Description:
CBA 3.10 release on Steam happened ~15 minutes before our scheduled mission start. The server is running essentially 24/7 and needs to be manually kicked into grabbing mod updates from the SWS.
After loading in, those who got their clients updated got slapped by PBO Checking for having "CBA 3.1" which was claimed to be older than CBA 3.9; I checked CfgPatches in the config viewer pretty much immediately and it was showing version = "3.10.0.190314"; for all CBA classes that had a version defined.

Steps to reproduce:

• Have CBA 3.10 loaded
• Join a server running CBA 3.9 and PBO Checking
• Observe the chat message dropping the zero in the version number and saying the newer version is older

Where did the issue occur?

• Dedicated

Additional information:

• For us, this time, it was only a display issue. But if the system ever has to compare x.1.x to x.10.x, it might end up calling them identical.
