Hanami | Hanami 2.3: Racked and Ready

We are excited to bring Rack 3 support to Hanami! We now support both versions 2 and 3, so you can use whichever version of Rack suits your situation. We encourage you to upgrade Rack when you can, and we’re happy that Hanami can help you on this path. When you upgrade to Rack 3, check out the Rack 3 upgrade guide. Hanami already handles the essential changes for you, but you may need to update your app code if you’re working with Rack request/response details.
