    OpenProj has had no development since 2012 and does not offer any type of “printing” options virtually all reports are on screen only so they are difficult or impossible to send to other or to import into other documents. On the other hand, ProjectLibre has been under continuous support and development, includes printing options, and has active community support. Failure of the author to give an accurate history of these products, in an article written 7 years after the fork, significantly lowers the credibility of the report.
