I'm not convinced that "synfigstudio" needs vesrsioned dependency on
exact version of "libsynfig0".

Perhaps the real problem is how library mini-transition was
handled. Upstream broke it and I uploaded "synfig" (library) and
"synfigstudio" (GUI) in a way that "synfig" propagated to testing a
bit earlier than "synfigstudio". The older version of "synfigstudio"
in testing was effectively broken for few days until newer
"synfigstudio" migrated.

I agree that perhaps packages could benefit from tighter dependency.

I committed .symbols file and "dh_makeshlibs -V" override [1] so when
both packages will be rebuilt new dependency (calculated by
`dh_shlibdeps`) will look like this: "libsynfig0 (>= 0.64.0)".

However it won't save from potential breakage if future "libsynfig0"
versions will be backwards incompatible with "synfigstudio".

I think hard-coded dependency on exact version of "libsynfig0" is a
bad idea.

I'm not sure how to handle this bug. Perhaps I need advise on how to
upload future updates to "synfig" package without breaking
"synfigstudio"...  Would it be a good idea to follow the usual
transition procedure when the only one dependency package is involved
to library update?
