And the name is followed by "topology version 6", right?

What do you suggest? My idea was "Build topology" item in context
menu. But we are over feature freeze and if somebody has already G6
vectors, he should know that he must rebuild topology in G7. It is
described here:

I fixed the crash and removed new layer menu items from the vector if
it is not valid.

Draw features? There should be usual Add Point, Add Line etc. tools in
Digitizing Toolbar.

Fixed, it was trying to show a warning from rendering non GUI thread.

Labels were never supported, you can fill feature request issue.

No, except for color labels. For now, if you find more issues, write
it here and I'll try to fix immediately.

Very welcome. There are still issues in editing, that is why I have
not announced yet the upgrade to be finished. The implementation of
editing became incredibly complex. Basic editing should mostly work
however.
