- **Experimental** [lotus-miner market subsystem](https://docs.filecoin.io/mine/lotus/split-markets-miners/#frontmatter-title)
- **Under Testing** [splistore](https://github.com/filecoin-project/lotus/blob/master/blockstore/splitstore/README.md)
+This is a  **highly recommended** but optional Lotus v1.11.1 release that introduces many deal making and datastore improvements and new features along with other bug fixes. 

- github.com/filecoin-project/lotus:
-  - Merge branch 'releases' into release/v1.11.1
-  - Update to proof v8.0.3 ([filecoin-project/lotus#6890](https://github.com/filecoin-project/lotus/pull/6890))
+## 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!
+  - More details on the concepts, architecture and how to split the market process can be found [here](https://docs.filecoin.io/mine/lotus/split-markets-miners/#concepts). 
+  - Base on your system setup(running on separate machines, same machine and so on), please see the suggested practice by community members [here](https://github.com/filecoin-project/lotus/discussions/7047#discussion-3515335).
+    - Note: if you are running lotus-worker on a different machine, you will need to set `MARKETS_API_INFO` for certain CLI to work properly. This will be improved by #7072.
+  - Huge thanks to MinerX fellows for [helping testing the implementation, reporting the issues so they were fixed by now and providing feedbacks](https://github.com/filecoin-project/lotus/discussions/6861) to user docs in the past three weeks!
+- Config for collateral from miner available balance ([filecoin-project/lotus#6629](https://github.com/filecoin-project/lotus/pull/6629)) 
+  - Better control your sector collateral payment by setting `CollateralFromMinerBalance`, `AvailableBalanceBuffer` and `DisableCollateralFallback`.
+    - `CollateralFromMinerBalance`:  whether to use available miner balance for sector collateral instead of sending it with each message, default is `false`.
+    - `AvailableBalanceBuffer`: minimum available balance to keep in the miner actor before sending it with messages, default is 0FIL.
+    - `DisableCollateralFallback`: whether to send collateral with messages even if there is no available balance in the miner actor, default is `false`.
+- Config for deal publishing control addresses ([filecoin-project/lotus#6697](https://github.com/filecoin-project/lotus/pull/6697))
+  - Set `DealPublishControl` to set the wallet used for sending `PublishStorageDeals` messages, instructions [here](https://docs.filecoin.io/mine/lotus/miner-addresses/#control-addresses).
+- Config UX improvements ([filecoin-project/lotus#6848](https://github.com/filecoin-project/lotus/pull/6848))
+  - You can now preview the the default and updated node config by running `lotus/lotus-miner config default/updated`  
+

-### DagstoreInitializeShard
-DagstoreInitializeShard initializes an uninitialized shard.
-
-Initialization consists of fetching the shard's data (deal payload) from
-the storage subsystem, generating an index, and persisting the index
-to facilitate later retrievals, and/or to publish to external sources.
-
-This operation is intended to complement the initial migration. The
-migration registers a shard for every unique piece CID, with lazy
-initialization. Thus, shards are not initialized immediately to avoid
-IO activity competing with proving. Instead, shard are initialized
-when first accessed. This method forces the initialization of a shard by
-accessing it and immediately releasing it. This is useful to warm up the
-cache to facilitate subsequent retrievals, and to generate the indexes
-to publish them externally.
-
-This operation fails if the shard is not in ShardStateNew state.
-It blocks until initialization finishes.
