[Francesc Alted]

# Announcing C-Blosc2 2.0.3
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 improving performance of the BloscLZ codec,
introducing a new `blosc2_vlmeta_delete()` function and some other small
improvements and fixes.

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:

Also, there is blog post introducing the most relevant changes in Blosc2:

## 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.
