Features - 4.42.0

• Platform-dependent commands can now be specified using factor syntax without requiring the platform name in the environment name. The current platform (sys.platform value like linux, darwin, win32) is automatically available as an implicit factor, allowing configurations like linux: pytest in INI or factor.linux in TOML conditional expressions to work in any environment. Additionally, TOML configurations can now use factor.NAME in conditional expressions to filter settings based on environment name factors, achieving feature parity with INI's factor system - by :user:gaborbernat. (:issue:2092)
• Add {env_site_packages_dir_plat} / {envsitepackagesdir_plat} substitution that returns the platform-specific (platlib) site-packages directory. On some Linux distributions (Fedora, RHEL) this resolves to lib64 instead of lib, which is no longer symlinked since virtualenv 20.x - by :user:gaborbernat. (:issue:2302)
• External packaging environments (package = external) now only run their build commands once per session, reusing the built package for all test environments that depend on them - by :user:gaborbernat. (:issue:2729)
• Add default_base_python configuration key to specify a fallback Python interpreter when no Python factor or explicit base_python is defined. This allows projects to pin a default Python version for reproducibility across different machines without conflicting with pyXY factor-named environments - by :user:gaborbernat. (:issue:2846)
• CLI options added by plugins listed in requires are now accepted during provisioning instead of failing with "unrecognized arguments" - by :user:gaborbernat. (:issue:2935)
• Warn about unused configuration keys during tox run -v - by :user:gaborbernat. (:issue:3188)
• Improve towncrier changelog structure with more granular categories: breaking, deprecation, feature, bugfix, doc, packaging, contrib, and misc - by :user:gaborbernat. (:issue:3200)
• Add --skip-env-install CLI flag to skip dependency and package installation, allowing reuse of existing environments when offline or when installation is unnecessary - by :user:gaborbernat. (:issue:3310)
• Add recreate_commands configuration option to run cleanup commands (e.g. clearing external caches like pre-commit) before the environment directory is removed during recreation (-r) - by :user:gaborbernat. (:issue:3423)
• Environments with unavailable runners (missing plugins) are now gracefully skipped instead of causing a fatal error, shown with status "NOT AVAILABLE". If such an environment is explicitly requested with -e, a clear error message is shown indicating which runner is missing and that the plugin may not be installed. Unavailable environments in the configuration don't cause the overall run to fail - by :user:gaborbernat. (:issue:3504)
• Add open-ended range expansion in generative env lists — py3{9-} expands up to the latest supported CPython minor version and py3{-13} expands down to the oldest supported one, both hardcoded at release time per the Python release cycle <https://devguide.python.org/versions/>_ - by :user:gaborbernat. (:issue:3583)
• Add --no-capture (-i) CLI flag to disable output capture, allowing interactive programs like Python REPL to access the terminal directly. When enabled, subprocess inherits parent console handles instead of pipes, fixing issues where terminal APIs (e.g., querying console dimensions) fail on pipe handles. Mutually exclusive with --result-json and parallel mode - by :user:gaborjbernat. Fixes :issue:3635. (:issue:3635)
• Add virtualenv_spec configuration key that allows pinning a specific virtualenv version per environment (e.g. virtualenv_spec = "virtualenv<20.22.0"). When set, tox bootstraps the specified version in an isolated environment and drives it via subprocess, enabling environments targeting Python versions incompatible with the installed virtualenv - by :user:gaborbernat. (:issue:3656)

Bug fixes - 4.42.0

• Suppress BrokenPipeError during backend teardown when interrupted, preventing traceback spam during KeyboardInterrupt - by :user:gaborjbernat. Fixes :issue:2660. (:issue:2660)
• Factor-specific multiline commands using backslash continuation (\) no longer leak continuation lines into environments that don't match the factor - by :user:gaborbernat. (:issue:2912)
