-
-## 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)

-# 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

+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). 

 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.

-# 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.
