## 0.5.3

This release includes support for conflicting optional dependencies and dependency groups in the uv resolver, including the ability to specify dependency sources (like index assignment) on a per-extra or per-group basis.

For example, you can now select CPU-only vs. GPU-enabled PyTorch builds at runtime by defining conflicting extras in a `pyproject.toml`, and assigning different extras to different PyTorch indexes:

```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12.0"

[project.optional-dependencies]
# Include `torch` whenever `--extra cpu` or `--extra gpu` is provided.
cpu = ["torch>=2.5.1"]
gpu = ["torch>=2.5.1"]

[tool.uv]
# But allow `cpu` and `gpu` to choose conflicting versions of `torch`.
conflicts = [[{ extra = "cpu" }, { extra = "gpu" }]]

[tool.uv.sources]
torch = [
  # With `--extra cpu`, pull PyTorch from the CPU-only index.
  { index = "pytorch-cpu", extra = "cpu", marker = "platform_system != 'Darwin'" },
  # With `--extra gpu`, pull PyTorch from the GPU-enabled index.
  { index = "pytorch-gpu", extra = "gpu" },
]

[[tool.uv.index]]
name = "pytorch-cpu"
url = "https://download.pytorch.org/whl/cpu"
explicit = true

[[tool.uv.index]]
name = "pytorch-gpu"
url = "https://download.pytorch.org/whl/cu124"
explicit = true
```

## 0.5.0

Since the launch of Python version, project, and tool management capabilities back in August, we've seen extraordinary adoption of uv. We've been iterating rapidly: adding new features, fixing bugs, and improving the user experience. Despite moving quickly, stability and compatibility have been a major focus — we've made thirty releases since our last breaking change. Consequently, we've accumulated various changes that improve correctness and user experience, but could break some workflows. This release contains those changes; many have been marked as breaking out of an abundance of caution. We expect most users to be able to upgrade without making changes.

### Breaking

- **Use base executable to set virtualenv Python path** ([#8481](https://github.com/astral-sh/uv/pull/8481))
  
  Previously, uv canonicalized the path to the Python executable when setting the Python path in created virtual environments. This behavior had several undesirable effects: it would bypass stabilized version directories (as constructed by Homebrew) and it was not consistent with the Python standard library's behavior. Now, uv uses the `sys._base_executable` path.
- **Use XDG (i.e. `~/.local/bin`) instead of the Cargo home directory in the installer** ([#8420](https://github.com/astral-sh/uv/pull/8420))
  
  Previously, uv's installer used `$CARGO_HOME` or `~/.cargo/bin` for its target install directory. It's been a longstanding complaint that uv uses this directory, as there's no relationship to Cargo. Now, uv will be installed into `$XDG_BIN_HOME`, `$XDG_DATA_HOME/../bin`, or `~/.local/bin` (in that order). Note that `$UV_INSTALL_DIR` can always be used to override the target directory.
- **Discover and respect `.python-version` files in parent directories** ([#6370](https://github.com/astral-sh/uv/pull/6370))
  
  Previously, uv only read `.python-version` files from the working directory. Now, uv will check parent directories for `.python-version` files; however uv will not search for `.python-version` files beyond project boundaries. The new behavior is better aligned with that of `pyenv` and Rye.
- **Error when disallowed settings are defined in `uv.toml`** ([#8550](https://github.com/astral-sh/uv/pull/8550))
  
  Some settings can only be defined in the `pyproject.toml`. Previously, uv would ignore these settings when present in the `uv.toml`. Now, uv will error to avoid confusion about why the settings are not respected.
- **Implement PEP 440-compliant local version semantics** ([#8797](https://github.com/astral-sh/uv/pull/8797))
  
  Previously, uv's implementation of local versions (e.g. `2.0+cpu`) was not compliant with the specification due to the technical complexity of implementing the local version semantics in the PubGrub algorithm. Thanks to the work of @ericmarkmartin, uv now has a spec-compliant implementation. Namely, uv will now allow a request for `torch==2.1.0` to install `torch@2.1.0+cpu` regardless of whether `torch@2.1.0` (without a local tag) actually exists.
- **Treat the base Conda environment as a system environment** ([#7691](https://github.com/astral-sh/uv/pull/7691))
  
  Previously, uv would not distinguish between the base and other Conda environments. Now, uv uses `CONDA_DEFAULT_ENV` and the names `base` and `default` to determine if an environment active via `CONDA_PREFIX` is the base environment. If the base environment is active, the `--system` flag must be used to mutate it.
- **Do not allow pre-releases when the `!=` operator is used** ([#7974](https://github.com/astral-sh/uv/pull/7974))
  
  Previously, uv would use the presence of a pre-release specifier in a version specifier as an opt-in to allow pre-release versions during resolution. The new behavior does not allow pre-releases when an inequals operator is used, e.g., `!= 2.0a1`.
- **Prefer `USERPROFILE` over `FOLDERID_Profile` when selecting a home directory on Windows** ([#8048](https://github.com/astral-sh/uv/pull/8048))
  
  This change is a side-effect of switching from the `directories` crate to `etcetera` for determining canonical system paths. If `USERPROFILE` is not set, the behavior will be unchanged.
- **Improve interactions between color environment variables and CLI options** ([#8215](https://github.com/astral-sh/uv/pull/8215))
  
  Previously, uv would respect the `FORCE_COLOR` and `NO_COLOR` environment variables over the `--color` flag. Now, when the `--color` flag is explicitly provided, uv will respect it over the environment variables.
- **Make `allow-insecure-host` a global option** ([#8476](https://github.com/astral-sh/uv/pull/8476))
  
  Previously, this option was only available in some parts of uv. Now, `--allow-insecure-host` can be provided to any command. For consistency, the `allow-insecure-host` setting has been removed from the `[tool.uv.pip]` configuration in favor of `[tool.uv]`.
- **Only write `.python-version` files during `uv init` for workspace members if the version differs** ([#8897](https://github.com/astral-sh/uv/pull/8897))
  
  Previously, uv would create a `.python-version` file for workspace members during `uv init`. Now, uv will only do so if the version differs from the `.python-version` file in the workspace root since uv will respect `.python-version` files in parent directories.

## 0.4.27

This release includes support for the `[dependency-groups]` table as recently standardized in [PEP 735](https://peps.python.org/pep-0735/). The table allows for declaration of optional dependency groups that are not published as part of the package metadata, unlike `[project.optional-dependencies]`. There are new `--group`, `--only-group`, and `--no-group` options throughout the uv interface.

Previously, uv used a single `tool.uv.dev-dependencies` list for declaration of development dependencies. Now, uv supports declaring development dependencies in a standardized format and allows splitting development dependencies into multiple groups.

For compatibility, and to simplify usage for people that do not need multiple groups, uv special-cases the group named `dev`. The `dev` group is equivalent to `tool.uv.dev-dependencies`. The contents of `tool.uv.dev-dependencies` will merged into the `dev` group in uv's resolver. The `--dev`, `--only-dev`, and `--no-dev` flags remain as aliases for the corresponding `--group` options. Support for `tool.uv.dev-dependencies` remains in this release, but will display warnings in a future release.

uv syncs the `dev` group by default — this matches the existing behavior for `tool.uv.dev-dependencies`. The default groups can be changed with the `tool.uv.default-groups` setting.

Thank you to Stephen Rosen who authored PEP 735.

## 0.4.23

This release introduces a revamped system for defining package indexes, as an alternative to the existing pip-style
`--index-url` and `--extra-index-url` configuration options.

You can now define named indexes in your `pyproject.toml` file using the `[[tool.uv.index]]` table:

```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cpu"
```

Packages can be pinned to a specific index via `tool.uv.sources`, to ensure that a given package is installed from the
correct index. For example, to ensure that `torch` is *always* installed from the `pytorch` index:

```toml
[tool.uv.sources]
torch = { index = "pytorch" }

[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cpu"
```

Indexes can also be marked as `explicit = true` to prevent packages from being installed from that index
unless explicitly pinned. For example, to ensure that `torch` is installed from the `pytorch` index, but all other
packages are installed from the default index:

```toml
[tool.uv.sources]
torch = { index = "pytorch" }

[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cpu"
explicit = true
```

To define an additional index outside a `pyproject.toml` file, use the `--index` command-line argument
(or the `UV_INDEX` environment variable); to replace the default index (PyPI), use the `--default-index` command-line
argument (or `UV_DEFAULT_INDEX`).

These changes are entirely backwards-compatible with the deprecated `--index-url` and `--extra-index-url` options,
which continue to work as before.

See the [Index](https://docs.astral.sh/uv/configuration/indexes/) documentation for more.

### Other changes

## 0.4.0

This release adds first-class support for Python projects that are not designed as Python packages (e.g., web applications, data science projects, etc.).

In doing so, it includes some breaking changes around uv's handling of projects. Previously, uv required that all projects could be built into distributable Python packages, and installed them into the virtual environment. Projects created by `uv init` always included a `[build-system]` definition and existing projects that did not define a `[build-system]` would use the legacy setuptools build backend by default.

Most users are not developing libraries that need to be packaged and published to PyPI. Instead, they're building applications using web frameworks, or running collections of Python scripts in the project's root directory. In these cases, requiring a `[build-system]` was confusing and error-prone. In this release, uv changes the default behavior to orient around these common use cases.

In summary, the major changes are:

- uv no longer attempts to package and install projects that do not define a `[build-system]`.
  - While the project itself will not be installed into the virtual environment, its dependencies will still be included.
  - The previous behavior can be recovered by setting `package = true` in the `[tool.uv]` section of your `pyproject.toml`.
- `uv init` no longer creates a `src/` directory or defines a `[build-system]` by default.
  - The previous behavior can be recovered with `uv init --lib` or `uv init --app --package`.
- uv allows and recommends including `[project]` definitions in virtual workspace roots.
  - Previously, the uv required the `[project]` section to be omitted.
- uv allows disabling packaging of projects, even if they define a `[build-system]`, by setting `package = false` in the `[tool.uv]` section of your `pyproject.toml`.

See the latest documentation on [build systems in projects](http://docs.astral.sh/uv/concepts/projects/#build-systems) for more details.

## 0.3.0

This release introduces the uv [project](https://docs.astral.sh/uv/guides/projects/),
[tool](https://docs.astral.sh/uv/guides/tools/),
[script](https://docs.astral.sh/uv/guides/scripts/), and
[python](https://docs.astral.sh/uv/guides/install-python/) interfaces. If you've been following
uv's development, you've probably seen these new commands behind a preview flag. Now, the
interfaces are stable and ready for production-use.

These features are all documented in [new, comprehensive
documentation](https://docs.astral.sh/uv/).

This release also stabilizes preview functionality in `uv venv`:

- `uv venv --python <version>` will [automatically
download](https://docs.astral.sh/uv/concepts/python-versions/#requesting-a-version) the Python
version if required
- `uv venv` will read the required Python version from the `.python-version` file or
`pyproject.toml`

The `uv pip` interface should not be affected by any breaking changes.

Note the following changelog entries does not include all the new features since they were added
incrementally as preview features. See the
[feature page](https://docs.astral.sh/uv/getting-started/features/) in the documentation for a
comprehensive listing, or read the [blog post](https://astral.sh/blog/uv-unified-python-packaging)
for more context on the new features.

## 0.2.0

Starting with this release, uv will use the **minor** version tag to indicate breaking changes.

### Breaking

In this release, discovery of Python interpreters has changed. These changes should have a limited effect in most
use-cases, however, it has been marked as a breaking change because the interpreter used by uv could change in
some edge cases.

When multiple Python interpreters are installed, uv makes an attempt to find the exact version you requested.
Previously, uv would stop at the first Python interpreter it discovered — if the interpreter did not satisfy
the requested version, uv would fail. Now, uv will query multiple Python interpreters until it finds the
requested version, skipping interpreters that are broken or do not satisfy the request.

Additionally, uv now allows requests for interpreter implementations such as `pypy` and `cpython`. For example,
the request `--python cpython` will ignore a `python` executable that's implemented by `pypy`. These requests may
also include a version, e.g., `--python pypy@3.10`. By default, uv will accept *any* interpreter implementation.

In summary, the following Python interpreter requests are now allowed:

- A Python version without an implementation name, e.g., `3.10`
- A path to a directory containing a Python installation, e.g., `./foo/.venv`
- A path to a Python executable, e.g., `~/bin/python`
- A Python implementation without a version, e.g., `pypy` or `cpython`
- A Python implementation name and version, e.g., `pypy3.8` or `pypy@3.8`
- The name of a Python executable (for lookup in the `PATH`), e.g., `foopython3`

Previously, interpreter requests that were not versions or paths were always treated as executable
names.

To align the user expectations, uv now respects the interpreter that starts it. For example, `python -m uv ...` will
now prefer the `python` interpreter that was used to start uv instead of searching for a virtual environment.

We now check if discovered interpreters are virtual environments. This means that setting `VIRTUAL_ENV` to a Python
installation directory that is *not* a virtual environment will no longer work. Instead, use `--system`
or `--python <path>`
to request the interpreter.

## 0.1.33

### Breaking changes

Using the keyring requires a username to be provided on index URLs now. Previously, the username `oauth2accesstoken`
was assumed. This will affect Google Artifact Registry users using `--keyring-provider subprocess` and an index URL
without a username. The suggested fix is to add the required username to index URLs,
e.g., `https://oauth2accesstoken@<url>`.
