+*Tech preview of new provenance features*
+
+This release offers a sneak peek at new image signing capabilities that are
+currently under development. Soon, these capabilities will allow any image
+author to sign their images to certify they have not been tampered with. For
+this release, Official images are now signed by Docker, Inc. Not only does this
+demonstrate the new functionality, we hope it will improve your confidence in
+the security of Official images. Look for the blue ribbons denoting signed
+images on the [Docker Hub](https://hub.docker.com/).
+The Docker Engine has been updated to automatically verify that a given
+Official Repo has a current, valid signature. When pulling a signed image,
+you'll see a message stating `the image you are pulling has been verified`. If
+no valid signature is detected, Docker Engine will fall back to pulling a
+regular, unsigned image.
