Google said that the version number of Chromium 13 can be?

Some people think that foreigners are particularly superstitious and will not launch software with the number 13 as the version number, the most superstitious thing is that we always consider ourselves with our own ideas (I don't know how many floors an office building has, because 3, 4, and 13 cannot be found in the elevator ). The book is now being published, and Chromium 13 has been released. Google is engaged in scientific research. How can we be superstitious about these numbers? This is not a concern at all.
