[dependabot]

Bumps the coredeps group with 2 updates in the /ci directory: numpy and netcdf4.

Updates numpy from 2.4.0 to 2.4.1

Release notes

Sourced from numpy's releases.

2.4.1 (Jan 10, 2026)

NumPy 2.4.1 Release Notes

The NumPy 2.4.1 is a patch release that fixes bugs discoved after the 2.4.0 release. In particular, the typo SeedlessSequence is preserved to enable wheels using the random Cython API and built against NumPy < 2.4.0 to run without errors.

This release supports Python versions 3.11-3.14

Changelog

Sourced from numpy's changelog.

This is a walkthrough of the NumPy 2.4.0 release on Linux, which will be the first feature release using the numpy/numpy-release <https://github.com/numpy/numpy-release>__ repository.

The commands can be copied into the command line, but be sure to replace 2.4.0 with 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, multiple config and CI files need to be edited in addition to changing the minimum version in pyproject.toml. Make these changes in an ordinary PR against main and backport if necessary. We currently release wheels for new Python versions after the first Python RC once manylinux and cibuildwheel support that new Python version.

Backport pull requests

Changes that have been marked for this release must be backported to the maintenance/2.4.x branch.

Updates netcdf4 from 1.7.3 to 1.7.4

Changelog

Sourced from netcdf4's changelog.

version 1.7.4 (tag v1.7.4rel)

• Make sure automatic conversion of character arrays <--> string arrays works for Unicode strings (issue #1440). (previously only worked correctly for encoding="ascii").
• Add netcdf plugins (blosc, zstd, bzip2) in wheels. Blosc plugin doesn't work in Windows wheels. Macos wheels now use conda provided libs. (PR #1450)
• Add windows/arm (PR #1453) and free-threaded python wheels (issue #1454). Windows wheels now use netcdf-c 4.9.3. WARNING: netcdf-c is not thread-safe and netcdf4-python does have internal locking so expect segfaults if you use netcdf4-python on multiple threads with free-threaded python. Users must exercise care to only call netcdf from a single thread.

version 1.7.3 (tag v1.7.3rel)

• Python 3.14 wheels (issue #1432)
• support os.PathLike arguments for Dataset.fromcdl and raise a FileNotFoundError if the cdl is missing and a FileExistsError if the nc file already exists (PR #1387)
• raise more informative error when trying to iterate or perform a membership operation on a Dataset (issue #1383)
• fix type hint for createEnumType (issue #1378)
• add python 3.13 to windows wheel builds (PR #1377)
• allow slicing of vlen and string variables with non-unitary strides (issue #1408).

version 1.7.2 (tag v1.7.2rel)

• add static type hints (PRs #1302, #1349)
• Expose nc_rc_set, nc_rc_get (via rc_set, rc_get module functions). (PR #1348)
• Add Variable.get_fill_value and allow fill_value='default' to set _FillValue attribute using default fill values. (issue #1374, PR #1375).
• Fix NETCDF3 endian error (issue #1373, PR #1355).

version 1.7.1 (tag v1.7.1rel)

• include nc_complex source code from v0.2.0 tag (instead of using submodule).
• add aarch64 wheels.

version 1.7.0 (tag v1.7.0rel)

• add support for complex numbers via auto_complex keyword to Dataset (PR #1295)
• fix for deprecated Cython DEF and IF statements using compatibility header with shims for unavailable functionality (PR #1277)
• use szip as the library name on Windows (PR #1304)
• add support for MS-MPI MPI_Message detection (PR #1305)
• fix for issue #1306 - surprising result when indexing vlen str with non-contiguous indices.
• Fix bug in set_collective introduced in PR #1277 (collective mode was always set).

version 1.6.5 (tag v1.6.5rel)

• fix for issue #1271 (mask ignored if bool MA assigned to uint8 var)
