📝 Walkthrough

Walkthrough

Adds Python 3.14 to the project support matrix: updates pyproject Python range, adds 3.14 to Nox and GitHub Actions unit test matrices, updates Linux install docs, and notes 3.14 support in the changelog; also reformats a ruff per-file-ignores entry.

Changes

Python 3.14 Support & Version Documentation

Layer / File(s)	Summary
Dependency Declaration pyproject.toml	project.requires-python changed from >=3.10,<3.14 to >=3.10,<3.15. Reformat tool.ruff.lint.per-file-ignores["modelopt/torch/kernels/quantization/gemm/*"] into a multi-line list keeping the same rule codes (N803, N806, E731).
Test Infrastructure noxfile.py	@nox.session(python=[...]) for the unit session adds "3.14" to the list.
CI Matrix .github/workflows/unit_tests.yml	Adds an include matrix entry nox_session: "unit-3.14(torch_211, tf_latest)" with python_version: "3.14" to the multi-version job.
Installation Documentation docs/source/getting_started/_installation_for_Linux.rst	Updates Linux Python requirement from >=3.10,<3.14 to >=3.10,<3.15.
Release Documentation CHANGELOG.rst	Adds a 0.44 misc bullet noting Python 3.14 installation support (basic unit tests verified), with production default remaining Python 3.12 and Python 3.10 to be dropped next release.

22-30: ⚡ Quick win

Add a Python 3.14 Trove classifier to match declared support.

requires-python now includes 3.14, but the classifiers stop at 3.13. Aligning both improves package metadata accuracy on indexes/tools.

Proposed change

 classifiers = [
     "Programming Language :: Python :: 3",
     "Programming Language :: Python :: 3.10",
     "Programming Language :: Python :: 3.11",
     "Programming Language :: Python :: 3.12",
     "Programming Language :: Python :: 3.13",
+    "Programming Language :: Python :: 3.14",
     "Intended Audience :: Developers",
     "Intended Audience :: Science/Research",
     "Topic :: Scientific/Engineering :: Artificial Intelligence",
 ]

Inline comments:
In `@CHANGELOG.rst`:
- Line 63: Update the release note sentence (the line containing "Add
installation support for Python 3.14. Only basic unit tests are verified for
now. Production usage is still default to Python 3.12. Python 3.10 support will
be dropped in the next release.") to clearer, grammatical wording — for example:
"Add installation support for Python 3.14; only basic unit tests have been
verified so far. Production builds will continue to target Python 3.12, and
Python 3.10 support will be dropped in the next release." Replace the original
sentence with this tightened phrasing.
