We are looking to release version 7.0.0 very soon. It will include new tutorial content, smarter builds and better workflows.
Version 5.0.0 will be deprecated shortly after; any projects being deployed will start to fail and will need upgrading to version 6.0.0.
Please get in contact with support if you are worried about the upgrade form 5.0.0 to 6.0.0.
Our estimation is that a small to medium size project will take less than an hour to upgrade (guide found here: https://spatial.improbable.io/docs/6.0.1/releases/release-notes/release-notes-6)
