CatLight 2.17 will automatically discover new builds, releases and work item queries. When you monitor the whole project, and new item is added to it, CatLight will start monitoring it automatically.
By default, discovery happens every 30 minutes, but you can trigger it at any time by pressing refresh button on the dashboard. Discovery period is configurable in application settings. Keep in mind that this process can create a significant load on your server, so we advise to do it infrequently.
