Normal software developing stages:
In development = If compiles is good. No guarentees to you or your machine. Neutrinos can explode and there will be monsters, using it will rise dramatically the possibilities that you will lose your job, your GF, your hair, and will be plain and absolutely NORMAL. YMMV.
Alpha Software = All features complete, but you should consider everything broken by default. Explosions can happen. ( ) Until developers open the bug tracker, assume they know about their bugs.
Beta Software = All features complete and hopefully working, consider most features broken by default, but mostly minor, if developers have open bug trackers, bug reports should go there.
Release Candidate = All features complete and working with some surprises here and there, most features working OK by default.
Final Release = All features complete and working as intended, there can be bugs, but shouldn’t be many.
Since Blender 2.8 is in alpha stage, consider everything broken by default.
