Another third party viewer (TPV) releases a mesh capable viewer. Dolphin 3 Viewer is the latest. See the announcement on the Dolphin Viewer blog.
The article lists the features now in Dolphin Viewer 3. Some are features that have been in the SLViewer 2 and 3 for a time. Some are Dolphin features not in the SLViewer. The current combination of features makes Dolphin Viewer 3 one of more feature rich power-user viewers.
BIG TIP for Blocked Login
I’ve seen a number of people complaining about not being able to login. This is a problem thought to be in the Linden Lab code for version 3 viewers, basically mesh capable viewers. Once one runs into the problem it seems to be very difficult to get around it and get logged in. This problem is not Dolphin Viewer problem. It is an SL problem.
