### Release Notes

[`v1.6.0`](https://redirect.github.com/BurntSushi/toml/releases/tag/v1.6.0)

[Compare
Source](https://redirect.github.com/BurntSushi/toml/compare/v1.5.0...v1.6.0)

TOML 1.1 is now enabled by default. The TOML changelog has an overview
of changes: <https://github.com/toml-lang/toml/blob/main/CHANGELOG.md>

Also two small fixes:

- Encode large floats as exponent syntax so that round-tripping things
like `5e+22` is correct.

- Using duplicate array keys would not give an error:

  ```
  arr = [1]
  arr = [2]
  ```

This will now correctly give a "Key 'arr' has already been defined"
error.

</details>
