+This is a *highly recommended* optional release for storage providers that are doing snap deals. This fix the bug
+that causes some snap deal sectors are stuck in `FinalizeReplicaUpdate`. In addition, SPs should be able to force
+update sectors status without getting blocked by `normal shutdown of state machine`.

-    - `SimultaneousTransfer` is now replaced by `SimultaneousTransfersForStorage` and `SimultaneousTransfersForRetrieval`, where users may set the amount of ongoing data transfer for storage and retrieval deals in parallel separately. The default value for both is set to 20. 
-    - If you are using the lotus client, these two configuration variables are under the `Client` section in `./lotus/config.toml`.

 ## Highlights
 - ⭐️⭐️⭐️[**lotus-miner market subsystem**](https://docs.filecoin.io/mine/lotus/split-markets-miners/#frontmatter-title) is introduced in this release! It is **highly recommended** for storage providers to run markets processes on a separate machine! Doing so, only this machine needs to exposes public ports for deal making. This also means that the other miner operations can now be completely isolated by from the deal making processes and storage providers can stop and restarts the markets process without affecting an ongoing Winning/Window PoSt!
