+# 1.10.1 / 2021-07-05
+
+This is an optional but **highly recommended** release of Lotus for lotus miners that has many bug fixes and improvements based on the feedback we got from the community since HyperDrive.
+
+## 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

+- `HotStoreFullGCFrequency` -- specifies how frequenty to garbage collect the hotstore

+  The default value is 20, which uses full GC every 20 compactions (about once a week);
+  set to 0 to disable full GC altogether.
+  Rationale: badger supports online GC, and this is used by default. However it has proven to
+  be ineffective in practice with the hotstore size slowly creeping up. In order to address this,
+  we have added moving GC support in our badger wrapper, which can effectively reclaim all space.
+  The downside is that it takes a bit longer to perform a moving GC and you also need enough
+  space to house the new hotstore while the old one is still live.
