 # Lotus changelog

-# 1.11.1 / 2021-08-16
-
-> Note: for discussion about this release, please comment [here](https://github.com/filecoin-project/lotus/discussions/6904)
-
-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. 
-
-## 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`

-## New Features
- commit batch: AggregateAboveBaseFee config #6650
-  - `AggregateAboveBaseFee` is added to miner sealing configuration for setting the network base fee to start aggregating proofs. When the network base fee is lower than this value, the prove commits will be submitted individually via `ProveCommitSector`. According to the [Batch Incentive Alignment](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0013.md#batch-incentive-alignment) introduced in FIP-0013, we recommend miners to set this value to 0.15 nanoFIL(which is the default value) to avoid unexpected aggregation fee in burn and enjoy the most benefits of aggregation!
-    
-## Bug Fixes
- storage: Fix FinalizeSector with sectors in storage paths #6652
- Fix tiny error in check-client-datacap #6664  
- Fix: precommit_batch method used the wrong cfg.PreCommitBatchWait #6658
- to optimize the batchwait #6636
- fix getTicket: sector precommitted but expired case #6635
- handleSubmitCommitAggregate() exception handling #6595
- remove precommit check in handleCommitFailed #6634
- ensure agg fee is adequate
- fix: miner balance is not enough, so that ProveCommitAggregate msg exec failed #6623
- commit batch: Initialize the FailedSectors map #6647
