Hi Muyi,

We have decided to discontinue the Seedlings release. The problem was that often they lead to quite a bit of confusion, and it was not uncommon for us to find people running it who should have had access to the production version. That was obviously not ideal given that it was pre-production quality!

We are working on a new approach which achieve the same goal as Seedlings (giving access to new functionality before the stable release is out), but we're not quite ready to announce that yet. We'll be releasing it a couple of months after the next major release (before the end of the year).
