Not earth shattering news, and who knows if there isn’t some “extra stuff” in it for the Beta releases, but I just realized that OWB is placing more than 1GB of it’s own bits on my virtual workstation. Beta4 would not fit on one CD (800 MB).
Of course the actual release might differ, and your mileage may vary, etc. That, and who really cares about disk space these days? Disk space is cheap! 🙂
