Introduction to Versioning
Mobile application versioning is critically important for tracking changes, managing updates, ensuring compatibility, and communicating changes to users. Proper versioning strategy provides clear version identification, supports backward compatibility, and enables effective update management.
Mobile applications utilize multiple version numbers: user-facing version (semantic versioning), build numbers, version codes for stores, and internal versioning. Understanding different versioning schemes and when to use them is critically important.
Versioning Schemes
Semantic Versioning
MAJOR.MINOR.PATCH (for example, 2.3.1)
Components:
MAJOR: Breaking changes
MINOR: New features, backward compatible
PATCH: Bug fixes, backward compatible
Benefits:
Clear change indication
Standard format
Compatibility signaling
Version Code (Android)
Incrementing integer for store.
Requirements:
Always increasing
Used by Play Store
Not visible to users
Unique per release
Build Number (iOS)
Incrementing build identifier.
Requirements:
Increments with each build
Can be the same as version code
Used for tracking
