-Stable Support Policy
----------------------
-
-Since the `Extended Maintenance policy`_ for stable branches was adopted
-OpenStack projects will keep stable branches around after a "stable" or
-"maintained" period for a phase of indeterminate length called "Extended
-Maintenance". Prior to this resolution Tempest supported all stable branches
-which were supported upstream. This policy does not scale under the new model
-as Tempest would be responsible for gating proposed changes against an ever
-increasing number of branches. Therefore due to resource constraints, Tempest
-will only provide support for branches in the "Maintained" phase from the
-documented `Support Phases`_. When a branch moves from the *Maintained* to the
-*Extended Maintenance* phase, Tempest will tag the removal of support for that
-branch as it has in the past when a branch goes end of life.
-
-The expectation for *Extended Maintenance* phase branches is that they will continue
-running Tempest during that phase of support. Since the REST APIs are stable
-interfaces across release boundaries, branches in these phases should run
-Tempest from master as long as possible. But, because we won't be actively
-testing branches in these phases, it's possible that we'll introduce changes to
-Tempest on master which will break support on *Extended Maintenance* phase
-branches. When this happens the expectation for those branches is to either
-switch to running Tempest from a tag with support for the branch, or blacklist
-a newly introduced test (if that is the cause of the issue). Tempest will not
-be creating stable branches to support *Extended Maintenance* phase branches, as
-the burden is on the *Extended Maintenance* phase branche maintainers, not the Tempest
-project, to support that branch.
