The downloads graph at https://crates.io/crates/crossbeam-channel displays zero 7-day avg downloads for the latest version (0.3.8). This must be wrong since the latest version is widely used and definitely has been downloaded at least once.
I suspect something is wrong due to yanking. Version 0.3.5 was yanked and all versions newer than 0.3.5 appear to be downloaded zero times, which can't be true. Looks like a bug.
