 # Changelog
 
 ## master / unreleased
+* [CHANGE] Ingester: Remove EnableNativeHistograms config flag and instead gate keep through new per-tenant limit at ingestion. #6718
 * [CHANGE] StoreGateway/Alertmanager: Add default 5s connection timeout on client. #6603
 * [FEATURE] Query Frontend: Add dynamic interval size for query splitting. This is enabled by configuring experimental flags `querier.max-shards-per-query` and/or `querier.max-fetched-data-duration-per-query`. The split interval size is dynamically increased to maintain a number of shards and total duration fetched below the configured values. #6458
 * [FEATURE] Querier/Ruler: Add `query_partial_data` and `rules_partial_data` limits to allow queries/rules to be evaluated with data from a single zone, if other zones are not available. #6526
