# Changelog

## Version 0.2.0

- Loosened bounds for `UncheckedDowncast` to remove its dependency on `DynDynTarget`
- Remove the unnecessary `B` generic parameter from `UncheckedDowncast`
- Fixed to build properly with newer Nightlies where the `effects` feature is being reworked

- Improved error messages for common mistakes in `dyn_dyn_cast!`

## Version 0.1.0

- Switched numerous methods to taking/returning `DynMetadata<_>` instead of `AnyDynMetadata`
