=========================================================
Announcing Blosc 1.2.2
A blocking, shuffling and lossless compression library
=========================================================

What is it?
===========

Blosc (http://www.blosc.org) is a high performance 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 is the first compressor (that I'm aware of) that is meant not
only to reduce the size of large datasets on-disk or in-memory, but
also to accelerate object manipulations that are memory-bound.

There is also a handy command line for Blosc called Bloscpack
(https://github.com/esc/bloscpack) that allows you to compress large
binary datafiles on-disk. Although the format for Bloscpack has not
stabilized yet, it allows you to effectively use Blosc from you
favorite shell.

What is new in 1.2 series?
================

- Now it is possible to call Blosc simultaneously from a parent
threaded application without problems. This has been solved by
setting a global lock so that the different calling threads do not
execute Blosc routines at the same time. Of course, real threading
work is still available inside Blosc itself. Thanks to Thibault
North.

- Support for cmake is now included. Linux, Mac OSX and Windows
platforms are supported. Thanks to Thibault North, Antonio Valentino
and Mark Wiebe.

- All important warnings removed for all tested platforms.
