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

Version numbers don't usually represent separate components. For some people/software the numbers are fairly arbitrary. For others, different parts of the version number string do represent different things. For example, some systems increase parts of the version number when a file format changes. So V 1.2.1 is file format compatible with all other V 1.2 versions (1.2.2, 1.2.3, etc.) but not with V 1.3. Ultimately it's up to you what scheme you want to use.
