===============================================================
Announcing c-blosc 1.7.0
A blocking, shuffling and lossless compression library for C
===============================================================
What is new?
============
This is a quite big release introducing some exciting new features:
* A new 'bitshuffle' filter is here. This is similar that the
existing 'shuffle' filter, but the shuffle takes place at bit level,
and not at byte level. With it you can expect higher compression
ratios but still having pretty good speed. For more info, see:
http://blosc.org/blog/new-bitshuffle-filter.html
* Implemented a new acceleration mode for LZ4 (updated to 1.7.0) and
BloscLZ codecs that enters in operation with all compression levels
except for the highest (9). This allows for an important boost in
speed with minimal compression ratio loss.
* Jack Pappas made great contributions allowing SSE2 operation in more
scenarios (like types larger than 16 bytes or buffers not being a
multiple of typesize * vectorsize). Another contribution is a much
more comprehensive test suite for SSE2 and AVX2 operation.
* Zbyszek Szmek fixed compilation on non-Intel archs (tested on ARM).

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 and Zlib. This way these can
automatically leverage the multithreading and pre-filtering
(shuffling) capabilities that comes with Blosc.
