 # Changelog
 
+## 2025-03-25 - 1.9.0 - feat(cli)
+Add update command to CLI to update NUPST from repository and refresh the systemd service
+
+- Integrate 'update' subcommand in CLI command parser
+- Update documentation and help output to include new command
+- Implement update process that fetches changes from git, runs install.sh/setup.sh, and refreshes systemd service if installed
+
+## 2025-03-25 - 1.8.2 - fix(cli)
+Refactor logs command to use child_process spawn for real-time log tailing
+
+- Replaced execSync call with spawn to properly follow logs
+- Forward SIGINT to the spawned process for graceful termination
+- Await the child process exit to ensure clean shutdown of the CLI log command
+
+## 2025-03-25 - 1.8.1 - fix(systemd)
+Update ExecStart in systemd service template to use /opt/nupst/bin/nupst for daemon startup
+
+- Changed ExecStart from '/usr/bin/nupst daemon-start' to '/opt/nupst/bin/nupst daemon-start' in the systemd service file
+- Ensures the service uses the correct binary installation path
+
 ## 2025-03-25 - 1.8.0 - feat(core)
 Enhance SNMP module and interactive CLI setup for UPS shutdown
