AI Summary

This release introduces full support for TOML 1.1 multiline syntax and extends the `workspace = true` functionality to environment dependency tables, removing the need for a preview feature. It also includes various bug fixes regarding manifest editing, dependency resolution, and git subprocess handling.

Key Highlights

  • Full support for TOML 1.1 multiline inline tables
  • Support for `workspace = true` in environment dependency tables
  • Commands like `pixi add` now preserve user-written layout
  • Fixed bugs related to dotted keys and name normalization

Breaking Changes

  • Using TOML 1.1 syntax in `pyproject.toml` can break other tools that only read TOML 1.0

New Features

  • TOML 1.1 multiline inline table support
  • Workspace dependency table support

Full Release Notes

### [0.73.0] - 2026-07-15
#### ✨ Highlights

This release brings two big features:
- `workspace = true` now also works in environment `[dependency]` tables
- TOML 1.1 multiline inline tables are now fully supported

As usual we also fixed a couple of bugs.

##### `workspace = true` in environment dependency tables

Until now, `{ workspace = true }` only worked in the package dependency tables and required the `pixi-build` preview.
With this release, the environment tables can inherit from `[workspace.dependencies]` as well, no preview needed.
That means a version shared by several features or targets only has to be declared once:

```toml
[workspace.dependencies]
numpy = "1.*"

[dependencies]
numpy = { workspace = true }

[feature.dev.dependencies]
numpy = { workspace = true }
```

You can learn more about this feature in the docs: https://pixi.prefix.dev/v0.73.0/build/workspace_dependencies/

##### TOML 1.1

Pixi now fully supports [TOML 1.1](https://toml.io/en/v1.1.0).
Most notably, inline tables can now span multiple lines and have trailing commas, which used to be a syntax error:

```toml
[dependencies]
python = {
    version = ">=3.12",
    channel = "conda-forge",
}
```

Commands that modify the manifest, like `pixi add`, keep the layout you wrote.
One word of caution: many other tools only read TOML 1.0 so far, so using the new syntax in `pyproject.toml` can break them even though Pixi accepts it.
