Release 0.1.1

Initial release

python-blosc2 aims to leverage the new C-Blosc2 API so as to support super-chunks, serialization and all the features introduced in C-Blosc2. This is work in process and will be done incrementally in future releases.

Note: python-blosc2 is meant to be backward compatible with python-blosc data. That means that it can read data generated with python-blosc, but the opposite is not true (i.e. there is no forward compatibility).

Changes from python-blosc to python-blosc2

• The functions compress_ptr and decompress_ptr
  are replaced by pack and unpack since
  Pickle protocol 5 comes with out-of-band data.

• The function pack_array is equivalent to pack,
  which accepts any object with attributes itemsize
  and size.

• On the other hand, the function unpack doesn't
  return a numpy array whereas the unpack_array
  builds that array.

• The blosc.NOSHUFFLE is replaced
  by the blosc2.NOFILTER, but for backward
  compatibility blosc2.NOSHUFFLE still exists.

• A bytearray or NumPy object can be passed to
  the blosc2.decompress function to store the
  decompressed data.
