[Marta Iborra]

# Announcing C-Blosc2 2.15.0
A fast, compressed and persistent binary data store library for C.

## What is new?

This is a minor release in which a new io mode
was added to memory-map files. Furthermore, the `io_cb` read API was changed, so the
`SOVERSION` was bumped. In addition, the internal zstd sources were updated to 1.5.6 and some
other improvements were made.

## 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.
