Release Notes

jonasbb/serde_with (serde_with)

### [`v3.10.0`](https://redirect.github.com/jonasbb/serde_with/releases/tag/v3.10.0): serde_with v3.10.0 [Compare Source](https://redirect.github.com/jonasbb/serde_with/compare/v3.9.0...v3.10.0) ##### Added - Add newline separator by [@​jayvdb](https://redirect.github.com/jayvdb) ([#​777](https://redirect.github.com/jonasbb/serde_with/issues/777)) The `UnixLineSeparator` and `DosLineSeparator` can be used together with `StringWithSeparator`. ##### Fixed - Proper handling of `cfg_attr` in the `serde_as` macro by [@​sivizius](https://redirect.github.com/sivizius) ([#​782](https://redirect.github.com/jonasbb/serde_with/issues/782)) This allows to parse more valid forms of the `cfg_attr` macro, including multiple values and attribute that do not follow the `key = value` schema.
