Changelog

Sourced from tox's changelog.

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)

---

v4.49.1 (2026-03-09)

---

Bug fixes - 4.49.1

• Break deadlock in execution interrupt chain that caused ~18 flaky timeout failures across 9 tests on Windows/macOS CI
  • by :user:gaborbernat. (:issue:3869)

---

v4.49.0 (2026-03-06)

---

Features - 4.49.0

• Add {factor:label} substitution for TOML configs -- factor groups in product matrices and env_base factors can now be labeled with single-key dicts (e.g., {ecosystem = ["oci", "python"]}), enabling {factor:ecosystem} in any string value (descriptions, commands, etc.) to resolve to the active factor. Plain lists automatically get positional labels ({factor:0}, {factor:1}, ...) - by :user:gaborbernat. (:issue:3860) (:issue:3860)

Bug fixes - 4.49.0
