Has MainStage been abandoned?

Is MainStage still supported? It's been over a year since the last update (3.6.6). Since then, a lot of tools have been added to Logic, and MainStage has always had the same plugins and content. We haven't had that for a long time, and it makes me wonder if there will be another update, or if it's time to look for an alternative? Does anyone have any information? Regards.
