Some question about .pro.shared

[Gaobo]

I have some question about .pro file.
I found Qt can create a .pro.shared file to shared my project setting, and what it need to be attention?
In Sharing Project Settings， it say:

You must always specify the ProjectExplorer.Project.Updater.FileVersion variable and use the same value for it as in the .user file.

Is that mean, i need make the .shared's FileVerson and .user's FileVerson equal ? but my co-worker's FileVerson of the .user file may not be same as me. In this case, i push the .shared file to svn, and my co-worker can use it directly ?

Anthor question is :
If i change some setting about the project, i need to change the .shared file manually?
