Two pumps, revisited

Version 2.4A: a new Paradigm?

Remember this image from my March 22 post, A Tale of Two Pumps?

Take a close look at the displays.  The one on the bottom right, the “new” one (actually, a refurbished old one, hence the earlier serial number) is running on Paradigm Software Version 2.4A, while my previous one was on Version 2.3A.  This “upgraded version” didn’t come with nearly the same fanfare as, say, when my cell-phone gets hit with the next Android OS, but it makes me wonder: what’s new?

Or more importantly: what glitches existed in version 2.3A (and I assume 2.2, 2.1, and 2.0) that Medtronic had to be so sneaky about correcting?
