 * [FEATURE] Query frontend: added new query pruning middleware to enable pruning dead code (eg. expressions that cannot produce any results) and simplifying expressions (eg. expressions that can be evaluated immediately) in queries. #9086
 * [FEATURE] Ruler: added experimental configuration, `-ruler.rule-evaluation-write-enabled`, to disable writing the result of rule evaluation to ingesters. This feature can be used for testing purposes. #9060
 * [FEATURE] Ingester: added experimental configuration `ingester.ignore-ooo-exemplars`. When set to `true` out of order exemplars are no longer reported to the remote write client. #9151
+* [FEATURE] gRPC: Support S2 compression. #9322

+* [FEATURE] Query-frontend: added experimental configuration options `query-frontend.cache-errors` and `query-frontend.results-cache-ttl-for-errors` to allow non-transient responses to be cached. When set to `true` error responses from hitting limits or bad data are cached for a short TTL. #9028
+* [FEATURE] The following alertmanager limit was added: #9402
+  * User grafana config size (`-alertmanager.max-config-size-bytes`)
 * [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rule groups for all namespaces continues to be configured by `-ruler.max-rules-per-rule-group`, but now, this can be superseded by the new `-ruler.max-rules-per-rule-group-by-namespace` option on a per namespace basis.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
 * [ENHANCEMENT] Rules: Added per namespace max rule groups per tenant limit. The maximum number of rule groups per rule tenant for all namespaces continues to be configured by `-ruler.max-rule-groups-per-tenant`, but now, this can be superseded by the new `-ruler.max-rule-groups-per-tenant-by-namespace` option on a per namespace basis. This new limit can be overridden using the overrides mechanism to be applied per-tenant. #8425
