# Changes to 2019-04 version timeline

With the evolving concerns around COVID-19’s impact on communities around the world, we know that partners and merchants are making adjustments to continue running their businesses smoothly. That’s why we’ve decided to postpone the April 1 version removal from **April 1, 2020** to **July 1, 2020**.

This change in the timeline means that you have until July 1 to update your apps to account for changes in both 2019-07 and 2019-10 API versions. The move from page to cursor-based pagination comes into effect for **all** endpoints on July 1. This simplifies the migration process for apps that need to update their pagination strategies.

To see the deprecated API calls your apps are making, check out the [API Health report](https://shopify.dev/concepts/about-apis/versioning/api-health) on the Partner Dashboard.
