Changelog

Sourced from virtualenv's changelog.

Bugfixes - 21.7.13

• Fix activate and activate.fish running commands embedded in the virtual environment path or in the interpreter's Tcl/Tk library paths. (:issue:3252)

---

v21.7.12 (2026-09-18)

---

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)
