When you see this sign " * " behind the version number, what does it mean?
The asterisk (*) in a common symbol usually meaning "all". In this case, it means "all sub-versions" -- for example, 3.* means all versions that start with 3 (3.0, 3.1, 3.2, 3.6.18, etc). In version numbers, it's a convenient way to specify "all versions greater than or equal to 3.0 and less than 4.0".
