According to Debian mailinglists, the ABI/soname will change. All
symbols will be versioned, where the previous ones were not. The
upstream maintainers have decided to not include symbol aliases to the
old functions, so the new library will be binary incompatible to the old
It's too bad they break ABI with a library that has been around for
years now. Open source software can be recompiled against this, but
closed software will not stand a chance with this change.
