###
[`v5.2.1`](https://redirect.github.com/astral-sh/setup-uv/releases/tag/v5.2.1):
🌈 Support toml spec 1.0.0

[Compare
Source](https://redirect.github.com/eifinger/setup-uv/compare/v5.2.0...v5.2.1)

v5.2.0 introduced TOML parsing using
[@&#8203;iarna/toml](https://www.npmjs.com/package/@&#8203;iarna/toml)
because we already found out in `astral-sh/ruff-action` that
[toml](https://www.npmjs.com/package/toml) has missing features.

As it turns out
[@&#8203;iarna/toml](https://www.npmjs.com/package/@&#8203;iarna/toml)
also is not fully TOML spec (1.0.0) compliant.

We now use [smol-toml](https://www.npmjs.com/package/smol-toml)

#### 🐛 Bug fixes

- Support toml spec 1.0.0
