 ## Unreleased
 - dev: Refactor database ID resolution when the GraphQL `ID` type is indeterminate. Note: The following input args now work with both database and global IDs: `GfEntriesConnectionWhereArgs.formIds`, `GfFormsConnectionwhereArgs.formIds`.
 - docs: Add missing documentation regarding using `productValues` input when submitting forms.
+- dev: Remove usage of deprecated `WPGraphQL\Data\DataSource::resolve_post_object()` method.
 
 ## v0.12.1 - Bug fix
