# Release stage ### Definition Release stages in Reflag are entities that allow setting up [app](/product-handbook/concepts/app.md)-wide [feature access](/product-handbook/concepts/feature.md#access) targeting rules. Each release stage defines [targeting rules](/product-handbook/concepts/targeting-rules.md) for each available [environment](/product-handbook/concepts/environment.md). Later, during the development of new features, you can apply all those rule automatically by selecting an available release stage. Release stages are useful tools when a standard release workflow is used in your organization. ### Next steps * Learn about [filters](/product-handbook/concepts/filter.md) and [targeting rules](/product-handbook/concepts/targeting-rules.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
