Websocket Protocol Updates Question

Hello!

Got the popup upon login about "Websocket protocols for Adobe Marketo Engage are updating on December 31, 2023. Please work with your IT team to allowlist required Marketo Engage and Adobe domains and ports to prevent access disruptions."

I see that the linked "Configure Protocol" page was last updated on Nov 15th, 2023, but I was curious if there was a more detailed list of what's changing / needs updating before or after the 31st?

Is there any sort of change log on that page to see what changed? Or should I just shoot that over to my IT Team to make sure it's all good with what is on the latest page?
