Release 2.7.0

Changes from 2.6.2 to 2.7.0

• Updated to latest C-Blosc2 2.15.0.

• Deprecated LazyExpr.evaluate().

• Fixed _check_rc function. See #187.

Release 2.6.2

Changes from 2.6.1 to 2.6.2

• Protection when platforms have just one CPU. This caused the
  internal number of threads to be 0, producing a division by zero.

• Updated to latest C-Blosc2 2.14.3.

Release 2.6.1

Changes from 2.6.0 to 2.6.1

• Updated to latest C-Blosc2 2.14.1. This was necessary to be able to
  load dynamics plugins on Windows.

Release 2.6.0

Changes from 2.5.1 to 2.6.0

• [EXP] New evaluation engine (based on numexpr) for NDArray instances.
  Now, you can evaluate expressions like a + b + 1 where a and b
  are NDArray instances. This is a powerful feature that allows for
  efficient computations on compressed data. See this example to see how this works.
  Thanks to @omaech for her help in the pow function.

• As a consequence of the above, there are many new functions to operate with
  NDArray instances. See the function section in NDArray API for more information.

• Support for NumPy 2.0.0 is here! Now, the wheels are built with NumPy 2.0.0rc1.
  Please tell us in case you see any issues with this new version.

• Add **kwargs to load_tensor() function. This allows to pass additional parameters
  to the deserialization function. Thanks to @jasam-sheja.

• Fix vlmeta.to_dict() not honoring tuple encoding. Thanks to @ivilata.

• Check that chunks/blocks computation does not allow a 0 in blocks. Thanks to @ivilata.

• Many improvements in ruff rules and others. Thanks to @DimitriPapadopoulos.

• Remove printing large arrays in notebooks (they use too much RAM in recent versions of Jupyter notebook).

• Updated to latest C-Blosc2 2.14.0.

Release 2.5.1

Changes from 2.5.0 to 2.5.1

• Updated to latest C-Blosc2 2.13.1.

• Fixed bug in b2nd.h.

Changes from 2.4.0 to 2.5.0

• Updated to latest C-Blosc2 2.13.0.

• Added the filter INT_TRUNC for integer truncation.

• Added some optimizations for zstd.

• Now the grok library is initialized when loading the
  plugin from C-Blosc2.

• Improved doc.

• Support for slices in blosc2.get_slice_nchunks() when using SChunk
  objects.

Release 2.4.0

Changes from 2.3.2 to 2.4.0

• Updated to latest C-Blosc2 2.12.0.

• Added blosc2.get_slice_nchunks() to get array of chunk
  indexes needed to get a slice of a Blosc2 container.

• Added grok codec plugin.

• Added imported target with pkg-config to support windows.

Release 2.3.2

Changes from 2.3.1 to 2.3.2

• Support for pathlib.Path objects in all the places where urlpath is
  used (e.g. blosc2.open()). Thanks to Marta Iborra.

• Included docs for SChunk.fill_special() and NDArray.dtype. Thanks
  to Francesc Alted.

• Upgrade to latest C-Blosc2 2.11.3. It fixes a bug preventing the use of
  typesize > 255 in frames. Now you can use a typesize up to 2**31-1.

Release 2.3.1

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.

Release 2.2.9

Changes from 2.2.8 to 2.2.9

• Support for specifying (plugable) tuner parameters in cparams. Thanks to
  Marta Iborra.

• Re-add support for Python 3.8. Although we don't provide wheels for it,
  support is there (although it requires compilation time).

• Avoid duplicate iteration over the same dict. Thanks to Dimitri Papadopoulos.

• Fix different issues with f-strings. Thanks to Dimitri Papadopoulos.

Release 2.2.8

• Binary wheels for forthcoming Python 3.12 are available!

• Different improvements suggested by refurb and pyupgrade.
  Thanks to Dimitri Papadopoulos.

• Updated to latest C-Blosc2 2.10.4.
