 # Changelog
 
+### 3.0.0
+- Add support for DNS-01 challenges.
+  - Check out the list of all currently [supported authenticators](./certbot_authenticators.md).
+  - This also means it is now possible to request wildcard certificates!
+  - PR by [XaF][32].
+- Make it possible to define which authenticator to use on a certificate basis.
+  - Like with [ECDSA/RSA](./advanced_usage.md#multi-certificate-setup), you can
+    [add the authenicator's name](./certbot_authenticators.md#using-a-dns-01-authenticator-for-specific-certificates-only)
+    in the `cert_name` to override the default.
+  - PR by [XaF][32].
+- Make it possible to use same `cert_name` across multiple config files.
+  - The scripts will remember all domain names associated with the cert name.
+  - This means you can now use as many config files as you want and have them all point to a single certificate.
+- Add [BATS][34].
+  - A lot unit tests for the Bash functions we use in the [`util.sh`](../src/scripts/util.sh) file.
+  - Also add it as a [GitHub action](../.github/workflows/unit_tests.yml).
+  - A huge thank you to [XaF][33] for providing the foundation for this.
+- Add ability to override found `server_name`.
+  - By adding a comment on the `server_name` line the script will now use [that instead](./advanced_usage.md#override-server_name).
+  - This enables you to easily group domains under a common wildcard certificate ([example config](../examples/example_server_overrides.conf)).
+- Any server name beginning with '`~`' will be ignored.
+  - This character means that the server name is a regex, and we cannot use it when requesting certificates.
+- Use [ECDSA](./good_to_know.md#ecdsa-and-rsa-certificates) certificates by default.
+  - You now have to explicitly set `USE_ECDSA=0` to disable this.
+- We aren't actually introducing any breaking changes, but such a large change deserves a major release.
+- Update documentation.
+- Update examples.
+
+
