This allows interacting with contracts on live chains with a compatible [`pallet-contracts`](https://github.com/paritytech/substrate/tree/master/frame/contracts). For command-line examples on how to use these commands see [#79](https://github.com/paritytech/cargo-contract/pull/79). ### Linting rules for smart contracts We are introducing a linter for ink! smart contracts in this release! From now on `cargo-contract` checks if the ink! smart contract that is `build` or `check`-ed follows certain rules. As a starting point we've only added one linting rule so far; it asserts correct initialization of the [`ink_storage::Mapping`](https://paritytech.github.io/ink/ink_storage/struct.Mapping.html) data structure. In order for the linting to work with your smart contract, the contract has to be written in at least ink! 3.0.0-rc9. If it's older the linting will just always succeed. ### Added - Interact with contracts: upload, instantiate and call commands - [#79](https://github.com/paritytech/cargo-contract/pull/79) - Add linting to assert correct initialization of [`ink_storage::Mapping`](https://paritytech.github.io/ink/ink_storage/struct.Mapping.html) - [#431](https://github.com/paritytech/cargo-contract/pull/431) ### Changed - Upgrade `subxt`, SCALE crates, and substrate primitive `sp-*` crates [#451](https://github.com/paritytech/cargo-contract/pull/451). - Updated `cargo contract new` template dependencies to ink!
