release: 4.0.1

[PurpleToti]

Summary

• Bumps version to 4.0.1 in pyproject.toml
• Adds Bug: ModelSelect2Multiple without URL only renders already-selected choices in 4.0.0 (regression from 3.x) #1417 to the 4.0.1 CHANGELOG entry

Context

#1417 reports a regression in 4.0.0 where ModelSelect2(Multiple) without an AJAX URL only renders already-selected choices on edit forms. The root cause was Select2InitialRenderMixin.render() (added in 9eabac0) unconditionally filtering choices.queryset to pk__in=selected_pks at render time, regardless of whether a URL was configured. This was already fixed in master by 12efd27 (removed the mixin entirely). The fix just needs to ship as a patch release.

The 4.0.1 CHANGELOG stub already existed (for #1333); this PR adds the #1417 entry and bumps the version so a PyPI release can be cut.

Test plan

• Confirm python -m build produces a 4.0.1 wheel/sdist
• Verify ModelSelect2Multiple(url=None) on an edit form shows the full queryset
• Publish to PyPI and close Bug: ModelSelect2Multiple without URL only renders already-selected choices in 4.0.0 (regression from 3.x) #1417

Summary by CodeRabbit

• Bug Fixes
  • Fixed a regression in ModelSelect2(Multiple) widgets that was introduced in the previous release. Widgets without a configured URL now correctly display the complete queryset when initially rendering on the page, instead of limiting available choices to only those specific items that were previously selected by the user in their prior interactions.

A tiny hop to fix a hop,
When widgets showed just chosen tops,
Now queryset flows like water free,
In 4.0.1, all choices we see! 🐰✨
