The original plan was for the release team to compile a list of requested features by building upon the following wishlist started by Richard Heigl and Krabina Bernhard: https://www.mediawiki.org/wiki/MediaWiki_Cooperation/Tasks/Feature_wishlist
However this task has been set aside as multiple small tasks for the students of Google Code-in 2014 to help with. There are twelve (12) tasks, each task with an assigned month.
For each task, the student is to search the archives of the MediaWiki-l mailing list at **https://lists.wikimedia.org/mailman/listinfo/mediawiki-l** and the MediaWiki Supportdesk wiki page at https://www.mediawiki.org/wiki/Project:Support_desk for mentions of feature requests or pain points that new features could address.
Results are reported on the following page: https://www.mediawiki.org/wiki/MediaWiki_Stakeholders%27_Group/Tasks/Feature_wishlist/NAME
