Why won't iTunes 12.0.1 update?

Question

iTunes

Updated to OS X Yosemite and hangs information that there is an update to iTunes 12.0.1. I press update, it is updated - it downloads 210+ mb and everything is ok, but the update still remains. In the information about the program in iTunes version 12.0.0.140. It looks like it should, in the style of the system.
