# NumPy 1.18.4 Release Notes

This is the last planned release in the 1.18.x series. It reverts the `bool("0")` behavior introduced in 1.18.3 and fixes a bug in `Generator.integers`. There is also a link to a new troubleshooting section in the documentation included in the error message emitted when numpy import fails.

The Python versions supported in this release are 3.5-3.8. Downstream developers should use Cython >= 0.29.15 for Python 3.8 support and OpenBLAS >= 3.7 to avoid errors on the Skylake architecture.
