This is another TinyGo release with many small changes, including over 110 commits.

This release introduces two possible breaking changes:

  1. The machine package has had some changes in the public API, to remove some unintentionally exported constants. It is likely that very little real-world code is affected by this change.

  2. WebAssembly files could previously import functions by leaving a Go function unimplemented, like so:

    func add(a, b int) int

    This worked by accident. With this release, this is no longer possible. Instead, functions will need to be imported explicitly to avoid a compiler error:

    //export add
func add(a, b int) int

    (The //export may be confusing, we intend to add a less-confusing //go:wasm-import directive in the future).

Here is a detailed changelog for this release:
