Changelog

Sourced from tox's changelog.

Features - 4.46.0

• Add architecture (ISA) awareness to Python discovery. tox now propagates the machine field (e.g. arm64, x86_64) from :pypi:virtualenv's interpreter info — derived from :func:python:sysconfig.get_platform — through the Python specification, validation, and journal. This allows selecting a Python interpreter by CPU architecture via :ref:base_python (e.g. cpython3.12-64-arm64) and ensures tox validates the running interpreter's architecture matches the requested one. Requires virtualenv >= 20.39 - by :user:rahuldevikar. (:issue:3069)
• Add env_base TOML sections for named environment templates that generate multiple environments from factor combinations via Cartesian product -- by :user:gaborbernat. (:issue:3817)

Bug fixes - 4.46.0

• Drop chardet dependency and use BOM detection with locale fallback for requirements file decoding, matching pip's own approach - by :user:gaborbernat. (:issue:3818)
• Allow --help to render even when the configuration file is malformed or missing - by :user:gaborbernat. (:issue:3819)

v4.45.0 (2026-02-23)

---

Features - 4.45.0

• Enhance tox schema command: add x-taplo metadata for IDE integration, product dict support for env_list, handle int and PythonConstraints types, fix $schema draft-07 URI, and add schema freshness test. Add tox.toml to SchemaStore catalog for automatic IDE validation - by :user:gaborbernat. (:issue:1388)

Bug fixes - 4.45.0

• Add redirects for old documentation URLs that broke after the Diataxis restructure (e.g. /config.html -> /reference/config.html, /example/general.html -> /index.html) using sphinx-reredirects - by :user:gaborbernat. (:issue:3806)
• Fix cross-section substitution {[section]key} resolving to a literal unresolved reference instead of empty string when the referenced value contains only factor-conditional lines and no factors match the requesting environment - by :user:Fridayai700. (:issue:3809)
• Fix circular dependency in environment_variables when set_env references {env_site_packages_dir} or similar lazy constants, causing RecursionError silently caught as "could not find python interpreter" - by :user:gaborbernat. (:issue:3816)
