- Update to version 3.7.1
* Support for external data files such as man pages or Jupyter
extension support files (PR #510).
* Project names are now lowercase in wheel filenames and
.dist-info folder names, in line with the specifications (PR
#498).
* Improved support for bootstrapping a Python environment, e.g.
for downstream packagers (PR #511). 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 (PR
#499).
* Fix building packages which need execution to get the version
number, and have a relative import in __init__.py (PR #531).
