Game data updates to the wiki have been started.
A system has been added that will automatically add divination cards and other items to the item acquisition sections where appropriate. Entries added by this system will be shown as automatic in the item acquisition section.
Some pages will need to be updated to include
upgraded_from_disabled=true if they are not eligible for the system.
Some further details on what needs to be done can be found on Path of Exile Wiki:To-do list/Automatic upgraded from and issues can be posted on the talk page.
