In this article, we will explain our policy for assigning product versions.

Unified Version

NovoNotes adopts a unified versioning system where multiple products share the same version number. For example, if Duo and SideRack are released simultaneously, they will be assigned the same version number. When using multiple products together, we recommend using products with similar version numbers as much as possible to avoid compatibility issues. If you encounter compatibility problems, first ensure that the major version is the same or the latest.

Version Format

Additionally, at NovoNotes, we represent versions in the format of Major.Minor.Patch. For example, in the case of v2.1.3, it means Major version 2, Minor version 1, and Patch version 3.

Meaning of Each Element

Major Version: Incremented when there are incompatible, breaking changes. Updates may sometimes require a paid upgrade.
Minor Version: Incremented when new features are added while maintaining backward compatibility.
Patch Version: Incremented for bug fixes that maintain backward compatibility.

Changes Included in Updates

Updates may include the following types of changes:

	Project File Compatibility	Compatibility Between Products	Output Sound	User Interface
Major Version	Project files created with older versions may not open, but a project file conversion feature will be provided as a countermeasure.	May include breaking changes that are not compatible with other products. We recommend checking if the other products you plan to use in combination are compatible with the new version and updating them simultaneously.	May include changes that are noticeable to the ear.	Major changes or removals may be made to the existing UI.
Minor Version	Project files created with older versions can be opened as is.	Does not include changes that break compatibility with other products.	While the output may not be exactly the same, the changes will sound the same to the ear.	May include new features.
Patch Version	Project files created with older versions can be opened as is.	Does not include changes that break compatibility with other products.	No changes	May include fixes that do not affect usability.

Project File Compatibility
