What is Grafana Mimir?

Mimir's feed is weekly chart bot noise; the 3.2 RC is where the breaking changes hide.

Almost every entry in this window is an identical bot-generated Helm chart release — byte-for-byte the same body across seven tags. The one substantive release is the 3.2.0 RC, whose notes run past the feed's truncation point: continued Mimir Query Engine optimisation, native histogram support in more operators, per-tenant cost attribution trackers, and a tenant-fair compute worker pool on the ingester. Buried in its changelog are changes operators must act on — the embedded per-tenant Alertmanager web UI is gone, credential-bearing headers are now rejected at startup, and querier/store-gateway traffic requires coming from 3.1.

What is OpenMetadata?

OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.

OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.

5.0

Mimir's feed is weekly chart bot noise; the 3.2 RC is where the breaking changes hide.

◆ Current state

Almost every entry in this window is an identical bot-generated Helm chart release — byte-for-byte the same body across seven tags. The one substantive release is the 3.2.0 RC, whose notes run past the feed's truncation point: continued Mimir Query Engine optimisation, native histogram support in more operators, per-tenant cost attribution trackers, and a tenant-fair compute worker pool on the ingester. Buried in its changelog are changes operators must act on — the embedded per-tenant Alertmanager web UI is gone, credential-bearing headers are now rejected at startup, and querier/store-gateway traffic requires coming from 3.1.

◆ Where it's heading

Mimir is deepening the query path rather than widening the product: most of 3.2 is MQE work, subquery spin-off, caching and elimination passes, largely behind experimental flags. The operational surface is growing in parallel — Kafka producer controls, mimirtool and kafkatool subcommands, SigV4 for shared API clients. The chart is versioned and released independently on a weekly bot cadence, which is why the feed reads as empty even in an active month.

◆ Prediction

The experimental MQE flags that landed in 3.2 are the ones to watch for promotion to default in 3.3, particularly subquery spin-off and scalar common subexpression elimination. Whether a 3.2.0 final follows this RC is not visible in the feed — only the RC has been published here.

5.0

OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.

◆ Current state

OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.

◆ Where it's heading

The 2.0 launch is being paid for in connector repairs, and the cadence of roughly weekly maintenance suggests a large installed surface. Protecting user-managed metadata from bot ingestion, and multi-pod fixes in 2.0.6, point at production deployments rather than trials. The 2.1 candidate is the first sign of attention moving forward, but the published notes do not show its contents.

◆ Prediction

Expect a 2.1 release soon, with its real scope clearer once proper notes appear. 2.0.x maintenance should continue alongside it.
