Changelog

Sourced from tox's changelog.

Bug fixes - 4.48.1

• Command-type configuration values like list_dependencies_command can now be referenced in TOML using the structured {replace = "ref"} syntax. The reference automatically extracts the command's argument list for compatibility with TOML's list[list[str]] structure - by :user:gaborbernat. (:issue:3830)

Improved documentation - 4.48.1

• Replace archived 31z4/tox Docker image recommendation with instructions for building your own image using the official Python base image and uv - by :user:rahuldevikar. (:issue:3855)

---

v4.48.0 (2026-03-05)

---

Features - 4.48.0

• Add --format flag (ini, json, toml) and -o/--output-file to the config command for machine-readable output with native types. JSON and TOML use the same key structure as tox.toml (env.<name> for environments, tox for core) and get syntax-highlighted on stdout - by :user:gaborbernat. (:issue:3854)

Improved documentation - 4.48.0

• Add fail_fast to the configuration reference documentation - by :user:rahuldevikar. (:issue:578)

v4.47.3 (2026-03-04)
