ANN: C-Blosc 1.16.0 released

[Francesc Alted]

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

 Announcing C-Blosc 1.16.0

 A blocking, shuffling and lossless compression library for C

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

What is new?

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

This is an important release in terms of improved safety for

untrusted/possibly corrupted inputs.  The additional checks seem

to not affect performance significantly (see some benchmarks in #258),

so this is why they are the default now.

The previous functions (with less safety checks) are still available

labeled with an '_unsafe' suffix.  The complete list is:

  - blosc_decompress_unsafe()

  - blosc_decompress_ctx_unsafe()

  - blosc_getitem_unsafe()

Also, a new API function named blosc_cbuffer_validate(), for validating Blosc

compressed data, has been added.

Finally, a couple of potential thread deadlock and a data race have been fixed.

Thanks to Jeremy Maitin-Shepard and @wenjuno for these great contributions.

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.
