Full Release Notes

## Release Notes

#### ✨ Highlights

There's a new way to include variants in to a pixi workspace! Use
`build-variants-files` to reference external variant definitions from
YAML files.

```toml
[workspace]
build-variants-files = [
    "./pinning/conda_build_config.yaml",
    "./variants/overrides.yaml",
]
```

Read more about this feature in the [docs](https://pixi.sh/dev/reference/pixi_manifest/#build-variants-files-optional).

We deprecated the following syntax in the pixi manifest and give explicit warning when it's used:
- `[project]`: should be replaced by `[workspace]`.
- `[build-dependencies]` and `[host-dependencies]`: should be replaced by `[dependencies]`. 

If you're working on pixi-build backend note that we deprecated build-api v0.

And we also fixed a lot of things!
