Mimir's feed is mostly bot-authored Helm bumps; the real release is 3.2, and it is query-engine work.

◆Current state
Four of the six visible entries are automated weekly Helm chart releases opened by a bot, which inflates the apparent cadence without carrying product change. The substance sits in the 3.2 release candidate: 693 pull requests from 61 authors, dominated by Mimir Query Engine optimizations — scalar common subexpression elimination, subquery splitting and caching from instant queries, native histogram support in extended range selectors, histogram_quantiles, and a rename of the experimental duration helpers to min_of and max_of. Operational additions include named per-tenant cost attribution trackers, a tenant-fair compute worker pool in the ingester, memberlist compression selection and Kafka producer compression control.
◆Where it's heading
Two threads dominate. MQE is being ground into the default query path piece by piece — each release moves another optimization or PromQL surface behind a flag, and the flags accumulate rather than flip. The second is multi-tenant fairness and chargeback: cost attribution trackers, a shared tenant-fair worker pool and compression controls are all about making one tenant's queries not everyone else's problem, which is what a hosted operator needs before raising density.
◆Prediction
Expect the experimental MQE flags introduced here to move toward default-on in a subsequent release, and cost attribution to grow reporting surfaces now that multiple named trackers per tenant exist.

    Mimir 3.2 RC: query engine optimizations and cost attribution

    The one real release in the window, gathering 693 pull requests. It continues the incremental march of the Mimir Query Engine — subexpression elimination, subquery splitting and caching, native histogram operators — and adds the multi-tenant fairness pieces (named cost attribution trackers, a tenant-fair ingester worker pool) that make dense hosting viable. Substantial in volume, but the direction is the same one previous releases set.

    Helm chart 6.1.0 pins Mimir 3.1.2

    The stable chart release wiring Mimir 3.1.x into mimir-distributed 6.1.0. Packaging that follows the engine release rather than a change to Mimir itself.
