+## What's New in Version 6.2.1 (January 10, 2026)
+
+### 🎯 Debuff Timer Protection System (libdebuff.lua)
+
+- ✅ **Spell Rank Tracking** - Tracks spell rank for all your DoTs/debuffs
+  - Uses `lastCastRanks` table to preserve rank information across multiple event sources
+  - Fixes race condition where SuperWoW UNIT_CASTEVENT fired before QueueFunction processed pending data
+- ✅ **Lower Rank Protection** - Lower rank spells cannot overwrite higher rank timers
+  - Example: If Moonfire Rank 10 is active, casting Rank 5 will be blocked
+- ✅ **Other Player Protection** - Other players' casts cannot overwrite your debuff timers
+  - Your DoTs are tracked separately from other players' DoTs
+  - Multiple players can have their own Moonfire/Corruption on the same target
+- ✅ **Shared Debuff Whitelist** - Debuffs that are shared by all players update correctly:
+  - Warrior: Sunder Armor, Demoralizing Shout, Thunder Clap
+  - Rogue: Expose Armor
+  - Druid: Faerie Fire, Faerie Fire (Feral)
+  - Hunter: Hunter's Mark
+  - Warlock: Curse of Weakness/Recklessness/Elements/Shadow/Tongues/Exhaustion
+  - Priest: Shadow Weaving
+  - Mage: Winter's Chill
+  - Paladin: All Judgements
