After a long development cycle, the developers of the excellent free vector drawing program Inkscape have just released a major new version, numbered 0.91. There is a good article about the updates available from Libre Graphics World and you can download the new software (Windows, Mac, or Linux) from Inkscape.org.
I’ve installed the new Inkscape on the computer attached to the laser. Just in case you should have trouble with the new version, the old version (0.48.4) is also still available.
