Announcing Python-Blosc2 2.3.1
==============================

The new minor release 2.3 adds methods to handle NDArrays serialized into
memory frames, and allows opening super-chunks stored in container files (like
HDF5) by their offset.  C-Blosc2 is updated to the latest stable version,
which provides support for AVX512 (temporarily disabled in wheels) and fixes
compatibility with ARM platforms (e.g. Raspberry Pi).  Cython 3 is now
required for building, and other minor fixes and additions are included as
well.

For more info, you can have a look at the release notes in:

More docs and examples are available in the documentation site:

What is it?
-----------

Python-Blosc2 is a Python package that wraps C-Blosc2, the newest version of
the Blosc compressor.  Currently Python-Blosc2 already reproduces the API of
Python-Blosc (https://github.com/Blosc/python-blosc), so the former can be
used as a drop-in replacement for the later. However, there are a few
exceptions for full compatibility:

Python-Blosc2 comes with NDArray support, which is a new Python class that
allows to create multi-dimensional arrays of compressed data.  NDArray
follows the same (or very similar) API as NumPy arrays, so it can be used
as a drop-in replacement.  See the documentation for more details:
https://www.blosc.org/python-blosc2/reference/ndarray_api.html
