 #### Loki
 
 ##### Fixes
 
-* [11606](https://github.com/grafana/loki/pull/11606) **dannykopping** Fixed regression adding newlines to HTTP error response bodies which may break client integrations.
 * [11601](https://github.com/grafana/loki/pull/11601) **dannykopping** Ruler: Fixed a panic that can be caused by concurrent read-write access of tenant configs when there are a large amount of rules.
+* [11612](https://github.com/grafana/loki/pull/11612) **dannykopping** Ruler: catering for another data race in tenant config.
 * [11657](https://github.com/grafana/loki/pull/11657) **ashwanthgoli** Log results cache: compose empty response based on the request being served to avoid returning incorrect limit or direction.
 * [11654](https://github.com/grafana/loki/pull/11654) **dannykopping** Cache: atomically check background cache size limit correctly. 
 * [11587](https://github.com/grafana/loki/pull/11587) **trevorwhitney** Fix semantics of label parsing logic of metrics and logs queries. Both only parse the first label if multiple extractions into the same label are requested.
