- Update to 1.2.4
  - Updated to c-blosc 1.4.0.  This added support for non-Intel
    architectures, most specially those not supporting unaligned access.

- Update to 1.2.3
  - Updated to c-blosc 1.3.5.  This removed a 'pointer from integer
    without a cast' compiler warning due to a bad macro definition.
- Update to 1.2.2
  - Updated to c-blosc 1.3.4.  This fixed a false buffer overrun
    condition.  This bug made c-blosc (and hence python-blosc) to fail,
    even if the failure was not real.
- Update to 1.2.1
  - Updated to c-blosc 1.3.3.
  - Added a new `cname2clib` map for programatically determine the library
    associated to a compressor.
  - New `get_clib(cbuffer)` that tells which compression library format
    has been used to created the compressed `cbuffer`.
- Update to 1.2.0
  - This release adds support for the multiple compressors added in Blosc
    1.3 series.
  - Added new `cname` parameter in compression functions like
    `compress()`, `compress_ptr()` and `pack_array()`.
  - Added a new utility function named `compressor_list()` that returns
    the list of compressors supported in the Blosc build.
  - Added 'bench/compress_ptr.py' for comparing times of the different
    compressors in Blosc and NumPy.
- Update to 1.1.0
  - Added new `compress_ptr` and `decompress_ptr` functions that allows to
    compress and decompress from/to a data pointer.  These are low level
    calls and user must make sure that the pointer data area is safe.
  - Since Blosc (the C library) already supports to be installed as an
    standalone library (via cmake), it is also possible to link
    python-blosc against a system Blosc library.
  - The Python calls to Blosc are now thread-safe (another consequence of
    recent Blosc library supporting this at C level).
  - Many checks on types and ranges of values have been added.  Most of
    the calls will now complain when passed the wrong values.
  - Docstrings are much improved. Also, Sphinx-based docs are available
    now.
- Update to 1.0.6
  - Fix compile error with msvc compilers.  Thanks to Christoph Gohlke.
- Update to 1.0.5
  - Upgraded to latest Blosc 1.1.4.
  - Better handling of condition errors, and improved memory releasing in
    case of errors (thanks to Valentin Haenel and Han Genuit).
  - Better handling of types (should compile without warning now, at least
    with GCC).
- Update to 1.0.4
  - Optimized the amount of data copied during compression (using
    _PyBytes_Resize() now instead of old PyBytes_FromStringAndSize()).
    This leads to improvements in compression speed ranging from 1.2x for
    highly compressible chunks up to 7x for mostly uncompressible data.
    Thanks to Valentin Haenel for this nice contribution.
- Use external blosc library.  The internal one builds a bad version
  of zlib.
