 # Lotus changelog
 
+# 0.7.1 / 2020-09-17
+
+This optional release of Lotus introduces some critical fixes to the window PoSt process. It also upgrades some core dependencies, and introduces many improvements to the mining process, deal-making cycle, and overall User Experience.
+
+## Changes
+
+#### Some notable improvements: 
+
+- Correctly construct params for `SubmitWindowedPoSt` messages (https://github.com/filecoin-project/lotus/pull/3909)
+- Skip sectors correctly for Window PoSt (https://github.com/filecoin-project/lotus/pull/3839)
+- Split window PoST submission into multiple messages (https://github.com/filecoin-project/lotus/pull/3689)
+- Improve journal coverage (https://github.com/filecoin-project/lotus/pull/2455)
+- Allow retrievals while sealing (https://github.com/filecoin-project/lotus/pull/3778)
+- Don't prune locally published messages (https://github.com/filecoin-project/lotus/pull/3772)
+- Add get-ask, set-ask retrieval commands (https://github.com/filecoin-project/lotus/pull/3886)
+- Consistently name winning and window post in logs (https://github.com/filecoin-project/lotus/pull/3873))
+- Add auto flag to mpool replace (https://github.com/filecoin-project/lotus/pull/3752))
+
+#### Dependencies
+
+- Upgrade markets to `v0.6.1` (https://github.com/filecoin-project/lotus/pull/3906)
+- Upgrade specs-actors to `v0.9.10` (https://github.com/filecoin-project/lotus/pull/3846)
+- Upgrade badger (https://github.com/filecoin-project/lotus/pull/3739)
+
+# 0.7.0 / 2020-09-10
+
+This consensus-breaking release of Lotus is designed to test a network upgrade on the space race testnet. The changes that break consensus are:
+
+- Upgrading the Drand network used from the test Drand network to the League of Entropy main drand network. This is the same Drand network that will be used in the Filecoin mainnet.
+- Upgrading to specs-actors v0.9.8, which adds a new method to the Multisig actor.
+
+## Changes
+
+#### Core Lotus
+
+- Fix IsAncestorOf (https://github.com/filecoin-project/lotus/pull/3717)
+- Update to specs-actors v0.9.8 (https://github.com/filecoin-project/lotus/pull/3725)
+- Increase chain throughput by 20% (https://github.com/filecoin-project/lotus/pull/3732)
+- Updare to go-libp2p-pubsub `master` (https://github.com/filecoin-project/lotus/pull/3735)
+- Drand upgrade (https://github.com/filecoin-project/lotus/pull/3670)
+- Multisig API additions (https://github.com/filecoin-project/lotus/pull/3590)
+
+#### Storage Miner 
+
+- Increase the number of times precommit2 is attempted before moving back to precommit1 (https://github.com/filecoin-project/lotus/pull/3720)
+
+#### Message pool
+
+- Relax mpool add strictness checks for local pushes (https://github.com/filecoin-project/lotus/pull/3724)
+
+
+#### Maintenance
+
+- Fix devnets (https://github.com/filecoin-project/lotus/pull/3712)
+- Fix(chainwatch): compare prev miner with cur miner (https://github.com/filecoin-project/lotus/pull/3715)
+- CI: fix statediff build; make optional (https://github.com/filecoin-project/lotus/pull/3729)
+- Feat: Chaos abort (https://github.com/filecoin-project/lotus/pull/3733)
