+## v1.23.0: Lyse Hext
+
+- Add default tencent cloud DENY rule.
+- Added `(data)/meta/default-config.yaml` for importing the entire default configuration at once.
 - Add `-custom-real-ip-header` flag to get the original request IP from a different header than `x-real-ip`.
 - Add `contentLength` variable to bot expressions.
 - Add `COOKIE_SAME_SITE_MODE` to force anubis cookies SameSite value, and downgrade automatically from `None` to `Lax` if cookie is insecure.
 - Fix lock convoy problem in decaymap ([#1103](https://github.com/TecharoHQ/anubis/issues/1103)).
 - Fix lock convoy problem in bbolt by implementing the actor pattern ([#1103](https://github.com/TecharoHQ/anubis/issues/1103)).
+- Remove bbolt actorify implementation due to causing production issues.
 - Document missing environment variables in installation guide: `SLOG_LEVEL`, `COOKIE_PREFIX`, `FORCED_LANGUAGE`, and `TARGET_DISABLE_KEEPALIVE` ([#1086](https://github.com/TecharoHQ/anubis/pull/1086)).
 - Add validation warning when persistent storage is used without setting signing keys.
 - Fixed `robots2policy` to properly group consecutive user agents into `any:` instead of only processing the last one ([#925](https://github.com/TecharoHQ/anubis/pull/925)).
+- Make the `fast` algorithm prefer purejs when running in an insecure context.
 - Add the [`s3api` storage backend](./admin/policies.mdx#s3api) to allow Anubis to use S3 API compatible object storage as its storage backend.
 - Fix a "stutter" in the cookie name prefix so the auth cookie is named `techaro.lol-anubis-auth` instead of `techaro.lol-anubis-auth-auth`.
 - Make `cmd/containerbuild` support commas for separating elements of the `--docker-tags` argument as well as newlines.

+### 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.

 ## Configuring allowed redirect domains
 
-By default, Anubis will limit redirects to be on the same HTTP Host that Anubis is running on (EG: requests to yoursite.com cannot redirect outside of yoursite.com). If you need to set more than one domain, fill the `REDIRECT_DOMAINS` environment variable with a comma-separated list of domain names that Anubis should allow redirects to.
+By default, Anubis may redirect to any domain which could cause security issues in the unlikely case that an attacker passes a challenge for your browser and then tricks you into clicking a link to your domain.
+One can restrict the domains that Anubis can redirect to when passing a challenge by setting up `REDIRECT_DOMAINS` environment variable.
+If you need to set more than one domain, fill the environment variable with a comma-separated list of domain names.
+There is also glob matching support. You can pass `*.bugs.techaro.lol` to allow redirecting to anything ending with `.bugs.techaro.lol`. There is a limit of 4 wildcards.

-These domains are _an exact string match_, they do not support wildcard matches.
