[FFmpeg-user] version numbering help

[Elliott Balsley]

The general answer is:
Since there is only one development branch in the 
FFmpeg project it is very unlikely that a particular 
past commit is not in current FFmpeg.
Ok that makes sense, thank you.

This is one month older and cannot contain a later 
commit.
How do you determine that it’s one month older?
