# Changelog

### v0.9.1
- `Component` should not have to be `Default`, it's builder should be. The `Default` requirement of `Component` has been removed.

### v0.9.0

- Added a declarative syntax macro for defining views.
- Refactored most widgets to be compatible with declarative syntax.
- Fixed some issues with style specifity not being handled correctly.

- Moved some state management responsibility to the caller:
  - Modified `Input` constructor to take a `AsRef<str>` value. It's state no longer has a value of its own.
