Dear Aaron,

the message is not necessary. I removed the message (rhdf5 2.17.6).

Dear list and Bernd,

rhdf5 v2.17.5 now prints out a message when h5createFile() gets called:

[1] "Set libver lower bound to 18"
[1] TRUE

I'm not a HDF5 expert, but is this message really necessary? It only
seems helpful if someone gets errors from trying to read a file created
in this manner with a HDF5 library version < 18. However, at that point,
they're probably not in the same R session (or, indeed, using R/BioC at
all) and will have long forgotten about this version info.

If it is required, then wouldn't message() be a more appropriate output
method? This would allow me to silence it with suppressMessages().
