+==== Docker v2 registries deprecated
+
+Support for Docker v2 registries is deprecated and will be removed in {product-title} {product-version}.21. A registry that supports the Open Container Initiative (OCI) specification will be required for all mirroring operations as of {product-title} {product-version}.21. Additionally, `oc-mirror` v2 now only generates custom catalog images in the OCI format, whereas the deprecated `oc-mirror` v1 still supports the Docker v2 format.
