Hi,
This is a bugfix release, with some minor optimizations. We further
improved the
correct chaining of *string* lazy expressions (to allow operands with more
diverse data types). In addition, both indexing and where expressions are
now
supported within *string* lazy expressions. Finally, casting rules have
been improved to be more consistent with NumPy.
You can think of Python-Blosc2 3.x as an extension of NumPy/numexpr that:
- Can deal with ndarrays compressed using first-class codecs & filters.
- Performs many kind of math expressions, including reductions, indexing...
- Supports broadcasting operations.
- Supports NumPy ufunc mechanism: mix and match NumPy and Blosc2
computations.
- Integrates with Numba and Cython via UDFs (User Defined Functions).
- Adheres to modern NumPy casting rules way better than numexpr.
- Supports linear algebra operations (like ``blosc2.matmul()``).
Install it with::
pip install blosc2 --update # if you prefer wheels
conda install -c conda-forge python-blosc2 mkl # if you prefer conda
and MKL
For more info, you can have a look at the release notes in:

Have fun!
