 ### Updated OCI support
 
-- Support is added for [OCI Distribution Spec v1.1.0-rc3](https://github.com/opencontainers/distribution-spec/releases/tag/v1.1.0-rc3) and [OCI Image Spec v1.1.0-rc4](https://github.com/opencontainers/image-spec/releases/tag/v1.1.0-rc4). The OCI changes are summarized [here](https://opencontainers.org/posts/blog/2023-07-07-summary-of-upcoming-changes-in-oci-image-and-distribution-specs-v-1-1/).

-- Support is added for [OCI Artifacts and References](https://github.com/opencontainers/image-spec/blob/main/manifest.md#guidelines-for-artifact-usage). The OCI Image Spec v1.1.0 supports arbitrary artifact types and references so that software supply chain use cases can be supported (SBOMs, signatures, etc). Currently, [`oras`](https://github.com/oras-project/oras) and [`regclient`](https://github.com/regclient/regclient) support this spec.

 ### Built-in UI support
 
 - Using the new zot [GUI](../user-guides/user-guide-gui.md), you can browse a zot registry for container images and artifacts. The web interface provides the shell commands for downloading an image using popular third-party tools such as docker, podman, and skopeo.

 - The [`zli search`](../user-guides/zli.md#_zli-search) command allows smart searching for a repository by its name or for an image by its repo:tag.
 
+### Search by digest
+
+- You can perform a global search for a digest (SHA hash) using either the UI or the CLI. This function is useful when an issue is found in a layer that is used by multiple images. In the UI Search box, for example, begin typing `sha256:` followed by a partial or complete digest value to see a dropdown list of images that contain the layer with the digest value.

 ### GraphQL support for search
 
 - A [GraphQL backend server](../articles/graphql.md) within zot's registry search engine provides efficient and enhanced search capabilities. In addition to supporting direct GraphQL queries through the API, zot hosts the GraphQL Playground, which provides an interactive graphical environment for GraphQL queries.
