Changelog

Sourced from virtualenv's changelog.

Bugfixes - 21.7.8

• A missing source needed by both install modes now disables the builtin creator through meta.error. The check compared RefWhen values against RefMust members, so creation went on to fail with a FileNotFoundError or a dangling symlink - by :user:darrenhuai. (:issue:3227)

🤖 Claude Code Review

Looking at this diff, it's a trivial dependency bump — no functional or documentation changes to review in depth.

Review Result

Diff scope: pyproject.toml — bumps virtualenv dev dependency from 21.7.7 to 21.7.8.

Code Quality

• ✅ Single-line version pin bump, follows existing formatting conventions in the file.
• ✅ No commented-out code.
• ✅ N/A — no variables introduced.
• ✅ N/A — no logic duplicated.
• ✅ No defects possible — this is a pinned dev-tool version bump, not runtime code. No bugs, race conditions, or crashes introduced.
• ✅ .claude/CLAUDE.md reviewed — content is general (build/run instructions, environment setup, conventions) and not specific to any individual's local machine. No changes needed here since this PR doesn't touch it.

Testing

• ✅ N/A — dependency version bump requires no new tests. virtualenv is a dev-only tool (used for lint/dev environments), not part of the runtime snippets.

Documentation

• ✅ N/A — no README/API/CHANGELOG impact expected for a patch-level dev dependency bump. (Note: repo has no CHANGELOG.md referenced in this diff to verify against.)
• ✅ No markdown files changed.

Security

• ✅ No hardcoded credentials.
• ✅ N/A — no input handling changed.
• ✅ N/A — no error handling changed.
• ✅ No sensitive data.
• ✅ No .lic files or AQAAAD-prefixed strings present in this diff.

Summary

This is a safe, routine dependency bump (likely automated, e.g. Dependabot) with no concerns. Approved.
