 ### Added
-
+- [#7763](https://github.com/thanos-io/thanos/pull/7763) Ruler: use native histograms for client latency metrics.
 - [#7609](https://github.com/thanos-io/thanos/pull/7609) API: Add limit param to metadata APIs (series, label names, label values).
 - [#7429](https://github.com/thanos-io/thanos/pull/7429): Reloader: introduce `TolerateEnvVarExpansionErrors` to allow suppressing errors when expanding environment variables in the configuration file. When set, this will ensure that the reloader won't consider the operation to fail when an unset environment variable is encountered. Note that all unset environment variables are left as is, whereas all set environment variables are expanded as usual.
 - [#7560](https://github.com/thanos-io/thanos/pull/7560) Query: Added the possibility of filtering rules by rule_name, rule_group or file to HTTP api.
