The build process’ linking for the Development Viewer is not working correctly. So, the Snowstorm Page is not updating as it should. It is stuck on 3.3.2 (250772). However, there have been a number of builds and improvements in the Dev Viewer. We just can’t get to them.
However, you can get the latest Development Integration Viewer. This is not a daily use viewer. But, the current rumor is it is stable. I find it is only using 650±mb of ram. That is way down from 1.2 to 2.1mb I have seen in previous versions.
Another branch named Viewmaster is the branch the bug chasers are working on. It is said to be very very stable. Now if I can just figure out the link.
