartbeat acknowledgements with independent per-ping timeouts.
• Heartbeat diagnostics in the minimap tooltip and /desync status.
• Configurable screen-flash pulsing, intensity, and repeated alert cadence.
• Custom on-screen warning text with a dedicated localized-default reset.
• Custom on-screen recovery text; the default recovery alert now reads Re-Synced! Delay: before the measured response delay.
• Independent color customization for on-screen warning prefix and suffix symbols.
• Optional raid-marker icons before and after warning text.
• Automated Lua tests for heartbeat state, encounter transitions, send failures, Auto-Tune completion, alert simulation, formatting, and reset behavior.

Changed

• Routine heartbeats now use self-whispers to avoid party and raid broadcast amplification; Classic encounter fallbacks retain safe group routing where required.
• Network Auto-Tune now accounts for average response time, maximum response time, jitter, and observed loss.
• Disconnect chat warning copy now uses best-effort wording so delayed delivery still makes sense after recovery.
• Retail/Midnight TOC interface updated for patches 12.0.7 and 12.1.0.
• Documentation now states that addon-message health is a connection signal, not proof that every world-action subsystem is synchronized.

Fixed

• Thresholds greater than the ping interval can no longer postpone timeout detection indefinitely.
• Delayed replies can no longer acknowledge a newer ping or corrupt its RTT.
• Initial disconnect alerts and recovery alerts now use correct, independent throttles.
• INSTANCE_CHAT alerts are no longer sent from manually formed instance groups.
• Reset-to-defaults immediately reapplies minimap visibility, warning font, and flash color.
• On-screen warning appearance settings can now be reset together without changing unrelated addon settings.
• Encounter Auto-Tune failure messages, encounter pause lifecycle, timer cleanup, and same-name cross-realm filtering.
• Auto-Tune now exits cleanly if an encounter begins while a diagnostic heartbeat is pending.
• Persistent heartbeat send failures now participate in outage detection instead of leaving stale healthy state.
• /desync test is now a bounded simulation that cannot leave the live connection state desynchronized.
• Encounter pause messages now distinguish Retail communication restrictions from solo self-whisper restrictions.
