Hello, The source packages and binaries got numpy 1.9.0 beta 2 have just been uploaded to sourceforge. https://sourceforge.net/projects/numpy/files/NumPy/1.9.0b2 1.9.0 will be a new feature release supporting Python 2.6 - 2.7 and 3.2 - 3.4. Unfortunately we have disabled the new __numpy_ufunc__ feature for overriding ufuncs in subclasses for now. There are still some unresolved issues with its behavior regarding python operator precedence and subclasses. If you have a stake in the issue please read Pauli's summary of the remaining issues: http://mail.scipy.org/pipermail/numpy-discussion/2014-July/070737.html When the issues are resolved to everyones satisfaction we hope to enable the feature for 1.10 in its final form. We have restored the indexing edge case that broke matplotlib with numpy 1.9.0 beta 1 but some of the other test failures in other packages are deemed bugs in their code and not reasonable to support in numpy anymore. Most projects have fixed the issues in their latest stable or development versions. Depending on how bad the broken functionality is you may need to update your third party packages when updating numpy to 1.9.0b2. An attempt was made to update the windows binary toolchain to the latest mingw/mingw64 version and an up to date ATLAS version but this turned up a few ugly test failures. Help in resolving these issues is appreciated, no core developer has Windows debugging experience. Please see this issue for details: https://github.com/numpy/numpy/issues/4909 The changelog is mostly the same as in beta1. Please read it carefully there have been many small changes that could affect your code. 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. Source tarballs, windows installers and release notes can be found at https://sourceforge.net/projects/numpy/files/NumPy/1.9.0b2 Cheers, Julian Taylor
