 # Lotus changelog
 
+# 0.7.2 / 2020-09-23
+
+This optional release of Lotus introduces a major refactor around how a Lotus node interacts with code from the specs-actors repo. We now use interfaces to read the state of actors, which is required to be able to reason about different versions of actors code at the same time.
+
+Additionally, this release introduces various improvements to the sync process, as well as changes to better the overall UX experience.
+
+## Changes
+
+#### Core Lotus
+
+- Network upgrade support (https://github.com/filecoin-project/lotus/pull/3781)
+- Upgrade markets to `v0.6.2` (https://github.com/filecoin-project/lotus/pull/3974)
+- Validate chain sync response indices when fetching messages (https://github.com/filecoin-project/lotus/pull/3939)
+- Add height diff to sync wait (https://github.com/filecoin-project/lotus/pull/3926)
+- Replace Requires with Wants (https://github.com/filecoin-project/lotus/pull/3898)
+- Update state diffing for market actor (https://github.com/filecoin-project/lotus/pull/3889)
+- Parallel fetch for sync (https://github.com/filecoin-project/lotus/pull/3887)
+- Fix SectorState (https://github.com/filecoin-project/lotus/pull/3881)
+
+#### User Experience
+
+- Add basic deal stats api server for spacerace slingshot (https://github.com/filecoin-project/lotus/pull/3963)
+- When doing `sectors update-state`, show a list of existing states if user inputs an invalid one (https://github.com/filecoin-project/lotus/pull/3944)
+- Fix `lotus-miner storage find` error (https://github.com/filecoin-project/lotus/pull/3927)
+- Log shutdown method for lotus daemon and miner (https://github.com/filecoin-project/lotus/pull/3925)
+- Update build and setup instruction link (https://github.com/filecoin-project/lotus/pull/3919)
+- Add an option to hide removed sectors from `sectors list` output (https://github.com/filecoin-project/lotus/pull/3903)
+
+#### Testing and validation
+
+- Add init.State#Remove() for testing (https://github.com/filecoin-project/lotus/pull/3971)
+- lotus-shed: add consensus check command (https://github.com/filecoin-project/lotus/pull/3933)
+- Add keyinfo verify and jwt token command to lotus-shed (https://github.com/filecoin-project/lotus/pull/3914)
+- Fix conformance gen (https://github.com/filecoin-project/lotus/pull/3892)
+
 # 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.

+# Actors
+
+This package contains shims for abstracting over different actor versions.
+
+## Design
+
+Shims in this package follow a few common design principles.
+
+### Structure Agnostic
+
+Shims interfaces defined in this package should (ideally) not change even if the
+structure of the underlying data changes. For example:
+
+* All shims store an internal "store" object. That way, state can be moved into
+  a separate object without needing to add a store to the function signature.
+* All functions must return an error, even if unused for now.
+
+### Minimal
+
+These interfaces should be expanded only as necessary to reduce maintenance burden.
+
+### Queries, not field assessors.
+
+When possible, functions should query the state instead of simply acting as
+field assessors. These queries are more likely to remain stable across
+specs-actor upgrades than specific state fields.
+
+Note: there is a trade-off here. Avoid implementing _complicated_ query logic
+inside these shims, as it will need to be replicated in every shim.

+
+   The height flag specifies a chain height to start a comparison from. There are two special

+
+   @common   - Use the maximum common chain height between all nodes
+   @expected - Use the current time and the genesis timestamp to determine a height
+
+   Examples
+
+   Find the highest common tipset and look back 10 tipsets
+   lotus-shed consensus check --height @common --lookback 10
+
+   Calculate the expected tipset height and look back 10 tipsets
+   lotus-shed consensus check --height @expected --lookback 10
+
+   Check if nodes all share a common genesis
