+## [2001.2.1]
+
+### Fixes
+* Fixed "Show waypoints in world" client config setting being ignored for waypoint icons
+  * It was only working to suppress beacons when set to false, now it suppresses icons too
+* Fixed NPE when checking for fake players which had a null name or UUID in their GameProfile
+* Client memory fix; eliminated some unnecessary region data loading when players change chunk settings (claiming, forceloading)
+
 ## [2001.2.0]
