Purpose: pyenv lets users switch between multiple Python versions.
Version selection: It supports global per-user and per-project Python versions, plus overrides through an environment variable.
Distributions: It supports CPython, PyPy, Stackless Python, Jython, and other Python distributions.
Shims: It intercepts Python commands through shim executables added to PATH and routes them to the selected installation.
Multiple versions: Users can make multiple installed Python versions available at once, including for cross-version testing with tox.
Builds: Most pyenv-provided Python releases are built from source during installation, and Python build dependencies must be installed first.
Virtual environments: pyenv does not manage virtual environments itself; the project points users to virtualenv or the pyenv-virtualenv plugin.
Plugins: The project supports extending and customizing functionality with plugins.
Installation: The README documents installation on Linux/Unix and macOS, including a shell installer, Git checkout, and Homebrew.
Windows support: The project says it does not officially support Windows and does not work outside Windows Subsystem for Linux; it recommends the pyenv-win fork for native Windows Python versions.
Security: The v2.8.0 changelog lists a fix for CVE-2026-68939 involving glob character handling in .python-version.
License: The repository identifies pyenv as MIT licensed.
