Welcome to OptiNav's BeamformX forum.
The site www.optinav.info has been developed as a repository for OptiNav resources. It has some videos and download links, including the latest version of BeamformX. The page for BeamformX version history, www.optinav.info/ftp.html , has been been redirected to optinav.info. You may want to update any links to remove the /ftp.html part. The version history is still accessible from optinav.info.
