> Do we have freeze exception process in terms of stable branches

We don't, the whole freeze and exception process existed only as a
lore on the mailing list, I guess it's time to codify it.

Here's proposal to put under
https://wiki.openstack.org/wiki/StableBranch#Releases

 The stable-maint and release teams work together to publish point
releases from the stable branch.  SeeStableBranchRelease for details
about how these releases are prepared.
+
+One week before the planned point release, stable release manager
will announce that stable branch is frozen
+to allow testing before the release. Freeze exceptions can be
proposed on openstack-stable-maint list where
+stable-maint team will try to reach consensus.
+

Also not codified is the exception process for rule-breaking changes,
what about this at the end of
https://wiki.openstack.org/wiki/StableBranch#Appropriate_Fixes

 * Incompatible config file changes
+
+Proposed backports breaking any of above guidelines can be discussed
as an exception requests on
+openstack-stable-maint list where stable-maint team will try to reach
consensus.
