 # Lotus changelog
 
+# 1.10.0 / 2021-06-23
+
+This is a mandatory release of Lotus that introduces Filecoin network v13, codenamed the HyperDrive upgrade. The
+Filecoin mainnet will upgrade, which is epoch 892800, on 2021-06-30T22:00:00Z. The network upgrade introduces the
+following FIPs:
+
+- [FIP-0008](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0008.md): Add miner batched sector pre-commit method
+- [FIP-0011](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0011.md): Remove reward auction from reporting consensus faults
+- [FIP-0012](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0012.md): DataCap Top up for FIL+ Client Addresses
+- [FIP-0013](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0013.md): Add ProveCommitSectorAggregated method to reduce on-chain congestion
+- [FIP-0015](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0015.md): Revert FIP-0009(Exempt Window PoSts from BaseFee burn)
+
+Note that this release is built on top of Lotus v1.9.0. Enterprising users can use the `master` branch of Lotus to get the latest functionality, including all changes in this release candidate.
+
+## Proof batching and aggregation
+
+FIPs [0008](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0008.md) and [0013](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0013.md) combine to allow for a significant increase in the rate of onboarding storage on the Filecoin network. This aims to lead to more useful data being stored on the network, reduced network congestion, and lower network base fee.
+
+**Check out the documentation [here](https://docs.filecoin.io/mine/lotus/miner-configuration/#precommitsectorsbatch) for details on the new Lotus miner sealing config options, [here](https://docs.filecoin.io/mine/lotus/miner-configuration/#fees-section) for fee config options, and explanations of the new features.**
+
+Note:
+  - We recommend to keep `PreCommitSectorsBatch` as 1.
+  - We recommend miners to set `PreCommitBatchWait` lower than 30 hours.
+  - We recommend miners to set a longer `CommitBatchSlack` and  `PreCommitBatchSlack` to prevent message failures
+    due to expirations.
+
+### Projected state tree growth
+
+In order to validate the Hyperdrive changes, we wrote a simulation to seal as many sectors as quickly as possible, assuming the same number and mix of 32GiB and 64GiB miners as the current network.
+
+Given these assumptions:
+
+- We'd expect a network storage growth rate of around 530PiB per day. 😳 🎉 🥳 😅
+- We'd expect network bandwidth dedicated to `SubmitWindowedPoSt` to grow by about 0.02% per day.
+- We'd expect the [state-tree](https://spec.filecoin.io/#section-systems.filecoin_vm.state_tree) (and therefore [snapshot](https://docs.filecoin.io/get-started/lotus/chain/#lightweight-snapshot)) size to grow by 1.16GiB per day.
+   - Nearly all of the state-tree growth is expected to come from new sector metadata.
+- We'd expect the daily lotus datastore growth rate to increase by about 10-15% (from current ~21GiB/day).
+   - Most "growth" of the lotus datastore is due to "churn", historical data that's no longer referenced by the latest state-tree.
+
+### Future improvements
+
+Various Lotus improvements are planned moving forward to mitigate the effects of the growing state tree size. The primary improvement is the [Lotus splitstore](https://github.com/filecoin-project/lotus/discussions/5788), which will soon be enabled by default. The feature allows for [online garbage collection](https://github.com/filecoin-project/lotus/issues/6577) for nodes that do not seek to maintain full chain and state history, thus eliminating the need for users to delete their datastores and sync from snapshots.
+
+Other improvements including better compressed snapshots, faster pre-migrations, and improved chain exports are in the roadmap.
+
+## WindowPost base fee burn
+
+Included in the HyperDrive upgrade is [FIP-0015](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0015.md) which eliminates the special-case gas treatment of `SubmitWindowedPoSt` messages that was introduced in [FIP-0009](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0009.md). Although `SubmitWindowedPoSt` messages will be relatively cheap, thanks to the introduction of optimistic acceptance of these proofs in [FIP-0010](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0010.md), storage providers should pay attention to their `MaxWindowPoStGasFee` config option: too low and PoSts may not land on chain; too high and they may cost an exorbitant amount!
