-# 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)
- Circle: Run tests for some subsystems separately (https://github.com/filecoin-project/lotus/pull/4496)
- Add a terminate sectors command to lotus-shed (https://github.com/filecoin-project/lotus/pull/4507)
- 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

-## Related packages
+## Development

-These repos are independent and reusable modules, but are tightly integrated into Lotus to make up a fully featured Filecoin implementation:
+The main branches under development at the moment are:
+* [`master`](https://github.com/filecoin-project/lotus): current testnet.
+* [`next`](https://github.com/filecoin-project/lotus/tree/next): working branch with chain-breaking changes.
+* [`ntwk-calibration`](https://github.com/filecoin-project/lotus/tree/ntwk-calibration): devnet running one of `next` commits.

+### Tracker
+
+All work is tracked via issues. An attempt at keeping an up-to-date view on remaining work towards Mainnet launch can be seen at the [lotus github project board](https://github.com/orgs/filecoin-project/projects/8). The issues labeled with `incentives` are there to identify the issues needed for Space Race launch.
+
+### Packages
+
+The lotus Filecoin implementation unfolds into the following packages:
+
+- [This repo](https://github.com/filecoin-project/lotus)
 - [go-fil-markets](https://github.com/filecoin-project/go-fil-markets) which has its own [kanban work tracker available here](https://app.zenhub.com/workspaces/markets-shared-components-5daa144a7046a60001c6e253/board)

-## Contribute
-
-Lotus is a universally open project and welcomes contributions of all kinds: code, docs, and more. However, before making a contribution, we ask you to heed these recommendations:
-
-1. If the proposal entails a protocol change, please first submit a [Filecoin Improvement Proposal](https://github.com/filecoin-project/FIPs).
-2. If the change is complex and requires prior discussion, [open an issue](github.com/filecoin-project/lotus/issues) or a [discussion](https://github.com/filecoin-project/lotus/discussions) to request feedback before you start working on a pull request. This is to avoid disappointment and sunk costs, in case the change is not actually needed or accepted.
-3. Please refrain from submitting PRs to adapt existing code to subjective preferences. The changeset should contain functional or technical improvements/enhancements, bug fixes, new features, or some other clear material contribution. Simple stylistic changes are likely to be rejected in order to reduce code churn.
-
-When implementing a change:
-
-1. Adhere to the standard Go formatting guidelines, e.g. [Effective Go](https://golang.org/doc/effective_go.html). Run `go fmt`.
-2. Stick to the idioms and patterns used in the codebase. Familiar-looking code has a higher chance of being accepted than eerie code. Pay attention to commonly used variable and parameter names, avoidance of naked returns, error handling patterns, etc.
-3. Comments: follow the advice on the [Commentary](https://golang.org/doc/effective_go.html#commentary) section of Effective Go.
-4. Minimize code churn. Modify only what is strictly necessary. Well-encapsulated changesets will get a quicker response from maintainers.
-5. Lint your code with [`golangci-lint`](https://golangci-lint.run) (CI will reject your PR if unlinted).
-6. Add tests.
-7. Title the PR in a meaningful way and describe the rationale and the thought process in the PR description.
-8. Write clean, thoughtful, and detailed [commit messages](https://chris.beams.io/posts/git-commit/). This is even more important than the PR description, because commit messages are stored _inside_ the Git history. One good rule is: if you are happy posting the commit message as the PR description, then it's a good commit message.

 ## Reporting a Vulnerability

-For reporting security vulnerabilities/bugs, please consult our Security Policy and Responsible Disclosure Program information at https://github.com/filecoin-project/community/blob/master/SECURITY.md. Security vulnerabilities should be reported via our [Vulnerability Reporting channels](https://github.com/filecoin-project/community/blob/master/SECURITY.md#vulnerability-reporting) and will be eligible for a [Bug Bounty](https://security.filecoin.io/bug-bounty/).
+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.
