That is our standard recommendation, yes. Unless you have a very specific reason to move to stable (feel free to share your reasoning here) you should stick with tests-passed, the default. Note that you’re not technically on beta, but tests-passed. However, you get notified of new betas, and likely only update when that happens, which is why it may seem like you’re on the beta branch.
Look for the line that looks like this:
version: tests-passed
To switch to stable change that to:
version: stable
(be careful not to modify indentation).
