 * [CHANGE] Ruler: removed `-ruler.enable-sharding` option, and change default value of `-ruler.ring.store` to `memberlist`. #943
 * [CHANGE] Ruler: `-ruler.alertmanager-use-v2` now defaults to `true`. #954
 * [CHANGE] Compactor: Removed `-compactor.sharding-enabled` option. Sharding in compactor is now always enabled. Default value of `-compactor.ring.store` has changed from `consul` to `memberlist`. Default value of `-compactor.ring.wait-stability-min-duration` is now 0, which disables the feature. #956

Mimir now behaves like if `-querier.worker-match-max-concurrent` is always enabled and you should configure the max concurrency per querier process using `-querier.max-concurrent` instead. #958
