What is new "Ranking" section that Google's March 2023 core update is Processing?

Google Search Central

We're working on unifying the ranking updates page with http://status.search.google.com. Soon, the new "Ranking" section will show the active March 2023 core update, plus history up to 2020. We'll update this tweet once we're finished migrating.

it showed the core update on 22nd and my site https://www.timkost.com/ dropped on 23rd. What a coincidence. From 1K to 10 traffic a day. T.T I am thinking new domains with months old will be most affected.
