[4.0.0-alpha]

Replaces the yanked 3.1.0 due to issues with supporting both Rust versions < 1.70 and >= 1.70.

If you intend to use cargo-contract with Rust >= 1.70, and deploy to a node with a version of pallet-contracts at least polkadot-1.0.0, then this is the release to use.

If you still want to compile with 1.69 and target an older version of pallet-contracts then use the previous 3.0.1 release.

Interact with contracts: upload, instantiate and call commands

We added commands to upload, instantiate and call contracts! This allows interacting with contracts on live chains with a compatible pallet-contracts.

For command-line examples on how to use these commands see #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 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.
