+- Since OPNFV is using several upstream projects, typically fixes in the upstream projects will apply as fixes for OPNFV. Therefore complete **maintenance revisions of the upstream projects** (i.e. minor versions) can be used as suitable backports for OPNFV  maintenance releases.
 - Since OPNFV is a midstream integration effort, also test cases might be suitable backports
   in case they are related to critical bugs found in stable.

 If the patch you're proposing will not cherry-pick cleanly, you can help by resolving the conflicts yourself and proposing the resulting patch. Please keep Conflicts lines in the commit message to help reviewers! You can use git-review to propose a change to the stable branch with::
