+
+This is a mandatory release that introduces the first post-liftoff upgrade to the Filecoin network. The changes that break consensus are an upgrade to specs-actors v2.2.0 at epoch 170000.
+
+## Changes
+
+- Introduce Network version 6 (https://github.com/filecoin-project/lotus/pull/4506)

+It's 1.0.0! This is an optional release of Lotus that introduces some UX improvements to the 0.10 series.
+
+This very small release is largely cosmetic, and intended to flag the code that the Filecoin mainnet was launched with.
+
+## API changes
+
+- `StateMsgGasCost` has been removed. The equivalent information can be gained by calling `StateReplay`.
+- A `GasCost` field has been added to the `InvocResult` type, meaning detailed gas costs will be returned when calling `StateReplay`, `StateCompute`, and `StateCall`.
+- The behaviour of `StateReplay` in response to an empty tipset key has been changed. Instead of simply using the heaviest tipset (which is almost guaranteed to be an unsuccessful replay), we search now search the chain for the tipset that included the message, and replay the message in that tipset (we fail if no such tipset is found).

 # 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.
