I'm pleased to say that h5py 3.0 is now available on PyPI. This release brings a lot of improvements, which you can read about in the release notes:
This release requires Python 3.6 or above. It will be the last release to support Python 3.6 - the next version will be tested with Python 3.7 and above.
Special thanks to Thomas Vincent, who found and fixed problems with the Mac OS wheels since the release candidate.
Thanks,
Thomas
