Announcing C-Blosc2 2.17.0

A fast, compressed and persistent binary data store library for C.

What is new?

This introduces some new features and improvements:

  • New b2nd_copy_buffer2() function for copying buffers with typesizes larger than 255. The previous b2nd_copy_buffer() function is now deprecated and will be removed in a future release.

  • Support repeated values larger than 8-bit, also for n-dim arrays. This is useful for compressing arrays with large runs of repeated values, like in the case of images with large areas of the same color.

  • Fix a leak in the pthreads emulation for Windows. Fixes #647. Thanks to @jocbeh for the report and fix (#655).

  • Update zstd to 1.5.7. Thanks to Tom Birch.

For more info, please see the release notes in:

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 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.
