By the way, thanks for pointing out the ABI compliance checker, it looks like a 
tool I should be
using to evaluate changes to the libtool version info, instead of doing it 
manually, as I did for
4.2-rc1.

> > completely compatible with version 4.1.3 as shown by the attached report.
> 
> I actually changed it back to 7.1.1 earlier today in our snapshot release 
> (coincidentally
> a little before you sent your question), because we decided to disable the 
> diskless file
> implementation, which was not finished and not ready for prime time.  To 
> support
> diskless files, a new constant had been defined in netcdf.h, NC_DISKLESS, as 
> a flag to
> nc_create(), which we thought had changed the interface to that function, 
> requiring
> bumping the soname version.
> 
> I may have been misinterpreting the meaning of "interface change", but it 
> seems that
> with the 4.2-rc1 library, you could write code that wouldn't link with a 
> 4.1.3 library,
> due to the addition of the new mode flag.  In any case, you'll find that 
> constant gone
> in the current snapshot and the next release.
