📜 Full Changelog

21.15.3

Bug fixes

• Add the environment's lib/pkgconfig to PKG_CONFIG_PATH when activating from xonsh, and restore the previous value or unset it again on deactivate, as the other activators already do (#3505) by @​darrenhuai and @​gaborbernat.
• Read virtualenv.ini values without interpolation, as environment variables and command line flags already are. A value holding a %, such as prompt = 50% done, was ignored without any message. %% and %(name)s are now kept as written, so write a single % (#3501) by @​darrenhuai and @​gaborbernat.
• Reject a destination that already exists but is not a directory, such as /dev/null, a FIFO or a socket, or that sits inside one, with a usage error instead of a NotADirectoryError once creation has started. A regular file now gets the same is not a directory message instead of is a file (#3504) by @​darrenhuai and @​gaborbernat.
• Set TCL_LIBRARY and TK_LIBRARY to the interpreter's Tcl/Tk paths in activate.nu, as the other activators do. Nushell activation used to leave both variables as they were (#3502) by @​darrenhuai and @​gaborbernat.
• Show the environment name in the zsh prompt when KSH_ARRAYS is set at activation. Since 21.14.13 the prompt read an empty psvar entry under that option and showed () instead of the name (#3506) by @​PDGGK and @​gaborbernat.
• Treat an empty or blank VIRTUALENV_OVERRIDE_APP_DATA and an empty VIRTUALENV_CONFIG_FILE as unset, as virtualenv already does for its option variables. An empty app-data override, or on Windows one made of spaces, made the current directory the cache, so --reset-app-data deleted it, and an empty config file path logged an error on every run (#3503) by @​darrenhuai and @​gaborbernat.

21.15.6 (2026-11-06)

.. _release-21-15-6-fixed:

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.
