Comment (by Roland Haas):

Interesting. Wonder what changed. I know that 1.10 is the version that goes from hid_t being int to int64. There’s also a version that implements file locking and prevents more than one process (on the same node usually) from opening the same HDF5 for writing.

The updated tarball will only go into master so can easily be reverted if it causes problems.
