Commons 2.5 was released today. This is a significant release for a number of reasons, including some significant UX improvements. We also added Question & Answer functionality which is very important for both internal and external communities. There was a significant UX focus on this release with usability testing being very helpful. This was very informative and initiated a change in login/landing on the Activity Stream to a site landing page. This was validated in the usability testing, discussions with users and a survey of successful community sites. Here is a screenshot, you will now see your groups sorted by activity date (formerly alphabetical), Who's online, your posts & bookmarks along with featured content on the landing page.

We are really looking for feedback!
