 # Changelog
 
+## 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.
+
+### Enhancements
+
+- Add index URLs when provided via `uv add --index` or `--default-index` ([#7746](https://github.com/astral-sh/uv/pull/7746))
+- Add support for named and explicit indexes ([#7481](https://github.com/astral-sh/uv/pull/7481))
+- Add templates for popular build backends ([#7857](https://github.com/astral-sh/uv/pull/7857))
+- Allow multiple pinned indexes in `tool.uv.sources` ([#7769](https://github.com/astral-sh/uv/pull/7769))
+- Allow users to incorporate Git tags into dynamic cache keys ([#8259](https://github.com/astral-sh/uv/pull/8259))
+- Pin named indexes in `uv add` ([#7747](https://github.com/astral-sh/uv/pull/7747))
+- Respect named `--index` and `--default-index` values in `tool.uv.sources` ([#7910](https://github.com/astral-sh/uv/pull/7910))
+- Update to latest PubGrub version ([#8245](https://github.com/astral-sh/uv/pull/8245))
+- Enable environment variable authentication for named indexes ([#7741](https://github.com/astral-sh/uv/pull/7741))
+- Avoid showing lower-bound warning outside of explicit lock and sync ([#8234](https://github.com/astral-sh/uv/pull/8234))
+- Improve logging during lock errors ([#8258](https://github.com/astral-sh/uv/pull/8258))
+- Improve styling of `requires-python` warnings ([#8240](https://github.com/astral-sh/uv/pull/8240))
+- Show hint in resolution failure on `Forbidden` (`403`) or `Unauthorized` (`401`) ([#8264](https://github.com/astral-sh/uv/pull/8264))
+- Update to latest `cargo-dist` version (includes new installer features) ([#8270](https://github.com/astral-sh/uv/pull/8270))
+- Warn when patch version in `requires-python` is implicitly `0` ([#7959](https://github.com/astral-sh/uv/pull/7959))
+- Add more context on client errors during range requests ([#8285](https://github.com/astral-sh/uv/pull/8285))
+
+### Bug fixes

 The storage directory can be configured with `UV_PYTHON_INSTALL_DIR`.
 
+### Snapshot testing
+
+uv uses [insta](https://insta.rs/) for snapshot testing. It's recommended (but not necessary) to use
+`cargo-insta` for a better snapshot review experience. See the
+[installation guide](https://insta.rs/docs/cli/) for more information.
+
+In tests, you can use `uv_snapshot!` macro to simplify creating snapshots for uv commands. For
+example:
+
+```rust
+#[test]
+fn test_add() {
+    let context = TestContext::new("3.12");
+    uv_snapshot!(context.filters(), context.add().arg("requests"), @"");
+}
+```
+
+To run and review a specific snapshot test:
+
+```shell
+cargo test --package <package> --test <test> -- <test_name> -- --exact
+cargo insta review
+```
+
 ### Local testing
 
 You can invoke your development version of uv with `cargo run -- <args>`. For example:
diff --git a/Cargo.lock b/Cargo.lock
index e0add76a3..aea58177e 100644

+/// >   containing only the verbatim matched characters MUST be supported.
+/// >   Within `[...]`, the hyphen indicates a range (e.g. `a-z`).
+/// >   Hyphens at the start or end are matched literally.
+/// >
+/// > - Path delimiters MUST be the forward slash character (`/`).
+/// >   Patterns are relative to the directory containing `pyproject.toml`,
+/// >   therefore the leading slash character MUST NOT be used.
+/// >
+/// > - Parent directory indicators (`..`) MUST NOT be used.

+## Build dependencies
+
+If a project is structured as [Python package](./projects.md#build-systems), it may declare
+dependencies that are required to build the project, but not required to run it. These dependencies
+are specified in the `[build-system]` table under `build-system.requires`, following
+[PEP 518](https://peps.python.org/pep-0518/).
+
+For example, if a project uses `setuptools` as its build backend, it should declare `setuptools` as
+a build dependency:
+
+```toml title="pyproject.toml"
+[project]
+name = "pandas"
+version = "0.1.0"
+
+[build-system]
+requires = ["setuptools>=42"]
+build-backend = "setuptools.build_meta"
+```
+
+By default, uv will respect `tool.uv.sources` when resolving build dependencies. For example, to use
+a local version of `setuptools` for building, add the source to `tool.uv.sources`:
+
+```toml title="pyproject.toml"
+[project]
+name = "pandas"
+version = "0.1.0"
+
+[build-system]
+requires = ["setuptools>=42"]
+build-backend = "setuptools.build_meta"
+
+[tool.uv.sources]
+setuptools = { path = "./packages/setuptools" }
+```
+
+When publishing a package, we recommend running `uv build --no-sources` to ensure that the package
+builds correctly when `tool.uv.sources` is disabled, as is the case when using other build tools,
+like [`pypa/build`](https://github.com/pypa/build).
+
+## Editable dependencies
+
+A regular installation of a directory with a Python package first builds a wheel and then installs
+that wheel into your virtual environment, copying all source files. When the package source files
+are edited, the virtual environment will contain outdated versions.
+
+Editable installations solve this problem by adding a link to the project within the virtual
+environment (a `.pth` file), which instructs the interpreter to include the source files directly.
+
+There are some limitations to editables (mainly: the build backend needs to support them, and native
+modules aren't recompiled before import), but they are useful for development, as the virtual
+environment will always use the latest changes to the package.
+
+uv uses editable installation for workspace packages by default.
+
+To add an editable dependency, use the `--editable` flag:
+
+```console
+$ uv add --editable ./path/foo
+```
+
+Or, to opt-out of using an editable dependency in a workspace:
+
+```console
+$ uv add --no-editable ./path/foo
+```
+

-## Editable dependencies
-
-A regular installation of a directory with a Python package first builds a wheel and then installs
-that wheel into your virtual environment, copying all source files. When the package source files
-are edited, the virtual environment will contain outdated versions.
-
-Editable installations solve this problem by adding a link to the project within the virtual
-environment (a `.pth` file), which instructs the interpreter to include the source files directly.
-
-There are some limitations to editables (mainly: the build backend needs to support them, and native
-modules aren't recompiled before import), but they are useful for development, as the virtual
-environment will always use the latest changes to the package.
-
-uv uses editable installation for workspace packages by default.
-
-To add an editable dependency, use the `--editable` flag:
-
-```console
-$ uv add --editable ./path/foo

-
-Or, to opt-out of using an editable dependency in a workspace:

-$ uv add --no-editable ./path/foo

+# Package indexes
+
+By default, uv uses the [Python Package Index (PyPI)](https://pypi.org) for dependency resolution
+and package installation. However, uv can be configured to use other package indexes, including
+private indexes, via the `[[tool.uv.index]]` configuration option (and `--index`, the analogous
+command-line option).
+
+## Defining an index
+
+To include an additional index when resolving dependencies, add a `[[tool.uv.index]]` entry to your
+`pyproject.toml`:
+
+```toml
+[[tool.uv.index]]
+# Optional name for the index.
+name = "pytorch"
+# Required URL for the index.
+url = "https://download.pytorch.org/whl/cpu"
+```
+
+Indexes are prioritized in the order in which they’re defined, such that the first index listed in
+the configuration file is the first index consulted when resolving dependencies, with indexes
+provided via the command line taking precedence over those in the configuration file.
+
+By default, uv includes the Python Package Index (PyPI) as the "default" index, i.e., the index used
+when a package is not found on any other index. To exclude PyPI from the list of indexes, set
+`default = true` on another index entry (or use the `--default-index` command-line option):
+
+```toml
+[[tool.uv.index]]
+name = "pytorch"
+url = "https://download.pytorch.org/whl/cpu"
+default = true
+```
+
+The default index is always treated as lowest priority, regardless of its position in the list of
+indexes.
+
+## Pinning a package to an index
+
+A package can be pinned to a specific index by specifying the index in its `tool.uv.sources` entry.
+For example, to ensure that `torch` is _always_ installed from the `pytorch` index, add the
+following to your `pyproject.toml`:
+
+```toml
+[tool.uv.sources]
+torch = { index = "pytorch" }
+
+[[tool.uv.index]]
+name = "pytorch"
+url = "https://download.pytorch.org/whl/cpu"
+```
+
+Similarly, to pull from a different index based on the platform, you can provide a list of sources
+disambiguated by environment markers:
+
+```toml title="pyproject.toml"
+[project]
+dependencies = ["pytorch"]
+
+[tool.uv.sources]
+pytorch = [
+  { index = "torch-cu118", marker = "sys_platform == 'darwin'"},
+  { index = "torch-cu124", marker = "sys_platform != 'darwin'"},
+]
+
+[[tool.uv.index]]
+name = "torch-cu118"
+url = "https://download.pytorch.org/whl/cu118"
+
+[[tool.uv.index]]
+name = "torch-cu124"
+url = "https://download.pytorch.org/whl/cu124"
+```
+
+An index can be marked as `explicit = true` to prevent packages from being installed from that index
+unless explicitly pinned to it. For example, to ensure that `torch` is installed from the `pytorch`
+index, but all other packages are installed from PyPI, add the following to your `pyproject.toml`:
+
+```toml
+[tool.uv.sources]
+torch = { index = "pytorch" }
+
+[[tool.uv.index]]
+name = "pytorch"
+url = "https://download.pytorch.org/whl/cpu"
+explicit = true
+```
+
+Named indexes referenced via `tool.uv.sources` must be defined within the project's `pyproject.toml`
+file; indexes provided via the command-line, environment variables, or user-level configuration will
+not be recognized.
+
+## Searching across multiple indexes
+
+By default, uv will stop at the first index on which a given package is available, and limit
+resolutions to those present on that first index (`first-match`).
+
+For example, if an internal index is specified via `[[tool.uv.index]]`, uv's behavior is such that
+if a package exists on that internal index, it will _always_ be installed from that internal index,
+and never from PyPI. The intent is to prevent "dependency confusion" attacks, in which an attacker
+publishes a malicious package on PyPI with the same name as an internal package, thus causing the
+malicious package to be installed instead of the internal package. See, for example,
+[the `torchtriton` attack](https://pytorch.org/blog/compromised-nightly-dependency/) from
+December 2022.
+
+Users can opt in to alternate index behaviors via the`--index-strategy` command-line option, or the
+`UV_INDEX_STRATEGY` environment variable, which supports the following values:
+
+- `first-match` (default): Search for each package across all indexes, limiting the candidate
+  versions to those present in the first index that contains the package.
+- `unsafe-first-match`: Search for each package across all indexes, but prefer the first index with
+  a compatible version, even if newer versions are available on other indexes.
+- `unsafe-best-match`: Search for each package across all indexes, and select the best version from
+  the combined set of candidate versions.
+
+While `unsafe-best-match` is the closest to pip's behavior, it exposes users to the risk of
+"dependency confusion" attacks.
+
+## Providing credentials
+
+Most private registries require authentication to access packages, typically via a username and
+password (or access token).
+
+To authenticate with a provide index, either provide credentials via environment variables or embed
+them in the URL.
+
+For example, given an index named `internal` that requires a username (`public`) and password
+(`koala`), define the index (without credentials) in your `pyproject.toml`:
+
+```toml
+[[tool.uv.index]]
+name = "internal"
+url = "https://example.com/simple"
+```
+
+From there, you can set the `UV_INDEX_INTERNAL_USERNAME` and `UV_INDEX_INTERNAL_PASSWORD`
+environment variables, where `INTERNAL` is the uppercase version of the index name:
+
+```sh
+export UV_INDEX_INTERNAL_USERNAME=public
+export UV_INDEX_INTERNAL_PASSWORD=koala
+```
+
+By providing credentials via environment variables, you can avoid storing sensitive information in
+the plaintext `pyproject.toml` file.
+
+Alternatively, credentials can be embedded directly in the index definition:
+
+```toml
+[[tool.uv.index]]
+name = "internal"
+url = "https://public:koala@https://pypi-proxy.corp.dev/simple"
+```
+
+For security purposes, credentials are _never_ stored in the `uv.lock` file; as such, uv _must_ have
+access to the authenticated URL at installation time.
+
+## `--index-url` and `--extra-index-url`
+
+In addition to the `[[tool.uv.index]]` configuration option, uv supports pip-style `--index-url` and
+`--extra-index-url` command-line options for compatibility, where `--index-url` defines the default
+index and `--extra-index-url` defines additional indexes.
+
+These options can be used in conjunction with the `[[tool.uv.index]]` configuration option, and
+follow the same prioritization rules:
+
+- The default index is always treated as lowest priority, whether defined via the legacy
+  `--index-url` argument, the recommended `--default-index` argument, or a `[[tool.uv.index]]` entry
+  with `default = true`.
+- Indexes are consulted in the order in which they’re defined, either via the legacy
+  `--extra-index-url` argument, the recommended `--index` argument, or `[[tool.uv.index]]` entries.
+
+In effect, `--index-url` and `--extra-index-url` can be thought of as unnamed `[[tool.uv.index]]`
+entries, with `default = true` enabled for the former. In that context, `--index-url` maps to
+`--default-index`, and `--extra-index-url` maps to `--index`.

-## Transitive direct URL dependencies for constraints and overrides
+## Transitive URL dependencies
 
-While uv does support URL dependencies (e.g., `black @ https://...`), it does not support
-_transitive_ (i.e., "nested") direct URL dependencies for constraints and overrides.
+While uv includes first-class support for URL dependencies (e.g., `ruff @ https://...`), it differs
+from pip in its handling of _transitive_ URL dependencies in two ways.
 
-Specifically, if a constraint or override is defined using a direct URL dependency, and the
-constrained package has a direct URL dependency of its own, uv _may_ reject that transitive direct
-URL dependency during resolution.
+First, uv makes the assumption that non-URL dependencies do not introduce URL dependencies into the
+resolution. In other words, it assumes that dependencies fetched from a registry do not themselves
+depend on URLs. If a non-URL dependency _does_ introduce a URL dependency, uv will reject the URL
+dependency during resolution. (Note that PyPI does not allow published packages to depend on URL
+dependencies; other registries may be more permissive.)
 
-uv also makes the assumption that non-URL dependencies won't introduce URL dependencies (i.e., that
-dependencies fetched from a registry will not themselves have direct URL dependencies). If a non-URL
-dependency _does_ introduce a URL dependency, uv will reject the URL dependency during resolution.
+Second, if a constraint (`--constraint`) or override (`--override`) is defined using a direct URL
+dependency, and the constrained package has a direct URL dependency of its own, uv _may_ reject that
+transitive direct URL dependency during resolution, if the URL isn't referenced elsewhere in the set
+of input requirements.
 
-If uv rejects a transitive URL dependency in either case, the best course of action is to provide
-the URL dependency as a direct dependency in the `requirements.in` file, rather than as a
-constraint, override, or transitive dependency.
+If uv rejects a transitive URL dependency, the best course of action is to provide the URL
+dependency as a direct dependency in the relevant `pyproject.toml` or `requirement.in` file, as the
+above constraints do not apply to direct dependencies.
