Changelog

Sourced from flit's changelog.

Release history

Version 3.10

• flit publish can now use PyPI tokens stored in keyring (:ghpull:649), either project tokens with a 'username' like :samp:pypi_token:project:{project_name} (use the normalised form of the name <https://packaging.python.org/en/latest/specifications/name-normalization/>_) or user tokens (:samp:pypi_token:user:{username}).
• The --python option can now take the path of a virtualenv folder, as an alternative to a Python executable (:ghpull:667).
• Flit will work with current development versions of Pythona again (:ghpull:684).
• The flit command line package now requires Python 3.8 or above (:ghpulL:660). flit_core still works with Python 3.6 or above.
• The metadata in packages now has the names of optional dependency groups ("extras") normalised, complying with version 2.3 of the metadata standard (:ghpull:676, :ghpull:697).
• The flit command line package now depends on pip (:ghpull:647).
• Fix potential substitution of environment variables into passwords read from .pypirc files (:ghpull:652).
• A warning is now shown when building packages which specify the old flit.buildapi backend, which should be replaced by flit_core.buildapi (:ghpull:674). It's a good idea to always set a maximum version for the build requirement, to protect against changes in future major versions of Flit.
• Avoid using the deprecated datetime.utcfromtimestamp() (:ghpull:682).
• Flit now has a SECURITY.md file in the Github repository (:ghpull:665).
• The tests for flit_core are no longer part of the installed package, reducing the size of the wheels (:ghpull:691).

Version 3.9

• New options :option:flit build --use-vcs and :option:flit build --no-use-vcs to enable & disable including all committed files in the sdist. For now --use-vcs is the default, but this is likely to change in a future version, to bring flit build in line with standard build frontends like python -m build (:ghpull:625).
• Sdist file names, and the name of the top-level folder in an sdist, are now normalised, in accordance with :pep:625 (:ghpull:628).
• A statically defined version number can now be parsed from files called version.py, _version.py or __version__.py inside a package, as well as from __init__.py, so executing code is required in fewer cases (:ghpull:630).
• Fix setting the flag for regular files in zip metadata (:ghpull:639).
• The timestamp embedded in the gzip wrapper for sdists now defaults to a fixed date, so building an sdist twice on the same machine should produce identical results, even without any special steps (:ghpull:635). Setting :envvar:SOURCE_DATE_EPOCH is still recommended for properly
