I don't think so. Motorola had posted a list of fixes and enhancements on their site the other day, then pulled it a short time later. Phandroid has a screen shot: Motorola’s Droid 2.1 Info Page Removed – Screenshots Inside 

I'm guessing an issue was found late in the Q/A process that Motorola decided to fix. Or you could go with one of the many conspiracy theories floating around that Motorola is evil, mean, uncaring, etc., etc. etc.
