Hello, I'm happy to announce the fist beta release of Numpy 1.9.0. 1.9.0 will be a new feature release supporting Python 2.6 - 2.7 and 3.2 - 3.4. Due to low demand windows binaries for the beta are only available for Python 2.7, 3.3 and 3.4. Please try it and report any issues to the numpy-discussion mailing list or on github. The 1.9 release will consists of mainly of many small improvements and bugfixes. The highlights are: * Addition of __numpy_ufunc__ to allow overriding ufuncs in ndarray subclasses. Please note that there are still some known issues with this mechanism which we hope to resolve before the final release (e.g. #4753) * Numerous performance improvements in various areas, most notably indexing and operations on small arrays are significantly faster. Indexing operations now also release the GIL. * Addition of nanmedian and nanpercentile rounds out the nanfunction set. The changes involve a lot of small changes that might affect some applications, please read the release notes for the full details on all changes: https://github.com/numpy/numpy/blob/maintenance/1.9.x/doc/release/1.9.0-note... Please also take special note of the future changes section which will apply to the following release 1.10.0 and make sure to check if your applications would be affected by them.
