Version 3.7.1
Fix building packages which need execution to get the version number, and have a relative import in __init__.py.
Version 3.7
Support for external data files such as man pages or Jupyter extension support files.
Project names are now lowercase in wheel filenames and .dist-info folder names, in line with the specification.
Improved support for bootstrapping a Python environment, e.g. for downstream packagers. flit_core.wheel is usable with python -m to create wheels before the build tool is available, and flit_core sdists also include a script to install itself from a wheel before installer is available.
Use newer importlib APIs, fixing some deprecation warnings
