Changelog

Sourced from virtualenv's changelog.

Bugfixes - 21.7.12

• Fix activate.bat running arbitrary commands from a crafted --prompt, VIRTUALENV_PROMPT, or config file value. (:issue:3250)
• Verify a downloaded seed wheel's sha256 against PyPI before seeding it into a virtual environment, skipped when a custom pip index is configured. (:issue:3251)

v21.7.11 (2026-09-17)

---

Bugfixes - 21.7.11

• Running activate.bat again before deactivate no longer makes deactivate leave the environment's PKG_CONFIG_PATH, TCL_LIBRARY and TK_LIBRARY behind, or lose values the user had set before the first activation - by :user:darrenhuai. (:issue:3245)
• Write pyvenv.cfg values on a single line, so a prompt carrying a line boundary can no longer inject configuration. --prompt, the VIRTUALENV_PROMPT environment variable and the config file all set the prompt, and pyvenv.cfg has no escape syntax, so a newline, a carriage return, or any other boundary str.splitlines recognizes, such as U+2028, started a new configuration line. Reading the file back picked up those lines as keys, and since the last value for a key wins, they replaced anything written earlier, including home. (:issue:3247)

Improved Documentation - 21.7.11

• Document the policy for AI-assisted contributions and the licensing rules for dependencies. (:issue:3239)

Misc - 21.7.11

• :issue:3238, :issue:3240, :issue:3241, :issue:3242, :issue:3243, :issue:3244, :issue:3246

v21.7.10 (2026-09-15)

---

Bugfixes - 21.7.10

• Skip blank lines, # comments and lines without = in pyvenv.cfg instead of raising ValueError - by :user:r3wretrhy. (:issue:3232)
• deactivate in bash, fish and PowerShell unsets PKG_CONFIG_PATH when activation found it unset, instead of keeping the environment's lib/pkgconfig. csh activation no longer drops a PKG_CONFIG_PATH the user had set. Activation in batch, fish, nushell and PowerShell no longer adds a trailing separator when PKG_CONFIG_PATH is unset, and PowerShell and nushell build the value with the host's path separators - by :user:darrenhuai. (:issue:3233)
• Activation in bash, csh, fish and PowerShell keeps the user's TCL_LIBRARY and TK_LIBRARY, and deactivate restores them. csh and PowerShell removed both variables on every activation, fish did so when the interpreter has

🤖 Claude Code Review

PR Code Review: Bump virtualenv 21.7.9 → 21.7.12

The diff changes one line in pyproject.toml:46. It bumps the pinned dev dependency virtualenv from 21.7.9 to 21.7.12. I reviewed only the diff and did not run the tests or the linter. I also did not check whether CHANGELOG.md has entries for earlier dependency bumps.

Code Quality

• ✅ Style conventions: The change keeps the existing exact-pin format (==) and the alphabetical ordering in the development group.
• ✅ No commented-out code: None added.
• ✅ Meaningful variable names: Not applicable.
• ✅ DRY: Not applicable.
• ✅ Defects: No code changes. It is a patch-level bump of a development-only tool, so it is not a runtime dependency of the mapper. The risk is low. CI on Python 3.10–3.13 should confirm that the dependency installs.
• ✅ .claude/CLAUDE.md: Not modified. The existing content is general and has nothing specific to a local environment.

Testing

• ✅ Unit and integration tests: Not applicable, since no code or endpoints changed.
• ✅ Edge cases: Not applicable.
• ✅ Coverage: Unaffected.

Documentation

• ✅ README and API docs: No update needed.
• ⚠️ CHANGELOG.md: Not updated in this PR. The recent history (Bump coverage from 7.15.4 to 7.16.0 #120–Bump virtualenv from 21.7.8 to 21.7.9 #122) shows similar routine Dependabot bumps. If the project doesn't log those, no action is needed. Otherwise, add an entry.
• ✅ Inline comments: Not applicable.
• ✅ Markdown/CommonMark/prettier: No Markdown files changed.

Security

• ✅ No hardcoded credentials: None.
• ✅ Input validation and error handling: Not applicable.
• ✅ No sensitive data in logs: Not applicable.
• ✅ License files: No .lic files and no strings starting with AQAAAD in the diff.

Summary

This is a safe, minimal dependency bump with no blocking issues. The only follow-up is to confirm the project's CHANGELOG policy for dependency bumps. CI should also pass across the supported Python versions before the merge.
