On January 1, 2012, QVCS-Pro and QVCS were made freeware. QVCS-Enterprise followed suit on June 16, 2012, and then was open sourced under the Apache 2.0 License on March 2, 2014.
At some time after June 23, 2013, the domain name qumasoft.com was abandoned. It is now (June 2015) owned by a weight loss company. The contents of the Web site when it was operated by the author of QVCS is available on the Wayback Machine.
