+# RabbitMQ .NET Client release process
+
+## Ensure builds are green:
+
+* [GitHub Actions](https://github.com/rabbitmq/rabbitmq-dotnet-client/actions)
+
+
+## Update API documentation
+
+Note: `main` (`6.x` and later) only

+Run `tools/generate-changelog.sh` with the previous tag and the new tag:
+
+```
+tools/generate-changelog.sh v7.X.Y v7.X.(Y+1)
+```
+
+This inserts a new section into `CHANGELOG.md` after the `# Changelog` header.
+The release date is set to `UNRELEASED-DATE` as a placeholder. Review the
+output with `git diff CHANGELOG.md` and edit as needed before committing.
+
+
+## Create and push release tag
+
+Note: `alpha` releases are versioned by default via the MinVer package. The version is based off of the most recent tag.
+
+RC release:
+
+```
+git tag -a -s -u B1B82CC0CF84BA70147EBD05D99DE30E43EAE440 -m 'rabbitmq-dotnet-client v7.X.Y-rc.1' 'v7.X.Y-rc.1'
