So, I mean versions that are not quite finished and that still contain a lot of bugs and glitches. In Minecraft these versions are called "snapshots" or something. But is that an official term for it, or did Mojang just make up that meaning?

Snapshot, pre-release, nightly built, alpha, beta… Everything can apply depending on the program status.
