The documentation about OCI and appc created uncertainty for users, as
shown by the issues #3777 and #3745.
This is an attempt to clarify that although not much development is
happening in appc, rkt will not drop the ACI support.
Once this PR is merged, I would like to delete the project
https://github.com/rkt/rkt/projects/5 as it does not contain anything
and we have https://github.com/rkt/rkt/projects/4 to track the progress
of OCI native support.
rkt's native [image format](#aci) and [runtime environment](#pods) are those defined by the [specification][appc-spec].
_Note that as of late 2016, appc is [no longer being actively developed](https://github.com/appc/spec#-disclaimer-), and future versions of rkt will instead [natively use OCI formats](https://github.com/rkt/rkt/projects/4)._
_Note that as of late 2016, appc is [no longer being actively developed, other than minor tweaks](https://github.com/appc/spec#-disclaimer-). However, appc is fully functional and stable and will continue to be supported. Future versions of rkt might gain [native support of OCI formats](https://github.com/rkt/rkt/projects/4)._
