Percona packages for Debian Stretch

Good morning,

Debian Stretch has been released but there are not Debian package available yet.
Is there any due date?
Some of our customers are waiting them for upgrading there production servers.

Thank you.

I’ve run successfully on old packages from Jessie (only for PXC) for over two months without any issue. But packages have been released since then:
