v0.77.0

[0.77.0] - 2026-08-18

✨ Highlights

This release includes the API update for the backends such that we support pin-compatible and pin-subpackage specs in package manifests. For example:

# Pin subpackage `mypkg` to the same version as the package itself, but allow any compatible version of `mypkg` to be used.
[package]
name = "mypkg"

[package.run-exports.weak]
mypkg = { pin-subpackage = { upper-bound = "x.x" } }

# Pin `boltons` to a compatible version.
[package.host-dependencies]
boltons = ">=2,<3"

[package.run-dependencies]
boltons = { pin-compatible = true }

Note that this is a pixi-build-api-version update to v7.

Also, you can now modify the workspace activation with the new pixi workspace activation subcommand.

v0.76.0

[0.76.0] - 2026-08-03

✨ Highlights

A single Python file can now carry its own environment. Pixi reads PEP 723 inline metadata, and --script works on init, run, add, remove, lock, list, tree, and workspace export.

# /// script
# requires-python = ">=3.11"
# dependencies = ["rich>=13.9.2"]
# ///
import rich

rich.print("Hi from [bold magenta]hello.py[/bold magenta]!")

pixi run --script hello.py is the whole setup: no pixi.toml, no .pixi folder, and no lock file unless you ask for one with pixi lock --script.

PEP 723 only covers Python and PyPI, so Pixi reads tool.pixi for the rest. This greatly extends the script's capabilities, for example to add conda dependencies:

# /// script
# dependencies = ["httpx"]
# [tool.pixi.workspace]
# channels = ["conda-forge"]
# [tool.pixi.dependencies]
# gdal = "*"
# ///

pixi init --script, pixi add --script <file> gdal, and pixi add --script <file> --pypi httpx write that block for you. Scripts don't have to be local either: pixi run --script takes a URL, a Gist page (that one builds CPython 3.16 from git first), or - to read from stdin.

Thanks @manzt for building this out across five PRs, see the standalone scripts docs for the rest. This release also adds [package.run-exports], an lfs field for git dependencies, and configurable channel priority.

Added

• Support PEP 723 scripts with --script by @manzt in #6648
• Support PEP 723 scripts in pixi list by @manzt in #6726
• Support [package.run-exports] in package manifests by @Hofer-Julian in #6696
• Run PEP 723 scripts from URLs by @manzt in #6728
• Resolve GitHub Gist scripts by @manzt in #6739
• Run PEP 723 scripts from standard input by @manzt in #6740
• Update rattler and support flexible channel priority by @Hofer-Julian in #6743
• Add lfs field to git dependencies by @Hofer-Julian in #6744

Changed

• Point the uv cache at the pixi cache directory by @wolfv in #6712
• Resolve the target subdir to the declared workspace platform by @wolfv in #6715
• Strip ANSI escapes from rendered diagnostics in snapshots by @ruben-arts in #6735

• Fix pre-commit during backends release script by @lucascolley in #6719

New Contributors

• @manzt made their first contribution in #6740

v0.75.0

[0.75.0] - 2026-07-29

✨ Highlights

pixi publish 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.

[package]
name = "cpp_math"
publish = true

Offline solves 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.

Added

• Publish the workspace packages that opt in by @Hofer-Julian in #6526
• Rework completion by @hunger in #6686
• Restrict offline solves to locally available packages by @Hofer-Julian in #6644
• Validate __archspec microarchitecture names by @hunger in #6701

Changed

• Report the assumed platform per environment by @hunger in #6508
• Reuse cached artifacts for immutable sources when the cache dir is gone by @Hofer-Julian in #6699

Documentation

• Explain that $PREFIX is not expanded on Windows by @baszalmstra in #6690

Fixed

• Clean stale files from incremental ROS Python builds by @baszalmstra in #6691
• Fix CI on main and slim down extra slow tests by @Hofer-Julian in #6708

Removed

• Remove stray insta snapshot artifact by @hunger in #6683

v0.74.0

[0.74.0] - 2026-07-27

✨ Highlights

Environments can now define content inline, no feature needed:

[environments.test.dependencies]
pytest = "*"

[environments.test-lower-bounds]
solve-strategy = "lowest-direct"

And pixi global can build tools from sources without a package manifest, just name the backend:

pixi global install --git https://github.com/BurntSushi/xsv.git --build-backend pixi-build-rust

We also fixed a bunch of bugs.

Added

• Inline environments by @Hofer-Julian in #6497
• Add offline mode (--offline) by @baszalmstra in #6608
• Inline package manifests for pixi global by @Hofer-Julian in #6521

• Keep PR docs builds out of the deploy concurrency group by @Hofer-Julian in #6631

Documentation

• Name the failing environment in pixi global error messages by @tdejager in #6643
• Rename --subdir to --subdirectory for git dependencies by @Hofer-Julian in #6657
• Only source declarations decide inline package suppression by @Hofer-Julian in #6662
• Name the package when solving build environments fails by @Hofer-Julian in #6667
• Give inline packages a name and a helpful error for Cargo workspaces by @Hofer-Julian in #6659

v0.73.0

[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:

[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.
Most notably, inline tables can now span multiple lines and have trailing commas, which used to be a syntax error:

[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.

Added

• Support workspace = true in environment dependency tables by @Hofer-Julian in #6592
• Full support for TOML 1.1 by @Hofer-Julian in #6500

Changed

• Complete tasks after options in pixi run by @hunger in #6518

Documentation

• Expand docs for extras, flags, and conditional dependencies by @wolfv in #6570
• Document TOML 1.1 support by @Hofer-Julian
• Fix python version constraint location in pixi-build-python backend by @hunger in #6580

Fixed

• Handle dotted keys, regular tables and name normalization when editing manifests by @Hofer-Julian
• Isolate global_specs tests from the user's global manifest by @Hofer-Julian in #6573
• Mark slow integration tests with pytest.mark.slow by @Hofer-Julian in #6574
• Fail on git subprocess errors so a rev can resolve to a tag by @Hofer-Julian in #6591
• Resolve workspace dependencies in inline package definitions by @Hofer-Julian in #6590
• Do not chain run-exports when resolving source package run deps by @Hofer-Julian in #6587
• Anchor CARGO_TARGET_DIR to the workspace root by @Hofer-Julian in #6602

v0.72.0

[0.72.0] - 2026-07-01

✨ Highlights

This release brings an exciting new Pixi Build feature: inline package manifests.
If you want to build a package from source that didn't contain a Pixi Build manifest, that used to be pretty annoying.
Now you can simply set the metadata inline like this:

[dependencies]
rust-package = { git = "https://github.com/user/repo.git", package.build.backend.name = "pixi-build-rust" }

You can learn more about this feature in the docs: https://pixi.prefix.dev/v0.72.0/build/inline_packages/

Added

• Inline package definition by @Hofer-Julian in #6428
