This supersedes #1590, but RC coming soon™

Version 4.0.0-beta.1

The coolest feature included in this release is the first first published version of
ink!'s native "end-to-end" (E2E) testing framework.

This enables testing of a contract by deploying and calling it on a Substrate node with
pallet-contracts. See the erc20 example for usage.

Breaking Changes

This release includes a couple of breaking changes.

  1. The CallBuilder::returns() method does not require an extra MessageResult anymore
    as the type is now added under the hood (#1525)
  2. The CallBuilder::invoke() and CreateBuilder::instantiate() methods now unwrap the
    Result from pallet-contracts under the hood (#1602)
    If you wish to handle the error use the new try_ variants of those methods instead.
  3. The CallBuilder::fire() method has been renamed to invoke()
    (#1604)
  4. The returns_result flag has been removed from the #[ink(extension = …)] attribute
    (#1569)
    We now infer this information at compile time. If handle_status is set to true,
    the return type will still be wrapped into Result as before.
  5. The Minimum Supported Rust Version (MSRV) has been set to 1.63.0. This was already
    the case, but previously it was enforced by cargo-contract instead of ink!
    (#1609)
