I did last night. Worked just fine on my old 5.0.1 install. Took quite awhile since basically *everything* got an update. It’s probably faster to download a full installer, just because it’s more efficient to download one big file than lots of smaller ones.
If you’re a bit concerned about it, I’d recommend just downlaoding our “All-in-one” installer to plop a full 5.1.0GA stack down in another location. Then you can try out the new release without updating your current release if you want.
