Zenon,

Sadly, but no. This change has not been implemented, yet. We plan to
finally announce this change not later than the end of this month.

It appears there are some non-trivial challenges with SSP (may be you've
seen discussions on refeds and ssp list) so we are double checking our
set-up in order to avoid problems in transition.

Miro

p.s. Having in mind that we run a production service we do our best to
announce all the changes to the public lists (before and after the action)
