Released: Not yet.

0.1.8 (future)

Released: 2014-03-18

    • Improved thread-safety in SimpleScrapingLocator (issue #45).
    • Replaced absolute imports with relative ones.
    • Added search method to PackageIndex.
  • locators

    • Improved thread-safety in SimpleScrapingLocator (issue #45).
  • metadata

    • Fixed bug in add_requirements implementation.
  • resources

    • The Cache class was refactored into distlib.util.Cache and distlib.resources.ResourceCache classes.
  • scripts

    • Implement quoting for executables with spaces in them.
  • util

    • Gained the Cache class, which is also used in distlib.wheel.
  • version

    • Allowed versions with a single numeric component and a local version component.
    • Adjusted pre-release computation for legacy versions to be the same as the logic in the setuptools documentation.
  • wheel

    • Added verify, update, is_compatible and is_mountable methods to the Wheel class.

    • If SOABI not available, used Py_DEBUG, Py_UNICODE_SIZE and WITH_PYMALLOC to derive the ABI.
    • Added "exists" property to Wheel instances.

    • Provided the ability to determine the location where extensions are extracted, by using the distlib.util.Cache class.
    • Avoided using pydist.json in 1.0 wheels (bdist_wheel writes a non-conforming pydist.json.)
    • Improved computation of compatible tags on OS X, and made COMPATIBLE_TAGS a set.
  • _backport/sysconfig

    • Replaced an absolute import with a relative one.

Released: 2013-12-15

  • compat

    • Changed source of import for unescape in Python >= 3.4.
  • index

    • Used dummy_threading when threading isn't available.
    • Used https for default index.
  • locators

0.1.4

Released: 2013-10-31

0.1.3

Released: 2013-10-18

  • database

    • Added support for PEP 426 JSON metadata (pydist.json).
    • Generalised digests to support e.g. SHA256.
    • Fixed a bug in parsing legacy metadata from .egg directories.
    • Removed duplicated code relating to parsing "provides" fields.
  • index

    • Changes relating to support for PEP 426 JSON metadata (pydist.json).
  • locators

    • Changes relating to support for PEP 426 JSON metadata (pydist.json).
    • Fixed a bug in scoring download URLs for preference when multiple URLs are available.
    • The legacy scheme is used for the default locator.
    • Made changes relating to parsing "provides" fields.
    • Generalised digests to support e.g. SHA256.
    • If no release version is found for a requirement, prereleases are now considered even if not explicitly requested.
  • markers

    • Added support for markers as specified in PEP 426.
  • metadata

    • Added support for PEP 426 JSON metadata (pydist.json). The old metadata class is renamed to LegacyMetadata, and the (new) Metadata class wraps the JSON format (and also the legacy format, through LegacyMetadata).
    • Removed code which was only used if docutils was installed. This code implemented validation of .rst descriptions, which is not done in distlib.
  • scripts

    • Updated the logic for writing executable files to deal as best we can with files which are already in use and hence cannot be deleted on Windows.
    • Changed the script generation when launchers are used to write a single executable which wraps a script (whether pre-built or generated) and includes a manifest to avoid UAC prompts on Windows.
    • Changed the interface for script generation options: the make and make_multiple methods of ScriptMaker now take an optional options dictionary.
  • util

    • Added extract_by_key() to copy selected keys from one dict to another.
    • Added parse_name_and_version() for use in parsing "provides" fields.
    • Made split_filename more flexible.
  • version

    • Added support for PEP 440 version matching.
    • Removed AdaptiveVersion, AdaptiveMatcher etc. as they don't add sufficient value to justify keeping them in.
  • wheel

    • Added wheel_version kwarg to Wheel.build API.
    • Changed Wheel.install API (after consultation on distutils-sig).
    • Added support for PEP 426 JSON metadata (pydist.json).
    • Added lib_only flag to install() method.
  • docs

    • Numerous documentation updates, not detailed further here.
  • tests

    • Numerous test refinements, not detailed further here.

  • metadata

  • scripts

    • Add variants and clobber flag for generation of foo/fooX/foo-X.Y.
    • Added .exe manifests for Windows.
  • util

    • Regularised recording of written files.
    • Added Configurator.
  • version

    • Tidyups, most suggested by Donald Stufft: Made key functions private, removed _Common class, removed checking for huge version numbers, made UnsupportedVersionError a ValueError.
  • wheel

    • Replaced absolute import with relative.
    • Handle None return from write_shared_locations correctly.
    • Fixed bug in Mounter for extension modules not in sub-packages.
    • Made dylib-cache Python version-specific.
