Changes from 2.3.0 to 2.3.1

  • Temporarily disable AVX512 support in C-Blosc2 for wheels built by CI until run-time detection works properly.

Changes from 2.2.9 to 2.3.0

  • Require at least Cython 3 for building. Using previous versions worked but error handling was not correct (wheels were being built with Cython 3 anyway).

  • New NDArray.to_cframe() method and blosc2.ndarray_from_cframe() function for serializing and deserializing NDArrays to/from contiguous in-memory frames. Thanks to Francesc Alted.

  • Add an optional offset argument to blosc2.schunk.open(), to access super-chunks stored in containers like HDF5. Thanks to Ivan Vilata.

  • Assorted minor fixes to the blocksize/blockshape computation algorithm, avoiding some cases where it resulted in values exceeding maximum limits. Thanks to Ivan Vilata.

  • Updated to latest C-Blosc2 2.11.2. It adds AVX512 support for the bitshuffle filter, fixes ARM and Raspberry Pi compatibility and assorted issues.

  • Add python-blosc2 package definition for Guix. Thanks to Ivan Vilata.
