 * [FEATURE] Ruler: Add new `-ruler.query-stats-enabled` which when enabled will report the `cortex_ruler_query_seconds_total` as a per-user metric that tracks the sum of the wall time of executing queries in the ruler in seconds. #4317
 * [FEATURE] Query Frontend: Add `cortex_query_fetched_series_total` and `cortex_query_fetched_chunks_bytes_total` per-user counters to expose the number of series and bytes fetched as part of queries. These metrics can be enabled with the `-frontend.query-stats-enabled` flag (or its respective YAML config option `query_stats_enabled`). #4343
+* [FEATURE] AlertManager: Add support for SNS Receiver. #4382
 * [CHANGE] Update Go version to 1.16.6. #4362
 * [CHANGE] Querier / ruler: Change `-querier.max-fetched-chunks-per-query` configuration to limit to maximum number of chunks that can be fetched in a single query. The number of chunks fetched by ingesters AND long-term storare combined should not exceed the value configured on `-querier.max-fetched-chunks-per-query`. #4260
 * [CHANGE] Memberlist: the `memberlist_kv_store_value_bytes` has been removed due to values no longer being stored in-memory as encoded bytes. #4345
