Well I just wanted to clear up what the various release levels mean, or rather, what they mean for my software. So here's a bit of a guide:

Pre-Alpha: highly unstable and not finished, but has been used at least twice without segfaulting, crashing, crashing something else, freezing X, freezing the whole system, someone dieing, or an unexpected black hole forming.

Alpha: unstable and not finished, but can at least be used most of the time.

Beta: Mostly finished, but still a few bugs floating about.

RC (Release Candidate): still Beta, but it's been there so long I wanna make it look like I'm progressing.

Final: not usually marked as final, but it won't be marked as one of the above. This release level is usually when I've finished something and ironed out all the bugs, or have just reached the point of "sod it, that'll do."
