# Announcing C-Blosc2 2.1.1
A fast, compressed and persistent binary data store library for C.
## What is new?
The Blosc development team is happy to announce a new release of C-Blosc2.
This is a maintenance release for fixing a bug affecting [ARM platforms](https://github.com/Blosc/c-blosc2/issues/392)
). Also more warnings and fuzzer issues has been fixed.
C-Blosc2 should be backward compatible with C-Blosc, so you can start using
it right away and increasingly start to use its new functionality, like the
new filters, prefilters, super-chunks and frames.
See docs in: https://blosc2.readthedocs.io
For more info, please see the release notes in:https://github.com/Blosc/c-blosc2/blob/main/RELEASE_NOTES.md
Also, there is blog post introducing the most relevant changes in Blosc2:https://www.blosc.org/posts/blosc2-ready-general-review/
## 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
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.
