# Hydrogen January 2026 release

The Hydrogen January 2026 release (v2026.1.0) is out. This is a quarterly API version bump to Storefront API 2026-01 and Customer Account API 2026-01.

* Updated Storefront API and Customer Account API to 2026-01 ([#3434](https://github.com/Shopify/hydrogen/pull/3434))
* The `cartDiscountCodesUpdate` mutation now requires the `discountCodes` argument. If you have custom cart discount code logic, verify your mutations include this field before upgrading.
