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

There is the Semantic Versioning specification

This is the summary of version 2.0.0:

Given a version number MAJOR.MINOR.PATCH, increment the:

1. MAJOR version when you make incompatible API changes,
2. MINOR version when you add functionality in a backwards-compatible manner, and
3. PATCH version when you make backwards-compatible bug fixes.

Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
