5 | | -### Grafana Mimir |
6 | | - |
7 | | -* [ENHANCEMENT] Stagger head compaction intervals across zones to prevent compactions from aligning simultaneously, which could otherwise cause strong consistency queries to fail when experimental ingest storage is enabled. #12090 |
8 | | -* [ENHANCEMENT] Compactor: Add `-compactor.update-blocks-concurrency` flag to control concurrency for updating block metadata during bucket index updates, separate from deletion marker concurrency. #12117 |
9 | | -* [ENHANCEMENT] Query-frontend: Allow users to set the `query-frontend.extra-propagated-headers` flag to specify the extra headers allowed to pass through to the rest of the query path. #12174 |
10 | | -* [BUGFIX] Ingester: Fix issue where ingesters can exit read-only mode during idle compactions, resulting in write errors. #12128 |
11 | | -* [BUGFIX] otlp: Reverts #11889 which has a pooled memory re-use bug. #12266 |

15 | | -### Grafana Mimir |
16 | | - |
17 | | -* [FEATURE] Distributor: Add experimental `-distributor.otel-native-delta-ingestion` option to allow primitive delta metrics ingestion via the OTLP endpoint. #11631 |
18 | | -* [FEATURE] MQE: Add support for experimental `sort_by_label` and `sort_by_label_desc` PromQL functions. #11930 |
19 | | -* [FEATURE] Ingester/Block-builder: Handle the created timestamp field for remote-write requests. #11977 |
20 | | -* [FEATURE] Cost attribution: Labels specified in the limit configuration may specify an output label in order to override emitted label names. #12035 |
21 | | -* [ENHANCEMENT] Ingester: Display user grace interval in the tenant list obtained through the `/ingester/tenants` endpoint. #11961 |
22 | | -* [ENHANCEMENT] `kafkatool`: add `consumer-group delete-offset` command as a way to delete the committed offset for a consumer group. #11988 |
23 | | -* [ENHANCEMENT] Block-builder-scheduler: Detect gaps in scheduled and completed jobs. #11867 |
24 | | -* [ENHANCEMENT] Distributor: Experimental support for Prometheus Remote-Write 2.0 protocol has been updated. Created timestamps are now supported. This feature includes some limitations. If samples in a write request aren't ordered by time, the created timestamp might be dropped. Additionally, per-series metadata is automatically merged on the metric family level. Ingestion might fail if the client sends ProtoBuf fields out-of-order. The label `version` is added to the metric `cortex_distributor_requests_in_total` with a value of either `1.0` or `2.0`, depending on the detected remote-write protocol. #11977 |
25 | | -* [ENHANCEMENT] Query-frontend: Added labels query optimizer that automatically removes redundant `__name__!=""` matchers from label names and label values queries, improving query performance. You can enable the optimizer per-tenant with the `labels_query_optimizer_enabled` runtime configuration flag. #12054 #12066 #12076 #12080 |
26 | | -* [ENHANCEMENT] Query-frontend: Standardise non-regex patterns in query blocking upon loading of config. #12102 |
27 | | -* [ENHANCEMENT] Ruler: Propagate GCS object mutation rate limit for rule group uploads. #12086 |
28 | | -* [BUGFIX] Distributor: Validate the RW2 symbols field and reject invalid requests that don't have an empty string as the first symbol. #11953 |
29 | | -* [BUGFIX] Distributor: Check `max_inflight_push_requests_bytes` before decompressing incoming requests. #11967 |
30 | | -* [BUGFIX] Query-frontend: Allow limit parameter to be 0 in label queries to explicitly request unlimited results. #12054 |
31 | | -* [BUGFIX] Distributor: Fix a possible panic in the OTLP push path while handling a gRPC status error. #12072 |
32 | | -* [BUGFIX] Query-frontend: Evaluate experimental duration expressions before sharding, splitting, and caching. Otherwise, the result is not correct. #12038 |
33 | | -* [BUGFIX] Block-builder-scheduler: Fix bugs in handling of partitions with no commit. #12130 |

183 | 148 | * [BUGFIX] Block-builder-scheduler: Fix data loss bug in job assignment. #11785 |
184 | 149 | * [BUGFIX] Compactor: start tracking `-compactor.max-compaction-time` after the initial compaction planning phase, to avoid rare cases where planning takes longer than `-compactor.max-compaction-time` and so actual compaction never runs for a tenant. #11834 |
| 150 | +* [BUGFIX] Distributor: Validate the RW2 symbols field and reject invalid requests that don't have an empty string as the first symbol. #11953 |
