The OpenEMR project has released version 4.1.0. This version is 100% ONC-ATB Ambulatory EHR certified for 2011-2012 when used with a certified e-prescription solution. Kudos to the SourceForge project admin Rod Roark and Tony McCormick the project manager. The effort was accomplished by a consortium of small development companies with included SunsetSystems, MI-Squared, Visolve, Z&H Healthcare, Garden State Health Systems, and Ensoftek. There were a large number of individual contributors and there is at least a partial list on the copyright information page at http://www.oemr.org/wiki/OpenEMR_Copyright_Notice .
