# Checkout UI extensions - Extensions in the reductions render before/after targets will now render in the header order summary on 1 page mobile checkouts

As of October 11, 2024, checkout UI extensions targeting the `purchase.checkout.reductions.render-before` and `purchase.checkout.reductions.render-after` extension targets will now render in the order summary at the top of the page for one page mobile checkouts. Previously, extensions in these targets would only appear in the order summary at the bottom of the page. This will apply to checkout UI extensions on all API versions.
