ANN: C-Blosc 1.13.0 relased!

[Francesc Alted]

===============================================================

 Announcing C-Blosc 1.13.0

 A blocking, shuffling and lossless compression library for C

===============================================================

What is new?

============

A serious optimization of memory copy functions (see `blosc/fastcopy.c`) .

This benefits the speed of all the codecs, but specially the BloscLZ one.

As a result of the above, the BloscLZ codec received a new adjustment of

knobs so that you should expect better compression ratios with BloscLZ too.

Also, the LZ4 codec internal sources have been updated to 1.8.0. And internal

Zstd sources have been updated to 1.3.3 too.

For more info, please see the release notes in:

https://github.com/Blosc/c-blosc/blob/master/RELEASE_NOTES.rst

What is it?

===========

Blosc (http://www.blosc.org) is a high performance meta-compressor

optimized for binary data.  It has been designed to transmit data to

the processor cache faster than the traditional, non-compressed,

direct memory fetch approach via a memcpy() OS call.

Blosc has internal support for different compressors like its internal

BloscLZ, but also LZ4, LZ4HC, Snappy, Zlib and Zstd.  This way these can

automatically leverage the multithreading and pre-filtering

(shuffling) capabilities that comes with Blosc.

Ooops.  While testing C-Blosc 1.13.0 against python-blosc I discovered a small glitch, so I am quickly releasing 1.13.1 fixing this:

===============================================================

What is new?

============

Fixed a bug uncovered by the python-blosc test suite: when a buffer is

to be copied, then we should reserve space for the header, not block

pointers.
