## Release Notes ## Release Notes
### v1.4.0 (WIP)
* Enhancements for [#71](https://github.com/gulrak/filesystem/issues/71), when compiled with C++20:
* `char8_t` and `std::u8string` are supported where `Source` is the parameter type
* `fs::path::u8string()` and `fs::path::generic_u8string()` now return a `std::u8string`
* The _spaceship operator_ `<=>` is now supported for `fs::path`
* With the define `GHC_FILESYSTEM_ENFORCE_CPP17_API` `ghc::filesystem` will fall back
to the old `fs::path::u8string()` and `fs::path::generic_u8string()` API if preferred
* Bugfix for `fs::proximate(p, ec)` where the internal call to `fs::current_path()` was not
using the `error_code` variant, throwing possible exceptions instead of setting `ec`.
* Some cleanup work to reduce preprocessor directives for better readability and remove unneeded
template specializations.
