Changes to TUFLOW FV Version Numbering

As of the current release, the TUFLOW suite of products (which includes TUFLOW FV) has moved to a uniform versioning system. This system uses the year.minor.patch convention that reflects that already adopted by TUFLOW FV. In the new system:

  • The year corresponds to the major version number e.g. 2025.0.0. Major releases are the only releases that will admit the possibility of breaking changes. There will be one major release per year
  • Minor releases contain new features and bug fixes, but no breaking changes and increment the minor version number, e.g. 2025.1.0
  • Patch releases are bug fixes only and increment the patch version number, e.g. 2025.0.1
