 # Changelog
 
+## 2025-03-25 - 1.10.1 - fix(systemd/readme)
+Improve README documentation and fix UPS status retrieval in systemd service
+
+- Updated README features and installation instructions to clarify SNMP version support, UPS models, and configuration
+- Modified default SNMP host to '192.168.1.100' and added 'upsModel' property in configuration examples
+- Enhanced instructions for real-time log viewing and update process in README
+- Fixed systemd.ts to use a test configuration with an appropriate timeout when fetching UPS status
+
+## 2025-03-25 - 1.10.0 - feat(core)
+Add update checking and version logging across startup components
+
+- In daemon.ts, log version info on startup and check for updates in the background using npm registry response
+- In nupst.ts, implement getVersion, checkForUpdates, getUpdateStatus, and compareVersions functions with update notifications
+- Establish bidirectional reference between Nupst and NupstSnmp to support version logging
+- Update systemd service status output to include version information
+
+## 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

 ## Features
 
-- Monitors UPS devices using SNMP
+- Monitors UPS devices using SNMP (v1, v2c, and v3 supported)
 - Automatic shutdown when battery level falls below threshold
 - Automatic shutdown when runtime remaining falls below threshold
+- Supports multiple UPS brands (CyberPower, APC, Eaton, TrippLite, Liebert/Vertiv)
 - Simple systemd service integration
+- Regular status logging for monitoring
+- Real-time log viewing with journalctl
+- Version checking and automatic updates
 - Self-contained - includes its own Node.js runtime

+## Updating NUPST
+
+NUPST checks for updates automatically and will notify you when an update is available. To update to the latest version:
+
+```bash
+sudo nupst update
+```
+
+This will:
+1. Pull the latest changes from the git repository
+2. Run the installation scripts
+3. Refresh the systemd service configuration
+4. Restart the service if it was running
+
+## Security
+
+NUPST was designed with security in mind:
+
+### Minimal Dependencies
+
+- **Zero Runtime NPM Dependencies**: NUPST is built without any external NPM packages to minimize the attack surface and avoid supply chain risks.
+- **Self-contained Node.js**: NUPST ships with its own Node.js binary, isolated from the system's Node.js installation. This ensures:
+  - No dependency on system Node.js versions
+  - Zero external libraries that could become compromised
+  - Consistent, tested environment for execution
+  - Reduced risk of dependency-based attacks
+
+### Implementation Security
+
+- **Privilege Separation**: Only specific commands that require elevated permissions (`enable`, `disable`, `update`) check for root access; all other functionality runs with minimal privileges.
+- **Limited Network Access**: NUPST only communicates with the UPS device over SNMP and contacts npmjs.org only to check for updates.
+- **Secure SNMPv3 Support**: Supports encrypted authentication and privacy for secure communication with the UPS device.
+- **Isolated Execution**: The application runs in its working directory (`/opt/nupst`) or specified installation location, minimizing the impact on the rest of the system.
+
+### Installation Security
+
+- The installation script can be reviewed before execution (`curl -sSL [url] | less`)
+- All setup scripts download only verified versions and check integrity
+- Installation is transparent and places files in standard locations (`/opt/nupst`, `/usr/local/bin`, `/etc/systemd/system`)
+
+### Audit and Review
+
+The codebase is small, focused, and designed to be easily auditable. All code is open source and available for review.
