# 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.
