How to release Fluentd

Create PR

• Add entry CHANGELOG.md
• Bump version lib/fluent/version.rb
• Update Supported Versions in SECURITY.md when major or minor version (x or y in x.y.z) is updated
• Commit with message "vX.Y.Z"
• Example: v1.12.4

Rebase and merge PR

• Do not merge commit (Want to refer changelog entries in specific tag - git log v1.12.4)
  • Rebase and merge
  • Use it from pull down menu

Release gem files

Note: You need to use Ruby v3.1 or later to generage gems (since v1.14.4).

Note: You don't need a Windows environment to build the gems for MinGW since it just changes the dependencies.
