Woah! Did not expect that. I seriously wonder why, the update could not be more simple, and is exactly like the content browser one, in fact. Will look into it, but until then, hold of the downloads.
@allovertheglobe: You may want to reflash to the original 1.5 just in case. Sorry about the scare
Glad to know it works though, will fix. Is this what you had in mind (apart from the heart-in-mouth moment)?
