# Changelog
|
|
|
|
All notable changes to this project will be documented in this file.
|
|
|
|
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
|
|
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
|
|
|
The semantic versioning guarantees cover the interface to the substrate runtime which
|
|
includes this pallet as a dependency. This module will also add storage migrations whenever
|
|
changes require it. Stability with regard to offchain tooling is explicitly excluded from
|
|
this guarantee: For example adding a new field to an in-storage data structure will require
|
|
changes to frontends to properly display it. However, those changes will still be regarded
|
|
as a minor version bump.
|
|
|
|
The interface provided to smart contracts will adhere to semver with one exception: Even
|
|
major version bumps will be backwards compatible with regard to already deployed contracts.
|
|
In other words: Upgrading this pallet will not break pre-existing contracts.
|
|
|
|
## [v3.0.0]
|
|
|
|
This version constitutes the first release that brings any stability guarantees (see above).
|
|
|
|
### Added
|
|
|
|
- Emit an event when a contract terminates (self-destructs).
|
|
[1](https://github.com/paritytech/substrate/pull/8014)
|
|
|
|
- Charge rent for code stored on the chain in addition to the already existing
|
|
rent that is payed for data storage.
|
|
[1](https://github.com/paritytech/substrate/pull/7935)
|
|
|
|
- Allow the runtime to configure per storage item costs in addition
|
|
to the already existing per byte costs.
|
|
[1](https://github.com/paritytech/substrate/pull/7819)
|
|
|
|
- Contracts are now deleted lazily so that the user who removes a contract
|
|
does not need to pay for the deletion of the contract storage.
|
|
[1](https://github.com/paritytech/substrate/pull/7740)
|
|
|
|
- Allow runtime authors to define chain extensions in order to provide custom
|
|
functionality to contracts.
|
|
[1](https://github.com/paritytech/substrate/pull/7548)
|
|
[2](https://github.com/paritytech/substrate/pull/8003)
|
|
|
|
- Proper weights which are fully automated by benchmarking.
|
|
[1](https://github.com/paritytech/substrate/pull/6715)
|
|
[2](https://github.com/paritytech/substrate/pull/7017)
|
|
[3](https://github.com/paritytech/substrate/pull/7361)
|
|
|
|
### Changes
|
|
|
|
- Collect the rent for one block during instantiation.
|
|
[1](https://github.com/paritytech/substrate/pull/7847)
|
|
|
|
- Instantiation takes a `salt` argument to allow for easier instantion of the
|
|
same code by the same sender.
|
|
[1](https://github.com/paritytech/substrate/pull/7482)
|
|
|
|
- Improve the information returned by the `contracts_call` RPC.
|
|
[1](https://github.com/paritytech/substrate/pull/7468)
|
|
|
|
- Simplify the node configuration necessary to add this module.
|
|
[1](https://github.com/paritytech/substrate/pull/7409)
|
|
|
|
### Fixed
|
|
|
|
- Consider the code size of a contract in the weight that is charged for
|
|
loading a contract from storage.
|
|
[1](https://github.com/paritytech/substrate/pull/8086)
|
|
|
|
- Fix possible overflow in storage size calculation
|
|
[1](https://github.com/paritytech/substrate/pull/7885)
|
|
|
|
- Cap the surcharge reward that can be claimed.
|
|
[1](https://github.com/paritytech/substrate/pull/7870)
|
|
|
|
- Fix a possible DoS vector where contracts could allocate too large buffers.
