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.
This has worked great with python3.3 transition.

Possibly setup a transition tracker on
http://people.canonical.com/~ubuntu-archive/transitions/
(there are a few examples in the branch to try out locally, see the
branch link at the botton of any tracker)

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