If I create a new document and "Save As..." (Inkscape SVG), then the resulting XML <svg> tag appears to indicate SVG 1.1 and not SVG 2.

<svg
   xmlns:svg="http://www.w3.org/2000/svg"
   xmlns="http://www.w3.org/2000/svg"
   xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape"
   inkscape:version="1.0rc1 (09960d6, 2020-04-09)"
   version="1.1"
   >

Is it possible to expressly create an SVG 2 document in Inkscape 1.x?

Also, does any summary information exist on the extent to which Inkscape 1.x supports the more recent 16 February 2020 W3C Editor’s Draft for SVG 2 ?

This might be a bug to be honest. I know we're using svg2 things.

Hi

Which SVG version does Inkscape 1.01 use? I see some characteristics deprecated in last SVG, like  ‘xlink:type’, ‘xlink:role’, ‘xlink:arcrole’, ‘xlink:show’ and ‘xlink:actuate’, or xlink:href that has changed to href o xlink:title to title. 
Will next Inkscape version produce SVG 2 images?

Bye

@juankar Inkscape is supporting as much of both SVG 1.1 and SVG 2.0 as it can. It's likely going to continue to support SVG 1.1 features which may have been removed in 2.0, although opening href without xlink is a reported bug (and I tried and failed to fix it last year too)
