@magjac, in light of the next release involving a major version bump, do we need to bump the
GVPLUGIN_VERSION? I wasn’t thinking about this when I reviewed the related MRs, but it occurred to me when re-reading GRAPHVIZ_PLUGIN_VERSION arithmetic (#1812) · Issues · graphviz / graphviz · GitLab. I think the answer is probably “no,” as the changes are backwards compatible wrt plugins. But we could equally well bump the plugin version to be conservative.
I think the plugin version is only relevant for out-of-tree plugins. Any plugins that live in the Graphviz repository could deal with a plugin version that was just the Graphviz release version and bumped with every single release. There’s no expectation that an in-tree plugin can be loaded by a different version of Graphviz.
