 ## [Unreleased]
 
 ### Added
-- Added UNFLEE behavior (to stop fleeing from a player)
-- Added support for non path aware entities to FLEE (i.e. Ghast)
-- Added new LLM tests for UNFLEE
+- New **whitelist / blacklist** Minecraft **commands**, to show and hide chat bubbles based on entity type
+- New **S2C packets** to send whitelist / blacklist changes on login and after commands are executed
+- Added **UNFLEE behavior** (to stop fleeing from a player)
+- Added support for **non path aware** entities to **FLEE** (i.e. Ghast)
+- Added **new LLM tests** for UNFLEE
 
 ### Changed
+- Chat Bubble **rendering** & interacting is now dependent on **whitelist / blacklist** config
+- Improved client **render performance** (only query nearby entities every 3rd call)
 - Fixed a **crash with FLEE** when non-path aware entities (i.e. Ghast) attempted to flee.
-- Fixed certain behaviors from colliding with others (i.e. mutual exclusive ones)
+- Updated ATTACK **CHARGE_TIME** to be a little **faster** (when non-native attacks are used)
+- Extended **click sounds** to 12 blocks away (from 8)
+- Fixed certain **behaviors** from colliding with others (i.e. **mutual exclusive** ones)
 - Updated README.md with new video thumbnail, and simplified text, added spoiler to install instructions
-- Fixed CurseForge deploy script to be much faster, and correctly lookup valid Type and Version IDs
+- Large **refactor** of Minecraft **commands** (and how --config args are parsed)
+- Fixed **CurseForge deploy script** to be much faster, and correctly lookup valid Type and Version IDs
