Main & Beta
The current main viewer for Second Life is version 3.2.1.244864. Of course, this version is available from the main Second Life download page. Also on that page is the Beta version of the viewer, which is now version 3.2.2.244666. And the link to the wiki page Linden Lab Official: Alternate Viewers with development, project, and alternate third party viewers is there.
Currently Second Life viewers are running slow. In my previous article I was researching how to get more speed out of my viewer. The information you need to diagnose your computer’s performance is there. How to get a Faster Second Life
Direct Delivery
The Direct Delivery Project Viewer is currently at version 3.0.2.239555. This viewer is currently for use on the ADITI grid where the servers are setup to test Direct Delivery.
Project viewers tend to come in two versions, the current Project Viewer and the Latest Build version. The latest build is similar to what many call a nightly build version. Today the Direct Delivery project’s Latest Viewer page is not loading.
