[dependabot]

Bumps virtualenv from 21.14.9 to 21.14.13.

Release notes

Sourced from virtualenv's releases.

21.14.13

Security

• Stop bash running commands from --prompt or an environment name containing $(...), backticks or a backslash after shopt -s promptvars, set -o posix, or in a child shell that inherits an exported PS1 (GHSA-cx6f-vjhg-g3cc); reported by @​rozzkml. zsh now draws the prompt from psvar[9], which is never parsed as shell syntax. (#3466) by @​gaborbernat.
• Write the .venv redirect and the wheel RECORD with exclusive create, so a link planted after the existence check cannot redirect the write. On POSIX, replace a read-only .venv redirect that points at a virtualenv. (#3466) by @​gaborbernat.

Bug fixes

• Search all directories supplied by repeated --extra-search-dir options instead of keeping only the last group. (#3440) by @​repzakske.
• On Windows, the app data is now migrated into the nested cache directory instead of the migration failing with a warning on every run. (#3441) by @​gaborbernat and @​XXXXXQ-0206.

🐍 PyPI release

📜 Full Changelog

21.14.10

Bug fixes

• Always copy seed packages when app-data is temporary, including when symlink seeding is enabled through an environment variable or configuration file. Seeded packages remain available after temporary cache cleanup. (#3437) by @​gaborbernat.

Fixed

• Clear inherited PYTHONHOME during PowerShell, Nushell, and programmatic activation so child interpreters use the environment's standard library. Preserve empty values when Bash and fish deactivate (:pr:3517) by :user:gaborbernat.
• Remove empty PATH entries during programmatic activation, including entries in an otherwise nonempty value. On POSIX, an empty entry searches the current directory (:pr:3513) by :user:qodelicious and :user:gaborbernat.
• Unset PYTHONHOME during C shell activation and restore its original value on deactivation. An inherited value could previously prevent the environment's Python interpreter from starting (:pr:3514) by :user:abhishekcpp007 and :user:gaborbernat.
