Apple also released a new version of iOS today, so don’t make assumptions that anything they do per Yosemite has anything to do with FCP X.
And, whatever you do, don’t even think about upgrading or updating your IS without first cloning your working hard drive – many here have been hosed by Yosemite and/or bad drivers because they rushed to push the “all too easy to push button” that Apple sends to their desktop, before testing with Pro Apps.
