 * [ENHANCEMENT] Distributor: invalid metric name error message gets cleaned up to not include non-ascii strings. #7146
 * [ENHANCEMENT] Store-gateway: add `source`, `level`, and `out_or_order` to `cortex_bucket_store_series_blocks_queried` metric that indicates the number of blocks that were queried from store gateways by block metadata. #7112 #7262 #7267
 * [ENHANCEMENT] Compactor: After updating bucket-index, compactor now also computes estimated number of compaction jobs based on current bucket-index, and reports the result in `cortex_bucket_index_estimated_compaction_jobs` metric. If computation of jobs fails, `cortex_bucket_index_estimated_compaction_jobs_errors_total` is updated instead. #7299
+* [ENHANCEMENT] Mimir: Integrate profiling into tracing instrumentation. #7363
 * [BUGFIX] Ingester: don't ignore errors encountered while iterating through chunks or samples in response to a query request. #6451
 * [BUGFIX] Fix issue where queries can fail or omit OOO samples if OOO head compaction occurs between creating a querier and reading chunks #6766
 * [BUGFIX] Fix issue where concatenatingChunkIterator can obscure errors #6766
