+# Docker Registry Deprecation
+
+This document details functionality or components which are deprecated within
+the registry.
+
+### v2.5.0
+
+The signature store has been removed from the registry.  Since `v2.4.0` it has
+been possible to configure the registry to generate manifest signatures rather
+than load them from storage.   In this version of the registry this becomes
+the default behavior.  Signatures which are attached to manifests on put are
+not stored in the registry.  This does not alter the functional behavior of
+the registry.
+
+Old signatures blobs can be removed from the registry storage by running the
+garbage-collect subcommand.
