Late January — Mandatory actor support in all supported social tools; MediaWiki 1.34 or newer is required for version 1.14 of Extension:SocialProfile; system administrators should update all affected social tools and run maintenance/update.php afterwards to ensure that the actor columns will be properly populated
July — Social tools' MediaWiki compatibility policy changes: all social tools now aim to be compatible with the latest Long-Term Support (LTS) release of MediaWiki (1.35 at the time) instead of the latest stable release of MediaWiki. This change was necessary because given the limited resources, it's not feasible to anymore try to target the latest stable version of MediaWiki.
Late May — FanBoxes, PictureGame, PollNY and QuizGame now support using images already uploaded to the wiki instead of requiring the user to upload an image (or images, in the case of PictureGame) when creating a new userbox/picture game/poll/quiz question.
