There are two sets of version information for libtiff. The public release numbers (like 3.7.1) and the internal libtool/so release numbers derived by a different mechanism which now appears to be set at 10.7.1.

I didn't think this separation had been made yet. I thought this was being saved for 4.x. When I build a vanilla 3.7.1 on my system, I get libtiff.so.3 -> libtiff.so.3.7.1. Because of the accidental ABI change of libtiff that happened somewhere between 3.5.7 and 3.6.1, some distributions are packaging the current libtiff as something other than libtiff.so.3. Debian uses libtiff.so.4 for 3.6.1 through 3.7.1. I believe FreeBSD and Cygwin also are using version 4.

In other words, I don't think the appearance of 10.7.1 here is happening because of a purposeful separation between the software version and the library version. Even if it were, it wouldn't seem right for libtiff.so.3 to be a link to libtiff.so.10.7.1.

Maybe there's some other explanation?
