NumPy 1.16.3 Release Notes¶
The NumPy 1.16.3 release fixes bugs reported against the 1.16.2 release, and also backports several enhancements from master that seem appropriate for a release series that is the last to support Python 2.7. The wheels on PyPI are linked with OpenBLAS v0.3.4+, which should fix the known threading issues found in previous OpenBLAS versions.
Downstream developers building this release should use Cython >= 0.29.2 and, if using OpenBLAS, OpenBLAS > v0.3.4.
The most noticeable change in this release is that unpickling object arrays
*.npz files now requires an explicit opt-in.
This backwards incompatible change was made in response to
Covariance in random.mvnormal cast to double¶
This should make the tolerance used when checking the singular values of the covariance matrix more meaningful.
