It looks like we need this for bug #529494 (sorry). The last change to the ebuild was a while ago: 31 Mar 2014; Michał Górny <mgorny@gentoo.org> pydns-2.3.6-r1.ebuild: Add support for the new PyPy slotting. and I don't see any open bugs.
Please proceed
I see no reason why not to add the most recent release here. It has been in 6 months. 2 birds with the one stone.
HPPA, IA64, PPC and SPARC have no stable keywords to propagate.
x86 stable
amd64 stable. Closing.
