+* [CHANGE] Alertmanager: Don't expose cluster information to tenants via the `/alertmanager/api/v1/status` API endpoint when operating with clustering enabled. #3903
 * [CHANGE] Ingester: don't update internal "last updated" timestamp of TSDB if tenant only sends invalid samples. This affects how "idle" time is computed. #3727
 * [CHANGE] Require explicit flag `-<prefix>.tls-enabled` to enable TLS in GRPC clients. Previously it was enough to specify a TLS flag to enable TLS validation. #3156
-* [CHANGE] Query-frontend: removed `-querier.split-queries-by-day` (deprecated in Cortex 0.4.0). You should use `-querier.split-queries-by-interval` instead. #3813
+* [CHANGE] Query-frontend: removed `-querier.split-queries-by-day` (deprecated in Cortex 0.4.0). Please use `-querier.split-queries-by-interval` instead. #3813
 * [CHANGE] Store-gateway: the chunks pool controlled by `-blocks-storage.bucket-store.max-chunk-pool-bytes` is now shared across all tenants. #3830
 * [CHANGE] Ingester: return error code 400 instead of 429 when per-user/per-tenant series/metadata limits are reached. #3833
 * [CHANGE] Compactor: add `reason` label to `cortex_compactor_blocks_marked_for_deletion_total` metric. Source blocks marked for deletion by compactor are labelled as `compaction`, while blocks passing the retention period are labelled as `retention`. #3879
 * [CHANGE] Alertmanager: the `DELETE /api/v1/alerts` is now idempotent. No error is returned if the alertmanager config doesn't exist. #3888
 * [FEATURE] Experimental Ruler Storage: Add a separate set of configuration options to configure the ruler storage backend under the `-ruler-storage.` flag prefix. All blocks storage bucket clients and the config service are currently supported. Clients using this implementation will only be enabled if the existing `-ruler.storage` flags are left unset. #3805 #3864

-* [FEATURE] Adds support to S3 server-side encryption using KMS. The S3 server-side encryption config can be overridden on a per-tenant basis for the blocks storage, ruler and alertmanager. Deprecated `-<prefix>.s3.sse-encryption`, you should use the following CLI flags that have been added. #3651 #3810 #3811 #3870 #3886 #3906

 * [FEATURE] Querier: Enable `@ <timestamp>` modifier in PromQL using the new `-querier.at-modifier-enabled` flag. #3744
-* [FEATURE] Overrides Exporter: Add `overrides-exporter` module for exposing per-tenant resource limit overrides as metrics. It is not included in `all` target, and must be explicitly enabled. #3785
+* [FEATURE] Overrides Exporter: Add `overrides-exporter` module for exposing per-tenant resource limit overrides as metrics. It is not included in `all` target (single-binary mode), and must be explicitly enabled. #3785
 * [FEATURE] Experimental thanosconvert: introduce an experimental tool `thanosconvert` to migrate Thanos block metadata to Cortex metadata. #3770
 * [FEATURE] Alertmanager: It now shards the `/api/v1/alerts` API using the ring when sharding is enabled. #3671
   * Added `-alertmanager.max-recv-msg-size` (defaults to 16M) to limit the size of HTTP request body handled by the alertmanager.

 Note the blocks storage compactor runs a migration task at startup in this version, which can take many minutes and use a lot of RAM.
 [Turn this off after first run](https://cortexmetrics.io/docs/blocks-storage/production-tips/#ensure-deletion-marks-migration-is-disabled-after-first-run).
