5.6.0 2026-06-08

New

• Added SCPCardPresentDetails.overcaptureStatus to indicate whether overcapture is supported for a card present transaction. Fixes #386.
  • Note for internet reader integrations, this feature requires reader software version 2.43 or later to be installed on your internet reader.
• Added SCPLocaleConfig parameter to Terminal.initWithTokenProvider to configure localization of API error messages. Pass LocaleConfig.cardLanguagePreferenceIfAvailable to localize messages to the cardholder's preferred language when available (falling back to the device locale), or HardcodedLocaleConfig for a fixed locale.

Fixes

• Fixes #378: Fixed a crash caused by a race condition during internal logging operations.
• Preview: Surcharging - Fixed an issue where SCPSurchargeDetails.amount was not included in the amount charged, also causing an incorrect maximumAmount calculation.
• Fixes a race condition in where the reader state could be mutated after a disconnect, leaving the SDK permanently stuck in the Connected state.
