For a number of reasons, including the use of better cryptographic algorithms and key management using a hardware security module exclusively, I have recently set up a new OpenPGP key and will be transitioning away from my old one.

The old key will continue to be valid for some time, but I prefer that the new key be used whenever possible.

The old key was 0x498A12A1584EA6F9:

pub   dsa1024/0x5FF14E6B8CE71E1C 2007-03-17
      Key fingerprint = 03CF 7D34 460F BCE6 E8B4  DA43 5FF1 4E6B 8CE7 1E1C

The new key is 0x498A12A1584EA6F9:

pub   rsa4096/0x498A12A1584EA6F9 2019-06-11
      Key fingerprint = E98C 0D0D 7CD6 8D7D DDCF  7034 498A 12A1 584E A6F9

The full text of this transition statement, signed by both keys and including instructions for use and verification, is also available.
