This long-awaited project replaces the aging LLQTWebKit system used in the Web media plugin with a shiny new one based on the Chromium Embedded Framework (CEF) that supports modern web technologies. In fact, we think this is such a big deal that we're cranking the Viewer version number to 4.0.0.
See a bug? If you don't see it filed already - file a Jira! We look forward to your feedback. Thanks!
Note: Linux users who have not accepted the terms of service will need to go to my.secondlife.com to accept them on the web before logging in. CEF will not currently work on Linux, though the viewer will continue to function.
