What do the numbers in a version typically represent (i.e. v1.9.0.1)?

Question

Maybe this is a silly question, but I\'ve always assumed each number delineated by a period represented a single component of the software. If that\'s true, do they ever rep

Answer 1

A combination of major, minor, patch, build, security patch, etc.

The first two are major & minor-- the rest will depend on the project, company and sometimes community. In OS's like FreeBSD, you will have 1.9.0.1_number to represent a security patch.
