Deprecations and Removals - 21.0.0

• The Python discovery logic has been extracted into a standalone python-discovery package on PyPI (documentation <https://python-discovery.readthedocs.io/>_) and is now consumed as a dependency. If you previously imported discovery internals directly (e.g. from virtualenv.discovery.py_info import PythonInfo), switch to from python_discovery import PythonInfo. Backward-compatibility re-export shims are provided at virtualenv.discovery.py_info, virtualenv.discovery.py_spec, and virtualenv.discovery.cached_py_info, however these are considered unsupported and may be removed in a future release - by :user:gaborbernat. (:issue:3070)

v20.39.1 (2026-02-25)

---

Features - 20.39.1

• Add support for creating virtual environments with RustPython - by :user:elmjag. (:issue:3010)

---

v20.39.0 (2026-02-23)

---

Features - 20.39.0

• Automatically resolve version manager shims (pyenv, mise, asdf) to the real Python binary during discovery, preventing incorrect interpreter selection when shims are on PATH - by :user:gaborbernat. (:issue:3049)
• Add architecture (ISA) awareness to Python discovery — users can now specify a CPU architecture suffix in the --python spec string (e.g. cpython3.12-64-arm64) to distinguish between interpreters that share the same version and bitness but target different architectures. Uses sysconfig.get_platform() as the data source, with cross-platform normalization (amd64 ↔ x86_64, aarch64 ↔ arm64). Omitting the suffix preserves existing behavior - by :user:rahuldevikar. (:issue:3059)
