v2.8.0

Caddy 2.8 is here! With hundreds of improvements, Caddy is more scalable and capable than ever before. Featuring ACME Renewal Information (ARI) support, HTTP/3 to proxy backends, and so much more than we can list in a sentence, we are pleased to bring you one of the biggest Caddy updates yet. Documentation on our website will be updated in the coming days.

We've implemented a ton of improvements, fixes, and awesome new features based on your feedback. While some of them aren't particularly visible changes, they allow Caddy to scale better and be more reliable in demanding deployments. Many of the changes are quality-of-life improvements we hope you'll appreciate. Then there's improvements to ACMEz, CertMagic, and other dependencies which make Caddy better that may not show up in this list.

There was a lot of code that had been documented as deprecated in place for a long time, so this version introduces a few more breaking changes than usual; please review the notes below.

Thank you to our sponsors and everyone in the community who contributed -- over 40 of you made your first contribution for this release. We couldn't have done it without your help. In particular, we'd like to recognize sponsors Stripe, Framer, and ZeroSSL for their positive influence which have greatly enhanced the project. Caddy 2.8 is already being used in our sponsors' large-scale, multi-region production deployments.

Want to join those ranks? Sponsor the Caddy project and benefit from development priority, dedicated private support, and much more.

As with any server upgrades, please be sure to test and validate your configurations in a staging or test environment before deploying to production. Thank you and have a great day!

⚠️ Breaking changes:

• ZeroSSL (#6229) (this is one overall change, but requires some explanation):
  • Up to now, Caddy used both Let's Encrypt and ZeroSSL by default to get certificates without any configuration. In 2.8, this is changing slightly. Due to upcoming changes to ZeroSSL accounting policies, ZeroSSL now requires your email address to be able to access their free ACME endpoint.
  • As such, Caddy will only implicitly add the ZeroSSL issuer to your config if you provide an email address in your Caddyfile using the email global option. (We have already recommended this for years.) If you already do this, you don't have to make any changes and you'll still get Let's Encrypt and ZeroSSL automatically as defaults.
  • If you use JSON to configure certificate automation policies, you will need to ensure you use the acme issuer with your email filled out, and the ca field set to ZeroSSL's ACME server URL.
  • The zerossl issuer module is no longer ACME-capable and is now exclusively for the ZeroSSL API. An API key from your ZeroSSL account is required. (The ZeroSSL ACME server can still be used with the acme module pointed to ZeroSSL's ACME server. You can provide your account email and/or EAB as well.) If you were using the ZeroSSL issuer with an API key, it will now start using ZeroSSL's API, which was probably the expected behavior anyways. The API has several advantages over the ACME endpoint, but may require payment:
    • Faster response times
    • IP certificates
    • Management tools in your ZeroSSL account dashboard
