Jan 1, 2025January 2025 monthly summary for activemerchant/active_merchant focused on stabilizing Nuvei 3DS transactions and improving test reliability. The primary work addressed Nuvei 3DS transaction robustness when three_ds_2 data can be null and reduced flakiness introduced by Nuvei API changes by introducing a round_down method to stabilize remote tests. These changes improve transaction success in edge cases and bolster confidence in deployment through a more stable test suite.
