# Announcing C-Blosc2 2.21.1
A fast, compressed and persistent binary data store library for C.
## What is new?
Fixed a regression in 2.21.0 causing incompatibility
at least with Fedora and Gentoo. Thanks to Michał Górny (@mgorny) for
reporting and Teodor Tsirpanis (@teo-tsirpanis) for the actual fix.
For more info, see the release notes in:
https://github.com/Blosc/c-blosc2/blob/main/RELEASE_NOTES.md## What is it?
Blosc2 is a high-performance data container optimized for binary data.
Blosc2 is the next generation of Blosc, an [award-winning]
(
https://www.blosc.org/posts/prize-push-Blosc2)` library that has been
around for more than a decade.
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.
