Although the big news of last Thursday, if I recall correctly, Inkscape 0.44 is out and available. Last time I checked 0.44 is not yet available through Ubuntu’s package repositories but you can compile from svn easily enough. Alternatively if you’re lazy an autopackage is available.
Tarballs, dmg and exe files along with the autopackage .package file can be found on Inkscape.org’s download page. Download, install and get creative.
Edit: Closed the tab by accident; I forgot to mention the release notes can be found here.
