21.6.1

What's Changed

• 🐛 fix(fish): harden prompt against shadowed builtins by @​gaborbernat in pypa/virtualenv#3185

Full Changelog: pypa/virtualenv@21.6.0...21.6.1

Changelog

Sourced from virtualenv's changelog.

Bugfixes - 21.6.1

• Harden the fish activator prompt against user functions that shadow builtins. Routing functions, printf, string, echo and source/. through builtin stops a shadowing function (such as a dot-style directory navigator that redefines .) from hijacking the prompt and dropping the previous command's exit status, matching the CPython fix in [gh-140006](https://github.com/pypa/virtualenv/issues/140006) <https://github.com/python/cpython/issues/140006>_. (:issue:3185)

🤖 Claude Code Review

Confirmed this is a standard dependabot dependency-bump PR, consistent with prior similar bumps in the repo (which also didn't touch CHANGELOG.md). Here's the review.

PR Review: Bump virtualenv 21.6.0 → 21.6.1

Summary: Single-line patch-version bump of the virtualenv dev dependency pin in pyproject.toml, generated by dependabot. This follows the exact same pattern as prior merged bumps (e.g. 2c81eec for 21.5.1→21.6.0), which also made no other file changes.

Code Quality

• ✅ Style: consistent with existing pin format in the development extras list (pyproject.toml:46).
• ✅ No commented-out code.
• ✅ N/A — no new identifiers introduced.
• ✅ DRY — trivial single-line change.
• ✅ No defects — patch version bump, no logic changed. No .claude/CLAUDE.md changes in this diff.

Testing

• ✅ N/A — no new functions/endpoints; a dependency version bump doesn't need new tests. Existing CI will validate installability.

Documentation

• ❌ CHANGELOG.md not updated, but consistent with prior dependency-bump PRs in this repo's history (none of them touch CHANGELOG.md either) — not a blocker, just noting the existing convention.
• ✅ No README/API doc changes needed.
• ✅ No markdown files touched.

Security

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

Verdict: Safe to merge. No issues found; matches repo's established pattern for dependabot patch bumps.

🤖 Claude Code Review

This is a trivial, automated Dependabot dependency bump (virtualenv 21.6.0 → 21.6.1) in pyproject.toml. Here's the review:

Code Quality

• ✅ Follows standard conventions — single-line version pin change, consistent with the file's existing format (pyproject.toml:46)
• ✅ No commented-out code
• ✅ N/A — no variable names introduced
• ✅ N/A — no logic duplicated
• ✅ No defects: this is a patch-level bump of a pinned dev dependency (virtualenv), scoped to the development dependency group. No functional code is touched, so no new bugs, race conditions, or crashes are introduced.
• ✅ .claude/CLAUDE.md reviewed — content is general project guidance (install/lint/run commands, architecture overview) with no local-machine-specific paths, credentials, or environment assumptions. No changes needed, and this PR doesn't touch it anyway.

Testing

• ✅ N/A — dependency version bump only, no new functions/endpoints requiring tests
• ✅ N/A — no new endpoints
• ✅ N/A — no new logic/edge cases
• ✅ N/A — no code coverage impact

Documentation

• ✅ N/A — no README-relevant behavior change
• ✅ N/A — no API changes
• ✅ N/A — no complex logic added
• ❌ CHANGELOG.md not updated. Prior dependency bumps in this repo's history (2c81eec, 5507b31, etc.) also appear to skip CHANGELOG entries for routine Dependabot patch bumps, so this is consistent with existing project practice rather than a deviation — flagging for awareness only, not a blocker.
• ✅ N/A — no markdown files changed in this diff

Security

• ✅ No hardcoded credentials
• ✅ N/A — no input handling changed
• ✅ N/A — no error handling changed
• ✅ No sensitive data in logs
• ✅ No .lic files or AQAAAD-prefixed strings found in this diff or the repo tree (checked)

Summary

Low-risk, routine dependency patch bump. No blocking issues found. Approve.
