- Update to version 1.5.1

* License updated from MIT to BSD.

* Updated to C-Blosc 1.11.3.
- Update to version 1.5.0

* Added a new `blosc.set_releasegil()` function that allows to
release/acquire the GIL at will. See PR #116.
Thanks to Robert McLeod.

* Updated to C-Blosc 1.11.2.

* Added tests that detect possible memory leaks.
Thanks to Robert McLeod.
- Update to version 1.4.4

* Updated to C-Blosc 1.11.1. Fixes #115.
- Update to version 1.4.3

* Internal C-Blosc sources updated to 1.11.0. Among other things, this
updates the internal Zstd codec to version 1.0.0 (i.e. it is
officially apt for production usage!).
- Update to version 1.4.1

* Internal C-Blosc sources updated to 1.10.1. This fixes an outstanding issue
with the clang compiler. For details, see:
https://github.com/Blosc/bloscpack/issues/50.
- Update to version 1.4.0

* Internal C-Blosc sources updated to 1.10.0.

* Benchmarks updated for a Skylake processor (Xeon E3-1245 v5 AATT
3.50GHz).
- Update to version 1.3.3

* Internal C-Blosc sources updated to 1.9.3.

* C-Blosc do not segfaults anymore, so -O1 flag on Linux is not the
default anymore.

* SSE2 and AVX2 are now auto-discovered so the internal C-Blosc will be
compiled with maximum optimization on processors supporting them.
- Update to version 1.3.2

* Fixed the version of the include C-Blosc library (should be 1.8.1 not
1.8.2.dev).
- Update to version 1.3.1

* Use the -O1 flag for compiling the included C-Blosc sources on Linux.
This represents slower performance, but fixes the nasty issue #110.
Also, it prints a warning for using an external C-Blosc library.

* Internal C-Blosc version bumped to 1.8.1 for better compatibility
with gcc 5.3.1 in forthcoming Ubuntu Xenial.

* Added a protection to avoid using BITSHUFLE with C-Blosc < 1.8.0.

* Restored old symbols for backward compatibility with pre 1.3.0:
BLOSC_VERSION_STRING
BLOSC_VERSION_DATE
BLOSC_MAX_BUFFERSIZE
BLOSC_MAX_THREADS
BLOSC_MAX_TYPESIZE
However, these are considered deprecated and should be replaced by
libraries using python-blosc by the ones without the BLOSC_ prefix.
- Update to version 1.3.0

* Internal C-Blosc version bumped to 1.8.0. As consequence, support for
BITSHUFFLE is here. For activating it, just pass `blosc.BITSHUFFLE`
to the `shuffle` parameter of compression functions.

* Added a new `as_bytearray=False` parameter to the `decompress()` function
so that a mutable bytearray will be returned instead of a bytes one
(inmutable). PR #107. Thanks to Joe Jevnik.

* The \'__all__\' variable has been removed from the module. I consider
this good practice to avoid things like \"from blosc import
*\".

* For consistency, the next symbols have been renamed:
BLOSC_VERSION_STRING -> VERSION_STRING,
BLOSC_VERSION_DATE -> VERSION_DATE,
BLOSC_MAX_BUFFERSIZE -> MAX_BUFFERSIZE,
BLOSC_MAX_THREADS -> MAX_THREADS,
BLOSC_MAX_TYPESIZE -> MAX_TYPESIZE,

* The `typesize` parameter is set by default to 8 in compression
functions. This usually behaves well for 4-bytes typesizes too.
Nevertheless, it is advised to use the actual typesize.

* The maximum number of threads to use by default is set to 4 (less if
less cores are detected). Feel free to use more or less threads
depending on the resources you want to use for compression.
- Implement single-spec version.

- Update to version 1.2.8

* Updated to c-blosc v1.7.0. However, the new bitshuffle filter
has not been made public because recent reports indicate that
it seems too green for production.

* Support bytes-like objects that support the buffer interface
as input to compress and decompress. On Python 2.x this
includes unicode, on Python 3.x it doesn\'t. (#80 #94 AATTesc)

* Fix a memory leak in decompress. Added tests to catch memory
leaks. (#102 #103 #104 AATTsdvillal)

* Various miscellaneous fixes and improvements.

Tue May 19 14:00:00 2015 toddrme2178AATTgmail.com
- Update to version 1.2.7

* Updated to c-blosc v1.6.1.

Sun Apr 26 14:00:00 2015 benoit.moninAATTgmx.fr
- update to version 1.2.5:

* Updated to c-blosc v1.5.4.

* Added wrapper for the expert function ``set_blocksize``.
(#72 AATTesc)

* Fix setup.py to allow compilation on posix architectures
without SSE2. (#70 AATTandreas-schwab)

* Don\'t release the GIL on compression/decompression (#77 AATTesc)

* Various miscellaneous fixes.
- drop setup.patch: fixed upstream

Wed Aug 6 14:00:00 2014 schwabAATTsuse.de
- setup.patch: fix use of unknown compiler option

Thu Jul 17 14:00:00 2014 toddrme2178AATTgmail.com
- 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.

Thu May 8 14:00:00 2014 toddrme2178AATTgmail.com
- 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.
