One of the many wonderful things about the beta is that Pro and Server feature sets are unlocked for all users. If you’re on Standard, now is the time to archive those e-mails and OCR those PDFs; if you’re on Standard or Pro, you have to try the new enhanced Server, not least because you’ll probably never get another chance without paying the steep differential (which is absolutely worth it if you have a use for it, but normally the only opportunity to try it out first is during the original trial period before you license up, and most people don’t get that far). So far the improvements to Server are my favourite thing in v4 and worth the upgrade just in themselves.
