I'm going under the assumption that if one is a maintainer, then s/he will be reading this list. I'm also going on the assumption that users of the hdf5 port cannot magically read the maintainer's email. You can take my original post as public service for the users of hdf5. I'll note that there are 2 bug reports about the breakage: [Bug 209242] math/matio broken by science/hd5 upgrade to 1.10 [Bug 209244] math/scilab broken by science/hd5 upgrade to 1.10 I doubt that the patches proposed in these PR apply to any Fortran codes, but I'm too disinterested to investigate further. I suspect that the breakage is going to affect more ports, and for the users of these port they may not even be aware of problem (i.e., they may produce corrupt data with no obvious warning or error). The very first entry under "New Features" in the Release Notes for HDF5 1.10.0 is - API Compatibility with HDF5 1.8 Flag Was Added The 1.10 version of the HDF5 Library can be configured to operate identically to the 1.8 library with the --with-default-api-version=v18 configure flag. This allows existing code to be compiled with the 1.10 library without requiring immediate changes to the application source code. For addtional configuration options and other details, see "API Compatibility Macros in HDF5" at https://www.hdfgroup.org/HDF5/doc/RM/APICompatMacros.html. This doesn't give one too much confidence that the maintainer actually looked at the documentation. S/he simply assumed that a point release update from 1.8.16 to 1.10.0 did not change the ABI/API. -- Steve
