[maxmsp] Re: Max 5: What It Is (and Isn't)

Wow.  This sounds great.  I'm pretty new to Max (just started earlier this year), so having not "grown up" with the program, I was always a little baffled as to why the overall interface had not been updated.  I feel the same way about Pro Tools.
Anyway, I'm a student, and my 9 month license expires in December.  I would certainly like to and can probably afford to wait until 5 is released to buy the full license.  Does anyone have any idea as to what Cycling's free upgrade window for recent buyers has been in the past?
