Changelog

Sourced from virtualenv's changelog.

Bugfixes - 21.5.1

• Refuse to create environments whose Python the bundled wheels no longer cover (currently below 3.9). virtualenv used to substitute the newest bundled pip, which cannot run on such a target, leaving a broken environment; seeder selection now rejects it up front with a clear error. --no-seed and third-party seeders that ship compatible wheels still work - by :user:gaborbernat. (:issue:3171)

---

v21.5.0 (2026-06-13)

---

Features - 21.5.0

• Drop support for Python 3.8; virtualenv now requires Python 3.9 or later to run and to create environments. Remove the embedded wheel seed package, which virtualenv bundled only for Python 3.8. The --wheel and --no-wheel options stay as no-ops, but now warn that virtualenv will remove them in a release after 2026-12 - by :user:gaborbernat. (:issue:3170)

Bugfixes - 21.5.0

• Upgrade embedded wheels:

  Removed wheel of 0.47.0 (:issue:u)

---

v21.4.3 (2026-06-11)

---

Bugfixes - 21.4.3

• Upgrade embedded wheels:

  • pip to 26.1.2 from 26.1.1 (:issue:u)

• Resolve executable-only symlinks when recording home and base-executable in pyvenv.cfg, mirroring CPython's getpath.realpathpython/cpython#115237 binary locate the base stdlib (for example python-build-standalone); a fully symlinked interpreter tree is kept as-is

  • by :user:gaborbernat. (:issue:3157)

• Stop exporting PS1 from the bash activator so child processes do not inherit shell prompt state. (:issue:3158)

• Handle CYGWIN/MSYS/MINGW path conversions in fish activation script - by user::LuNoX. (:issue:3160)

---

v21.4.2 (2026-05-31)

---

Bugfixes - 21.4.2
