The release +team will propose tagging the Kolla deliverables as EM, but this should only be +done once all other dependent projects have made their final release, and final +Kolla releases have been made including those dependencies. + +After a branch enters EM, we typically do the following: + +* stop backporting fixes to the branch by default. Important fixes or those + requested by community members may be merged if deemed appropriate +* stop publishing images to Dockerhub +* stop actively maintaining CI + +End of Life (EOL) +----------------- + +Once a branch has been unmaintained (failing CI, no patches merged) for 6 +months, it may be moved to EOL. Since this is done at different times for +different projects, send an email to openstack-discuss to keep the community +informed. |
