You never do that in this situation, since it tells setup to install libidn12 while removing libidn11, which it dutifully did. Why'd you even get the idea that you should obsolete libidn11? > Maintainers: is that something that we should not do on a package ABI > break? No, not at all. You never obsolete library packages unless they really need to be removed and replaced by something else. > How should maintainers handle such situations in cygport? Nothing to do there, move along. the older library version continues to exist and is used until all packages that depend on it have updated. > I would like to know the correct approach to take to mitigate this and > future such situations before I create a curl -2 package release. What you should check is that there is no transitive dependency to libidn11 left in the dependency chain for anything that depends on a package that uses the newer version. If that is possible you ideally need to update all involved packages together.
