That's how software releases work... The devs have to create test, alpha and beta versions and people use them at various stages of development to find and fix bugs and improve the software.
If you want to try out the latest fixes or features then use the beta versions... If you're performing and stability is a must then you should absolutely only use the stable versions. If I was playing live in a club, I'd even wait a while after the most recent stable release and fully test to ensure it hasn't introduced any new issues.
