 ## 0.8.x
+### 0.8.3: Fix – OptimaLab35 Not Closing After Update
+- Fixed an issue where **OptimaLab35** would not close properly when updating, resulting in an unresponsive instance and multiple running processes.
+
 ### 0.8.2: Patch for New PyPiUpdater Version
 - Updated to support **PyPiUpdater 0.4.0**.
 - Now stores version information locally, preventing an "unknown" state on the first updater launch.
