What's Changed

• 🐛 fix(create): limit .venv redirect to projects by @​gaborbernat in pypa/virtualenv#3316

Full Changelog: pypa/virtualenv@21.12.0...21.12.1

Changelog

Sourced from virtualenv's changelog.

Bugfixes - 21.12.1

• Limit the :PEP:832 .venv redirect to folders holding a pyproject.toml and no .venv yet, so virtualenv foo in a scratch folder, and tools such as tox or nox building environments through virtualenv, no longer claim a folder's default environment - by :user:gaborbernat.

  • --venv-redirect writes the redirect in any folder and replaces an earlier virtualenv redirect.
  • A flag on the command line overrides the environment variable and the config file in either direction. (:issue:3316)

🤖 Claude Code Review

Review: Bump virtualenv 21.12.0 → 21.12.1

The only change is a patch-version bump of a pinned development dependency in pyproject.toml:46.

Code Quality

• ✅ Style: The change matches the existing pinned-version format.
• ✅ No commented-out code.
• ✅ Variable names, DRY: Not applicable.
• ✅ Defects: None expected. This is a patch release of a dev-only tool (development group), so it doesn't affect the library's runtime or its published dependencies. I did not check the upstream release notes, since there is no network access.
• ✅ .claude/CLAUDE.md: Not modified. The existing file has no environment-specific content.

Testing

• ✅ Unit and integration tests, edge cases, coverage: No new code was added, so none are needed. CI across Python 3.10–3.13 should confirm that the install resolves.

Documentation

• ✅ README and API docs: No update needed.
• ⚠️ CHANGELOG.md: Not updated. Dependabot bumps of dev-only tooling usually don't get an entry, and the previous virtualenv bumps (Bump virtualenv from 21.10.0 to 21.11.1 #162, Bump virtualenv from 21.11.1 to 21.12.0 #163) appear to follow the same pattern. This is optional.
• ✅ Markdown: No markdown files changed.

Security

• ✅ No credentials, license files (.lic) or AQAAAD strings in the diff.
• ✅ Input validation, error handling, logging: Not applicable.
• ✅ Supply chain: The version is pinned exactly (==), which is good practice, and it comes from a trusted Dependabot update.

Summary

Approve. This is a low-risk, dev-only patch bump. The only follow-up is to confirm that CI passes.
