Comment (by Roland Haas):

Interesting. Ok. The Silo one is an actual bug in HDF5 since it’s symbols are not internally consistent. This one here may be different though even so the newsletter “[…]that includes deprecated symbols (the default)[…]” to me would read as if the default settings should be a backwards compatible API (which of course Arch Linux may change if they want to be on the bleading edge).

I will give this a try on my workstation with a self-compiled HDF5 1.12.

Semantic versioning by HDF5 would be great so that API change → major version change. But then, with the Linux kernel now also updating major version numbers when the devs run out of fingers and toes to count, this is probably a futile hope…
