 **HealBotBlue**
 By Bluewhale.
 
+> **NOTE:** For HealBot to work correctly, the **Selfcast** feature in WoW options needs to be disabled.
+
 Original HealBot, while being a staple healing addon in Wrath and later expansions, was in its infancy during Vanilla WoW. It was a memory and CPU hog that ate up resources, featured a clunky UI, and offered limited functions. To fix all of the above while still using it as a base framework, I refactored the entire codebase. The monolithic code structure was split to follow a more modern approach (MVC design pattern), making it more stable and easily editable. Additionally, the inefficient AURA scanning was replaced with lightweight (Observer Pattern) reactive programming. It now updates only what is necessary when a trigger fires, rather than performing clumsy, continuous scans of a 40-man raid. By doing so, I managed to throttle down CPU and memory usage significantly, placing it on par with modern addons. Additional functionalities are being added over time to provide a holistic, healer-centered raid frame.
 
-
-> **NOTE:** For HealBot to work correctly, the **Selfcast** feature in WoW options needs to be disabled.
+> **Performance First:** The raidframe is not library reliant - unlike popular raidframe replacement addons it doesn't rely at all on external frameworks. While this makes my work a bit harder this allows complete control over garbage collection and CPU use which makes it multiple times more stable and lightweight.

 ### Change Log
 
+**v1.6.1**
+* **Hotfix - pet frames** - With class colours toggled extra frames for player pets were given some classy mint colour.
+* **Hotfi - raidframes in combat** - Modfied how frames behave when player leaves during combat.
 
 **v1.6**
 * **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.
