- [ENHANCEMENT] Add validation to ensure `enterprise.adminToken.secret` is set when provisioner is enabled. [#18803](https://github.com/grafana/loki/pull/18803)
- [BUGFIX] Websocket related proxy_set_header to locations back to resolve high CPU usage. [#18800](https://github.com/grafana/loki/pull/18800). **CAUTION**: Any customized proxy_set_header configuration are moved from `gateway.nginxConfig.httpSnippet` to `gateway.nginxConfig.locationSnippet`. Users that using different authentication methods (e.g. `mTLS`) in the gateway should check their configuration and update it accordingly.
