NumPy 2.1.3 is a maintenance release that fixes bugs and regressions
discovered after the 2.1.2 release. This release also adds support
for free threaded Python 3.13 on Windows.
The Python versions supported by this release are 3.10-3.13.
Improvements
Fixed a number of issues around promotion for string ufuncs with
StringDType arguments. Mixing StringDType and the fixed-width DTypes
using the string ufuncs should now generate much more uniform
results.
This is a walkthrough of the NumPy 2.1.0 release on Linux, modified for
building with GitHub Actions and cibuildwheels and uploading to the
anaconda.org staging repository for NumPy <https://anaconda.org/multibuild-wheels-staging/numpy>_.
The commands can be copied into the command line, but be sure to replace 2.1.0
by the correct version. This should be read together with the
:ref:general release guide <prepare_release>.
Facility preparation
Before beginning to make a release, use the requirements/*_requirements.txt files to
ensure that you have the needed software. Most software can be installed with
pip, but some will require apt-get, dnf, or whatever your system uses for
software. You will also need a GitHub personal access token (PAT) to push the
documentation. There are a few ways to streamline things:
Git can be set up to use a keyring to store your GitHub personal access token.
Search online for the details.
You can use the keyring app to store the PyPI password for twine. See the
online twine documentation for details.
Prior to release
Add/drop Python versions
When adding or dropping Python versions, three files need to be edited:
.github/workflows/wheels.yml # for github cibuildwheel
tools/ci/cirrus_wheels.yml # for cibuildwheel aarch64/arm64 builds
pyproject.toml # for classifier and minimum version check.
Make these changes in an ordinary PR against main and backport if necessary.
Add [wheel build] at the end of the title line of the commit summary so
that wheel builds will be run to test the changes. We currently release wheels
for new Python versions after the first Python rc once manylinux and
cibuildwheel support it. For Python 3.11 we were able to release within a week
of the rc1 announcement.
Backport pull requests
Changes that have been marked for this release must be backported to the
maintenance/2.1.x branch.
