+<!-- Redirect plugin currently does not allow the final segment of a url (e.g. /v2.7/faq is valid, but /v2.7 is not)
+     to contain a period so this method is used to to allow users to access baseurl/v2.7 and be redirected to baseurl
+
+     releaseTask: when a new minor version is released, the name of this file and the title need to be updated.
