Where are the good old manuals?

Hi,
where are the good old detailed manuals on Wordpress/Multisite, BuddyPress and more?
I mean the ones that were accessible on your site some months ago at URLs like
https://premium.wpmudev.org/manuals/wpmu-manual-2/...
https://premium.wpmudev.org/manuals/the-buddypress-manual-2/...
Regards,
Stefan.
