Verified facts
What happened
The official Shopify Developer Changelog says API version 2026-10 adds a non-null translatable Boolean field to the Metafield object in the GraphQL Admin API.
Apps on 2026-10 or later that fetch translatable metafields can read that status directly from each metafield instead of using the deprecated TranslatableResourceType.METAFIELD value on translatableResources.
Apps on API version 2026-07 or earlier are unaffected by the new field; the deprecated enum continues to exist on those versions.
Shopify says the change adds no feature preview or access scope, and apps that do not query for translatable metafields do not need to change anything.
