# Updates to Theme Information Access in Shopify

**Action Required:** Developers currently using the BOOMR variables for theme identification and customization should begin transitioning to `window.Shopify.theme` properties. The BOOMR variables will be removed on 31/01/2025, after which `window.Shopify.theme.schema_name` and `window.Shopify.theme.schema_version` should be used exclusively.

**Deprecation of BOOMR Script:** The BOOMR (Boomerang) JavaScript library was used for collecting Web Performance data on storefronts and it’s now been replaced with a leaner and more conformant library. Some theme and app developers had been relying on a few variables set by BOOMR. These variables include:

* `BOOMR.themeName`
* `BOOMR.themeVersion`

These variables will continue to be available until 31st Janurary 2025, allowing developers to transition to the new method of accessing theme information.

**Introduction of Enhanced Theme Information on window\.Shopify.theme:** In response to developer feedback, we are enhancing the `window.Shopify.theme` object. Starting today, it will include two new properties:

* `schema_name`: Reflects the `name` attribute from the theme's `settings_schema.json`.
* `schema_version`: Reflects the `version` attribute from the theme's `settings_schema.json`.

These additions aim to provide a standardized and reliable method for accessing theme information directly from the Shopify global object.
