v5.0.0

This release concludes the migration of ink! from Parity to the outside world. It doesn't come with any new features, we just:

• …changed the Parity URLs to ones for our new GitHub organization
  @use-ink.
• …upgraded many dependencies to newer versions, which results in two particular
  breaking changes regarding compatibility:
  • We had to remove support for Substrate metadata that is below
    V14 in #1722. Metadata formats below V14 are quite old and we hope this doesn't affect anyone.
  • cargo-contract v5 works only with Rust >= 1.81.

For the linter in cargo-contract the Rust toolchain version changed. To upgrade:

export TOOLCHAIN_VERSION=nightly-2024-09-05
rustup install $TOOLCHAIN_VERSION
rustup component add rust-src --toolchain $TOOLCHAIN_VERSION
rustup run $TOOLCHAIN_VERSION cargo install cargo-dylint dylint-link
