Versioning and Update Policy

The Netcetera iOS 3DS SDK follows the software versioning convention. The releases have semantic versioning scheme, meaning the version name will be composed of PROTOCOL.MAJOR.MINOR.PATCH.

  • PROTOCOL - major protocol version, i.e. 2
  • MAJOR - new features
  • MINOR - improvements
  • PATCH - bug or security fix

Because of limitations by Apple, the minor and patch numbers are concatenated together. When ThreeDS2ServiceSDK.getSDKVersion() is called, the concatenated version will be retuned, i.e. for version, the returned string would be 2.2.10.

It is recommended that the 3DS Requestor App always use the latest available version of the SDK.
