No, don't get exited, I couldn't find it. I just was looking to the Updates page HTML code (even i don't know HTML), when I found this in somewhere:
5.00.2314.1000
What is it? It looks like a 'site number', messed up. It has one more digit than real site numbers.
Example of a 'real' site number:
207.199.1.106
See what I mean?
Can you guys help me, please?
