Release Notes

wntrblm/nox (nox)

v2026.10.20

Compare Source

Parallel mode no longer prints an "experimental" banner, and sessions can check
session.parallel to see if they run in a parallel worker. A new rattler
backend uses py-rattler (install with the nox[rattler] extra), so you can
request fast conda-style environments in a /// script block. Python versions
read from classifiers now include free-threaded builds when the free-threading
classifier is present, and are deduplicated. A single-argument
@nox.parametrize now accepts ranges and other iterators, and the rattler
backend loads config from the default locations. The GitHub Action now
defaults to Python 3.11-3.15. This release also fixes several bugs in script
mode, option handling, and tox-to-nox.
