+## Release pipelines
+
+### Secret management (Vault migration)
+
+The release credentials for this repository have been migrated to HashiCorp Vault.
+
+**Important:** The legacy GitHub Actions secrets have been intentionally retained and **should not be deleted** for the following reasons:
+
+- There are multiple active release pipelines for Camunda Platform 7 that still depend on this setup.
+- Some of those pipelines are in extended support and, while not actively releasing at this time, may still be needed for future releases.
+- Migrating all pipelines is out of scope for the current work cycle.
+- Retaining the old secrets preserves the ability to **roll back** to the pre-Vault configuration if the current changes are found to break any release pipeline. Given the age and release-driven nature of these pipelines, this cannot be verified immediately.
+
+Until all pipelines are verified and fully migrated, please **do not remove the existing GitHub Actions secrets**.
