Comment 4 for bug 1884326

Hey Olivier! I looked at the librsvg upload in the queue just now. I'm a bit worried about the symbols removal in librsvg2-2. Looking at the diff:

Doesn't his break the current ABI? Those seem to be public symbols that are being removed. Doesn't this warrant a librsvg soname bump, to something like librsvg2-3 or something? I'm worried about this breaking existing applications.

Was this investigated? Am I just being overly paranoid?
