 # Global Styles Filters
 
-WordPress 6.1 has introduced some server-side filters to hook into the data provided to Global Styles & Settings:
+WordPress 6.1 has introduced some server-side filters to hook into the `theme.json` data provided at the different data layers:
 
-- `global_styles_default`: hooks into the default data provided by WordPress
-- `global_styles_blocks`: hooks into the data provided by the blocks
-- `global_styles_theme`: hooks into the data provided by the theme
-- `global_styles_user`: hooks into the data provided by the user
+- `theme_json_default`: hooks into the default data provided by WordPress
+- `theme_json_blocks`: hooks into the data provided by the blocks
+- `theme_json_theme`: hooks into the data provided by the theme
+- `theme_json_user`: hooks into the data provided by the user
 
 Each filter receives an instance of the `WP_Theme_JSON_Data` class with the data for the respective layer. To provide new data, the filter callback needs to use the `update_with( $new_data )` method, where `$new_data` is a valid `theme.json`-like structure. As with any `theme.json`, the new data needs to declare which `version` of the `theme.json` is using, so it can correctly be migrated to the runtime one, should it be different.
