Then, I expect things to settle down quickly. To answer your question, Lensfun does not have a policy for this (yet). So far, versioning has been without clear rules. But there is a proposal in the inbox of its maintainer to declare "z" as a clear patch release, so no ABI or DB changes. In contrast, a change in "y" may change both. > [...] > > Another solution could be double versioning the data, by library > SONAME and database version, > e.g. /usr/share/lensfun_$ABI/version_$DB/, which could allow to > have liblensfunN and liblensfunN-data, parallel-installable aside > each other SOVERSION. This would mean quite a bit of new developing and testing. If possible, I'd like to avoid it. Besides, there is a conceptual ugliness that the DB files do not depend on the ABI version; one would end up with duplicates. > (Btw, are you an upstream developer?

Yes, I am a developer, and everyone may contact me directly for Lensfun issues, or use the bug tracker, for that matter.
