Release Notes

BurntSushi/toml

### [`v1.3.1`](https://togithub.com/BurntSushi/toml/releases/tag/v1.3.1) [Compare Source](https://togithub.com/BurntSushi/toml/compare/v1.3.0...v1.3.1) This fixes two small bugs: - The `BURNTSUSHI_TOML_110` environment variable would be checked on package import, rather than Decode(). This meant that setting `os.Setenv("BURNTSUSHI_TOML_110", "")` had no effect, as it happens after the import. - Fix order of `Meta.Keys()` for inline tables (this has been an issue since support for inline tables was added).
