Nothing happens to the old package. When a new shared library comes out that is incompatible with an old shared library, both libraries should be installed, this is why the soname is in the package name. It allows simultaneous installation of libgpgme0 and libgpgme1. By having both packages, third party programs compiled and linked angainst either version will run fine. Eric
