The `mimir-distributed` Helm chart is the best way to install Mimir on Kubernetes. + +The highlights that follow include the top features, enhancements, and bug fixes in this release. For a comprehensive list of changes, see the [Helm chart changelog](https://github.com/grafana/mimir/tree/main/operations/helm/charts/mimir-distributed/CHANGELOG.md). + +## Important changes + +- The ingester is configured with `GOMAXPROCS` to help with overhead from the Go scheduler, observed on hosts with a large number of CPU cores. +- The GEM query-frontend logs the query author's access policy name and token name in the query statistics logs. This provides more visibility as which token is running a potentially expensive query. +- Dashboards are updated to allow switching between classic and native histograms in the queries that support it. + +## Features and enhancements + +Notable enhancements are as follows: + +- The dashboard configuration maps support setting a namespace. +- The `topologySpreadConstraints` configuration of all components is updated to better match what is allowed in Kubernetes. +- Metamonitoring supports AWS Signature Version 4 (sigv4) authentication for remote write. +- Metamonitoring is updated to allow its Grafana Agent pods to set image pull secrets, node selectors, tolerances, topology spread constraints, and resource requests and limits. +- The continous-test is updated to allow setting separate read and write URLs. +- The continous-test can be enabled in GEM.
