Updates the requirements on flit-core to permit the latest version.

Changelog

Sourced from flit-core's changelog.

Version 4.0.2

  • Fix invalid metadata files with Import-Name (:ghissue:813).

Version 4.0.1

No changes, but a new tag to trigger an upload to PyPI now that twine will accept it.

Version 4.0

This version contains breaking changes, but most projects which are already using the [project] table for metadata shouldn't be affected, and can simply change the flit_core <4 constraint to <5.

  • The [tool.flit.metadata] table is no longer used for project metadata (:ghpull:771). Use the newer :ref:[project] table <pyproject_toml_project> instead (or if that is not possible, build with flit_core <4).
  • :ref:build_cmd and :ref:publish_cmd no longer include files in the sdist based on what is committed in git or Mercurial (:ghpull:772). These commands now build packages more like Flit does when called as a backend by e.g. python -m build. Specify :ref:sdist include & exclude patterns <pyproject_toml_sdist> instead (Flit can help to generate these), or pass the --use-vcs option to get the old behaviour back.
  • flit_core now requires Python 3.8 or above (:ghpull:738)
  • The --setup-py option to generate sdists containing a setup.py file is no longer available (:ghpull:776).
  • Making typing stubs packages with a -stubs suffix will now work (:ghpull:742).
  • The default glob patterns for license files have been extended to include NOTICE* and AUTHORS* (:ghpull:758).
  • license-files glob patterns can contain spaces (:ghpull:797).
  • Fix a bug where license files could be found twice on Windows (:ghpull:752).
  • The new Import-Name and Import-Namespace metadata fields (metadata 2.5) are now supported (:ghpull:774). In most cases no new input is required, as Flit will create this metadata automatically.
  • Fix creating RECORD files when file names include commas (:ghpull:744).
  • The --use-vcs option now correctly recognises git from inside a git worktree folder (:ghpull:799).
  • On Python 3.12 and above, flit build now uses the 'data' filter when extracting the just-created sdist prior to building a wheel (:ghpull:775). This restricts some special features of tar files, but sdists are unlikely to use these features, and they would probably break in other scenarios if you did.
  • The vendorised readme_renderer package was updated to version 44.0 (:ghpull:760).

🔧 Include tests/ and tox.ini in the sdist (#426)
2700cc3 
## Summary

Supersedes #420 by @BetterAndBetterII (GitHub refused to update that
fork branch because the merge would carry workflow-file changes); their
commits are carried here verbatim with authorship preserved (thank
you!). Closes #261, open since 2023 from a distro packager.

PyPI sdists shipped `tox.ini` but omitted `tests/`, so packagers could
not run the suite from the tarball. `tests/` is moved out of
`[tool.flit.sdist] exclude` and `tests/` plus `tox.ini` are explicitly
included; `docs/` and `benchmarking/` stay excluded.

## Commits

1. `fix: include tests/ (and tox.ini) in the flit sdist` and the
pre-commit.ci autofix — the contributor's commits, unchanged.
2. `🧪 TEST: Assert sdist contents by building the sdist` — the original
test only string-matched `pyproject.toml`. It now builds a real sdist
with `flit_core` (no network, ~0.15 s) and asserts
`markdown_it/__init__.py`, `tests/test_api/test_main.py` and `tox.ini`
are members and nothing under `docs/` or `benchmarking/` is. It skips
cleanly when `flit_core` is unavailable or when not run from a source
checkout. Verified negative: with the `include` reverted, the test fails
on `tests/test_api/test_main.py`.

## Verification

- 994 tests pass; the sdist test runs (not skipped) with flit_core
4.0.2, which is what `pyproject.toml` now allows after #414.
- All pre-commit hooks pass under the new pins.
- No changelog entry in the commits; suggest adding one at release time
under 🔧.
