# Announcing C-Blosc2 2.13.0
A fast, compressed and persistent binary data store library for C.
## What is new?
A new filter for truncating integers has been added. Furthermore, the zstd codec
has been optimized specially when using dicts. And finally, the grok library
will be initialized when loading the plugin. This evicts having to import it in
some use cases.

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.
