+### Potentially breaking changes
+
+#### Multiple checks at once has and-like semantics instead of or-like semantics
+
+Anubis lets you stack multiple checks at once with blocks like this:
+
+```yaml
+name: allow-prometheus
+action: ALLOW
+user_agent_regex: ^prometheus-probe$
+remote_addresses:
+  - 192.168.2.0/24
+```
+
+Previously, this only returned ALLOW if _any one_ of the conditions matched. This behaviour has changed to only return ALLOW if _all_ of the conditions match. I expect this to have some issues with user configs, however this fix is grave enough that it's worth the risk of breaking configs. If this bites you, please let me know so we can make an escape hatch.
+
+### Better error messages
+
+In order to make it easier for legitimate clients to debug issues with their browser configuration and Anubis, Anubis will emit internal error detail in base 64 so that administrators can chase down issues. Future versions of this may also include a variant that encrypts the error detail messages.

+
+If you run BotStopper in a multi-tenant environment where each tenant needs its own branding, BotStopper supports the ability to use request header values to direct asset reads to different folders under your `OVERLAY_FOLDER`. One of the most common ways to do this is based on the HTTP Host of the request. For example, if you set `ASSET_LOOKUP_HEADER=Host` in BotStopper's environment:

 As a workaround, you should configure your web server to parse an alternative source (such as `CF-Connecting-IP`), or pre-process the incoming `X-Forwarded-For` with your web server to ensure it only contains the real client IP address, then pass it to Anubis as `X-Forwarded-For`.
 
+If you do not control the web server upstream of Anubis, the `custom-real-ip-header` command line flag accepts a header value that Anubis will read the real client IP address from. Anubis will set the `X-Real-IP` header to the IP address found in the custom header.
+
 The `X-Real-IP` header will be automatically inferred from `X-Forwarded-For` if not set, setting it explicitly is not necessary as long as `X-Forwarded-For` contains only the real client IP. However setting it explicitly can eliminate spoofed values if your web server doesn't set this.

+| `COOKIE_SECURE`                | `true`                  | If set to `true`, enables the [Secure flag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/Cookies#block_access_to_your_cookies), meaning that the cookies will only be transmitted over HTTPS. If Anubis is used in an unsecure context (plain HTTP), this will be need to be set to false                                                                                                                                                                                                                                          |
-| `JWT_RESTRICTION_HEADER`       | `X-Real-IP`             | If set, the JWT is only valid if the current value of this header matches the value when the JWT was created. You can use it e.g. to restrict a JWT to the source IP of the user using `X-Real-IP`.                                                                                                                                                                                                                                                                                                     |

Allowed: `None`, `Lax`, `Strict`, `Default`. `None` permits cross-site use but modern browsers require it to be **Secure**—so if `COOKIE_SECURE=false` or you serve over plain HTTP, use `Lax` (recommended) or `Strict` or the cookie will be rejected. `Default` uses the Go runtime’s `SameSiteDefaultMode`. `None` will be downgraded to `Lax` automatically if cookie is set NOT to be secure. |

This should be exactly 64 characters long. **Required when using persistent storage backends** (like bbolt) to ensure challenges survive service restarts. When running multiple instances on the same base domain, the key must be the same across all instances.
