Aurora will never be "stable" - it is an actively developed game that will continue to have new features and save-breaking updates as long as Steve has new ideas he wants to implement. The pace of updates will probably slow down soon (and already has slowed down from the update-per-day that we had on release) as most of the bugs get fixed. For reference, there was about a week between v1.8 and v1.9, so we can probably expect something similar or slightly longer for v1.10. If you want to make a tutorial, that is probably fine right now, since almost all of the current patches have to do with bug fixing rather than new features.
