 * [CHANGE] Increased default configuration for `-server.grpc-max-recv-msg-size-bytes` and `-server.grpc-max-send-msg-size-bytes` from 4MB to 100MB. #1883
 * [ENHANCEMENT] Store-gateway: Add the experimental ability to run requests in a dedicated OS thread pool. This feature can be configured using `-store-gateway.thread-pool-size` and is disabled by default. Replaces the ability to run index header operations in a dedicated thread pool. #1660 #1812
+* [ENHANCEMENT] Memberlist KV: incoming messages are now processed on per-key goroutine. This may reduce loss of "maintanance" packets in busy memberlist installations, but use more CPU. New `memberlist_client_received_broadcasts_dropped_total` counter tracks number of dropped per-key messages. #1912
 * [BUGFIX] Fix regexp parsing panic for regexp label matchers with start/end quantifiers. #1883
 * [BUGFIX] Ingester: fixed deceiving error log "failed to update cached shipped blocks after shipper initialisation", occurring for each new tenant in the ingester. #1893
