The History section has now been removed and the two articles that it held have been integrated into the FAQ, which in the future may end up having other essay-like answers to questions (both frequent and not so frequent ones) added.
The Concordance has finally been moved into ExpressionEngine. Old links to specific sections will no longer work, but it will now be easier to construct such links, as each section gets its very own URL. Additionally, it will be possible to see when each section was last updated. And yes, the AFfC update is finally in progress, so some sections have already had new material added.
