Hello:
According with web page, last version for Ubuntu DraftSight is R 1.4.
Nevertheless, I have downloaded and installed available version but picking in "About" it says that R 1.3 is currently installed.
As downloaded file has not named including version number ["draftsight.deb" is the only name] I don't know if the link for download is not propperly pointed to R 1.4 or "about" information was not updated in rR1.4
Best regards and thank you
