Ah I see, the stable build hasn't updated for a long time and I was using it.
We haven't put out a release in a long time.
It pays to note that our build classifications are largely misleading. Stable, unstable, and unusable, don't necessarily imply that the builds are stable, unstable, or unusable at all.
Generally speaking, for any target that has a stable release, it should be perfectly safe to switch over to the development snapshots. In fact due to the extreme length of time since the last release, I would advise and wholeheartedly recommend doing so.
