0.7 is not a stable series.
0.8.x shipped with a SOVERSION of 1 because an emergency ABI change
was made during the 0.7 series after we had made releases with the
The libtool versioning system has grown to be increasingly irrelevant
over the past decade, since it doesn't adequately address things like
parallel installability. Dealing with parallel installability leads
one to deal with decent package versioning and having stable ABI series,
at which point the only relevant feature is the libtool minor version
(i.e., specifying ABI additions). And ld.so ignores this value anyway.
