Changelog

Sourced from tox's changelog.

Features - 4.57.0

• Support debug (Py_DEBUG) interpreters the way free-threaded builds are already handled. The py313d and py313td factors select a debug build, a base_python pointing at one matches those factors and conflicts with factors that lack the suffix, and a debug build gets its own d-tagged wheel build environment - by :user:chuenchen309. (:issue:3986)

Bug fixes - 4.57.0

• Keep the free-threaded t suffix when deriving the base python spec from a path, so a base_python pointing at a free-threaded interpreter matches py313t factors and conflicts with factors that lack the suffix - by :user:chuenchen309. (:issue:3986)

v4.56.4 (2026-07-08)

---

Bug fixes - 4.56.4

• Discover debug (Py_DEBUG) interpreters set as base_python, such as Debian's python3.13-dbg - the spec was misread as a machine named dbg and no interpreter matched. Requires python-discovery>=1.4.4 - by :user:gaborbernat. (:issue:3977)

---

v4.56.3 (2026-07-08)

---

Bug fixes - 4.56.3

• Stop double-closing the child pty file descriptor when running under a tty, which could race a parallel run that had reused the freed descriptor number and cause intermittent Bad file descriptor/Input/output error failures - by :user:apoorvdarshan. (:issue:3975)

---

v4.56.2 (2026-07-07)

---

Bug fixes - 4.56.2

• Fix a batch of latent defects found in a codebase audit:

  • stop duplicating --extra-index-url when a merged requirements line repeats an already-seen index;
  • render --no-binary/--only-binary as comma-joined strings instead of leaking the internal set into the pip command line;
  • report a clear error instead of IndexError for a bare one-argument flag (-c, -r, -f, -e) in
