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)
