I'm pleased to announce the availability of the first release candidate of
NumPy 1.6.2.  This is a maintenance release. Due to the delay of the NumPy
1.7.0, this release contains far more fixes than a regular NumPy bugfix
release.  It also includes a number of documentation and build improvements.

Sources and binary installers can be found at

Please test this release and report any issues on the numpy-discussion
mailing list.
