     * `-ingest-storage.read-consistency`: configures the default read consistency.
     * `-ingest-storage.migration.distributor-send-to-ingesters-enabled`: enabled tee-ing writes to classic ingesters and Kafka, used during a live migration to the new ingest storage architecture.
     * `-ingester.partition-ring.*`: configures partitions ring backend.
+* [FEATURE] Querier: added support for `limitk()` and `limit_ratio()` experimental PromQL functions. Experimental functions are disabled by default, but can be enabled setting `-querier.promql-experimental-functions-enabled=true` in the query-frontend and querier. #8632
 * [CHANGE] Distributor: Incoming OTLP requests were previously size-limited by using limit from `-distributor.max-recv-msg-size` option. We have added option `-distributor.max-otlp-request-size` for limiting OTLP requests, with default value of 100 MiB. #8574
 * [ENHANCEMENT] Compactor: Add `cortex_compactor_compaction_job_duration_seconds` and `cortex_compactor_compaction_job_blocks` histogram metrics to track duration of individual compaction jobs and number of blocks per job. #8371
 * [ENHANCEMENT] Rules: Added per namespace max rules per rule group limit. The maximum number of rules per rule groups for all namespaces continues to be configured by `-ruler.max-rules-per-rule-group`, but now, this can be superseded by the new `-ruler.max-rules-per-rule-group-by-namespace` option on a per namespace basis. This new limit can be overridden using the overrides mechanism to be applied per-tenant. #8378
