-> **Notice:** I am actively working on a major performance refactor. Until I publish a stable release that I am satisfied with, please use the repository version instead of the release asset.
->
+> **Notice:** This is a maintenance release, not the completed performance refactor. The performance refactor is still in progress on the `phase2-lua50-sweep` branch. This release (v1.6.4) contains bug fixes and improvements over v1.6.3 and should be more stable, but the full performance work will land in a future release. If you are currently on v1.6.3, this release is a recommended upgrade.
+
 > Current refactor focus: reducing QuestieLearner pin redraws during heavy kill activity, adding live Advanced performance controls for QuestieLearner and QuestieComms, adding Arrow throttles for low-end systems, and suppressing non-fatal error spam outside Questie debug modes. These changes are being staged on feature branches first and still need in-game validation before they become the next stable release.
