We try to update at least once a month, but sometimes goes a little longer. We don't have a strict schedule release.
I'd suggest if a UA returns unidentified, keep it until the next update, which you can check by pinging the version/date URLs listed on browscap.org.
Thanks

Awesome, thanks for the reply.
Follow-up question; is there a sure-fire way to tell that BC wasn't able to find a match?
Yup, the "fallback" is when the browser identified is "Default Browser"
:)
