 * [CHANGE] Querier: Mark `querier.iterators` and `querier.batch-iterators` flags as deprecated. Now querier always use batch iterators. #5868
-* [FEATURE] OTLP ingestion experimental. #5813
-* [FEATURE] Ingester: Add per-tenant new metric `cortex_ingester_tsdb_data_replay_duration_seconds`. #5477
+* [CHANGE] Query Frontend: Error response returned by Query Frontend now follows Prometheus API error response format. #5811
+* [FEATURE] Experimental: OTLP ingestion. #5813
 * [FEATURE] Query Frontend/Scheduler: Add query priority support. #5605
-* [FEATURE] Tracing: Add `kuberesolver` to resolve endpoints address with `kubernetes://` prefix as Kubernetes service. #5731
+* [FEATURE] Tracing: Use `kuberesolver` to resolve OTLP endpoints address with `kubernetes://` prefix as Kubernetes service. #5731
 * [FEATURE] Tracing: Add `tracing.otel.round-robin` flag to use `round_robin` gRPC client side LB policy for sending OTLP traces. #5731
 * [FEATURE] Ruler: Add `ruler.concurrent-evals-enabled` flag to enable concurrent evaluation within a single rule group for independent rules. Maximum concurrency can be configured via `ruler.max-concurrent-evals`. #5766
 * [FEATURE] Distributor Queryable: Experimental: Add config `zone_results_quorum_metadata`. When querying ingesters using metadata APIs such as label names and values, only results from quorum number of zones will be included and merged. #5779
 * [FEATURE] Storage Cache Clients: Add config `set_async_circuit_breaker_config` to utilize the circuit breaker pattern for dynamically thresholding asynchronous set operations. Implemented in both memcached and redis cache clients. #5789
 * [FEATURE] Ruler: Add experimental `experimental.ruler.api-deduplicate-rules` flag to remove duplicate rule groups from the Prometheus compatible rules API endpoint. Add experimental `ruler.ring.replication-factor` and `ruler.ring.zone-awareness-enabled` flags to configure rule group replication, but only the first ruler in the replicaset evaluates the rule group, the rest will just hold a copy as backup. Add experimental `experimental.ruler.api-enable-rules-backup` flag to configure rulers to send the rule group backups stored in the replicaset to handle events when a ruler is down during an API request to list rules. #5782
+* [ENHANCEMENT] Ingester: Add per-tenant new metric `cortex_ingester_tsdb_data_replay_duration_seconds`. #5477
 * [ENHANCEMENT] Store Gateway: Added `-store-gateway.enabled-tenants` and `-store-gateway.disabled-tenants` to explicitly enable or disable store-gateway for specific tenants. #5638
+* [ENHANCEMENT] Query Frontend: Write service timing header in response even though there is an error. #5653
 * [ENHANCEMENT] Compactor: Add new compactor metric `cortex_compactor_start_duration_seconds`. #5683
 * [ENHANCEMENT] Index Cache: Multi level cache adds config `max_backfill_items` to cap max items to backfill per async operation. #5686
 * [ENHANCEMENT] Query Frontend: Log number of split queries in `query stats` log. #5703
+* [ENHANCEMENT] Compactor: Skip compaction retry when encountering a permission denied error. #5727
 * [ENHANCEMENT] Logging: Added new options for logging HTTP request headers: `-server.log-request-headers` enables logging HTTP request headers, `-server.log-request-headers-exclude-list` allows users to specify headers which should not be logged. #5744
 * [ENHANCEMENT] Query Frontend/Scheduler: Time check in query priority now considers overall data select time window (including range selectors, modifiers and lookback delta). #5758
 * [ENHANCEMENT] Querier: Added `querier.store-gateway-query-stats-enabled` to enable or disable store gateway query stats log. #5749
-* [ENHANCEMENT] AlertManager: Retrying AlertManager Delete Silence on error #5794
+* [ENHANCEMENT] Querier: Improve labels APIs latency by merging slices using K-way merge and more than 1 core. #5785

 * [ENHANCEMENT] Ingester: Add new ingester metric `cortex_ingester_max_inflight_query_requests`. #5798

 * [ENHANCEMENT] Query: Added additional max query length check at Query Frontend and Ruler. Added `-querier.ignore-max-query-length` flag to disable max query length check at Querier. #5808
 * [ENHANCEMENT] Querier: Add context error check when converting Metrics to SeriesSet for GetSeries on distributorQuerier. #5827
-* [ENHANCEMENT] Ruler: Improve GetRules response time by refactoring mutexes and introducing a temporary rules cache in `ruler/manager.go`. #5805
