wss.clients.length always returns undefined even if the clientTracking option is set to true

Hi, from [email protected] on, wss.clients.length always returns undefined even if the clientTracking option is set to true.

I wonder if people read the release notes. clients is no longer an array but a set. You should use Set.prototype.size.

No, not everyone tracks release notes. So this question was perfectly legit and helped me as well.
