Happy to sponsor such an excellent work!

📢 We are happy to announce the release of Python-Blosc2 3.2.0! This release introduces the new blosc2.matmul() function. We have written a nice blog: www.blosc.org/posts/optimi... Lastly, we are excited to introduce WASM32 wheels for the first time. More info at: github.com/Blosc/python... Enjoy!

Happy to be sponsoring such an extremely useful project! Cheers! 🥂

Happy to sponsor this fine work.

@Blosc2 makes compression even better for tomography in synchrotron facilities in Europe by allowing up to 2x better compression ratio, helping already good codecs to shine even more, without almost no loose in perceived quality. Read our paper on how we achieved this: blosc.org/docs/LEAPS-I...

Happy to see this multi-year effort out of its cage! Best of luck!
