• API checker: Upstream-Tracker.org checks ABI/API changes for some libraries like gpgme, libgpg-error, libgcrypt.

Note that the tools can't necessary decide whether something is an ABI or API change. The output should be used as a hint to look for whether there might be a problem. We are not aware of any broken API or ABI contracts for the listed libraries.
