v6.4.5

Bugfixes

  • Omit sentinel values from a namespace path. (#311)

v6.4.4

No significant changes.

v6.4.3

Bugfixes

  • When inferring the caller in files() correctly detect one's own module even when the resources package source is not present. (python/cpython#123085)

Bugfixes

  • Restored expectation that stdlib readers are suppressed on Python 3.10. (#257)

v6.3.0

Features

  • Add Anchor to importlib.resources (in order for the code to comply with the documentation)

v6.2.0

Features

  • Future compatibility adapters now ensure that standard library readers are replaced without overriding non-standard readers. (#295)

v6.1.3

No significant changes.

v6.1.2

Bugfixes

  • Fixed NotADirectoryError when calling files on a subdirectory of a namespace package. (#293)

v6.1.1

Bugfixes

v6.1.0

Features

  • MultiplexedPath now expects Traversable paths. String arguments to MultiplexedPath are now deprecated.

Bugfixes

  • Enabled support for resources in namespace packages in zip files. (#287)

v6.0.1

Bugfixes

  • Restored Apache license. (#285)

v6.0.0

Deprecations and Removals

  • Removed legacy functions deprecated in 5.3. (#80)

v5.13.0

Features

  • Require Python 3.8 or later.

v5.12.0

  • #257: importlib_resources (backport) now gives precedence to built-in readers (file system, zip, namespace packages), providing forward-compatibility of behaviors like MultiplexedPath.

v5.11.1

v5.10.4

  • #280: Fixed one more EncodingWarning in test suite.

v5.11.0

  • #265: MultiplexedPath now honors multiple subdirectories in iterdir and joinpath.

v5.10.3

  • Packaging refresh, including fixing EncodingWarnings and some tests cleanup.

v5.10.2

  • #274: Prefer write_bytes to context manager as proposed in gh-100586.

v5.10.1

  • #274: Fixed ResourceWarning in _common.

v5.10.0

  • #203: Lifted restriction on modules passed to files. Now modules need not be a package and if a non-package module is passed, resources will be resolved adjacent to those modules, even for modules not found in any package. For example, files(import_module('mod.py')) will resolve resources found at the root. The parameter to files was renamed from 'package' to 'anchor', with a compatibility shim for those passing by keyword.
  • #259: files no longer requires the anchor to be specified and can infer the anchor from the caller's scope (defaults to the caller's module).

v5.9.0

  • #228: as_file now also supports a Traversable representing a directory and (when needed) renders the full tree to a temporary directory.

v5.8.1

  • #253: In MultiplexedPath, restore expectation that a compound path with a non-existent directory does not raise an exception.

v5.8.0

  • #250: Now Traversable.joinpath provides a concrete implementation, replacing the implementation in .simple and converging with the behavior in MultiplexedPath.

v5.7.1

  • #249: In simple.ResourceContainer.joinpath, honor names split by posixpath.sep.

v5.7.0

  • #248: abc.Traversable.joinpath now allows for multiple arguments and specifies that posixpath.sep is allowed in any argument to accept multiple arguments, matching the behavior found in zipfile.Path and pathlib.Path.

    simple.ResourceContainer now honors this behavior.

v5.6.0

  • #244: Add type declarations in ABCs.

v5.5.0

  • Require Python 3.7 or later.
  • #243: Fix error when no __pycache__ directories exist when testing update-zips.

v5.4.0

  • #80: Test suite now relies entirely on the traversable API.

v5.3.0

  • #80: Now raise a DeprecationWarning for all legacy functions. Instead, users should rely on the files() API introduced in importlib_resources 1.3. See Migrating from Legacy for guidance on avoiding the deprecated functions.

v5.2.3

  • Updated readme to reflect current behavior and show which versions correspond to which behavior in CPython.

v5.0.7

  • bpo-45419: Correct DegenerateFiles.Path .name and .open() interfaces to match Traversable.

v5.2.2

  • #234: Fix refleak in as_file caught by CPython tests.

v5.2.1

  • bpo-38291: Avoid DeprecationWarning on typing.io.

v5.2.0

  • #80 via #221: Legacy API (path, contents, ...) is now supported entirely by the .files() API with a compatibility shim supplied for resource loaders without that functionality.

v5.0.6

  • bpo-38693: Prefer f-strings to .format calls.

v5.1.4

  • #225: Require zipp 3.1.0 or later on Python prior to 3.10 to incorporate those fixes.

v5.0.5

  • #216: Make MultiplexedPath.name a property per the spec.

v5.1.3

  • Refresh packaging and improve tests.
  • #216: Make MultiplexedPath.name a property per the spec.

v5.1.2

  • Re-release with changes from 5.0.4.

v5.0.4

  • Fixed non-hermetic test in test_reader, revealed by GH-24670.

v5.1.1

  • Re-release with changes from 5.0.3.

v5.0.3

  • Simplified DegenerateFiles.Path.

v5.0.2

  • #214: Added _adapters module to ensure that degenerate files behavior can be made available for legacy loaders whose resource readers don't implement it. Fixes issue where backport compatibility module was masking this fallback behavior only to discover the defect when applying changes to CPython.

v5.1.0

  • Added simple module implementing adapters from a low-level resource reader interface to a TraversableResources interface. Closes #90.

v5.0.1

  • Remove pyinstaller hook for hidden 'trees' module.

v5.0.0

  • Removed importlib_resources.trees, deprecated since 1.3.0.

v4.1.1

  • Fixed badges in README.

v4.1.0

  • #209: Adopt jaraco/skeleton.
  • Cleaned up some straggling Python 2 compatibility code.
  • Refreshed test zip files without .pyc and .pyo files.

v4.0.0

  • #108: Drop support for Python 2.7. Now requires Python 3.6+.

v3.3.1

  • Minor cleanup.

v3.3.0

  • #107: Drop support for Python 3.5. Now requires Python 2.7 or 3.6+.

v3.2.1

  • #200: Minor fixes and improved tests for namespace package support.

v3.2.0

  • #68: Resources in PEP 420 Namespace packages are now supported.

v3.1.1

  • bpo-41490: contents is now also more aggressive about consuming any iterator from the Reader.

v3.1.0

  • #110 and bpo-41490: path method is more aggressive about releasing handles to zipfile objects early, enabling use-cases like certifi to leave the context open but delete the underlying zip file.

v3.0.0

  • Package no longer exposes importlib_resources.__version__. Users that wish to inspect the version of importlib_resources should instead invoke .version('importlib_resources') from importlib-metadata ( stdlib or backport) directly. This change eliminates the dependency on importlib_metadata. Closes #100.
  • Package now always includes its data. Closes #93.
  • Declare hidden imports for PyInstaller. Closes #101.

v2.0.1

v2.0.0

  • Loaders are no longer expected to implement the abc.TraversableResources interface, but are instead expected to return TraversableResources from their get_resource_reader method.

v1.5.0

  • Traversable is now a Protocol instead of an Abstract Base Class (Python 2.7 and Python 3.8+).
  • Traversable objects now require a .name property.

v1.4.0

  • #79: Temporary files created will now reflect the filename of their origin.

v1.3.1

  • For improved compatibility, importlib_resources.trees is now imported implicitly. Closes #88.

v1.3.0

  • Add extensibility support for non-standard loaders to supply Traversable resources. Introduces a new abstract base class abc.TraversableResources that supersedes (but implements for compatibility) abc.ResourceReader. Any loader that implements (implicitly or explicitly) the TraversableResources.files method will be capable of supplying resources with subdirectory support. Closes #77.
  • Preferred way to access as_file is now from top-level module. importlib_resources.trees.as_file is deprecated and discouraged. Closes #86.
  • Moved Traversable abc to abc module. Closes #87.

v1.2.0

  • Traversable now requires an open method. Closes #81.
  • Fixed error on Python 3.5.{0,3}. Closes #83.
  • Updated packaging to resolve version from package metadata. Closes #82.

v1.1.0

  • Add support for retrieving resources from subdirectories of packages through the new files() function, which returns a Traversable object with joinpath and read_* interfaces matching those of pathlib.Path objects. This new function supersedes all of the previous functionality as it provides a more general-purpose access to a package's resources.

    With this function, subdirectories are supported (Closes #58).

    The documentation has been updated to reflect that this function is now the preferred interface for loading package resources. It does not, however, support resources from arbitrary loaders. It currently only supports resources from file system path and zipfile packages (a consequence of the ResourceReader interface only operating on Python packages).

1.0.2

  • Fix setup_requires and install_requires metadata in setup.cfg. Given by Anthony Sottile.

1.0.1

  • Update Trove classifiers. Closes #63

1.0

  • Backport fix for test isolation from Python 3.8/3.7. Closes #61

0.8

  • Strip importlib_resources.__version__. Closes #56
  • Fix a metadata problem with older setuptools. Closes #57
  • Add an __all__ to importlib_resources. Closes #59

0.7

  • Fix setup.cfg metadata bug. Closes #55

0.6

  • Move everything from pyproject.toml to setup.cfg, with the added benefit of fixing the PyPI metadata. Closes #54
  • Turn off mypy's strict_optional setting for now.

0.5

  • Resynchronize with Python 3.7; changes the return type of contents() to be an Iterable. Closes #52

0.4

  • Correctly find resources in subpackages inside a zip file. Closes #51

0.3

  • The API, implementation, and documentation is synchronized with the Python 3.7 standard library. Closes #47
  • When run under Python 3.7 this API shadows the stdlib versions. Closes #50

0.2

  • Backward incompatible change. Split the open() and read() calls into separate binary and text versions, i.e. open_binary(), open_text(), read_binary(), and read_text(). Closes #41
  • Fix a bug where unrelated resources could be returned from contents(). Closes #44
  • Correctly prevent namespace packages from containing resources. Closes #20

0.1

  • Initial release.
