This is a summary of recent additions and changes to the site. The list isn't comprehensive - we report only the more visible and significant changes, so you might notice some minor changes from time to time that aren't reported here.
Reorganized header links: Most of the header links only make sense if you're logged in (Profile, Settings, My Activity, Inbox), so we now hide all of those and just show a "Log In" link when you're logged out. When you're logged in on mobile, we put all of those links in a new "Menu" menu.
