NumPy 1.19.2 released
by Charles R Harris Sept. 10, 2020

Sept. 10, 2020

Hi All, On behalf of the NumPy team I am pleased to announce that NumPy 1.19.2 has been released. This release fixes several bugs, prepares for the upcoming Cython 3.x release. and pins setuptools to keep distutils working while upstream modifications are ongoing. The aarch64 wheels are built with the latest manylinux2014 release that fixes the problem of differing page sizes used by different Linux distros. There is a known problem with Windows 10 version=2004 and OpenBLAS svd that we are trying to debug. If you are running that Windows version you should use a NumPy version that links to the MKL library, earlier Windows versions are fine. This release supports Python 3.6-3.8. Downstream developers should use Cython >= 0.29.21 when building for Python 3.9 and Cython >= 0.29.16 when building for Python 3.8. OpenBLAS >= 3.7 is needed to avoid wrong results on the Skylake architecture. The NumPy Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.19.2/>, source archives, release notes, and wheel hashes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.19.2>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. *Contributors* A total of 8 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - Charles Harris - Matti Picus - Pauli Virtanen - Philippe Ombredanne + - Sebastian Berg - Stefan Behnel + - Stephan Loyd + - Zac Hatfield-Dodds *Pull requests merged* A total of 9 pull requests were merged for this release. - #16959: TST: Change aarch64 to arm64 in travis.yml. - #16998: MAINT: Configure hypothesis in ``np.test()`` for determinism,... - #17000: BLD: pin setuptools < 49.2.0 - #17015: ENH: Add NumPy declarations to be used by Cython 3.0+ - #17125: BUG: Remove non-threadsafe sigint handling from fft calculation - #17243: BUG: core: fix ilp64 blas dot/vdot/... for strides > int32 max - #17244: DOC: Use SPDX license expressions with correct license - #17245: DOC: Fix the link to the quick-start in the old API functions - #17272: BUG: fix pickling of arrays larger than 2GiB Cheers, Charles Harris

ANN: python-blosc 1.9.2 released!
by Francesc Alted Sept. 9, 2020

Sept. 9, 2020

============================= Announcing python-blosc 1.9.2 ============================= What is new? ============ This is a maintenance release to better support recent versions of Python (3.8 and 3.9). Also, and due to the evolution of modern CPUs, the number of default threads has been raised to 8 (from 4). Finally, zero-copy decompression is now supported by allowing bytes-like input. Thanks to Lehman Garrison. For more info, you can have a look at the release notes in: https://github.com/Blosc/python-blosc/blob/master/RELEASE_NOTES.rst More docs and examples are available in the documentation site: http://python-blosc.blosc.org What is it? =========== Blosc (http://www.blosc.org) is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc works well for compressing numerical arrays that contain data with relatively low entropy, like sparse data, time series, grids with regular-spaced values, etc. python-blosc (http://python-blosc.blosc.org/) is the Python wrapper for the Blosc compression library, with added functions (`compress_ptr()` and `pack_array()`) for efficiently compressing NumPy arrays, minimizing the number of memory copies during the process. python-blosc can be used to compress in-memory data buffers for transmission to other machines, persistence or just as a compressed cache. There is also a handy tool built on top of python-blosc called Bloscpack (https://github.com/Blosc/bloscpack). It features a command line interface that allows you to compress large binary data files on-disk. It also comes with a Python API that has built-in support for serializing and deserializing Numpy arrays both on-disk and in-memory at speeds that are competitive with regular Pickle/cPickle machinery. Sources repository ================== The sources and documentation are managed through github services at: http://github.com/Blosc/python-blosc ---- **Enjoy data!** -- The Blosc Development Team
