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.

Notable changes:

  • Verifiable builds inside a docker container - #1148
  • Extrinsics extracted to separate crate - #1181
  • Fix building contracts with Rust >= 1.70: enable sign_ext Wasm opcode - #1189
