 * [ENHANCEMENT] Experimental WAL: Ingester WAL records now have type header and the custom WAL records have been replaced by Prometheus TSDB's WAL records. Old records will not be supported from 1.3 onwards. Note: once this is deployed, you cannot downgrade without data loss. #2436
 * [ENHANCEMENT] Redis Cache: Added `idle_timeout`, `wait_on_pool_exhaustion` and `max_conn_lifetime` options to redis cache configuration. #2550
 * [ENHANCEMENT] WAL: the experimental tag has been removed on the WAL in ingesters.
-* [BUGFIX] Ruler: Ensure temporary rule files with special characters are properly mapped and cleaned up. #2506
 * [ENHANCEMENT] Use newer AWS API for paginated queries - removes 'Deprecated' message from logfiles. #2452
+* [ENHANCEMENT] Experimental TSDB: added the following metrics to the ingester: #2580
+  * `cortex_ingester_tsdb_appender_add_duration_seconds`
+  * `cortex_ingester_tsdb_appender_commit_duration_seconds`
+* [BUGFIX] Ruler: Ensure temporary rule files with special characters are properly mapped and cleaned up. #2506
 * [BUGFIX] Fixes #2411, Ensure requests are properly routed to the prometheus api embedded in the query if `-server.path-prefix` is set. #2372
 * [BUGFIX] Experimental TSDB: fixed chunk data corruption when querying back series using the experimental blocks storage. #2400
 * [BUGFIX] Cassandra Storage: Fix endpoint TLS host verification. #2109
