What’s new in h5py 2.6¶
Support for HDF5 Virtual Dataset API¶
Initial support for the HDF5 Virtual Dataset API, which was introduced in HDF5 1.10, was added to the low-level API. Ideas and input for how this should work as part of the high-level interface are welcome.
This work was added in PR 663 by Aleksandar Jelenak.
Add MPI Collective I/O Support¶
Support for using MPI Collective I/O in both low-level and high-level code has been added. See the collective_io.py example for a simple demonstration of how to use MPI Collective I/O with the high level API.
This work was added in PR 648 by Jialin Liu.
Numerous build/testing/CI improvements¶
There were a number of improvements to the setup.py file, which should mean that pip install h5py should work in most places. Work was also done to clean up the current testing system, using tox is the recommended way of testing h5py across different Python versions. See PR 576 by Jakob Lombacher, PR 640 by Lawrence Mitchell, and PR 650, PR 651 and PR 658 by James Tocknell.
