Also a beta version of anything is usually feature complete, meaning that all intended features have been included in it. New features can be added between the first beta and the final release though. There is also alphas which serve the same purpose as betas but are early releases that are far from feature complete. Finally there is release candidates, which are intended to become the final version unless bugs are found during the testing stage. The order in which they come is: alpha, beta, release candidate.
