Is developer.wordpress.org Up-to-Date?

I’ve been re-educating myself on the nuts and bolts of WP development, as I’ve been primarily in others CMS platforms for various clients. I was reading through developer.wordpress.com and came across this page:

Site Architecture (v1.5) – Advanced Administration Handbook

It talks about WP architecture 1.5. The publish date is 2023 with an update to the page in 2024. I don’t remember there being a separate architecture version, so it initially looked like documentation from 10 years ago.

I wanted to double check with the community to see if these were still relevant and the appropriate docs to study before investing the better part of a day getting reacquainted with them.

Thanks.
