~~~~~

- Used https for default index.

~~~~~

Released: 2013-10-31

- scripts

- Updated the logic for finding the distlib package using a relative,
rather than absolute method. This fixes a problem for pip, where
distlib is kept in the pip.vendor.distlib package.

- _backport/sysconfig

- The analogous change to that made for scripts, described above.

~~~~~

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.

- Added .exe manifests for Windows.

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.
