I recently got another yubikey and due to poor handling of the old key (can't load it onto the new card) I've generated a new key. I've revoked my old 2017 key (key id 0xBD51CB9670DF9DE7) and replaced with my new key (key id 0xDAE4D06F77191ACD)

My new key's fingerprint is:

AD05 74F1 0BC3 E41D 3D8E  78FD DAE4 D06F 7719 1ACD

and it is signed with the old (revoked) key. You can download the key directly from me or from keys.openpgp.org.
