 # Changelog
 
+## 2025-03-26 - 2.6.7 - fix(setup.sh)
+Clarify net-snmp dependency installation message in setup.sh
+
+- Updated echo statement to indicate installation of net-snmp along with 2 subdependencies
+- Improves clarity on dependency installation during setup
+
+## 2025-03-26 - 2.6.6 - fix(setup.sh)
+Improve setup script to detect and execute npm-cli.js directly using the Node.js binary
+
+- Replace use of the npm binary with direct execution of npm-cli.js
+- Add fallback logic to locate npm-cli.js when not found at the expected path
+- Simplify cleanup by removing unnecessary PATH modifications
+
+## 2025-03-26 - 2.6.5 - fix(daemon, setup)
+Improve shutdown command detection and fallback logic; update setup script to use absolute Node/npm paths
+
+- Use execFileAsync to execute shutdown commands reliably
+- Add multiple fallback alternatives for shutdown and emergency shutdown handling
+- Update setup.sh to log the Node and NPM versions using absolute paths without modifying PATH
+
+## 2025-03-26 - 2.6.4 - fix(setup)
+Improve installation process in setup script by cleaning up package files and ensuring a minimal net-snmp dependency installation.
+
+- Remove existing package-lock.json along with node_modules to prevent stale artifacts.
+- Back up the original package.json before modifying it.
+- Create a minimal package.json with only the net-snmp dependency based on the backed-up version.
+- Use a clean install to guarantee that only net-snmp is installed.
+- Restore the original package.json if the installation fails.
+
+## 2025-03-26 - 2.6.3 - fix(setup)
+Update setup script to install only net-snmp dependency and create a minimal package-lock.json for better dependency control.
+
+- Removed full production dependency install in favor of installing only net-snmp@3.20.0
+- Added verification step to confirm net-snmp installation
+- Generate a minimal package-lock.json if one does not exist
+
+## 2025-03-26 - 2.6.2 - fix(setup/readme)
+Improve force update instructions and dependency installation process in setup.sh and readme.md
+
+- Clarify force update commands with explicit paths in readme.md
+- Remove existing node_modules before installing dependencies in setup.sh
+- Switch from 'npm ci --only=production' to 'npm install --omit=dev' with updated error instructions
+
+## 2025-03-26 - 2.6.1 - fix(setup)
+Update setup.sh to temporarily add vendor Node.js binary to PATH for dependency installation, log Node and npm versions, and restore the original PATH afterwards.
+
+- Temporarily prepend vendor Node.js binary directory to PATH to ensure proper npm execution.
+- Log Node.js and npm versions for debugging purposes.
+- Restore the original PATH after installing dependencies.
+
 ## 2025-03-26 - 2.6.0 - feat(setup)
 Add --force update flag to setup script and update installation instructions
