+# Releasing pflag
+
+This document describes how to create a new pflag release.
+
+## Method 1: GitHub UI (recommended by maintainers)
+
+1. Go to the [releases page](https://github.com/spf13/pflag/releases)
+2. Click **"Draft a new release"**
+3. Click **"Generate release notes"** — this shows the merged PRs since the last tag, which helps determine the next version (minor vs patch)
+4. Choose the tag version (e.g., `v1.0.8`) — the tag will be created when the release is published
+5. Review the generated notes, then publish
+
+This method has the advantage that the tag and release are published atomically, and the PR list helps pick the right version number before tagging.
+
+## Method 2: GitHub CLI
+
+```bash
+git checkout master
+git pull origin master
+
+# Tag and push
+git tag v1.0.8
+git push origin v1.0.8
+
+# Create release with auto-generated notes
+gh release create v1.0.8 --generate-notes
+```
+
+## Notes
+
+pflag follows [Semantic Versioning](https://semver.org/). Check the [releases page](https://github.com/spf13/pflag/releases) for the latest tag.
