Always use the latest stable versions of GitHub Actions components in CI/CD workflows to avoid deprecated features, security vulnerabilities, and compatibility issues. This includes: 1. Use the latest version of common actions: ```yaml # Use this - uses: actions/checkout@v4 # Instead of these older versions - uses: actions/checkout@v3 - uses: actions/checkout@v2 ``` 2. Reference the canonical branch name in external actions: ```yaml # Use this - uses: actionshub/chef-install@main # Instead of - uses: actionshub/chef-install@master ``` 3. Keep runner images updated to currently supported versions: ```yaml # Use these runs-on: macos-11 # or newer runs-on: windows-2022 # instead of windows-2016 # Replace deprecated runners like # runs-on: macos-10.15 # runs-on: windows-2016 ``` Regular updates reduce security risks, ensure compatibility with GitHub's evolving infrastructure, and prevent build failures when older components are deprecated or removed. Create a recurring task to audit and update actions versions across your workflows.
