Firestorm has their new viewer out as of 1 AM (SLT?) Oct 1, 2019. The announcement is here Firestorm 6.3.2 Released. This is a major update and good news for Second Life™ users. However, it is a mess for OpenSim users as this version crashes OpenSim servers. It is explained in the FS announcement.

This version of Firestorm is a mix of current Linden Viewer features and features from RC versions of the Linden Viewer. So, this would be a viewer actually ahead of the Linden Viewer feature and bug-fix-wise. That hasn’t happened in a long time.
This version is a must-have update. Without this update, you will start to see avatars with blue and yellow textures poking through their skin and clothes. Over time the problem will get worse as more people move to BoM attire. Fortunately, most of the third-party viewers have implemented BoM support. Singularity does not yet have BoM support. I think it may be the only one.
