EAPI-3 was approved by the council during their last meeting (2010-01-18).
Which portage versions do support it?
(I wasn't able to find it in the docs.)
When can we stabilize EAPI-3 ebuilds?
(I guess this is again a council decision?)
How long do we have to provide ebuilds for older EAPIs?
(We can drop them as long as users are able to upgrade to an EAPI-3
capable package-manager for at least one year from now/after
Is this worth to be documented if it isn't?
