**Breaking**

- {obj}`--windows_enable_symlinks` is required. Add `startup
--windows_enable_symlinks` to your `.bazelrc` to enable Bazel using full
  symlink support on Windows.
- venv-based binaries are created by default
({obj}`--bootstrap_impl=system_python`)
  on supported platforms (Linux/Mac with Bazel 8+, or Windows).
- `--build_python_zip` on Windows is ignored. Use
{obj}`py_zipapp_binary` to create
  zips of Python programs.
- (pypi) Previously `experimental_index_url` users would not need to
specify
target platforms if cross-building is required. From now we will only
pull
wheels for the host OS to better align with how the rules work with the
legacy
`pip` implementation. Use {obj}`pip.parse.target_platforms` to customize
the
  behavior.
Related to
[#&#8203;260](https://redirect.github.com/bazel-contrib/rules_python/issues/260).

Other changes:

- (pypi) Update dependencies used for `compile_pip_requirements`,
building
  sdists in the `whl_library` rule and fetching wheels using `pip`.
- (pypi) Before using the bazel downloader to fetch the PyPI package
metadata
we will from now on fetch the lists of available packages on each index.
The
used package mappings will be written as facts to the
`MODULE.bazel.lock` file
on supported bazel versions and it should be done at most once. As a
result,
per-package {obj}`experimental_index_url_overrides` is no longer needed,
but
if specified, it needs to be provided for all packages not on the
default index. What
is more, the flags for `--index_url` and `--extra-index-url` now behave
in the
same way as in `uv` or `pip`, i.e. we default to `--index-url` if the
package
  is not found in `--extra-index-url`.  Fixes

([#&#8203;3260](https://redirect.github.com/bazel-contrib/rules_python/issues/3260)
and

[#&#8203;2632](https://redirect.github.com/bazel-contrib/rules_python/issues/2632)).
- (uv) We will now use the download URL specified in the `uv`'s
`dist_manifest.json` file. If you have redirects or blocking rules as
part of
your downloader setup, you may need to adjust them. What is more, the
default
  uv version has been bumped `0.11.2`.
- (runfiles): Type annotations are no longer tested for Python 3.9.
- Windows no longer defaults to creating a zip file and extracting it; a
  symlink-based runfiles tree is created, as on unix-like platforms.

{#v2-0-0-fixed}

##### Fixed

- (toolchain) Also set Make variables for local toolchains.
- (zipapp) Resolve issue passing through compression settings in
  `py_zippapp_binary` targets

([#&#8203;3646](https://redirect.github.com/bazel-contrib/rules_python/issues/3646)).
- (toolchains) The pyc created at runtime in the stdlib should no longer
cause the Python runtime repository to be invalidated. The stdlib pyc
files
  *may* be reused in between invocations, depending upon the sandboxing
configuration. See the {any}`RULES_PYTHON_PYCACHE_DIR` environment
variable
  for more information.

([#&#8203;3643](https://redirect.github.com/bazel-contrib/rules_python/issues/3643)).
- (bootstrap) Fixed incorrect runfiles path construction in bootstrap
  scripts when binary is defined in another bazel module

([#&#8203;3563](https://redirect.github.com/bazel-contrib/rules_python/issues/3563)).
- (bootstrap) Resolve `RUNFILES_DIR` inheritance issues, which lead to a
child
Python binary incorrectly using it's parent's Python binary environment

([#&#8203;3518](https://redirect.github.com/bazel-contrib/rules_python/issues/3518)).
- (uv) Downloads for versions `>=0.10` work again. In order to fix this
we had
drop support for `powerpc64` platform. People interested in the platform
can
  bring it back via the `uv.default` API. Like:
  ```
  uv.default(
      compatible_with = [
          "@&#8203;platforms//os:linux",
          "@&#8203;platforms//cpu:ppc",
      ],
      platform = "powerpc64-unknown-linux-gnu",
  )
  ```
Fixes
[#&#8203;3676](https://redirect.github.com/bazel-contrib/rules_python/issues/3676).
- (pypi) Fixes wheel extraction on hosts without python installed,
Fixes
[#&#8203;3712](https://redirect.github.com/bazel-contrib/rules_python/issues/3712).

{#v2-0-0-added}

##### Added

- (pypi) Write SimpleAPI contents to the `MODULE.bazel.lock` file if
using
  {obj}`experimental_index_url` which should speed up consecutive
initializations and should no longer require the network access if the
cache is
  hydrated.  Implements

[#&#8203;2731](https://redirect.github.com/bazel-contrib/rules_python/issues/2731).
- (pypi) The `--index-url` and `--extra-index-url` is now parsed from
the lock
  file and the {obj}`pip.parse.experimental_index_url` and
  {obj}`pip.parse.experimental_extra_index_urls` is
  no longer mandatory to leverage the bazel downloader.
  Implements

[#&#8203;1357](https://redirect.github.com/bazel-contrib/rules_python/issues/1357),

[#&#8203;2951](https://redirect.github.com/bazel-contrib/rules_python/issues/2951).
- (pypi) If cross-compilation is needed, use the
{obj}`pip.parse.target_platforms`
  to specify exactly which platforms should be supported.
  Implements

[#&#8203;260](https://redirect.github.com/bazel-contrib/rules_python/issues/260).
- (wheel) Specifying a path ending in `/` as a destination in
`data_files`
  will now install file(s) to a folder, preserving their basename.
- Various attributes and fields added to support venvs on Windows:
  - {obj}`py_runtime.venv_bin_files` and {obj}`PyRuntime.venv_binfiles`
field added to specify additional Python runtime files Windows needs for
    venvs.
  - {obj}`PyExecutableInfo.venv_interpreter_runfiles`, and
    {obj}`PyExecutableInfo.venv_interpreter_symlinks` adde
- (wheel) Add support for `add_path_prefix` argument in `py_wheel` which
can be
  used to prepend a prefix to the files in the wheel.
