 - fixed Firefox tab crashes when running with `ProtectHostImages=y` enabled [#4394](https://github.com/sandboxie-plus/Sandboxie/issues/4394)
   - Only default installation locations are considered; Firefox-based browsers installed outside of these locations may still crash.
   - To prevent this, manually add `DontCopy=<CustomInstallPath>` for custom installation paths to your configuration
+- fixed BSOD "SYSTEM_SERVICE_EXCEPTION (3b)" when opening a DLL from AlertFolder using x64dbg [#4421](https://github.com/sandboxie-plus/Sandboxie/issues/4421)
+- fixed BSoD "CRITICAL_PROCESS_DIED" when terminate all sandboxed programs [#1316](https://github.com/sandboxie-plus/Sandboxie/issues/1316)
+  - Note: we now terminate boxed processes individually instead of terminating using the job object, unless "TerminateJobObject=y" is set
