This is documentation for an old release of NumPy (version 1.18). Read this page in the documentation of the latest stable release (version 2.2).
NumPy 1.6.2 Release Notes¶
This is a bugfix release in the 1.6.x series. Due to the delay of the NumPy 1.7.0 release, this release contains far more fixes than a regular NumPy bugfix release. It also includes a number of documentation and build improvements.
