chore: bump version to v0.71.0

[Hofer-Julian]

[0.71.0] - 2026-06-24

✨ Highlights

This release adds a lot of exciting features!

The biggest one is that we deprecated [system-requirements] in favor of the much more expressive rich platform support.
On top of operating systems and processor architecture, platforms can now also include system requirements like CUDA or glibc version:

[workspace]
platforms = [
  "osx-arm64",
  { platform = "linux-64", cuda = "12.0", glibc = "2.28" },
  { name = "jetson-nano", platform = "linux-aarch64", cuda = "12.8" },
]

Speaking of CUDA, together with rich platforms we added support for __cuda_arch.
We already supported __cuda which allows specifying the driver version you require.
With __cuda_arch, you can specify the necessary hardware architecture.

We also added support for v3 repodata.
That means you can declare extra dependency groups:

[package.extra-dependencies.test]
hypothesis = "*"
pytest = ">=8"

[package.extra-dependencies.cuda]
cupy = ">=13"

And of course you can also consume them:

[dependencies]
mypackage = { path = "./mypackage", extras = ["test"] }

It also includes the when keyword:

[package.run-dependencies]
unix-helper = { version = "*", when = "__unix" }

And it allows to set flags:

[package.build]
backend = { name = "pixi-build-cmake", version = "0.*" }
# not required:
channels = ["https://prefix.dev/conda-forge"]
config = { key = "value" } # Optional configuration, specific to the build backend
flags = [
  "cuda",
  "blas_openblas",
] # Optional variant flags recorded in the package metadata

Finally, we revamped the way we define conditional dependencies.
We deprecated [target.*.host,build,run-dependencies] and introduce the following syntax:

# Only needed when cross-compiling (host platform differs from build platform).
[package.build-dependencies."if(host_platform != build_platform)"]
cross-python = "*"

# Only on Linux.
[package.host-dependencies."if(host_platform == 'linux-64')"]
libgl-devel = ">=1.7.0,<2"

# Based on a build variant.
[package.host-dependencies."if(matches(python, '>=3.10'))"]
exceptiongroup = "*"

NOTE: This only affects source dependencies. [target.*.dependencies] remains valid.
