Full Release Notes

### [0.75.0] - 2026-07-29
#### ✨ Highlights

[`pixi publish`](https://pixi.prefix.dev/v0.75.0/build/workspace/#publishing-the-workspace) now publishes every workspace package that opts in in dependency order. It also refuses to publish anything if a necessary source dependencies didn't opt into being published.

```toml title="packages/cpp_math/pixi.toml"
[package]
name = "cpp_math"
publish = true
```

[Offline solves](https://pixi.prefix.dev/v0.75.0/reference/pixi_configuration/#offline) now only consider conda packages you already have, either in the package cache or on a local `file://` channel.

That means that you can run `pixi update --offline` and it will resolve with the packages you have local on your machine.

Completion is now generated from the CLI itself, so environment, platform, feature, and task names complete on every option that takes one, in bash, zsh, fish, and nushell.

As usual we also fixed a couple of bugs.
