    - Replaced the implementation with code which parses requirements in
      accordance with PEP 508 and evaluates marker expressions according to
      PEP 508.

    - 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).

- 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,

      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.

      ``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.

    - Changed Wheel.install API (after consultation on distutils-sig).

    - Added support for PEP 426 JSON metadata (pydist.json).

    - Numerous documentation updates, not detailed further here.

- tests

    - Numerous test refinements, not detailed further here.

    - Handle None return from write_shared_locations correctly.
