    Versioning in PHP SDK

    Learn how versions are created for the PHP SDK.

    Overview

    The SDK versioning is based on the Semantic Versioning.

    The version number is composed as follows:

    [Major-Version].[Minor-Version].[Patch-Version]

    Major-Version

    Changes here indicate significant (breaking) changes which are not backwards compatible.

    Minor-Version

    Changes here indicate new features in the SDK.

    Patch-Version

    Changes here indicate minor small changes like improvements, refactoring, or bug fixes.
