Why did they nerf wiki ? Is the older version still there ?

Hi, all important informational parts will be added to the wiki when players create new ones in the current content model. Feel free to contribute yourself by creating articles. We also have plans to implement a global search bar and the penetration calculator will return, amongst other things that we're looking to improve.

The old Wiki can be found here: https://old-wiki.warthunder.com/Main_Page
