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

.
