Container Linux release images will be signed with a new key due to
scheduled subkey rotation in all channels, starting with the alpha
release in two weeks (May 7). With today's promotion of version
2079.3.0 to stable, the tools shipped with Container Linux in all
channels support the new subkey.

The new subkey is 67B3CA0E, which was added to the overall key
93D2DCB4. You can update the key from public PGP key servers or
retrieve it from the following URL:

https://coreos.com/security/image-signing-key/

If you have processes that download Container Linux images, please
ensure you are using the updated key to continue cryptographically
verifying the artifacts.
