 ### Change Log
 
 
+**v1.5.1**
+* **Event Loop Decoupling:** Ripped out redundant synchronous UI redraws that were bypassed by the new MVC architecture. High-frequency events (mana regen, health ticks) now fully rely on the `HealBot_OnUpdate` dirty queue, severely reducing CPU bottlenecks.
+* **Combat UI Optimizations:** Removed unnecessary full spell recalculations when dropping combat, preventing client stutter after every mob kill.
+* **Memory Optimization:** Fixed severe Lua garbage collection spikes during UI reloads by preventing full party layout rebuilds on `PLAYER_TARGET_CHANGED`, and cached dynamic string concatenations directly to unit frames to eliminate memory leakage on high frequency UI refreshes.
+* **Mana Validation Fix:** Removed artificial spell mana gating, fixing an issue where low-mana spells disappeared from tooltips and couldn't be cast. WoW's native mana validation now correctly processes 0-cost buffs (e.g. Clearcasting, Inner Focus) while turning low-mana tooltip spells red.
+* **Self-Buff Tracking:** Fixed a bug where "Self Only" buff tracking incorrectly excluded the player when represented by party or raid frames instead of the standard "player" unit ID.
+* **Settings Persistence Fix:** Changed `SavedVariables` to `SavedVariablesPerCharacter` in TOC so configurations correctly load unique per character instead of account-wide.
+* **CPU Optimization:** Added early exit logic to resource tracking events (Mana, Rage, Energy) to stop background polling on party/raid members when "Show Mana Bars" is toggled off. Also removed excessive triggers (`BAG_UPDATE`, `PET_BAR_SHOWGRID`) and filtered `UNIT_INVENTORY_CHANGED` to only process the player, eliminating massive CPU spikes and unnecessary UI layout rebuilds during looting, item cooldowns, or when other players change gear.
+* **OnUpdate GC Spike Fix:** Rewrote the modifier polling logic inside `HealBot_OnUpdate` to use boolean state tracking instead of dynamic string concatenation, eliminating a major source of garbage collection bloat while hovering over unit frames.
+* **Aura Scanning Optimization:** Refactored Debuff tracking (`HealBot_DebuffWatch`) to use native boolean values (`true`/`false`) instead of string comparisons (`"YES"`/`"NO"`). This improves performance inside the continuous aura scanning loops.
+
 **v1.5**
 * **Macro, Item, and Script Bindings:** Support for binding named macros, inventory items, and inline scripts (e.g. `/target`) directly to mouse clicks in the Spells tab. All of these now natively support implicit `@mouseover` targeting on the unit frame you click, without losing your current target.
 * **Modifier-Aware Tooltips & Resource Costs:** The tooltip dynamically updates to show exactly what action is bound when holding down Shift, Ctrl, or Alt over a frame. Spells also show their required mana cost, turning red if you do not have enough mana to cast them.
 * **Memory Recycling Pool:** Added a local table recycling pool in the data layer to greatly reduce Lua garbage collection (GC) spikes, improving overall client frame rates during intense combat.
-* 
+
 **v1.4.2**
 * **Memory Optimization:** Fixed a significant memory leak where tracking tables were being repeatedly allocated every tick during aura scanning, and replaced `table.foreach` with pairs loops to avoid GC spikes during combat.
