v3.2.0

[3.2.0]

This release allows building contracts with recent (> 1.69) Rust toolchains which can emit
signext Wasm instructions. An extra pass is added to wasm-opt which "lowers" signext
instructions to MVP compatible instructions. The resulting binaries can therefore be
deployed to chains with an older version of pallet-contracts which does not yet support
those instructions.

Changed

• Backport SignextLowering #1189 + #1280 - #1286

v4.0.0-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.

• 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

Changed

• Display build progress with --output-json, print to stderr - 1211
