This transition coincides with the movement away from Facebook’s older REST API to their new Graph API. Among the changes were a new Showcase page, a more rich Platform Live Status page, and most importantly new Platform Documentation. The Platform Documentation is currently being migrated away from the old Wiki style content to new static documentation as Facebook looks to deprecate the Wiki. To aide in the transition, Facebook has opened a documentation category in Bugzilla to collect all documentation-related “bugs” (omissions, errors, etc.) in one place.
Shortly after the update, many developers started noticing the absence of the Developer Tools in the new site. A bug was opened in Bugzilla to address the issue, and has since been resolved. Whereas the old Developer Tools resided on a central page, the new tools are spread through the documentation in the appropriate places. For example, the FQL Test Console is now located on the fql.query REST API page. Similar Test Consoles can be found for various old REST APIs. Note, the new Graph API does not have a Test Console as all data can be accessed via any web browser.
