Guiding Principles:
|
|
|
|
Changelogs are for humans, not machines.
|
|
There should be an entry for every single version.
|
|
The same types of changes should be grouped.
|
|
Versions and sections should be linkable.
|
|
The latest version comes first.
|
|
The release date of each version is displayed.
|
|
Mention whether you follow Semantic Versioning.
|
|
|
|
Usage:
|
|
|
|
Change log entries are to be added to the Unreleased section under the
|
|
appropriate stanza (see below). Each entry should ideally include a tag and
|
|
the Github issue reference in the following format:
|
|
|
|
* (<tag>) \#<issue-number> message
|
|
|
|
The issue numbers will later be link-ified during the release process so you do
|
|
not have to worry about including a link manually, but you can if you wish.
|
|
|
|
Types of changes (Stanzas):
|
|
|
|
"Features" for new features.
|
|
"Improvements" for changes in existing functionality.
|
|
"Deprecated" for soon-to-be removed features.
|
|
"Bug Fixes" for any bug fixes.
|
|
"Client Breaking" for breaking CLI commands and REST routes used by end-users.
|
|
"API Breaking" for breaking exported APIs used by developers building on SDK.
|
|
"State Machine Breaking" for any changes that result in a different AppState given same genesisState and txList.

### Improvements
|
|
|
|
* (sdk) [\#171](https://github.com/ChainSafe/ethermint/issues/177) Bump Cosmos SDK version to [v0.38.1](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.38.1) [@fedekunze](https://github.com/fedekunze):
|
|
* Add `x/evidence` module to ethermint app
|
|
* Bump Go requirement to 1.14+
|
|
* (`x/evm`) [\#181](https://github.com/ChainSafe/ethermint/issues/181) Updated EVM module to the recommended module structure. [@fedekunze](https://github.com/fedekunze)
|
|
* (app) [\#188](https://github.com/ChainSafe/ethermint/issues/186) Misc cleanup [@fedekunze](https://github.com/fedekunze):
|
|
* (`x/evm`) Rename `EthereumTxMsg` --> `MsgEthereumTx` and `EmintMsg` --> `MsgEthermint` for consistency with SDK standards
|
|
* Updated integration and unit tests to use `EthermintApp` as testing suite
|
|
* Use expected keeper interface for `AccountKeeper`
|
|
* Replaced `count` type in keeper with `int`
|
|
* Add SDK events for transactions
|
|
* [\#236](https://github.com/ChainSafe/ethermint/pull/236) Changes from upgrade [@fedekunze](https://github.com/fedekunze)
|
|
* (`app/ante`) Moved `AnteHandler` implementation to `app/ante`
|
|
* (keys) Marked `ExportEthKeyCommand` as **UNSAFE**
|
|
* (x/evm) Moved `BeginBlock` and `EndBlock` to `x/evm/abci.go`
|
|
* (`x/evm`) [\#255](https://github.com/ChainSafe/ethermint/pull/255) Add missing `GenesisState` fields and support `ExportGenesis` functionality.
|
|
* [\#272](https://github.com/ChainSafe/ethermint/pull/272) Add `Logger` for evm module.
|
|
* [\#317](https://github.com/ChainSafe/ethermint/pull/317) `GenesisAccount` validation.
|
|
* (`x/evm`) [\#319](https://github.com/ChainSafe/ethermint/pull/319) Verious evm improvements:
|
|
* Add transaction `[]*ethtypes.Logs` to evm's `GenesisState` to persist logs after an upgrade.
|
|
* Remove evm `CodeKey` and `BlockKey`in favor of a prefix `Store`.
|
|
* Set `BlockBloom` during `EndBlock` instead of `BeginBlock`.
|
|
* `Commit` state object and `Finalize` storage after `InitGenesis` setup.
|
|
* (rpc) [\#325](https://github.com/ChainSafe/ethermint/pull/325) `eth_coinbase` JSON-RPC query now returns the node's validator address.
|
|
|
|
### Features
|
|
|
|
* (rpc) [\#330](https://github.com/ChainSafe/ethermint/issues/330) Implement `PublicFilterAPI`'s `EventSystem` which subscribes to Tendermint events upon `Filter` creation.
|
|
* (rpc) [\#231](https://github.com/ChainSafe/ethermint/issues/231) Implement `NewBlockFilter` in rpc/filters.go which instantiates a polling block filter
|
|
* Polls for new blocks via `BlockNumber` rpc call; if block number changes, it requests the new block via `GetBlockByNumber` rpc call and adds it to its internal list of blocks
|
|
* Update uninstallFilter and getFilterChanges accordingly
|
|
* uninstallFilter stops the polling goroutine
|
|
* getFilterChanges returns the filter's internal list of block hashes and resets it
|
|
* (rpc) [\#54](https://github.com/ChainSafe/ethermint/issues/54), [\#55](https://github.com/ChainSafe/ethermint/issues/55)
|
|
Implement `eth_getFilterLogs` and `eth_getLogs`:
|
|
* For a given filter, look through each block for transactions. If there are transactions in the block, get the logs from it, and filter using the filterLogs method
|
|
* `eth_getLogs` and `eth_getFilterChanges` for log filters use the same underlying method as `eth_getFilterLogs`
|
|
* update `HandleMsgEthereumTx` to store logs using the ethereum hash
|
|
* (app) [\#187](https://github.com/ChainSafe/ethermint/issues/187) Add support for simulations.
|
|
|
|
### Bug Fixes
|
|
|
|
* (rpc) [\#305](https://github.com/ChainSafe/ethermint/issues/305) Update eth_getTransactionCount to check for account existence before getting sequence and return 0 as the nonce if it doesn't exist.
|
|
* (`x/evm`) [\#319](https://github.com/ChainSafe/ethermint/pull/319) Fix `SetBlockHash` that was setting the incorrect height during `BeginBlock`.
|
|
* (x/evm) [\#176](https://github.com/ChainSafe/ethermint/issues/176) Updated Web3 transaction hash from using RLP hash. Now all transaction hashes exposed are amino hashes.
|
|
* Removes `Hash()` (RLP) function from `MsgEthereumTx` to avoid confusion or misuse in future. |
