# Announcing C-Blosc2 2.15.1
A fast, compressed and persistent binary data store library for C.
## What is new?
This is a maintenance release in which we are fixing calling instructions
more advanced than available in current CPU, causing a SIGKILL.
Furthermore, a new `b2nd_nans` function has been added. In addition,
the internal LZ4 sources were updated to 1.10.0 and some
other improvements were made.
For more info, please see the release notes in:

## What is it?
Blosc2 is a high performance data container optimized for binary data.
It builds on the shoulders of Blosc, the high performance meta-compressor
(
https://github.com/Blosc/c-blosc).
Blosc2 expands the capabilities of Blosc by providing a higher lever
container that is able to store many chunks on it (hence the super-block name).
It supports storing data on both memory and disk using the same API.
Also, it adds more compressors and filters.
