Hello,
I plan to bump libtommath to 1.2.1 in Rawhide, which bumps the respective
shared library to libtommath.so.1.2.1. According to repoquery all dependencies
depend only on libtommath.1, so no rebuild should be necessary:
$ dnf repoquery --releasever rawhide --whatrequires 'libtommath.so.*'

Please correct me if I'm missing something.
Your first step should be checking for any ABI changes using abipkgdiff
and rpmsodiff. Only if there are removed symbols do you need to worry
about rebuilding consumers. However, added unversioned symbols do mean
that backwards compatibility is not preserved (i.e. an application built
against a newer version, say 1.2.1, might not work with 1.2.0 installed
if it depends on a symbol introduced in 1.2.1).
Thanks for the pointers, much appreciated!
Both abipkgdiff and rpmsodiff seem to be happy, i.e. there were no
added/changed/removed symbols between 1.2.0 and 1.2.1, so the bump
should be safe.
Cheers,
Frantisek
