 # Lotus changelog
 
+# 1.1.2 / 2020-10-24
+

+
+# 1.1.0 / 2020-10-20
+
+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)
+- Update markets v1.0.0 (https://github.com/filecoin-project/lotus/pull/4505)
+- Add some extra logging to try and debug sync issues (https://github.com/filecoin-project/lotus/pull/4486)

+- Add a comment to BlockMessages to address #4446 (https://github.com/filecoin-project/lotus/pull/4491)
+
+# 1.0.0 / 2020-10-19
+
+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).
+
+## Changes
+

+- Add command to (slowly) prune lotus chain datastore (https://github.com/filecoin-project/lotus/pull/3876)
+- Add WalletVerify to lotus-gateway (https://github.com/filecoin-project/lotus/pull/4373)
+- Improve StateMsg APIs (https://github.com/filecoin-project/lotus/pull/4429)
+- Add endpoints needed by spacegap (https://github.com/filecoin-project/lotus/pull/4426)
+- Make audit balances capable of printing robust addresses (https://github.com/filecoin-project/lotus/pull/4423)

 ## Reporting a Vulnerability
 
-For *critical* bugs, please send an email to security@filecoin.org.

-The bug reporting process differs between bugs that are critical and may crash the network, and others that are unlikely to cause problems if malicious parties know about it. For non-critical bugs, please simply file a GitHub [issue](https://github.com/filecoin-project/lotus/issues/new?template=bug_report.md). 
+For *critical* bugs, please consult our Security Policy and Responsible Disclosure Program information at https://github.com/filecoin-project/community/blob/master/SECURITY.md
 
 Please try to provide a clear description of any bugs reported, along with how to reproduce the bug if possible. More detailed bug reports (especially those with a PoC included) will help us move forward much faster. Additionally, please avoid reporting bugs that already have open issues. Take a moment to search the issue list of the related GitHub repositories before writing up a new report.
