|
|
|
|
A patch release, containing a few nice bugfixes and improvements:
|
|
|
|
- Fix parsing of peer ID in `lotus-miner actor set-peer-id` (@whyrusleeping)

|
|
|
|
# 0.5.3
|
|
|
|
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).
