New:

The SDK now supports German, Italian, Danish, Norwegian, Hungarian, Bulgarian, Slovenian, Swedish, and Chinese (Simplified). See Change the language.

Changed:

The SDK now declines store-and-forward transactions for cards with a blocked BIN (bank identification number).

Deprecated:

suppressFirmwareUpdateIndicator is deprecated. Use showCardReaderFirmwareUpdate and showDockFirmwareUpdate instead, so you can control the firmware update indicator for the card reader and the dock separately.

Fixed:

We fixed an issue where Simulator builds failed to load the bundle when the host app did not re-sign the framework.

Info:

Built with Xcode 26.3
