- [CERT management was improved](https://codeberg.org/forgejo/forgejo/pulls/3724) when [`ENABLE_ACME=true`](https://forgejo.org/docs/v7.0/admin/config-cheat-sheet/#server-server)
  -   Draft support for draft-03 of [ACME Renewal Information (ARI)](https://datatracker.ietf.org/doc/draft-ietf-acme-ari/) which assists with deciding when to renew certificates. This augments CertMagic's already-advanced logic using cert lifetime and OCSP/revocation status.
  -   New [`ZeroSSLIssuer`](https://pkg.go.dev/github.com/caddyserver/certmagic@v0.21.0#ZeroSSLIssuer) uses the [ZeroSSL API](https://zerossl.com/documentation/api/) to get certificates. ZeroSSL also has an ACME endpoint, which can still be accessed using the existing ACMEIssuer, as always. Their proprietary API is paid, but has extra features like IP certificates, better reliability, and support.
  -   DNS challenges should be smoother in some cases as we've improved propagation checking.
  -   In the odd case your ACME account disappears from the ACME server, CertMagic will automatically retry with a new account. (This happens in some test/dev environments.)
  -   ACME accounts are identified only by their public keys, but CertMagic maps accounts by CA+email for practical/storage reasons. So now you can "pin" an account key to use by specifying your email and the account public key in your config, which is useful if you need to absolutely be sure to use a specific account (like if you get rate limit exemptions from a CA).
