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

Major.Minor.Bugs

(Or some variation on that)

Bugs is usually bug fixes with no new functionality.

Minor is some change that adds new functionality but doesn't change the program in any major way.

Major is a change in the program that either breaks old functionality or is so big that it somehow changes how users should use the program.
