Today, the Gentoo Council has approved the specification for EAPI 5

a new ebuild hits the mirrors) or from the git repository. The gitweb
for the PMS can be found here:

As the text was just approved, it will take a while before package
managers release new versions that declare support for EAPI 5.
As such, the new EAPI 5 can't yet be used in the main tree. You will
be notified as soon as you can start reaping the benefits.
