NumPy 1.26.1 is a maintenance release that fixes bugs and regressions
discovered after the 1.26.0 release. In addition, it adds new functionality for
detecting BLAS and LAPACK when building from source. The 1.26.release series is
the last planned minor release series before NumPy 2.0. The Python versions
supported by this release are 3.9-3.12.

- Improved detection of BLAS and LAPACK libraries for meson builds
- Pickle compatibility with the upcoming NumPy 2.0.

``numpy._core`` submodule stubs
-------------------------------

``numpy._core`` submodule stubs were added to provide compatibility with
pickled arrays created using NumPy 2.0 when running Numpy 1.26.
