Awesome, thanks!

I just installed it. I needed to uninstall the previous package first (some conflicting packages message). No problem to do that manually though.
After installing all settings were still working (.emacs not overwritten) so that was nice

Checked some documents and also gave eww a try - it has some very nice improvements.

I guess no Xwidgets support possible?

Everything seems to be working fine (of course not played with it for a long time). Will test it some more the next few days and report back if there are any problems with it.
