Why Did My SSL Certificate Get Re-issued?

I recently received a notification from GoDaddy about my 2-year SSL certificate being re-issued due to the new regulation capping certificates at 397 days. Just to clarify, this re-issue doesn't involve re-keying, so it shouldn't affect any existing certificates. I'm curious if anyone else has gotten similar notices and if this re-issuing trend is going to continue as the limitations become stricter. I'm also concerned about managing these updates moving forward since my setup doesn't easily automate certificate updates.
