Developers can now request permission to access lists of users’ subscribers and who they subscribe to via the Graph API. Facebook announced this and a few other changes in a blog post Wednesday.

With read permissions for subscriptions, apps can create more personalized experiences for users. They can also track subscriptions over time. Since Facebook does not offer analytics for users who enable subscribers, people could turn to apps to track their growth. Klout might be another third-party that would be interested in incorporating subscriber data because the company could use this information as another factor to calculate a person’s influence.

Facebook also made improvements to the search function on its developer site. Search results now include bugs and technical Q&A from Stack Overflow. Developers can also filter results by type.

The “manage_notifications” permission is now required to read or manage users’ notifications. The change was announced in July 2011 and migration is complete, according to the blog post.

The social network is in the process of deprecating the old page Insights. It confirmed that the old Insights will be completely removed on Feb. 15.
