+# Lotus changelog
+
+## 0.5.0 / 2020-08-2020
+
+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).
+
