 Every release line (Ginkgo, Hawthorn, etc) has a branch that accumulates changes destined for that release (``open-release/ginkgo.master``, ``open-release/hawthorn.master``, etc). Periodically, we tag that branch (``open-release/hawthorn.1``, ``open-release/hawthorn.2``, etc). After a few releases, we might still add important fixes to the branch, but not make a new tagged release. At that point, someone installing that line will want to install from the branch, not the tags.
 
+From Teak onwards we have changed the nomanclature from ``open-release/<named-release>.master`` to ``release/<named-release>``. Subsequently tags are changed from ``open-release/<named-release>.1`` to ``release/<named-release>.1``.
+
 If an installation of a tag fails, try the corresponding release line master branch, it may have a fix.
