This release allows building contracts with recent (> 1.69) Rust toolchains which can emit
signext
Wasm instructions. An extra pass is added towasm-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 supportthose instructions.
