 <!-- This changes the project to: -->
 
+- Fix `SERVE_ROBOTS_TXT` setting file after the double slash fix broke it.
+
 ## 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)).

 - Allow multiple consecutive slashes in a row in application paths ([#754](https://github.com/TecharoHQ/anubis/issues/754)).
 - Add option to set `targetSNI` to special keyword 'auto' to indicate that it should be automatically set to the request Host name ([424](https://github.com/TecharoHQ/anubis/issues/424)).
 - The Preact challenge has been removed from the default configuration. It will be deprecated in the future.
+- An open redirect when in subrequest mode has been fixed.

+### 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.
