Hi, A new API for Vitrage template add and template delete was added this week. As part of this change, Vitrage templates are now stored in a database and are no longer read from the file system. In case you are using templates, make sure to call the new API and add them to Vitrage once you get the latest version. More details can be found on the spec [1] and on Vitrage API [2] and CLI [3] documentation. Thanks, Ifat.
