 * [CHANGE] Querier: the CLI flag `-querier.minimize-ingester-requests` has been moved from "experimental" to "advanced". #7638
 * [CHANGE] Ingester: `/ingester/flush` endpoint is now only allowed to execute only while the ingester is in `Running` state. The 503 status code is returned if the endpoint is called while the ingester is not in `Running` state. #7486
 * [CHANGE] Distributor: Include label name in `err-mimir-label-value-too-long` error message: #7740
+* [FEATURE] Continuous-test: now runable as a module with `mimir -target=continuous-test`. #7747
 * [FEATURE] Store-gateway: Allow specific tenants to be enabled or disabled via `-store-gateway.enabled-tenants` or `-store-gateway.disabled-tenants` CLI flags or their corresponding YAML settings. #7653
 * [FEATURE] New `-<prefix>.s3.bucket-lookup-type` flag configures lookup style type, used to access bucket in s3 compatible providers. #7684
 * [ENHANCEMENT] Store-gateway: merge series from different blocks concurrently. #7456
