Versioning scheme

The versioning scheme used by Planfocus follows a standard semantic versioning (semver) convention, which is widely used in software development. 

In semver, version numbers are represented in a three-number format: major.minor.patch.

Major 

Indicates significant changes to the product that are not backward-compatible. This number is incremented when there are major changes to the software, such as significant feature enhancements or a complete redesign of the user interface.

Minor

Indicates smaller changes or new features that are backward-compatible. This number is incremented when new features are added to the product or existing features are significantly improved.

Patch

Indicates bug fixes or small improvements that are backward-compatible. This number is incremented when bugs are fixed or minor improvements are made to existing features.

In some cases, version number can include the suffix "-alpha" or "-beta" which indicates that the product is still in the alpha stage and is part of a pilot program. This is used to differentiate it from a stable release.
