There is a upcoming new block ([round v] of ()) that is already inside the project, but it still reports always 0 as it must work like an old (round ()) block. Is it released yet? If so, when ([round v] of (1)) must be greater than 0 (or eventually must equal 1), then it should be released already, otherwise, if the block is round of 1 but still reports 0, then it is still not available yet :(
A detector for the ([round v] of ()) being released later or not, for everyone to look around. See http://scratch.mit.edu/discuss/topic/46994 to learn more.
