+## Construct `IoError` from `std::io::Error` instead of `std::io::ErrorKind`
+
+To give us better control over IO errors, [@cptpiepmatz](https://github.com/cptpiepmatz) changed in [#15777](https://github.com/nushell/nushell/pull/15777) how `IoError`s are created. Now they’re built directly from `std::io::Error` instead of just the `ErrorKind`.
+Just remove the calls to `.kind()` and you're good to go.
