This version may be great for Second Life but it sure is not very good for opensim at all.
This viewer crashed for me most of the time when I am trying to download my inventory cache. It seems the protocols have changed on the way the viewer received the cache files.
Here is what I noticed that after I cleared my cache folder then went to log into Metropolis grid. Soon as I logged in the viewer was reporting I have 1,500 items downloaded immediately then after about 5 min there was no progress at all. Also to note I was locked in place in world, then at that time the viewer decided to crash.
I went back to the previous version 5.0.1.52150 this seems to run ok
I hope Firestorm folks fix this problem for opensim tech
