## [0.2.0] · 2021-02-01
[0.2.0]: https://github.com/instrumentisto/medea/tree/medea-macro-0.2.0/crates/medea-macro

[Diff](https://github.com/instrumentisto/medea/compare/medea-macro-0.1.0...medea-macro-0.2.0)

### BC Breaks

- `#[dispatchable]` macro:
    - Handler traits now require specifying `Output` associative type, which is the return type of all handler trait methods ([#66]).

### Added

- `#[derive(JsCaused)]` macro for deriving `JsCaused` trait from `medea-jason` crate ([#68]).
- `#[dispatchable]` macro:
    - Optional argument to specify `self` type for methods of `*Handler` trait (e.g. `#[dispatchable(self: &Self)]`) ([#112]);
    - Optional argument that enables [`async-trait`] integration (e.g. `#[dispatchable(async_trait(?Send))]`) ([#112]).
- `#[watchers]` macro for generating `Component::spawn` method in `medea-jason` crate ([#169]).

### Fixed

- `#[enum_delegate]` macro now works fine on functions with multiple arguments ([#91]);
- `#[dispatchable]` handler trait visibility now corresponds to original enum visibility ([#147]).
