+The 2.7 registry release has been a long time coming and represents both
+a long gap since the previous release and a renewed effort to release
+regularly. The maintainers were committed to get OCI support into the
+next release and thanks to much effort in the community that has
+been accomplished.
+
+## OCI Support
+
+### Push and Pull of OCI Images
+
+The registry now allows pushing and pulling OCI images. OCI images will always
+be preserved exactly without conversion to older types. With this change,
+clients which implement OCI can feel comfortable creating OCI images as part of
+their container image build process.
+
+## Specification Donation
+
+The Distribution specification which has had 4 years of review, implementation,
+and production use is now part of OCI. As part of that move, specification
+changes will no longer be accepted in the open source registry and should
+instead go to [OCI's distribution-spec](https://github.com/opencontainers/distribution-spec/issues).
+
+## Bug fixes
+
+Many many fixes and improvements, see the change log below
