Version Numbering Rules

TodoTxtMac uses the following semantic versioning number system.

Version number components

Version X.Y.Z

• X: Major version
• Y: Minor version
• Z: Point version

Version number increments

Major version number is incremented when:

• major UI enhancements are made (e.g., adding a sidebar)
• major refactor that changes how everything works (e.g., switching from a cell-based table view to a view-based table view)
• major changes to the model (e.g., entire model swapped for a new one, or a change that makes the new model incompatible with the old one)
• programming language changes (e.g., port from Objective C to Swift)
• application name changes

Minor version number is incremented when:

• minor UI enhancements are made (e.g., status bar, menu items, placement of controls)
• minor changes are made to the model (e.g., addition or refactoring of a small number of methods or properties)
• changes are made that could break compatibility with existing user preferences (e.g., changing filter and sort preferences)
• compatibility with older Mac OS X version(s) is dropped
• application icon changes

Point version number is incremented when:

• minor bug fixes or enhancements are made that require no changes to the model or major frameworks
• code is refactored without changing the model or frameworks
