 ## What's New
 
+### v0.4.1 - 2026-02-16
+- **Added**
+  - **Guardrails for dangerous commands**: Loz now includes built-in safety guardrails that automatically block potentially dangerous shell commands before execution. The following commands are blocked:
+    - `rm -rf /` and its bypass variants (`rm -rf/*`, `rm -rf /.`)
+    - `shutdown` and `reboot` commands
+    - Fork bomb: `:(){ :|:& };:`
+    - Filesystem formatting: `mkfs`
+    - Direct disk operations: `dd if=`
+  - This feature provides an additional layer of protection to prevent accidental system damage, complementing the existing confirmation prompts.
