They are not beta, they are not test, betas of a to-be-new release are released before a version is released as fresh. And once a new version (e.g. 24.8) will be released, it will become the fresh version and the so far fresh (24.2) version will become the still version. Naming and then renaming releases in between would be even more confusing; that actually was done in the past by having Fresh and Still names but people didn’t grok the rotating scheme so now just version numbers are used.
