Release Naming Convention

Begining with the release of VIC 4.2, a release naming convention of VIC.MAJOR.MINOR.PATCH has been formally adopted. This naming syste was introduced by Semantic Versioning and defined as:

  1. MAJOR version: when changes are included that are not backward compatable,
  2. MINOR version: when features and new functionality are added in a backwards-compatible manner, and
  3. PATCH version: when backwards-compatible bug fixes are made.
