Please upload into PPA, upload rdepends and wait for them to rebuild.
Find problems together with other interested people.
Please patches or even upload patches into the archive, only then
upload new library into the archive for a quick and smooth transition.

It requires both and across all architectures (i386, amd64, armel,
armhf and powerpc).
