We had some staffing shortages over the past few weeks, so we've been dragging on getting a 3.X tagged as stable, but rest assured it's a high-pri item for us and we're working to get something out as quickly as we can. 3.X brought some pretty massive changed, so we're being a bit purposefully cautious about tagging something as stable. If you've deployed any of the 3.X tags we'd love to hear how it's going for you 🙂
