 * [CHANGE] Querier: Use `-blocks-storage.tsdb.retention-period` instead of `-querier.query-ingesters-within` for calculating the lookback period for shuffle sharded ingesters. Setting `-querier.query-ingesters-within=0` no longer disables shuffle sharding on the read path. #4287

 * [ENHANCEMENT] Store-gateway: reduce memory usage in some LabelValues calls. #4789
 * [ENHANCEMENT] Store-gateway: add a `stage` label to the metric `cortex_bucket_store_series_data_touched`. This label now applies to `data_type="chunks"` and `data_type="series"`. The `stage` label has 2 values: `processed` - the number of series that parsed - and `returned` - the number of series selected from the processed bytes to satisfy the query. #4797 #4830
