What’s new in h5py 3.1

Bug fixes

• Fix reading numeric data which is not in the native endianness, e.g. big-endian data on a little-endian system (GH1729).

• Fix using bytes as names for Group.create_dataset() and Group.create_virtual_dataset() (GH1732).

• Fix writing data as a list to a dataset with a sub-array data type (GH1735).

Building h5py

• Allow building against system lzf library by setting H5PY_SYSTEM_LZF=1. See Custom installation.

Development

• If pytest is missing pytest-mpi it will now fail with a clear error.

• Fix a test which was failing on big-endian systems.
