# NumPy 1.15.2 Release Notes

This is a bugfix release for bugs and regressions reported following the 1.15.1 release.

- The matrix PendingDeprecationWarning is now suppressed in pytest 3.8.

- The new cached allocations machinery has been fixed to be thread safe.

- The boolean indexing of subclasses now works correctly.

- A small memory leak in PyArray_AdaptFlexibleDType has been fixed.

The Python versions supported by this release are 2.7, 3.4-3.7. The wheels are linked with OpenBLAS v0.3.0, which should fix some of the linalg problems reported for NumPy 1.14.

## Compatibility Note

The NumPy 1.15.x OS X wheels released on PyPI no longer contain 32-bit binaries. That will also be the case in future releases. See #11625 for the related discussion. Those needing 32-bit support should look elsewhere or build from source.
