Log Message:
py-importlib-metadata: update to 4.10.1.

v4.10.1
=======

* #361: Avoid potential REDoS in ``EntryPoint.pattern``.

v4.10.0
=======

* #354: Removed ``Distribution._local`` factory. This
  functionality was created as a demonstration of the
  possible implementation. Now, the
  `pep517 <https://pypi.org/project/pep517>`_ package
  provides this functionality directly through
  `pep517.meta.load \ 
<https://github.com/pypa/pep517/blob/a942316305395f8f757f210e2b16f738af73f8b8/pep517/meta.py#L63-L73>`_.

v4.9.0
======

* Require Python 3.7 or later.

v4.8.3
======

* #357: Fixed requirement generation from egg-info when a
  URL requirement is given.

v4.8.2
======

v2.1.2
======

* #353: Fixed discovery of distributions when path is empty.

v4.8.1
======

* #348: Restored support for ``EntryPoint`` access by item,
  deprecating support in the process. Users are advised
  to use direct member access instead of item-based access::

  - ep[0] -> ep.name
  - ep[1] -> ep.value
  - ep[2] -> ep.group
  - ep[:] -> ep.name, ep.value, ep.group

v4.8.0
======

* #337: Rewrote ``EntryPoint`` as a simple class, still
  immutable and still with the attributes, but without any
  expectation for ``namedtuple`` functionality such as
  ``_asdict``.

v4.7.1
======

* #344: Fixed regression in ``packages_distributions`` when
  neither top-level.txt nor a files manifest is present.

v4.7.0
======

* #330: In ``packages_distributions``, now infer top-level
  names from ``.files()`` when a ``top-level.txt``
  (Setuptools-specific metadata) is not present.

v4.6.4
======

* #334: Correct ``SimplePath`` protocol to match ``pathlib``
  protocol for ``__truediv__``.

v4.6.3
======

* Moved workaround for #327 to ``_compat`` module.

v4.6.2
======

* bpo-44784: Avoid errors in test suite when
  DeprecationWarnings are treated as errors.

v4.6.1
======

* #327: Deprecation warnings now honor call stack variance
  on PyPy.

v4.6.0
======

* #326: Performance tests now rely on
  `pytest-perf <https://pypi.org/project/pytest-perf>`_.
  To disable these tests, which require network access
  and a git checkout, pass ``-p no:perf`` to pytest.

v4.5.0
======

* #319: Remove ``SelectableGroups`` deprecation exception
  for flake8.

v4.4.0
======

* #300: Restore compatibility in the result from
  ``Distribution.entry_points`` (``EntryPoints``) to honor
  expectations in older implementations and issuing
  deprecation warnings for these cases:

  - ``EntryPoints`` objects are once again mutable, allowing
    for ``sort()`` and other list-based mutation operations.
    Avoid deprecation warnings by casting to a
    mutable sequence (e.g.
    ``list(dist.entry_points).sort()``).

  - ``EntryPoints`` results once again allow
    for access by index. To avoid deprecation warnings,
    cast the result to a Sequence first
    (e.g. ``tuple(dist.entry_points)[0]``).

v4.3.1
======

* #320: Fix issue where normalized name for eggs was
  incorrectly solicited, leading to metadata being
  unavailable for eggs.

v4.3.0
======

* #317: De-duplication of distributions no longer requires
  loading the full metadata for ``PathDistribution`` objects,
  entry point loading performance by ~10x.

v4.2.0
======

* Prefer f-strings to ``.format`` calls.

v4.1.0
======

* #312: Add support for metadata 2.2 (``Dynamic`` field).

* #315: Add ``SimplePath`` protocol for interface clarity
  in ``PathDistribution``.

v4.0.1
======

* #306: Clearer guidance about compatibility in readme.

v4.0.0
======

* #304: ``PackageMetadata`` as returned by ``metadata()``
  and ``Distribution.metadata()`` now provides normalized
  metadata honoring PEP 566:

  - If a long description is provided in the payload of the
    RFC 822 value, it can be retrieved as the ``Description``
    field.
  - Any multi-line values in the metadata will be returned as
    such.
  - For any multi-line values, line continuation characters
    are removed. This backward-incompatible change means
    that any projects relying on the RFC 822 line continuation
    characters being present must be tolerant to them having
    been removed.
  - Add a ``json`` property that provides the metadata
    converted to a JSON-compatible form per PEP 566.

v3.10.1
=======

* Minor tweaks from CPython.

v3.10.0
=======

* #295: Internal refactoring to unify section parsing logic.

v3.9.1
======

* #296: Exclude 'prepare' package.
* #297: Fix ValueError when entry points contains comments.

v3.9.0
======

* Use of Mapping (dict) interfaces on ``SelectableGroups``
  is now flagged as deprecated. Instead, users are advised
  to use the select interface for future compatibility.

  Suppress the warning with this filter:
  ``ignore:SelectableGroups dict interface``.

  Or with this invocation in the Python environment:
  ``warnings.filterwarnings('ignore', 'SelectableGroups dict interface')``.

  Preferably, switch to the ``select`` interface introduced
  in 3.7.0. See the
  `entry points documentation \ 
<https://importlib-metadata.readthedocs.io/en/latest/using.html#entry-points>`_ \ 
and changelog for the 3.6
  release below for more detail.

  For some use-cases, especially those that rely on
  ``importlib.metadata`` in Python 3.8 and 3.9 or
  those relying on older ``importlib_metadata`` (especially
  on Python 3.5 and earlier),
  `backports.entry_points_selectable \ 
<https://pypi.org/project/backports.entry_points_selectable>`_
  was created to ease the transition. Please have a look
  at that project if simply relying on importlib_metadata 3.6+
  is not straightforward. Background in #298.

* #283: Entry point parsing no longer relies on ConfigParser
  and instead uses a custom, one-pass parser to load the
  config, resulting in a ~20% performance improvement when
  loading entry points.

v3.8.2
======

* #293: Re-enabled lazy evaluation of path lookup through
  a FreezableDefaultDict.

v3.8.1
======

* #293: Workaround for error in distribution search.

v3.8.0
======

* #290: Add mtime-based caching for ``FastPath`` and its
  lookups, dramatically increasing performance for repeated
  distribution lookups.

v3.7.3
======

* Docs enhancements and cleanup following review in
  `GH-24782 <https://github.com/python/cpython/pull/24782>`_.

v3.7.2
======

* Cleaned up cruft in entry_points docstring.

v3.7.1
======

* Internal refactoring to facilitate ``entry_points() -> dict``
  deprecation.

v3.7.0
======

* #131: Added ``packages_distributions`` to conveniently
  resolve a top-level package or module to its distribution(s).

v3.6.0
======

* #284: Introduces new ``EntryPoints`` object, a tuple of
  ``EntryPoint`` objects but with convenience properties for
  selecting and inspecting the results:

  - ``.select()`` accepts ``group`` or ``name`` keyword
    parameters and returns a new ``EntryPoints`` tuple
    with only those that match the selection.
  - ``.groups`` property presents all of the group names.
  - ``.names`` property presents the names of the entry points.
  - Item access (e.g. ``eps[name]``) retrieves a single
    entry point by name.

  ``entry_points`` now accepts "selection parameters",
  same as ``EntryPoint.select()``.

  ``entry_points()`` now provides a future-compatible
  ``SelectableGroups`` object that supplies the above interface
  (except item access) but remains a dict for compatibility.

  In the future, ``entry_points()`` will return an
  ``EntryPoints`` object for all entry points.

  If passing selection parameters to ``entry_points``, the
  future behavior is invoked and an ``EntryPoints`` is the
  result.

* #284: Construction of entry points using
  ``dict([EntryPoint, ...])`` is now deprecated and raises
  an appropriate DeprecationWarning and will be removed in
  a future version.

* #300: ``Distribution.entry_points`` now presents as an
  ``EntryPoints`` object and access by index is no longer
  allowed. If access by index is required, cast to a sequence
  first.

v3.5.0
======

* #280: ``entry_points`` now only returns entry points for
  unique distributions (by name).

v3.4.0
======

* #10: Project now declares itself as being typed.
* #272: Additional performance enhancements to distribution
  discovery.
* #111: For PyPA projects, add test ensuring that
  ``MetadataPathFinder._search_paths`` honors the needed
  interface. Method is still private.

v3.3.0
======

* #265: ``EntryPoint`` objects now expose a ``.dist`` object
  referencing the ``Distribution`` when constructed from a
  Distribution.

v3.2.0
======

* The object returned by ``metadata()`` now has a
  formally-defined protocol called ``PackageMetadata``
  with declared support for the ``.get_all()`` method.
  Fixes #126.

v3.1.1
======

v2.1.1
======

* #261: Restored compatibility for package discovery for
  metadata without version in the name and for legacy
  eggs.

v3.1.0
======

* Merge with 2.1.0.

v2.1.0
======

* #253: When querying for package metadata, the lookup
  now honors
  `package normalization rules \ 
<https://packaging.python.org/specifications/recording-installed-packages/>`_.

v3.0.0
======

* Require Python 3.6 or later.
