• authlog - provides identity authentication logging and tracking mechanism, which can be used for 'brute-force' attack protection.
• file-storage - File storage abstraction.
• ar-file - ActiveRecord behavior, which provides file attachment.

Additionally, there's new ar-eagerjoin extension which allows ActiveRecord relation eager loading via join without extra query.
