### Release Notes

<details>
<summary>sindresorhus/execa (execa)</summary>

###
[`v9.4.0`](https://redirect.github.com/sindresorhus/execa/releases/tag/v9.4.0)

[Compare
Source](https://redirect.github.com/sindresorhus/execa/compare/v9.3.1...v9.4.0)

#### Features

- We've created a separate package called
[nano-spawn](https://redirect.github.com/sindresorhus/nano-spawn). It is
similar to Execa but with fewer features, for a much smaller package
size. [More
info.](https://redirect.github.com/sindresorhus/execa/blob/main/docs/small.md)

#### Bug fixes

- Both
[`execaNode()`](https://redirect.github.com/sindresorhus/execa/blob/main/docs/node.md)
and the
[`preferLocal`](https://redirect.github.com/sindresorhus/execa/blob/main/docs/environment.md#local-binaries)
option modify the `PATH` environment variable. This release includes
some minor improvements to ensure that environment variable remains
small
([https://github.com/sindresorhus/npm-run-path/pull/20](https://redirect.github.com/sindresorhus/npm-run-path/pull/20)).
It also handles a few related edge cases better
([https://github.com/sindresorhus/npm-run-path/pull/21](https://redirect.github.com/sindresorhus/npm-run-path/pull/21)).

#### Documentation

- Small documentation typo fix, thanks
