Whoah, 1.2 is super old. In my opinion, one of the hallmarks of static analysis tools (and libabigail is just a static analysis framework) is to be able to recognize patterns used by developers, as much as we can. Because we can't really do that at once, we try to add recognition of new patterns (of ABI changes) at every single release. Furthermore, there are some change patterns that ought to be recognized and categorized as harmless, whereas some others out to be categorized as harmful. That categorization is also the result of input coming from users as you, fine fellows. All this to say that with every new version, the number of new supported features and bug fixes is potentially big. To alleviate that, some distributors update libabigail even in their old stable distros, because the value of having an up to date version there outweighs the potential drawbacks. > Given we still support v19.11 on Ubuntu 18.04.2. So maybe that's a discussion worth having with the maintainer of the Ubuntu package of Libabigail? > I think it's worthwhile keeping the suppression until v20.11? [...] David Marchand writes: > In Travis, we currently use libabigail 1.6 (mainly because I did not > update to 1.7 when it was released). Right, that's probably another way to stay up to date independently from the underlying distribution. I hope this helps, Cheers, --=20 =09=09Dodji
