That is true, I did not explain clearly the status. But I suppose I
can then convince you that a LOT of API changes occured by looking at
the NEWS file: https://git.enlightenment.org/core/efl.git/plain/NEWS?id=v1.8.1

Among other things, EFL 1.8 now has a mandatory dependency on bullet
library, which makes it much less suitable on light embedded systems ;
for example, I think bullet is not part of buildroot packages yet.

Your request is justified. See above about the API compatibility.
