Changelog

Sourced from tox's changelog.

Bug fixes - 4.50.1

• Detect and suggest normalized environment names when users specify dotted Python versions (e.g., py3.10-lint) that match existing environments with compact notation (e.g., py310-lint), preventing silent fallback to base [testenv] configuration - by :user:gaborbernat. (:issue:3877)

v4.50.0 (2026-03-17)

---

Features - 4.50.0

• Add interrupt_post_commands option to run cleanup commands even after SIGINT - by :user:gaborbernat. (:issue:3858)
• Add factor['NAME'] and env['VAR'] subscript syntax for conditional expressions, enabling checks of factors with non-identifier names like factor['3.14']. Add env_name variable to check the full environment name in conditions. (:issue:3880)

Bug fixes - 4.50.0

• Fix multiple manpage issues: remove duplicate header/author/copyright sections, set project in Sphinx config, and compile the manpage to troff format at wheel-build time instead of shipping raw RST source - by :user:gaborbernat. (:issue:3878)

Improved documentation - 4.50.0

• Document how to reference the built package path in commands via TOX_PACKAGE - by :user:rahuldevikar (:issue:3862)
• Fix broken TOML examples missing extend = true on conditional replacements inside lists, fix incorrect ref of path in raw reference docs, and add a test that validates all doc config examples - by :user:gaborbernat (:issue:3875)
