If you're upgrading an existing application, it's a great idea to have good test coverage before going in. You should also first upgrade to Rails 7.2 in case you haven't and make sure your application still runs as expected before attempting an update to Rails 8.0. A list of things to watch out for when upgrading is available in the Upgrading Ruby on Rails guide.

See the full list of contributors to Rails for the many people who spent many hours making Rails, the stable and robust framework it is. Kudos to all of them.

Please contribute if you see any typos or factual errors. To get started, you can read our documentation contributions section.

You may also find incomplete content or stuff that is not up to date. Please do add any missing documentation for main. Make sure to check Edge Guides first to verify if the issues are already fixed or not on the main branch. Check the Ruby on Rails Guides Guidelines for style and conventions.

If for whatever reason you spot something to fix but cannot patch it yourself, please open an issue.
