Shopify API version policy is to support stable versions for 12 months. When Shopify API 2025.04 is released, we will no longer support POS UI Extension versions 1.0.0, 1.0.1, 1.1.2, 1.2.0, 1.3.0, 1.4.0, 1.5.1, 1.6.0, 1.7.0, and 2024-04.
Starting with POS version 9.31, POS UI Extensions built on these unsupported versions will no longer function. If your application uses any of these versions that will no longer be supported, please update to the latest POS UI Extension version to ensure continued functionality and support.
