## Unreleased
## [0.10.1] - 2025-04-08
### API Changes
- Add `ron::Options::to_io_writer` and `ron::Options::to_io_writer_pretty` to allow writing into an `io::Writer` ([#561](https://github.com/ron-rs/ron/pull/561))
- Breaking: `ron::value::Number` is now non-exhaustive, to avoid breaking `match`es when feature unification enables more of its variants than expected ([#564](https://github.com/ron-rs/ron/pull/564))
## [0.9.0] - 2025-03-18
### API Changes
- Add `ron::value::RawValue` helper type which can (de)serialize any valid RON ([#407](https://github.com/ron-rs/ron/pull/407))

- Add new path-based field metadata serialization support via `PrettyConfig` ([#544](https://github.com/ron-rs/ron/pull/544))
