## [Unreleased]

- Added Python 3.14

## [0.19.0]

### Breaking

- Dropped Python 3.8 & 3.9 to simplify maintenance

### Features

- Added Python 3.13
- Added support for `@as_generator_result` and `@as_async_generator_result`, which function like `@as_result` but wrap the yield values of a generator
- Allow bubbling up unwrapping of nested `Result` inside the `@as_*` decorated classes. If you unwrap an `Err` of an exception type that you handle in the generator, it will return that `Err(Exception)`from the decorated function as if you had thrown the Exception directly.

### Fixes

- Switch to a uv build system with hatch
- Switched linter to Ruff
- Updated the links to point to forked repo
