Release 0.5.0

This release adds support for gracefully shutting down command-line
applications through the `Cancellation` concept.

Release 0.4.0 (#176)

This release adds the `Context` struct to commands, provides scaffolding
for new projects and commands in the `clawless-cli`, and prepares the
project for its first public release.

Release 0.3.0 (#120)

This release introduces quite a few quality of life improvements to
Clawless's API:

- Commands can now be documented for users using doc comments
- Commands return a `Result`, which simplifies error handling
- The `app!` macro has been replaced by a simpler `commands!` macro
- `clap` is no re-exported and no longer required as a third-party
  dependency

Please check out the release notes on GitHub for a full list of changes
and links to the relevant pull requests with more information.

dependency to `1.0.86`.

Release 0.1.0 (#17)

The first public release of Clawless introduces the `clawless!`, `app!`,
and `#[command]` macros.
