-Yet another hotfix release. 
-A lesson for readers, having people who have been awake for 12+ hours review
-your hotfix PR is not a good idea. Find someone who has enough slept recently
-enough to give you good code review, otherwise you'll end up quickly bumping
-versions again.
-
- Fixed a bug in the mempool that was introduced in v0.5.2
-
-# 0.5.2 / 2020-08-24
-
-This is a hotfix release.
-
- Fix message selection to not include messages that are invalid for block
-  inclusion.
- Improve SelectMessage handling of the case where the message pools tipset
-  differs from our mining base.
-
-# 0.5.1 / 2020-08-24
-
-The Space Race release! 
-This release contains the genesis car file and bootstrap peers for the space
-race network. 
-
-Additionally, we included two small fixes to genesis creation:
- Randomize ticket value in genesis generation
- Correctly set t099 (burnt funds actor) to have valid account actor state
-
-# 0.5.0 / 2020-08-20
-
-This version of Lotus will be used for the incentivized testnet Space Race competition,
-and can be considered mainnet-ready code. It includes some protocol
-changes, upgrades of core dependencies, and various bugfixes and UX/performance improvements.
-
-## Highlights
-
-Among the highlights included in this release are:
-
- Gas changes: We implemented EIP-1559 and introduced real gas values.
- Deal-making: We now support "Committed Capacity" sectors, "fast-retrieval" deals,
-and the packing of multiple deals into a single sector.
- Renamed features: We renamed some of the binaries, environment variables, and default
-paths associated with a Lotus node.
-
-### Gas changes
-
-We made some significant changes to the mechanics of gas in this release.
-
-#### Network fee
-
-We implemented something similar to 
-[Ethereum's EIP-1559](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md).
-The `Message` structure had three changes:
- The `GasPrice` field has been removed
- A new `GasFeeCap` field has been added, which controls the maximum cost
-the sender incurs for the message
- A new `GasPremium` field has been added, which controls the reward a miner
-earns for including the message
-
-A sender will never be charged more than `GasFeeCap * GasLimit`. 
-A miner will typically earn `GasPremium * GasLimit` as a reward.
-
-The `Blockheader` structure has one new field, called `ParentBaseFee`. 
-Informally speaking,the `ParentBaseFee`
-is increased when blocks are densely packed with messages, and decreased otherwise.
-
-The `ParentBaseFee` is used when calculating how much a sender burns when executing a message. _Burning_ simply refers to sending attoFIL to a dedicated, unreachable account.
-A message causes `ParentBaseFee * GasUsed` attoFIL to be burnt.
-
-#### Real gas values
-
-This release also includes our first "real" gas costs for primitive operations.
-The costs were designed to account for both the _time_ that message execution takes,
-as well as the _space_ a message adds to the state tree.
-
-## Deal-making changes
-
-There are three key changes to the deal-making process.
-
-#### Committed Capacity sectors
-
-Miners can now pledge "Committed Capacity" (CC) sectors, which are explicitly
-stated as containing junk data, and must not include any deals. Miners can do this
-to increase their storage power, and win block rewards from this pledged storage.
-
-They can mark these sectors as "upgradable" with `lotus-miner sectors mark-for-upgrade`.
-If the miner receives and accepts one or more storage deals, the sector that includes
-those deals will _replace_ the CC sector. This is intended to maximize the amount of useful
-storage on the Filecoin network.
-
-#### Fast-retrieval deals
-
-Clients can now include a `fast-retrieval` flag when proposing deals with storage miners.
-If set to true, the miner will include an extra copy of the deal data. This
-data can be quickly served in a retrieval deal, since it will not need to be unsealed.
-
-#### Multiple deals per sector
-
-Miners can now pack multiple deals into a single sector, so long as all the deals
-fit into the sector capacity. This should increase the packing efficiency of miners.
-
-### Renamed features
-
-To improve the user experience, we updated several names to mainatin
-standard prefixing, and to better reflect the meaning of the features being referenced.
-
-In particular, the Lotus miner binary is now called `lotus-miner`, the default
-path for miner data is now `~/.lotusminer`, and the environment variable
-that sets the path for miner data is now `$LOTUS_MINER_PATH`. A full list of renamed
-features can be found [here](https://github.com/filecoin-project/lotus/issues/2304).

-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.

+## Building & Documentation

-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.

-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)

-## Reporting a Vulnerability
-
-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.
-
-Here are some examples of bugs we would consider 'critical':
-
-* If you can spend from a `multisig` wallet you do not control the keys for.
-* If you can cause a miner to be slashed without them actually misbehaving.
-* If you can maintain power without submitting windowed posts regularly.
-* If you can craft a message that causes lotus nodes to panic.
-* If you can cause your miner to win significantly more blocks than it should.
-* If you can craft a message that causes a persistent fork in the network.
-* If you can cause the total amount of Filecoin in the network to no longer be 2 billion.
-
-This is not an exhaustive list, but should provide some idea of what we consider 'critical'.

-# 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.
