v0.7.0

⚠️ Breaking changes ⚠️

There are two breaking changes in this release.

1. cargo-component-bindings removed

This breaking change requires manual intervention for existing cargo-component projects to get those projects to build with this release.

cargo-component-bindings has been removed as a dependency; bindings are now directly generated into a src/bindings.rs submodule by cargo-component with no macro involved.

Existing cargo-component projects can be fixed with the following steps:

1. Install the latest cargo-component.

   With the removal of the upgrade subcommand (see below), the latest version of cargo-component can be installed with either cargo install cargo-component or cargo binstall cargo-component (requires cargo-binstall).

2. Edit Cargo.toml:

   Replace the existing cargo-component-bindings dependency with:

   wit-bindgen = { version = "0.16.0", default-features = false, features = ["realloc"] }

   This makes the wit-bindgen runtime functions / types available to the generated code (but does not make the wit-bindgen::generate! macro available).

3. Edit src/main.rs or src/lib.rs:

   Depending on the whether the project is a command (src/main.rs) or a library (src/lib.rs), edit the file to replace the cargo_component_bindings::generate! macro invocation with:

   mod bindings;

2. cargo component update subcommand removed.

With the removal of the cargo-component-bindings crate, the subcommand became a less-functional wrapper around cargo install.

To update cargo-component in the future, use cargo install cargo-component or cargo binstall cargo-component (requires cargo-binstall).
